کپیتالیسم (به انگلیسی: Capitalism) یا سرمایهداری، سرمایهمحوری یک نظام اقتصادی است که در آن پایههای یک سیستم اقتصادی بر روی مالکیت خصوصی ابزارهای تولیدِ اقتصادی است و در دست مالکان خصوصی است و از این برای ایجاد بهرهمندی اقتصادی در بازارهایی رقابتی استفاده میشود؛ که به این قانون، آزادی مالکیت شخصی نیز گفته میشود؛ که معنای آن، تولید و توزیع کالا هاست.
معنای لغوی کپیتال همان سرمایه است و سرمایه شامل: زمینها، کارخانهها و… میباشد. درآمد در این قانون حداقل دو شکل دارد: سود و دستمزد. سود عبارت است از آنچه که بهخاطر مالکیت ابزار تولید به کسانی که سرمایه را فراهم کردهاند، داده میشود. در این قانون زمین، نیروی انسانی و سرمایه در اختیار گروهی از افراد جامعه است که سایر افراد جامعه با استفادهٔ مشروط از آنها، به تولید مادی و تولید معنوی میپردازند.
همچنین در این قانون متداول است که اجاره را به صورت درآمد حاصل از در کنترل داشتن منابع طبیعی به حساب بیاورند که با دو مورد دیگر متفاوت است.
در قانون سرمایهداری، سرمایهگذاری، تولید، توزیع، درآمد، قیمتگذاری و عرضهٔ مواد و خدمات توسط تصمیمگیریهایِ شخصی در یک اقتصاد بازار تعیین میشود. مشخصهٔ بارز قانون سرمایهداری این است که تولید کالا در درجهٔ اول از برای کسب سود اقتصادی انجام میگیرد و نه لزوماً رفع نیازهای انسانها. البته در مواردی نیز، کسب سود با رفع نیازهای انسانی همراه است.
در کلیترین حالت، نظام سرمایهداری را میتوان به دو دستهٔ نظام سرمایهداری دولتی (همچون اتحاد جماهیر شوروی پس از ۱۹۲۷ یا چین کنونی) و نظام سرمایهداری غیر متمرکز و غیردولتی همچون ایالات متحدهٔ آمریکا تقسیم نمود.
این مفهوم در عامترین معنایش تنها از آغاز سدهٔ بیستم وجود دارد. تاریخ آن را میتوان تقریباً سال ۱۹۰۲ دانست زمانی که هربرت سومبارت کتاب معروف خود «سرمایهداری مدرن» را منتشر کرد. به عکس این واژه را مارکس عملاً بکار نبردهاست. اقتصاد سرمایهداری عملاً بین قرون ۱۶ و ۱۹ میلادی در انگلیس به تدریج رسمی شد. با وجود اینکه برخی ویژگیهای این قانون در دوران خیلی گذشته نیز دیده میشود، شکلهای ابتدایی سرمایهداری تجاری (merchant capitalism) در اواخر قرون وسطی شکوفا شد.
سرمایهداری از پایان دورهٔ فئودالیسم در دنیای غرب نظام غالب بودهاست. به تدریج این قانون از انگلیس به سراسر اروپا گسترش یافته مرزهای سیاسی و فرهنگی را درنوردید. در قرون ۱۹ و ۲۰ میلادی سرمایهداری ابزار غالب، ولی نه انحصاری، صنعتی شدن را در دنیا فراهم آوردهاست.
ثروت اروپای غربی به سرعت فزونی یافت: طلا و نقره از آمریکای جنوبی گرفته شد تا بانکها را تغذیه کنند، و بردگان مورد نیاز بودند تا برای کارگاههای اروپای غربی کالاهای مصرفی و مواد خام تولید کنند. تجارت جهانی را تصرف مستعمرههای جدید، توسعهٔ مستعمرههای کهن، و گسترش بردهداری و دزدی و راهزنی آشکارا به پیش راند. اینها ویژگیهای برجسته بازارهایی است که بیش از دو سده تکامل یافت، یکی از ویژگیهای اصلی این مرحلهٔ تجاری سرمایهداری این است که این مرحله نه فقط بازارها را تأمین میکند بلکه همچنین ثروتی را فراهم میآورد که انقلابی صنعتی را تغذیه میکند که در میانهٔ سدهٔ ۱۷۰۰ آغاز میشود.
حامیان و منتقدان[ویرایش]
بسیاری از نظریه پردازان و سیاستمداران که غالباً در کشورهای دارای قانون سرمایهداری زندگی میکنند، بر این باورند که قوانین سرمایهداری از طریق شاخصهایی مانند تولید ناخالص داخلی، سطح رفاه زندگی و درجهٔ بهکارگیری ظرفیتها، تأثیر بسزایی در رشد اقتصادی دارد. برای نمونه سطح زندگی در اروپا در طی سه قرن گذشته بسیار بهبود یافته.
برای نمونه آدام اسمیت برای دفاع از اینکه باید اجازه داد بازار آزاد تولید، قیمتگذاری و تخصیص منابع را کنترل کند، از این برهان استفاده کرد. آمار نشان میدهد از آغاز سرمایهداری، سرانهٔ تولید ناخالص داخلی آن کشور، شتاب بالایی را تجربه میکند.
منتقدان قانون سرمایهداری بر این باورند که در قرن بیستم قانون سرمایهداری پا به مرحلهای جدید گذاشتهاست و به قانون سرمایهداری انحصاری بدل گردیدهاست.
در قانون سرمایهداری انحصاری، عملاً مفهوم بازار آزاد که توسط نظریه پردازان اولیهای قانون سرمایهداری همچون آدام اسمیت مورد حمایت واقع میشد، مفهوم ابتدایی خود را از دست داد و رقابت که مفهوم کلیدی اقتصاد بازار و قانون عرضه و تقاضا بود به رقابت بین شرکتهای انحصاری و کارتلها تنزل یافت.
منتقدان اصلی قانون سرمایهداری شامل سوسیالیستها (از جمله کارل مارکس، فردریک انگلس، ولادیمیر لنین، مائو تسهتونگ، فیدل کاسترو) و آنارشیستها (مانند بنجامین تاکر، نوام چامسکی) میشود. برخی ادیان نیز با قسمتهایی از این قانون مخالفند. مثلاً ادیان یهودی، مسیحی و اسلام، نرخ بهره را حرام میدانند.
برخی از انتقاداتی که به این قانون میشود عبارتند از:
منتقدین بر این باورند که ترکیب تجارت آزاد و داراییهای خصوصی سرمایه داران ذاتاً منجر به ساختارهای انحصارطلب میشود. مباحث اقتصاد سیاسی به مطالعهٔ این موضوع میپردازد که قانون سرمایهداری تا چه اندازه مسئول استثمار اقتصادی، جنگهای امپریالیستی، استعمارگرایانه و ضدانقلابی، همچنین سرکوب کارگران، اتحادیههای صنفی و نسلکشی است.
از جمله نقاط ضعف یا قدرت قانون سرمایهداری دورههای بحران در این قانون است که به نظر برخی همچون مارکس نقطه ضعف آن میباشد که بر این پایه او تئوری بحران را مطرح کرد که سبب فروپاشی قانون سرمایهداری میگردد، از دید برخی دیگر دورههای بحران سبب تقویت ارکان قانون سرمایهداری میشود.
به عقیده مارکس با هر بحران پایههای سرمایهداری متزلزل میشود و در خلال یکی از این بحرانهای وخیم اقتصادی با اقدام به اعتصاب و شدت عمل کارگری، مالکیت ابزار تولید از آن معدود مالکانی که بر اثر قانون تمرکز سرمایه باقیماندهاند به هیئت اجتماعیه انتقال داده میشود.

Capitalism is an economic system based on the private ownership of the means of production and their operation for profit. Characteristics central to capitalism include private property, capital accumulation, wage labor, voluntary exchange, a price system and competitive markets. In a capitalist market economy, decision-making and investments are determined by every owner of wealth, property or production ability in financial and capital markets, whereas prices and the distribution of goods and services are mainly determined by competition in goods and services markets.
Economists, political economists, sociologists and historians have adopted different perspectives in their analyses of capitalism and have recognized various forms of it in practice. These include laissez-faire or free-market capitalism, welfare capitalism and state capitalism. Different forms of capitalism feature varying degrees of free markets, public ownership, obstacles to free competition and state-sanctioned social policies. The degree of competition in markets, the role of intervention and regulation, and the scope of state ownership vary across different models of capitalism. The extent to which different markets are free as well as the rules defining private property are matters of politics and policy. Most existing capitalist economies are mixed economies which combine elements of free markets with state intervention and in some cases economic planning.
Market economies have existed under many forms of government and in many different times, places and cultures. Modern capitalist societies—marked by a universalization of money-based social relations, a consistently large and system-wide class of workers who must work for wages, and a capitalist class which owns the means of production—developed in Western Europe in a process that led to the Industrial Revolution. Capitalist systems with varying degrees of direct government intervention have since become dominant in the Western world and continue to spread. Over time, capitalist countries have experienced consistent economic growth and an increase in the standard of living.
Critics of capitalism argue that it establishes power in the hands of a minority capitalist class that exists through the exploitation of the majority working class and their labor; prioritizes profit over social good, natural resources and the environment; and is an engine of inequality, corruption and economic instabilities. Supporters argue that it provides better products and innovation through competition, disperses wealth to all productive people, promotes pluralism and decentralization of power, creates strong economic growth and yields productivity and prosperity that greatly benefit society.
The term "capitalist", meaning an owner of capital, appears earlier than the term "capitalism" and it dates back to the mid-17th century. "Capitalism" is derived from capital, which evolved from capitale, a late Latin word based on caput, meaning "head"—also the origin of "chattel" and "cattle" in the sense of movable property (only much later to refer only to livestock). Capitale emerged in the 12th to 13th centuries in the sense of referring to funds, stock of merchandise, sum of money or money carrying interest.:232 By 1283, it was used in the sense of the capital assets of a trading firm and it was frequently interchanged with a number of other words—wealth, money, funds, goods, assets, property and so on.:233
The Hollandische Mercurius uses "capitalists" in 1633 and 1654 to refer to owners of capital.:234 In French, Étienne Clavier referred to capitalistes in 1788, six years before its first recorded English usage by Arthur Young in his work Travels in France (1792). In his Principles of Political Economy and Taxation (1817), David Ricardo referred to "the capitalist" many times. Samuel Taylor Coleridge, an English poet, used "capitalist" in his work Table Talk (1823). Pierre-Joseph Proudhon used the term "capitalist" in his first work, What is Property? (1840), to refer to the owners of capital. Benjamin Disraeli used the term "capitalist" in his 1845 work Sybil.
The initial usage of the term "capitalism" in its modern sense has been attributed to Louis Blanc in 1850 ("What I call 'capitalism' that is to say the appropriation of capital by some to the exclusion of others") and Pierre-Joseph Proudhon in 1861 ("Economic and social regime in which capital, the source of income, does not generally belong to those who make it work through their labour").:237 Karl Marx and Friedrich Engels referred to the "capitalistic system" and to the "capitalist mode of production" in Capital (1867). The use of the word "capitalism" in reference to an economic system appears twice in Volume I of Capital, p. 124 (German edition) and in Theories of Surplus Value, tome II, p. 493 (German edition). Marx did not extensively use the form capitalism, but instead those of capitalist and capitalist mode of production, which appear more than 2,600 times in the trilogy The Capital. According to the Oxford English Dictionary (OED), the term "capitalism" first appeared in English in 1854 in the novel The Newcomes by novelist William Makepeace Thackeray, where he meant "having ownership of capital". Also according to the OED, Carl Adolph Douai, a German American socialist and abolitionist, used the phrase "private capitalism" in 1863.
Capitalism in its modern form can be traced to the emergence of agrarian capitalism and mercantilism in the early Renaissance, in city states like Florence. Capital has existed incipiently on a small scale for centuries in the form of merchant, renting and lending activities and occasionally as small-scale industry with some wage labour. Simple commodity exchange and consequently simple commodity production, which are the initial basis for the growth of capital from trade, have a very long history. Arabs promulgated capitalist economic policies such as free trade and banking. Their use of Indo-Arabic numerals facilitated bookkeeping. These innovations migrated to Europe through trade partners in cities such as Venice and Pisa. The Italian mathematician Fibonacci traveled the Mediterranean talking to Arab traders, and returned to popularize the use of Indo-Arabic numerals in Europe.
Capital and commercial trade thus existed for much of history, but it did not lead to industrialisation or dominate the production process of society. That required a set of conditions, including specific technologies of mass production, the ability to independently and privately own and trade in means of production, a class of workers willing to sell their labour power for a living, a legal framework promoting commerce, a physical infrastructure allowing the circulation of goods on a large scale and security for private accumulation. Many of these conditions do not currently exist in many Third World countries, although there is plenty of capital and labour. The obstacles for the development of capitalist markets are therefore less technical and more social, cultural and political.
The economic foundations of the feudal agricultural system began to shift substantially in 16th-century England as the manorial system had broken down and land began to become concentrated in the hands of fewer landlords with increasingly large estates. Instead of a serf-based system of labor, workers were increasingly employed as part of a broader and expanding money-based economy. The system put pressure on both landlords and tenants to increase the productivity of agriculture to make profit; the weakened coercive power of the aristocracy to extract peasant surpluses encouraged them to try better methods; and the tenants also had incentive to improve their methods in order to flourish in a competitive labor market. Terms of rent for land were becoming subject to economic market forces rather than to the previous stagnant system of custom and feudal obligation.
By the early 17th century, England was a centralized state in which much of the feudal order of Medieval Europe had been swept away. This centralization was strengthened by a good system of roads and by a disproportionately large capital city, London. The capital acted as a central market hub for the entire country, creating a very large internal market for goods, contrasting with the fragmented feudal holdings that prevailed in most parts of the Continent.
The economic doctrine prevailing from the 16th to the 18th centuries is commonly called mercantilism. This period, the Age of Discovery, was associated with the geographic exploration of the foreign lands by merchant traders, especially from England and the Low Countries. Mercantilism was a system of trade for profit, although commodities were still largely produced by non-capitalist methods. Most scholars consider the era of merchant capitalism and mercantilism as the origin of modern capitalism, although Karl Polanyi argued that the hallmark of capitalism is the establishment of generalized markets for what he called the "fictitious commodities", i.e. land, labor and money. Accordingly, he argued that "not until 1834 was a competitive labor market established in England, hence industrial capitalism as a social system cannot be said to have existed before that date".
England began a large-scale and integrative approach to mercantilism during the Elizabethan Era (1558–1603). A systematic and coherent explanation of balance of trade was made public through Thomas Mun's argument England's Treasure by Forraign Trade, or the Balance of our Forraign Trade is The Rule of Our Treasure. It was written in the 1620s and published in 1664.
European merchants, backed by state controls, subsidies and monopolies, made most of their profits by buying and selling goods. In the words of Francis Bacon, the purpose of mercantilism was "the opening and well-balancing of trade; the cherishing of manufacturers; the banishing of idleness; the repressing of waste and excess by sumptuary laws; the improvement and husbanding of the soil; the regulation of prices...".
After the period of the proto-industrialization, the British East India Company and the Dutch East India Company, after massive contributions from the Mughal Bengal, inaugurated an expansive era of commerce and trade. These companies were characterized by their colonial and expansionary powers given to them by nation-states. During this era, merchants, who had traded under the previous stage of mercantilism, invested capital in the East India Companies and other colonies, seeking a return on investment.
In the mid-18th century a group of economic theorists, led by David Hume (1711-1776) and Adam Smith (1723-1790), challenged fundamental mercantilist doctrines - such as the belief that the world's wealth remained constant and that a state could only increase its wealth at the expense of another state.
During the Industrial Revolution, industrialists replaced merchants as a dominant factor in the capitalist system and affected the decline of the traditional handicraft skills of artisans, guilds and journeymen. Also during this period, the surplus generated by the rise of commercial agriculture encouraged increased mechanization of agriculture. Industrial capitalism marked the development of the factory system of manufacturing, characterized by a complex division of labor between and within work process and the routine of work tasks; and eventually established the domination of the capitalist mode of production.
Industrial Britain eventually abandoned the protectionist policy formerly prescribed by mercantilism. In the 19th century, Richard Cobden (1804-1865) and John Bright (1811-1889), who based their beliefs on the Manchester School, initiated a movement to lower tariffs. In the 1840s Britain adopted a less protectionist policy, with the 1846 repeal of the Corn Laws and the 1849 repeal of the Navigation Acts. Britain reduced tariffs and quotas, in line with David Ricardo's advocacy of free trade.
Capitalism was carried across the world by broader processes of globalization and by the beginning of the nineteenth century a series of loosely connected market systems had come together as a relatively integrated global system, in turn intensifying processes of economic and other globalization.[page needed] Later in the 20th century, capitalism overcame a challenge by centrally-planned economies and is now the encompassing system worldwide, with the mixed economy being its dominant form in the industrialized Western world.
Industrialization allowed cheap production of household items using economies of scale while rapid population growth created sustained demand for commodities. Globalization in this period was decisively shaped by 18th-century imperialism.[page needed]
After the First and Second Opium Wars and the completion of British conquest of India, vast populations of these regions became ready consumers of European exports. Also in this period, areas of sub-Saharan Africa and the Pacific islands were colonised. The conquest of new parts of the globe, notably sub-Saharan Africa, by Europeans yielded valuable natural resources such as rubber, diamonds and coal and helped fuel trade and investment between the European imperial powers, their colonies and the United States:
In this period, the global financial system was mainly tied to the gold standard. The United Kingdom first formally adopted this standard in 1821. Soon to follow were Canada in 1853, Newfoundland in 1865, the United States and Germany (de jure) in 1873. New technologies, such as the telegraph, the transatlantic cable, the radiotelephone, the steamship and railway allowed goods and information to move around the world at an unprecedented degree.
In the period following the global depression of the 1930s, the state played an increasingly prominent role in the capitalistic system throughout much of the world. The postwar boom ended in the late 1960s and early 1970s and the situation was worsened by the rise of stagflation. Monetarism, a modification of Keynesianism that is more compatible with laissez-faire, gained increasing prominence in the capitalist world, especially under the leadership of Ronald Reagan in the United States and Margaret Thatcher in the United Kingdom in the 1980s. Public and political interest began shifting away from the so-called collectivist concerns of Keynes's managed capitalism to a focus on individual choice, called "remarketized capitalism".
According to Harvard academic Shoshana Zuboff, a new genus of capitalism, surveillance capitalism, monetizes data acquired through surveillance. She states it was first discovered and consolidated at Google, emerged due to the "coupling of the vast powers of the digital with the radical indifference and intrinsic narcissism of the financial capitalism and its neoliberal vision that have dominated commerce for at least three decades, especially in the Anglo economies" and depends on the global architecture of computer mediation which produces a distributed and largely uncontested new expression of power she calls "Big Other".
Relationship to democracy
The relationship between democracy and capitalism is a contentious area in theory and in popular political movements. The extension of universal adult male suffrage in 19th-century Britain occurred along with the development of industrial capitalism and democracy became widespread at the same time as capitalism, leading capitalists to posit a causal or mutual relationship between them. However, according to some authors in the 20th-century, capitalism also accompanied a variety of political formations quite distinct from liberal democracies, including fascist regimes, absolute monarchies and single-party states. Democratic peace theory asserts that democracies seldom fight other democracies, but critics of that theory suggest that this may be because of political similarity or stability rather than because they are democratic or capitalist. Moderate critics argue that though economic growth under capitalism has led to democracy in the past, it may not do so in the future as authoritarian regimes have been able to manage economic growth using some of capitalism's competitive principles without making concessions to greater political freedom.
Milton Friedman, one of the biggest supporters of the idea that capitalism promotes political freedom, argued that competitive capitalism allows economic and political power to be separate, ensuring that they do not clash with one another. Moderate critics have recently challenged this, stating that the current influence lobbying groups have had on policy in the United States is a contradiction, given the approval of Citizens United. This has led people to question the idea that competitive capitalism promotes political freedom. The ruling on Citizens United allows corporations to spend undisclosed and unregulated amounts of money on political campaigns, shifting outcomes to the interests and undermining true democracy. As explained in Robin Hahnel’s writings, the centerpiece of the ideological defense of the free market system is the concept of economic freedom and that supporters equate economic democracy with economic freedom and claim that only the free market system can provide economic freedom. According to Hahnel, there are a few objections to the premise that capitalism offers freedom through economic freedom. These objections are guided by critical questions about who or what decides whose freedoms are more protected. Often, the question of inequality is brought up when discussing how well capitalism promotes democracy. An argument that could stand is that economic growth can lead to inequality given that capital can be acquired at different rates by different people. In Capital in the Twenty-First Century, Thomas Piketty of the Paris School of Economics asserts that inequality is the inevitable consequence of economic growth in a capitalist economy and the resulting concentration of wealth can destabilize democratic societies and undermine the ideals of social justice upon which they are built.
States with capitalistic economic systems have thrived under political regimes deemed to be authoritarian or oppressive. Singapore has a successful open market economy as a result of its competitive, business-friendly climate and robust rule of law. Nonetheless, it often comes under fire for its brand of government which though democratic and consistently one of the least corrupt it also operates largely under a one-party rule and does not vigorously defend freedom of expression given its government-regulated press as well as penchant for upholding laws protecting ethnic and religious harmony, judicial dignity and personal reputation. The private (capitalist) sector in the People's Republic of China has grown exponentially and thrived since its inception, despite having an authoritarian government. Augusto Pinochet's rule in Chile led to economic growth and high levels of inequality by using authoritarian means to create a safe environment for investment and capitalism. Similarly, Suharto's authoritarian reign and extirpation of the Communist Party of Indonesia allowed for the expansion of capitalism in Indonesia.
Varieties of capitalism
Peter A. Hall and David Soskice argued that modern economies have developed two different forms of capitalism: liberal market economies (or LME) (e.g. the United States, the United Kingdom, Canada, New Zealand and Ireland) and coordinated market economies (CME) (e.g. Germany, Japan, Sweden and Austria). Those two types can be distinguished by the primary way in which firms coordinate with each other and other actors, such as trade unions. In LMEs, firms primarily coordinate their endeavors by way of hierarchies and market mechanisms. Coordinated market economies more heavily rely on non-market forms of interaction in the coordination of their relationship with other actors (for a detailed description see Varieties of Capitalism). These two forms of capitalisms developed different industrial relations, vocational training and education, corporate governance, inter-firm relations and relations with employees. The existence of these different forms of capitalism has important societal effects, especially in periods of crisis and instability. Since the early 2000s, the number of labor market outsiders has rapidly grown in Europe, especially among the youth, potentially influencing social and political participation. Using varieties of capitalism theory, it is possible to disentangle the different effects on social and political participation that an increase of labor market outsiders has in liberal and coordinated market economies (Ferragina et al., 2016). The social and political disaffection, especially among the youth, seems to be more pronounced in liberal than coordinated market economies. This signals an important problem for liberal market economies in a period of crisis. If the market does not provide consistent job opportunities (as it has in previous decades), the shortcomings of liberal social security systems may depress social and political participation even further than in other capitalist economies.
In general, capitalism as an economic system and mode of production can be summarised by the following:
In free market and laissez-faire forms of capitalism, markets are used most extensively with minimal or no regulation over the pricing mechanism. In mixed economies, which are almost universal today, markets continue to play a dominant role, but they are regulated to some extent by the state in order to correct market failures, promote social welfare, conserve natural resources, fund defense and public safety or other rationale. In state capitalist systems, markets are relied upon the least, with the state relying heavily on state-owned enterprises or indirect economic planning to accumulate capital.
Supply is the amount of a good or service that is available for purchase or sale. Demand is the measure of value for a good that people are willing to buy at a given time. Prices tend to rise when demand for an available resource increases or its supply diminishes and fall with demand or when supply increases.
Competition arises when more than one producer is trying to sell the same or similar products to the same buyers. In capitalist theory, competition leads to innovation and more affordable prices. Without competition, a monopoly or cartel may develop. A monopoly occurs when a firm is granted exclusivity over a market. Hence the firm can engage in rent seeking behaviors such as limiting output and raising prices because it has no fear of competition. A cartel is a group of firms that act together in a monopolistic manner to control output and prices.
Governments have implemented legislation for the purpose of preventing the creation of monopolies and cartels. In 1890, the Sherman Anti-Trust Act became the first legislation passed by the United States Congress to limit monopolies.
The profit motive, in the theory in capitalism, is the desire to earn income in the form of profit. Stated differently, the reason for a business's existence is to turn a profit. The profit motive functions according to rational choice theory, or the theory that individuals tend to pursue what is in their own best interests. Accordingly, businesses seek to benefit themselves and/or their shareholders by maximizing profit.
In capitalist theoretics, the profit motive is said to ensure that resources are being allocated efficiently. For instance, Austrian economist Henry Hazlitt explains: "If there is no profit in making an article, it is a sign that the labor and capital devoted to its production are misdirected: the value of the resources that must be used up in making the article is greater than the value of the article itself". In other words, profits let companies know whether an item is worth producing. Theoretically, in free and competitive markets maximising profit ensures that resources are not wasted.
The relationship between the state, its formal mechanisms and capitalist societies has been debated in many fields of social and political theory, with active discussion since the 19th century. Hernando de Soto is a contemporary Peruvian economist who has argued that an important characteristic of capitalism is the functioning state protection of property rights in a formal property system where ownership and transactions are clearly recorded.
According to de Soto, this is the process by which physical assets are transformed into capital, which in turn may be used in many more ways and much more efficiently in the market economy. A number of Marxian economists have argued that the Enclosure Acts in England and similar legislation elsewhere were an integral part of capitalist primitive accumulation and that specific legal frameworks of private land ownership have been integral to the development of capitalism.
In capitalist economics, market competition is the rivalry among sellers trying to achieve such goals as increasing profits, market share and sales volume by varying the elements of the marketing mix: price, product, distribution and promotion. Merriam-Webster defines competition in business as "the effort of two or more parties acting independently to secure the business of a third party by offering the most favourable terms". It was described by Adam Smith in The Wealth of Nations (1776) and later economists as allocating productive resources to their most highly valued uses and encouraging efficiency. Smith and other classical economists before Antoine Augustine Cournot were referring to price and non-price rivalry among producers to sell their goods on best terms by bidding of buyers, not necessarily to a large number of sellers nor to a market in final equilibrium. Competition is widespread throughout the market process. It is a condition where "buyers tend to compete with other buyers, and sellers tend to compete with other sellers". In offering goods for exchange, buyers competitively bid to purchase specific quantities of specific goods which are available, or might be available if sellers were to choose to offer such goods. Similarly, sellers bid against other sellers in offering goods on the market, competing for the attention and exchange resources of buyers. Competition results from scarcity—there is never enough to satisfy all conceivable human wants—and occurs "when people strive to meet the criteria that are being used to determine who gets what".
Historically, capitalism has an ability to promote economic growth as measured by gross domestic product (GDP), capacity utilization or standard of living. This argument was central, for example, to Adam Smith's advocacy of letting a free market control production and price and allocate resources. Many theorists have noted that this increase in global GDP over time coincides with the emergence of the modern world capitalist system.
Between 1000 and 1820, the world economy grew sixfold, a faster rate than the population growth, so individuals enjoyed, on average, a 50% increase in income. Between 1820 and 1998, world economy grew 50-fold, a much faster rate than the population growth, so individuals enjoyed on average a 9-fold increase in income. Over this period, in Europe, North America and Australasia the economy grew 19-fold per person, even though these regions already had a higher starting level; and in Japan, which was poor in 1820, the increase per person was 31-fold. In the Third World, there was an increase, but only 5-fold per person.
As a mode of production
The capitalist mode of production refers to the systems of organising production and distribution within capitalist societies. Private money-making in various forms (renting, banking, merchant trade, production for profit and so on) preceded the development of the capitalist mode of production as such. The capitalist mode of production proper based on wage-labour and private ownership of the means of production and on industrial technology began to grow rapidly in Western Europe from the Industrial Revolution, later extending to most of the world.
The term capitalist mode of production is defined by private ownership of the means of production, extraction of surplus value by the owning class for the purpose of capital accumulation, wage-based labour and at least as far as commodities are concerned being market-based.
Capitalism in the form of money-making activity has existed in the shape of merchants and money-lenders who acted as intermediaries between consumers and producers engaging in simple commodity production (hence the reference to "merchant capitalism") since the beginnings of civilisation. What is specific about the "capitalist mode of production" is that most of the inputs and outputs of production are supplied through the market (i.e. they are commodities) and essentially all production is in this mode. For example, in flourishing feudalism most or all of the factors of production including labour are owned by the feudal ruling class outright and the products may also be consumed without a market of any kind, it is production for use within the feudal social unit and for limited trade. This has the important consequence that the whole organisation of the production process is reshaped and re-organised to conform with economic rationality as bounded by capitalism, which is expressed in price relationships between inputs and outputs (wages, non-labour factor costs, sales and profits) rather than the larger rational context faced by society overall—that is, the whole process is organised and re-shaped in order to conform to "commercial logic". Essentially, capital accumulation comes to define economic rationality in capitalist production.
A society, region or nation is capitalist if the predominant source of incomes and products being distributed is capitalist activity, but even so this does not yet mean necessarily that the capitalist mode of production is dominant in that society.
Supply and demand
In capitalist economic structures, supply and demand is an economic model of price determination in a market. It concludes that in a competitive market, the unit price for a particular good will vary until it settles at a point where the quantity demanded by consumers (at the current price) will equal the quantity supplied by producers (at the current price), resulting in an economic equilibrium for price and quantity.
Graphical representation of supply and demand
Although it is normal to regard the quantity demanded and the quantity supplied as functions of the price of the goods, the standard graphical representation, usually attributed to Alfred Marshall, has price on the vertical axis and quantity on the horizontal axis, the opposite of the standard convention for the representation of a mathematical function.
Since determinants of supply and demand other than the price of the goods in question are not explicitly represented in the supply-demand diagram, changes in the values of these variables are represented by moving the supply and demand curves (often described as "shifts" in the curves). By contrast, responses to changes in the price of the good are represented as movements along unchanged supply and demand curves.
A supply schedule is a table that shows the relationship between the price of a good and the quantity supplied. Under the assumption of perfect competition, supply is determined by marginal cost. That is: firms will produce additional output while the cost of producing an extra unit of output is less than the price they would receive.
A hike in the cost of raw goods would decrease supply and shifting costs up while a discount would increase supply, shifting costs down and hurting producers as producer surplus decreases.
By its very nature, conceptualising a supply curve requires the firm to be a perfect competitor (i.e. to have no influence over the market price). This is true because each point on the supply curve is the answer to the question "If this firm is faced with this potential price, how much output will it be able to and willing to sell?". If a firm has market power, its decision of how much output to provide to the market influences the market price, therefore the firm is not "faced with" any price and the question becomes less relevant.
Economists distinguish between the supply curve of an individual firm and the market supply curve. The market supply curve is obtained by summing the quantities supplied by all suppliers at each potential price, thus in the graph of the supply curve individual firms' supply curves are added horizontally to obtain the market supply curve.
Economists also distinguish the short-run market supply curve from the long-run market supply curve. In this context, two things are assumed constant by definition of the short run: the availability of one or more fixed inputs (typically physical capital) and the number of firms in the industry. In the long-run, firms can adjust their holdings of physical capital, enabling them to better adjust their quantity supplied at any given price. Furthermore, in the long-run potential competitors can enter or exit the industry in response to market conditions. For both of these reasons, long-run market supply curves are generally flatter than their short-run counterparts.
The determinants of supply are:
A demand schedule, depicted graphically as the demand curve, represents the amount of some goods that buyers are willing and able to purchase at various prices, assuming all determinants of demand other than the price of the good in question, such as income, tastes and preferences, the price of substitute goods and the price of complementary goods, remain the same. According to the law of demand, the demand curve is almost always represented as downward-sloping, meaning that as price decreases, consumers will buy more of the good.
Just like the supply curves reflect marginal cost curves, demand curves are determined by marginal utility curves. Consumers will be willing to buy a given quantity of a good at a given price, if the marginal utility of additional consumption is equal to the opportunity cost determined by the price—that is, the marginal utility of alternative consumption choices. The demand schedule is defined as the willingness and ability of a consumer to purchase a given product in a given frame of time.
While the aforementioned demand curve is generally downward-sloping, there may be rare examples of goods that have upward-sloping demand curves. Two different hypothetical types of goods with upward-sloping demand curves are Giffen goods (an inferior, but staple good) and Veblen goods (goods made more fashionable by a higher price).
By its very nature, conceptualising a demand curve requires that the purchaser be a perfect competitor—that is, that the purchaser has no influence over the market price. This is true because each point on the demand curve is the answer to the question "If this buyer is faced with this potential price, how much of the product will it purchase?". If a buyer has market power, so its decision of how much to buy influences the market price, then the buyer is not "faced with" any price and the question is meaningless.
Like with supply curves, economists distinguish between the demand curve of an individual and the market demand curve. The market demand curve is obtained by summing the quantities demanded by all consumers at each potential price, thus in the graph of the demand curve individuals' demand curves are added horizontally to obtain the market demand curve.
The determinants of demand are:
In the context of supply and demand, economic equilibrium refers to a state where economic forces such as supply and demand are balanced and in the absence of external influences the (equilibrium) values of economic variables will not change. For example, in the standard text-book model of perfect competition equilibrium occurs at the point at which quantity demanded and quantity supplied are equal. Market equilibrium in this case refers to a condition where a market price is established through competition such that the amount of goods or services sought by buyers is equal to the amount of goods or services produced by sellers. This price is often called the competitive price or market clearing price and will tend not to change unless demand or supply changes and the quantity is called "competitive quantity" or market clearing quantity.
Partial equilibrium, as the name suggests, takes into consideration only a part of the market to attain equilibrium.
Jain proposes (attributed to George Stigler): "A partial equilibrium is one which is based on only a restricted range of data, a standard example is price of a single product, the prices of all other products being held fixed during the analysis".
The supply and demand model is a partial equilibrium model of economic equilibrium, where the clearance on the market of some specific goods is obtained independently from prices and quantities in other markets. In other words, the prices of all substitutes and complements as well as income levels of consumers are constant. This makes analysis much simpler than in a general equilibrium model which includes an entire economy.
Here the dynamic process is that prices adjust until supply equals demand. It is a powerfully simple technique that allows one to study equilibrium, efficiency and comparative statics. The stringency of the simplifying assumptions inherent in this approach make the model considerably more tractable, but it may produce results which while seemingly precise do not effectively model real world economic phenomena.
Partial equilibrium analysis examines the effects of policy action in creating equilibrium only in that particular sector or market which is directly affected, ignoring its effect in any other market or industry assuming that they being small will have little impact if any.
Hence this analysis is considered to be useful in constricted markets.
Léon Walras first formalised the idea of a one-period economic equilibrium of the general economic system, but it was French economist Antoine Augustin Cournot and English political economist Alfred Marshall who developed tractable models to analyse an economic system.
Demand and supply relations in a market can be statistically estimated from price, quantity and other data with sufficient information in the model. This can be done with simultaneous-equation methods of estimation in econometrics. Such methods allow solving for the model-relevant "structural coefficients", the estimated algebraic counterparts of the theory. The parameter identification problem is a common issue in "structural estimation". Typically, data on exogenous variables (that is, variables other than price and quantity, both of which are endogenous variables) are needed to perform such an estimation. An alternative to "structural estimation" is reduced-form estimation, which regresses each of the endogenous variables on the respective exogenous variables.
Macroeconomic uses of demand and supply
Demand and supply have also been generalised to explain macroeconomic variables in a market economy, including the quantity of total output and the general price level. The Aggregate Demand–Aggregate Supply model may be the most direct application of supply and demand to macroeconomics, but other macroeconomic models also use supply and demand. Compared to microeconomic uses of demand and supply, different (and more controversial) theoretical considerations apply to such macroeconomic counterparts as aggregate demand and aggregate supply. Demand and supply are also used in macroeconomic theory to relate money supply and money demand to interest rates and to relate labor supply and labor demand to wage rates.
According to Hamid S. Hosseini, the power of supply and demand was understood to some extent by several early Muslim scholars, such as fourteenth-century Mamluk scholar Ibn Taymiyyah, who wrote: "If desire for goods increases while its availability decreases, its price rises. On the other hand, if availability of the good increases and the desire for it decreases, the price comes down".
John Locke's 1691 work Some Considerations on the Consequences of the Lowering of Interest and the Raising of the Value of Money includes an early and clear description of supply and demand and their relationship. In this description, demand is rent: "The price of any commodity rises or falls by the proportion of the number of buyer and sellers" and "that which regulates the price... [of goods] is nothing else but their quantity in proportion to their rent".
The phrase "supply and demand" was first used by James Denham-Steuart in his Inquiry into the Principles of Political Economy, published in 1767. Adam Smith used the phrase in his 1776 book The Wealth of Nations, and David Ricardo titled one chapter of his 1817 work Principles of Political Economy and Taxation "On the Influence of Demand and Supply on Price".
In The Wealth of Nations, Smith generally assumed that the supply price was fixed, but that its "merit" (value) would decrease as its "scarcity" increased, in effect what was later called the law of demand also. In Principles of Political Economy and Taxation, Ricardo more rigorously laid down the idea of the assumptions that were used to build his ideas of supply and demand. Antoine Augustin Cournot first developed a mathematical model of supply and demand in his 1838 Researches into the Mathematical Principles of Wealth, including diagrams.
During the late 19th century, the marginalist school of thought emerged. This field mainly was started by Stanley Jevons, Carl Menger and Léon Walras. The key idea was that the price was set by the most expensive price—that is, the price at the margin. This was a substantial change from Adam Smith's thoughts on determining the supply price.
In his 1870 essay "On the Graphical Representation of Supply and Demand", Fleeming Jenkin in the course of "introduc[ing] the diagrammatic method into the English economic literature" published the first drawing of supply and demand curves therein, including comparative statics from a shift of supply or demand and application to the labor market. The model was further developed and popularized by Alfred Marshall in the 1890 textbook Principles of Economics.
Role of government
In a capitalist system, the government does not prohibit private property or prevent individuals from working where they please. The government does not prevent firms from determining what wages they will pay and what prices they will charge for their products. However, many countries have minimum wage laws and minimum safety standards.
Under some versions of capitalism, the government carries out a number of economic functions, such as issuing money, supervising public utilities and enforcing private contracts. Many countries have competition laws that prohibit monopolies and cartels from forming. Despite anti-monopoly laws, large corporations can form near-monopolies in some industries. Such firms can temporarily drop prices and accept losses to prevent competition from entering the market and then raise them again once the threat of entry is reduced. In many countries, public utilities (e.g. electricity, heating fuel and communications) are able to operate as a monopoly under government regulation due to high economies of scale.
Government agencies regulate the standards of service in many industries, such as airlines and broadcasting as well as financing a wide range of programs. In addition, the government regulates the flow of capital and uses financial tools such as the interest rate to control factors such as inflation and unemployment.
Relationship to political freedom
In his book The Road to Serfdom, Friedrich Hayek asserts that the economic freedom of capitalism is a requisite of political freedom. He argues that the market mechanism is the only way of deciding what to produce and how to distribute the items without using coercion. Milton Friedman, Andrew Brennan and Ronald Reagan also promoted this view. Friedman claimed that centralized economic operations are always accompanied by political repression. In his view, transactions in a market economy are voluntary and that the wide diversity that voluntary activity permits is a fundamental threat to repressive political leaders and greatly diminishes their power to coerce. Some of Friedman's views were shared by John Maynard Keynes, who believed that capitalism is vital for freedom to survive and thrive. Freedom House, an American think tank that conducts international research on, and advocates for, democracy, political freedom and human rights, has argued "there is a high and statistically significant correlation between the level of political freedom as measured by Freedom House and economic freedom as measured by the Wall Street Journal/Heritage Foundation survey".
Types of capitalism
There are many variants of capitalism in existence that differ according to country and region. They vary in their institutional makeup and by their economic policies. The common features among all the different forms of capitalism is that they are based on the production of goods and services for profit, predominantly market-based allocation of resources and they are structured upon the accumulation of capital. The major forms of capitalism are listed hereafter:
Advanced capitalism is the situation that pertains to a society in which the capitalist model has been integrated and developed deeply and extensively for a prolonged period. Various writers identify Antonio Gramsci as an influential early theorist of advanced capitalism, even if he did not use the term himself. In his writings, Gramsci sought to explain how capitalism had adapted to avoid the revolutionary overthrow that had seemed inevitable in the 19th century. At the heart of his explanation was the decline of raw coercion as a tool of class power, replaced by use of civil society institutions to manipulate public ideology in the capitalists' favour.
Jürgen Habermas has been a major contributor to the analysis of advanced-capitalistic societies. Habermas observed four general features that characterise advanced capitalism:
In their critique of capitalism, Marxism and Leninism both emphasise the role of "finance capital" as the determining and ruling-class interest in capitalist society, particularly in the latter stages.
Rudolf Hilferding is credited[by whom?] with first bringing the term "finance capitalism" into prominence through Finance Capital, his 1910 study of the links between German trusts, banks and monopolies—a study subsumed by Vladimir Lenin into Imperialism, the Highest Stage of Capitalism (1917), his analysis of the imperialist relations of the great world powers. Lenin concluded that the banks at that time operated as "the chief nerve centres of the whole capitalist system of national economy". For the Comintern (founded in 1919), the phrase "dictatorship of finance capitalism" became a regular one.
Fernnand Braudel would later point to two earlier periods when finance capitalism had emerged in human history—with the Genoese in the 16th century and with the Dutch in the 17th and 18th centuries—although at those points it developed from commercial capitalism.[need quotation to verify] Giovanni Arrighi extended Braudel's analysis to suggest that a predominance of finance capitalism is a recurring, long-term phenomenon, whenever a previous phase of commercial/industrial capitalist expansion reaches a plateau.
Mercantilism is a nationalist form of early capitalism that came into existence approximately in the late 16th century. It is characterized by the intertwining of national business interests to state-interest and imperialism; and consequently, the state apparatus is utilized to advance national business interests abroad. An example of this is colonists living in America who were only allowed to trade with and purchase goods from their respective mother countries (e.g. Britain, Portugal and France). Mercantilism was driven by the belief that the wealth of a nation is increased through a positive balance of trade with other nations—it corresponds to the phase of capitalist development sometimes called the primitive accumulation of capital.
Free-market economy refers to a capitalist economic system where prices for goods and services are set freely by the forces of supply and demand and are allowed to reach their point of equilibrium without intervention by government policy. It typically entails support for highly competitive markets and private ownership of productive enterprises. Laissez-faire is a more extensive form of free-market economy where the role of the state is limited to protecting property rights, or for plumbline anarcho-capitalists, property rights are protected by private firms and market-generated law.
Social market economy
A social market economy is a nominally free market system where government intervention in price formation is kept to a minimum, but the state provides significant services in the area of social security, unemployment benefits and recognition of labor rights through national collective bargaining arrangements. This model is prominent in Western and Northern European countries as well as Japan, albeit in slightly different configurations. The vast majority of enterprises are privately owned in this economic model.
Rhine capitalism refers to the contemporary model of capitalism and adaptation of the social market model that exists in continental Western Europe today.
State capitalism is a capitalist market economy dominated by state-owned enterprises, where the state enterprises are organized as commercial, profit-seeking businesses. The designation has been used broadly throughout the 20th century to designate a number of different economic forms, ranging from state-ownership in market economies to the command economies of the former Eastern Bloc. According to Aldo Musacchio, a professor at Harvard Business School, state capitalism is a system in which governments, whether democratic or autocratic, exercise a widespread influence on the economy either through direct ownership or various subsidies. Musacchio notes a number of differences between today's state capitalism and its predecessors. In his opinion, gone are the days when governments appointed bureaucrats to run companies: the world's largest state-owned enterprises are now traded on the public markets and kept in good health by large institutional investors. Contemporary state capitalism is associated with the East Asian model of capitalism, dirigisme and the economy of Norway. Alternatively, Merriam-Webster defines state capitalism as "an economic system in which private capitalism is modified by a varying degree of government ownership and control".
In Socialism: Utopian and Scientific, Friedrich Engels argued that state-owned enterprises would characterize the final stage of capitalism, consisting of ownership and management of large-scale production and communication by the bourgeois state. In his writings, Vladimir Lenin characterized the economy of Soviet Russia as state capitalist, believing state capitalism to be an early step toward the development of socialism.
Some economists and left-wing academics including Richard D. Wolff and Noam Chomsky argue that the economies of the former Soviet Union and Eastern bloc represented a form of state capitalism because their internal organization within enterprises and the system of wage labor remained intact.
The term is not used by Austrian School economists to describe state ownership of the means of production. The economist Ludwig von Mises argued that the designation of "state capitalism" was simply a new label for the old labels of "state socialism" and "planned economy" and differed only in non-essentials from these earlier designations.
The debate between proponents of private versus state capitalism is centered around questions of managerial efficacy, productive efficiency and fair distribution of wealth.
Corporate capitalism is a free or mixed-market economy characterized by the dominance of hierarchical, bureaucratic corporations.
A mixed economy is a largely market-based economy consisting of both private and public ownership of the means of production and economic interventionism through macroeconomic policies intended to correct market failures, reduce unemployment and keep inflation low. The degree of intervention in markets varies among different countries. Some mixed economies, such as France under dirigisme, also featured a degree of indirect economic planning over a largely capitalist-based economy.
Most modern capitalist economies are defined as "mixed economies" to some degree.
Other variants of capitalism include:
The accumulation of capital is the process of "making money", or growing an initial sum of money through investment in production. Capitalism is based on the accumulation of capital, whereby financial capital is invested in order to make a profit and then reinvested into further production in a continuous process of accumulation. In Marxian economic theory, this dynamic is called the law of value. Capital accumulation forms the basis of capitalism, where economic activity is structured around the accumulation of capital, defined as investment in order to realize a financial profit. In this context, "capital" is defined as money or a financial asset invested for the purpose of making more money (whether in the form of profit, rent, interest, royalties, capital gain or some other kind of return).
In mainstream economics, accounting and Marxian economics, capital accumulation is often equated with investment of profit income or saving, especially in real capital goods. The concentration and centralisation of capital are two of the results of such accumulation. In modern macroeconomics and econometrics, the phrase "capital formation" is often used in preference to "accumulation", though the United Nations Conference on Trade and Development (UNCTAD) refers nowadays to "accumulation". The term “accumulation” is occasionally used in national accounts.
Accumulation can be measured as the monetary value of investments, the amount of income that is reinvested, or as the change in the value of assets owned (the increase in the value of the capital stock). Using company balance sheets, tax data and direct surveys as a basis, government statisticians estimate total investments and assets for the purpose of national accounts, national balance of payments and flow of funds statistics. The Reserve Banks and the Treasury usually provide interpretations and analysis of this data. Standard indicators include capital formation, gross fixed capital formation, fixed capital, household asset wealth and foreign direct investment.
Organisations such as the International Monetary Fund, the UNCTAD, the World Bank Group, the OECD and the Bank for International Settlements used national investment data to estimate world trends. The Bureau of Economic Analysis, Eurostat and the Japan Statistical Office provide data on the United States, Europe and Japan respectively. Other useful sources of investment information are business magazines such as Fortune, Forbes, The Economist, Business Week and so on as well as various corporate "watchdog" organisations and non-governmental organisation publications. A reputable scientific journal is the Review of Income & Wealth. In the case of the United States, the "Analytical Perspectives" document (an annex to the yearly budget) provides useful wealth and capital estimates applying to the whole country.
In Karl Marx' economic theory, capital accumulation refers to the operation whereby profits are reinvested increasing the total quantity of capital. Capital is viewed by Marx as expanding value, that is, in other terms, as a sum of capital, usually expressed in money, that is transformed through human labor into a larger value, extracted as profits and expressed as money. Here, capital is defined essentially as economic or commercial asset value in search of additional value or surplus-value. This requires property relations which enable objects of value to be appropriated and owned, and trading rights to be established. Capital accumulation has a double origin, namely in trade and in expropriation, both of a legal or illegal kind. The reason is that a stock of capital can be increased through a process of exchange or "trading up", but also through directly taking an asset or resource from someone else without compensation. David Harvey calls this accumulation by dispossession.
The continuation and progress of capital accumulation depends on the removal of obstacles to the expansion of trade and this has historically often been a violent process. As markets expand, more and more new opportunities develop for accumulating capital because more and more types of goods and services can be traded in. However, capital accumulation may also confront resistance when people refuse to sell, or refuse to buy (for example a strike by investors or workers, or consumer resistance).
Concentration and centralisation
According to Marx, capital has the tendency for concentration and centralization in the hands of the wealthy. Marx explains: "It is concentration of capitals already formed, destruction of their individual independence, expropriation of capitalist by capitalist, transformation of many small into few large capitals. [...] Capital grows in one place to a huge mass in a single hand, because it has in another place been lost by many. [...] The battle of competition is fought by cheapening of commodities. The cheapness of commodities demands, caeteris paribus, on the productiveness of labour, and this again on the scale of production. Therefore, the larger capitals beat the smaller. It will further be remembered that, with the development of the capitalist mode of production, there is an increase in the minimum amount of individual capital necessary to carry on a business under its normal conditions. The smaller capitals, therefore, crowd into spheres of production which Modern Industry has only sporadically or incompletely got hold of. Here competition rages [...] It always ends in the ruin of many small capitalists, whose capitals partly pass into the hands of their conquerors, partly vanish".
Rate of accumulation
In Marxian economics, the rate of accumulation is defined as (1) the value of the real net increase in the stock of capital in an accounting period; and (2) the proportion of realised surplus-value or profit-income which is reinvested, rather than consumed. This rate can be expressed by means of various ratios between the original capital outlay, the realised turnover, surplus-value or profit and reinvestments (e.g. the writings of the economist Michał Kalecki).
Other things being equal, the greater the amount of profit-income that is disbursed as personal earnings and used for consumptive purposes, the lower the savings rate and the lower the rate of accumulation is likely to be. However, earnings spent on consumption can also stimulate market demand and higher investment. This is the cause of endless controversies in economic theory about "how much to spend, and how much to save".
In a boom period of capitalism, the growth of investments is cumulative, i.e. one investment leads to another, leading to a constantly expanding market, an expanding labor force and an increase in the standard of living for the majority of the people.
In a stagnating, decadent capitalism, the accumulation process is increasingly oriented towards investment on military and security forces, real estate, financial speculation and luxury consumption. In that case, income from value-adding production will decline in favour of interest, rent and tax income, with as a corollary an increase in the level of permanent unemployment. The more capital one owns, the more capital one can also borrow. The inverse is also true and this is one factor in the widening gap between the rich and the poor.
Ernest Mandel emphasised that the rhythm of capital accumulation and growth depended critically on (1) the division of a society's social product between "necessary product" and "surplus product"; and (2) the division of the surplus product between investment and consumption. In turn, this allocation pattern reflected the outcome of competition among capitalists, competition between capitalists and workers and competition between workers. The pattern of capital accumulation can therefore never be simply explained by commercial factors as it also involved social factors and power relationships.
Circuit of capital accumulation from production
Strictly speaking, capital has accumulated only when realised profit income has been reinvested in capital assets. As suggested in the first volume of Marx' Das Kapital, the process of capital accumulation in production has at least seven distinct but linked moments:
All of these moments do not refer simply to an "economic" or commercial process. Rather, they assume the existence of legal, social, cultural and economic power conditions, without which creation, distribution and circulation of the new wealth could not occur. This becomes especially clear when the attempt is made to create a market where none exists, or where people refuse to trade.
Simple and expanded reproduction
In the second volume of Das Kapital, Marx continues the story and shows that with the aid of bank credit capital in search of growth can more or less smoothly mutate from one form to another, alternately taking the form of money capital (liquid deposits, securities and so on), commodity capital (tradable products, real estate and the like), or production capital (means of production and labor power).
His discussion of the simple and expanded reproduction of the conditions of production offers a more sophisticated model of the parameters of the accumulation process as a whole. At simple reproduction, a sufficient amount is produced to sustain society at the given living standard; the stock of capital stays constant. At expanded reproduction, more product-value is produced than is necessary to sustain society at a given living standard (a surplus product); the additional product-value is available for investments which enlarge the scale and variety of production.
The bourgeois claim there is no economic law according to which capital is necessarily re-invested in the expansion of production, that such depends on anticipated profitability, market expectations and perceptions of investment risk. Such statements only explain the subjective experiences of investors and ignore the objective realities which would influence such opinions. As Marx states in the second volume of Das Kapital, simple reproduction only exists if the variable and surplus capital realised by Dept. 1—producers of means of production—exactly equals that of the constant capital of Dept. 2, producers of articles of consumption (p. 524). Such equilibrium rests on various assumptions, such as a constant labor supply (no population growth). Accumulation does not imply a necessary change in total magnitude of value produced, but can simply refer to a change in the composition of an industry (p. 514).
Ernest Mandel introduced the additional concept of contracted economic reproduction, i.e. reduced accumulation where business operating at a loss outnumbers growing business, or economic reproduction on a decreasing scale, for example due to wars, natural disasters or devalorisation.
Balanced economic growth requires that different factors in the accumulation process expand in appropriate proportions. However, markets themselves cannot spontaneously create that balance and in fact what drives business activity is precisely the imbalances between supply and demand: inequality is the motor of growth. This partly explains why the worldwide pattern of economic growth is very uneven and unequal, even although markets have existed almost everywhere for a very long-time. Some people argue that it also explains government regulation of market trade and protectionism.
"Accumulation of capital" sometimes also refers in Marxist writings to the reproduction of capitalist social relations (institutions) on a larger scale over time, i.e. the expansion of the size of the proletariat and of the wealth owned by the bourgeoisie.
This interpretation emphasises that capital ownership, predicated on command over labor, is a social relation: the growth of capital implies the growth of the working class (a "law of accumulation"). In the first volume of Das Kapital, Marx had illustrated this idea with reference to Edward Gibbon Wakefield's theory of colonisation:
In the third volume of Das Kapital, Marx refers to the "fetishism of capital" reaching its highest point with interest-bearing capital because now capital seems to grow of its own accord without anybody doing anything:
Wage labour refers to the sale of labour under a formal or informal employment contract to an employer. These transactions usually occur in a labour market where wages are market determined. Individuals who possess and supply financial capital or labor to productive ventures often become owners, either jointly (as shareholders) or individually. In Marxist economics, these owners of the means of production and suppliers of capital are generally called capitalists. The description of the role of the capitalist has shifted, first referring to a useless intermediary between producers to an employer of producers and eventually came to refer to owners of the means of production. Labor includes all physical and mental human resources, including entrepreneurial capacity and management skills, which are needed to produce products and services. Production is the act of making goods or services by applying labor power.
Critics of the capitalist mode of production see wage labour as a major, if not defining, aspect of hierarchical industrial systems. Most opponents of the institution support worker self-management and economic democracy as alternatives to both wage labour and to capitalism. While most opponents of the wage system blame the capitalist owners of the means of production for its existence, most anarchists and other libertarian socialists also hold the state as equally responsible as it exists as a tool utilised by capitalists to subsidise themselves and protect the institution of private ownership of the means of production. As some opponents of wage labour take influence from Marxist propositions, many are opposed to private property, but maintain respect for personal property.
The most common form of wage labour currently is ordinary direct, or "full-time", employment in which a free worker sells his or her labour for an indeterminate time (from a few years to the entire career of the worker) in return for a money-wage or salary and a continuing relationship with the employer which it does not in general offer contractors or other irregular staff. However, wage labour takes many other forms and explicit as opposed to implicit (i.e. conditioned by local labour and tax law) contracts are not uncommon. Economic history shows a great variety of ways in which labour is traded and exchanged. The differences show up in the form of:
Effects of war
War typically causes the diversion, destruction and creation of capital assets as capital assets are both destroyed or consumed and diverted to types of production needed to fight the war. Many assets are wasted and in some few cases created specifically to fight a war. War driven demands may be a powerful stimulus for the accumulation of capital and production capability in limited areas and market expansion outside the immediate theatre of war. Often this has induced laws against perceived and real war profiteering.
The total hours worked in the United States rose by 34 percent during World War II, even though the military draft reduced the civilian labor force by 11 percent.
War destruction can be illustrated by looking at World War II. Industrial war damage was heaviest in Japan, where 1/4 of factory buildings and 1/3 of plant and equipment were destroyed; 1/7 of electric power-generating capacity was destroyed and 6/7 of oil refining capacity. The Japanese merchant fleet lost 80% of their ships. In Germany in 1944, when air attacks were heaviest, 6.5% of machine tools were damaged or destroyed, but around 90% were later repaired. About 10% of steel production capacity was lost. In Europe, the United States and the Soviet Union enormous resources were accumulated and ultimately dissipated as planes, ships, tanks and so on were built and then lost or destroyed.
Germany's total war damage was estimated at about 17.5% of the pre-war total capital stock by value, i.e. about 1/6. In the Berlin area alone, there were 8 million refugees lacking basic necessities. In 1945, less than 10% of the railways were still operating. 2,395 rail bridges were destroyed and a total of 7,500 bridges, 10,000 locomotives and more than 100,000 goods wagons were destroyed. Less than 40% of the remaining locomotives were operational.
However, by the first quarter of 1946 European rail traffic, which was given assistance and preferences (by Western appointed military governors) for resources and material as an essential asset, regained its prewar operational level. At the end of the year, 90% of Germany's railway lines were operating again. In retrospect, the rapidity of infrastructure reconstruction appears astonishing.
Initially, in May 1945 newly installed United States president Harry S. Truman's directive had been that no steps would be taken towards economic rehabilitation of Germany. In fact, the initial industry plan of 1946 prohibited production in excess of half of the 1938 level; the iron and steel industry was allowed to produce only less than a third of pre-war output. These plans were rapidly revised and better plans were instituted. In 1946, over 10% of Germany's physical capital stock (plant and equipment) was also dismantled and confiscated, most of it going to the Soviet Union. By 1947, industrial production in Germany was at 1/3 of the 1938 level and industrial investment at about 1/2 the 1938 level.
The first big strike-wave in the Ruhr occurred in early 1947—it was about food rations and housing, but soon there were demands for nationalisation. However, the United States appointed military governor (Newman) stated at the time that he had the power to break strikes by withholding food rations. The clear message was "no work, no eat". As the military controls in Western Germany were nearly all relinquished and the Germans were allowed to rebuild their own economy with Marshall Plan aid things rapidly improved. By 1951, German industrial production had overtaken the prewar level. The Marshall Aid funds were important, but after the currency reform (which permitted German capitalists to revalue their assets) and the establishment of a new political system much more important was the commitment of the United States to rebuilding German capitalism and establishing a free market economy and government, rather than keeping Germany in a weak position. Initially, average real wages remained low, lower even than in 1938, until the early 1950s while profitability was unusually high. So the total investment fund, aided by credits, was also high, resulting in a high rate of capital accumulation which was nearly all reinvested in new construction or new tools. This was called the German economic miracle or Wirtschaftswunder.
In Italy, the victorious Allies did three things in 1945: they imposed their absolute military authority; they quickly disarmed the Italian partisans from a very large stock of weapons; and they agreed to a state guarantee of wage payments as well as a veto on all sackings of workers from their jobs. Although the Italian Communist Party grew very large immediately after the war ended—it achieved a membership of 1.7 million people in a population of 45 million—it was outmaneuvered through a complicated political battle by the Christian Democrats after three years. In the 1950s, an economic boom began in Italy, at first fueled by internal demand and then also by exports.
In modern times, it has often been possible to rebuild physical capital assets destroyed in wars completely within the space of about 10 years, except in cases of severe pollution by chemical warfare or other kinds of irreparable devastation. However, damage to human capital has been much more devastating in terms of fatalities (in the case of World War II, about 55 million deaths), permanent physical disability, enduring ethnic hostility and psychological injuries which have effects for at least several generations.
Critics of capitalism associate the economic system with social inequality; unfair distribution of wealth and power; materialism; repression of workers and trade unionists; social alienation; economic inequality; unemployment; and economic instability. Many socialists consider capitalism to be irrational in that production and the direction of the economy are unplanned, creating many inconsistencies and internal contradictions. Capitalism and individual property rights have been associated with the tragedy of the anticommons where owners are unable to agree. Marxian economist Richard D. Wolff postulates that capitalist economies prioritize profits and capital accumulation over the social needs of communities and capitalist enterprises rarely include the workers in the basic decisions of the enterprise. Democratic socialists argue that the role of the state in a capitalist society is to defend the interests of the bourgeoisie. These states take actions to implement such things as unified national markets, national currencies and customs system. Capitalism and capitalist governments have also been criticized as oligarchic in nature due to the inevitable inequality characteristic of economic progress.
Some labor historians and scholars have argued that unfree labor—by slaves, indentured servants, prisoners or other coerced persons—is compatible with capitalist relations. Tom Brass argued that unfree labor is acceptable to capital. Historian Greg Grandin argues that capitalism has its origins in slavery, saying that "[w]hen historians talk about the Atlantic market revolution, they are talking about capitalism. And when they are talking about capitalism, they are talking about slavery." Some historians, including Edward E. Baptist and Sven Beckert, assert that slavery was an integral component in the violent development of American and global capitalism. The Slovenian continental philosopher Slavoj Žižek posits that the new era of global capitalism has ushered in new forms of contemporary slavery, including migrant workers deprived of basic civil rights on the Arabian Peninsula, the total control of workers in Asian sweatshops, and the use of forced labor in the exploitation of natural resources in Central Africa.
According to Immanuel Wallerstein, institutional racism has been "one of the most significant pillars" of the capitalist system and serves as "the ideological justification for the hierarchization of the work-force and its highly unequal distributions of reward".
Many aspects of capitalism have come under attack from the anti-globalization movement, which is primarily opposed to corporate capitalism. Environmentalists have argued that capitalism requires continual economic growth and that it will inevitably deplete the finite natural resources of Earth and cause mass extinctions of animal and plant life. Such critics argue that while neoliberalism, the ideological backbone of contemporary globalized capitalism, has indeed increased global trade, it has also destroyed traditional ways of life, exacerbated inequality, increased global poverty, and that environmental indicators indicate massive environmental degradation since the late 1970s.
Some scholars blame the financial crisis of 2007–2008 on the neoliberal capitalist model. Following the banking crisis of 2007, Alan Greenspan told the United States Congress on 23 October 2008 that "[t]his modern risk-management paradigm held sway for decades. The whole intellectual edifice, however, collapsed in the summer of last year", and that "I made a mistake in presuming that the self-interests of organizations, specifically banks and others, were such that they were best capable of protecting their own shareholders and their equity in firms [...] I was shocked".
Many religions have criticized or opposed specific elements of capitalism. Traditional Judaism, Christianity, and Islam forbid lending money at interest, although alternative methods of banking have been developed. Some Christians have criticized capitalism for its materialist aspects and its inability to account for the wellbeing of all people. Many of Jesus' parables deal with economic concerns: farming, shepherding, being in debt, doing hard labor, being excluded from banquets and the houses of the rich and have implications for wealth and power distribution. Catholic scholars and clergy have often criticized capitalism because of its disenfranchisement of the poor, often promoting distributism as an alternative. In his 84-page apostolic exhortation Evangelii gaudium, Catholic Pope Francis described unfettered capitalism as "a new tyranny" and called on world leaders to fight rising poverty and inequality:
Proponents of capitalism argue that it creates more prosperity than any other economic system and that its benefits are mainly to the ordinary person. Critics of capitalism variously associate it with economic instability, an inability to provide for the well-being of all people and an unsustainable danger to the natural environment. Socialists maintain that although capitalism is superior to all previously existing economic systems (such as feudalism or slavery), the contradiction between class interests will only be resolved by advancing into a completely new social system of production and distribution in which all persons have an equal relationship to the means of production.
The term capitalism in its modern sense is often attributed to Karl Marx. In his Das Kapital, Marx analyzed the "capitalist mode of production" using a method of understanding today known as Marxism. However, Marx himself rarely used the term "capitalism" while it was used twice in the more political interpretations of his work, primarily authored by his collaborator Friedrich Engels. In the 20th century, defenders of the capitalist system often replaced the term capitalism with phrases such as free enterprise and private enterprise and replaced capitalist with rentier and investor in reaction to the negative connotations associated with capitalism.
The majority of criticisms against the profit motive centre on the idea that the profit motive encourages selfishness and greed, rather than serve the public good or necessarily creating an increase in net wealth. Critics of the profit motive contend that companies disregard morals or public safety in the pursuit of profits.
Free market economists counter that the profit motive, coupled with competition, actually reduces the final price of an item for consumption, rather than raising it. They argue that businesses profit by selling a good at a lower price and at a greater volume than the competition. Economist Thomas Sowell uses supermarkets as an example to illustrate this point: "It has been estimated that a supermarket makes a clear profit of about a penny on a dollar of sales. If that sounds pretty skimpy, remember that it is collecting that penny on every dollar at several cash registers simultaneously and, in many cases, around the clock".
American economist Milton Friedman has argued that greed and self-interest are universal human traits. On a 1979 episode of The Phil Donahue Show, Friedman states: "The world runs on individuals pursuing their separate interests". He continues by explaining that only in capitalist countries, where individuals can pursue their own self-interest, people have been able to escape from "grinding poverty".
Comparison to slavery
Wage labor has long been compared to slavery. As a result, the phrase "wage slavery" is often utilized as a pejorative for wage labor. Similarly, advocates of slavery looked upon the "comparative evils of Slave Society and of Free Society, of slavery to human Masters and slavery to Capital" and proceeded to argue that wage slavery was actually worse than chattel slavery. Slavery apologists like George Fitzhugh contended that workers only accepted wage labor with the passage of time as they became "familiarised and inattentive to the infected social atmosphere they continually inhale". Scholars have debated the exact relationship between wage labor, slavery, and capitalism at length, especially for the Antebellum South.
Similarities between wage labor and slavery were noted as early as Cicero in Ancient Rome, such as in De Officiis. With the advent of the Industrial Revolution, thinkers such as Pierre-Joseph Proudhon and Karl Marx elaborated the comparison between wage labor and slavery in the context of a critique of societal property not intended for active personal use while Luddites emphasized the dehumanisation brought about by machines. Before the American Civil War, Southern defenders of African American slavery invoked the concept of wage slavery to favorably compare the condition of their slaves to workers in the North. The United States abolished slavery during the Civil War, but labor union activists found the metaphor useful. According to Lawrence Glickman, in the Gilded Age "references abounded in the labor press, and it is hard to find a speech by a labour leader without the phrase".
The slave, together with his labour-power, was sold to his owner once for all. [...] The [wage] labourer, on the other hand, sells his very self, and that by fractions. [...] He [belongs] to the capitalist class; and it is for him [...] to find a buyer in this capitalist class.
According to Noam Chomsky, analysis of the psychological implications of wage slavery goes back to the Enlightenment era. In his 1791 book On the Limits of State Action, liberal thinker Wilhelm von Humboldt explained how "whatever does not spring from a man's free choice, or is only the result of instruction and guidance, does not enter into his very nature; he does not perform it with truly human energies, but merely with mechanical exactness" and so when the laborer works under external control, "we may admire what he does, but we despise what he is". Both the Milgram and Stanford experiments have been found useful in the psychological study of wage-based workplace relations. Additionally, as per anthropologist David Graeber, the earliest wage labor contracts we know about were in fact contracts for the rental of chattel slaves (usually the owner would receive a share of the money and the slave another, with which to maintain his or her living expenses). According to Graeber, such arrangements were quite common in New World slavery as well, whether in the United States or Brazil. C. L. R. James argued in The Black Jacobins that most of the techniques of human organisation employed on factory workers during the Industrial Revolution were first developed on slave plantations.
Some anti-capitalist thinkers claim that the elite maintain wage slavery and a divided working class through their influence over the media and entertainment industry, educational institutions, unjust laws, nationalist and corporate propaganda, pressures and incentives to internalize values serviceable to the power structure, state violence, fear of unemployment and a historical legacy of exploitation and profit accumulation/transfer under prior systems, which shaped the development of economic theory:
Aristotle made the statement that "the citizens must not live a mechanic or a mercantile life (for such a life is ignoble and inimical to virtue), nor yet must those who are to be citizens in the best state be tillers of the soil (for leisure is needed both for the development of virtue and for active participation in politics)", often paraphrased as "all paid jobs absorb and degrade the mind". Cicero wrote in 44 BC that "vulgar are the means of livelihood of all hired workmen whom we pay for mere manual labour, not for artistic skill; for in their case the very wage they receive is a pledge of their slavery". Somewhat similar criticisms have also been expressed by some proponents of liberalism, like Henry George, Silvio Gesell and Thomas Paine as well as the Distributist school of thought within the Roman Catholic Church.
To Marxist and anarchist thinkers like Mikhail Bakunin and Peter Kropotkin, wage slavery was a class condition in place due to the existence of private property and the state. This class situation rested primarily on:
For Marxists, labor as commodity, which is how they regard wage labor, provides a fundamental point of attack against capitalism. "It can be persuasively argued", noted one concerned philosopher, "that the conception of the worker's labour as a commodity confirms Marx's stigmatization of the wage system of private capitalism as 'wage-slavery;' that is, as an instrument of the capitalist's for reducing the worker's condition to that of a slave, if not below it". That this objection is fundamental follows immediately from Marx's conclusion that wage labor is the very foundation of capitalism: "Without a class dependent on wages, the moment individuals confront each other as free persons, there can be no production of surplus value; without the production of surplus-value there can be no capitalist production, and hence no capital and no capitalist!".
Marx considered capitalism to be a historically specific mode of production (the way in which the productive property is owned and controlled, combined with the corresponding social relations between individuals based on their connection with the process of production).
The "capitalistic era" according to Karl Marx dates from 16th-century merchants and small urban workshops. Marx knew that wage labour existed on a modest scale for centuries before capitalist industry. For Marx, the capitalist stage of development or "bourgeois society" represented the most advanced form of social organization to date, but he also thought that the working classes would come to power in a worldwide socialist or communist transformation of human society as the end of the series of first aristocratic, then capitalist and finally working class rule was reached.
Following Adam Smith, Marx distinguished the use value of commodities from their exchange value in the market. According to Marx, capital is created with the purchase of commodities for the purpose of creating new commodities with an exchange value higher than the sum of the original purchases. For Marx, the use of labor power had itself become a commodity under capitalism and the exchange value of labor power, as reflected in the wage, is less than the value it produces for the capitalist.
This difference in values, he argues, constitutes surplus value, which the capitalists extract and accumulate. In his book Capital, Marx argues that the capitalist mode of production is distinguished by how the owners of capital extract this surplus from workers—all prior class societies had extracted surplus labor, but capitalism was new in doing so via the sale-value of produced commodities. He argues that a core requirement of a capitalist society is that a large portion of the population must not possess sources of self-sustenance that would allow them to be independent and are instead forced to sell their labor for a wage.
In conjunction with his criticism of capitalism was Marx's belief that the working class, due to its relationship to the means of production and numerical superiority under capitalism, would be the driving force behind the socialist revolution. This argument is intertwined with Marx' version of the labor theory of value arguing that labor is the source of all value and thus of profit.
In Imperialism, the Highest Stage of Capitalism (1916), Vladimir Lenin further developed Marxist theory and argued that capitalism necessarily led to monopoly capitalism and the export of capital—which he also called "imperialism"—to find new markets and resources, representing the last and highest stage of capitalism. Some 20th century Marxian economists consider capitalism to be a social formation where capitalist class processes dominate, but are not exclusive.
To these thinkers, capitalist class processes are simply those in which surplus labor takes the form of surplus value, usable as capital; other tendencies for utilization of labor nonetheless exist simultaneously in existing societies where capitalist processes predominate. However, other late Marxian thinkers argue that a social formation as a whole may be classed as capitalist if capitalism is the mode by which a surplus is extracted, even if this surplus is not produced by capitalist activity as when an absolute majority of the population is engaged in non-capitalist economic activity.
In Limits to Capital (1982), David Harvey outlines an overdetermined, "spatially restless" capitalism coupled with the spatiality of crisis formation and resolution. Harvey used Marx's theory of crisis to aid his argument that capitalism must have its "fixes", but that we cannot predetermine what fixes will be implemented, nor in what form they will be. His work on contractions of capital accumulation and international movements of capitalist modes of production and money flows has been influential. According to Harvey, capitalism creates the conditions for volatile and geographically uneven development 
Sociologists such as Ulrich Beck envisioned the society of risk as a new cultural value which saw risk as a commodity to be exchanged in globalized economies. This theory suggested that disasters and capitalist economy were inevitably entwined. Disasters allow the introduction of economic programs which otherwise would be rejected as well as decentralizing the class structure in production.
Criticism on the environmental sustainability of capitalism
Scholars argue that the capitalist approach to environmental economics does not take into consideration the preserving of natural resources. Capitalism creates three ecological problems: growth, technology, and consumption. The growth problem results from the nature of capitalism, as it focuses around the accumulation of Capital. The innovation of new technologies has an impact on the environmental future as they serve as a capitalist tool in which environmental technologies can result in the expansion of the system. Consumption is focused around the capital accumulation of commodities and neglects the use-value of production.
Supply and demand
At least two assumptions are necessary for the validity of the standard model: first, that supply and demand are independent; and second, that supply is "constrained by a fixed resource". If these conditions do not hold, then the Marshallian model cannot be sustained. Sraffa's critique focused on the inconsistency (except in implausible circumstances) of partial equilibrium analysis and the rationale for the upward slope of the supply curve in a market for a produced consumption good. The notability of Sraffa's critique is also demonstrated by Paul A. Samuelson's comments and engagements with it over many years, for example:
Aggregate excess demand in a market is the difference between the quantity demanded and the quantity supplied as a function of price. In the model with an upward-sloping supply curve and downward-sloping demand curve, the aggregate excess demand function only intersects the axis at one point, namely at the point where the supply and demand curves intersect. The Sonnenschein–Mantel–Debreu theorem shows that the standard model cannot be rigorously derived in general from general equilibrium theory.
The model of prices being determined by supply and demand assumes perfect competition. However, "economists have no adequate model of how individuals and firms adjust prices in a competitive model. If all participants are price-takers by definition, then the actor who adjusts prices to eliminate excess demand is not specified". Goodwin, Nelson, Ackerman and Weisskopf write:
Market failure occurs when an externality is present and a market will often either under-produce a product with a positive externalisation or overproduce a product that generates a negative externalisation. Air pollution, for instance, is a negative externalisation that cannot be easily incorporated into markets as the world's air is not owned and then sold for use to polluters. So too much pollution could be emitted and people not involved in the production pay the cost of the pollution instead of the firm that initially emitted the air pollution. Critics of market failure theory, like Ronald Coase, Harold Demsetz and James M. Buchanan, argue that government programs and policies also fall short of absolute perfection. While all nations currently have some kind of market regulations, the desirable degree of regulation is disputed.
Austrian School economists have argued that capitalism can organize itself into a complex system without an external guidance or central planning mechanism. Friedrich Hayek considered the phenomenon of self-organisation as underpinning capitalism. Prices serve as a signal as to the urgent and unfilled wants of people and the opportunity to earn profits if successful, or absorb losses if resources are used poorly or left idle, gives entrepreneurs incentive to use their knowledge and resources to satisfy those wants. Thus the activities of millions of people, each seeking his own interest, are coordinated.
The novelist and philosopher Ayn Rand made positive moral defenses of laissez-faire capitalism, most notably in her 1957 novel Atlas Shrugged and in her 1966 collection of essays Capitalism: The Unknown Ideal. She argued that capitalism should be supported on moral grounds, not just on the basis of practical benefits. Her ideas have had significant influence over conservative and libertarian supporters of capitalism, especially within the American Tea Party movement. Rand defined capitalism as "a social system based on the recognition of individual rights, including property rights, in which all property is privately owned". According to Rand, the role of government in a capitalist state has three broad categories of proper functions: first, the police "to protect men from criminals"; second, the armed services "to protect men from foreign invaders"; and third, the law courts "to settle disputes among men according to objective laws".
