Economics (/ˌɛkəˈnɒmɪks, ˌiːkə-/) is a social science that studies the production, distribution, and consumption of goods and services.
Economics focuses on the behaviour and interactions of economic agents and how economies work. Microeconomics analyses what is viewed as the basic elements of economies, including individual agents and markets, their interactions, and the outcomes of those interactions. Individual agents may include households, firms, buyers, and sellers. Macroeconomics analyses economies as systems where production, distribution, consumption, savings, and investment expenditure interact; and the factors of production affecting them, such as: labour, capital, land, and enterprise, inflation, economic growth, and public policies that impact these elements. It also seeks to analyse and describe the global economy. (Full article...)
Selected general articles
In the history of economic thought, ancient economic thought refers to the ideas from people before the Middle Ages.
Economics in the classical age is defined in the modern analysis as a factor of ethics and politics, only becoming an object of study as a separate discipline during the 18th century. (Full article...)
Johann Silvio Gesell (German: [ɡəˈzɛl]; 17 March 1862 – 11 March 1930) was a German-Argentine economist, entrepreneur, and social reformer. He was the founder of Freiwirtschaft (German for "free economy"), an economic model for market socialism. In 1900, he founded the magazine Money and Land Reform (German: Die Geld- und Bodenreform), but it soon closed for financial reasons. During his time in Oranienburg, Gesell started the magazine Der Physiokrat together with George Heinrich Blumenthal. In 1914, it closed due to censorship. In 1916, he published his most famous work, The Natural Economic Order.
Gesell is mainly known for his monetary theory. In particular, he noted the asymmetry between the durability and hoardability of money and the finite shelf life of goods and services which depreciate due to entropy and the passage of time. He believed that people who are able to save or hoard money have an unfair economic advantage over people who are dependent on producing and selling decayable goods and services for their livelihoods. Gesell theorized that the unfair premium enjoyed by hoarders expressed itself in interest rates and spawned recessions, an argument that later influenced John Maynard Keynes's theory of liquidity preference. To resolve this problem, Gesell proposed a new form of money that depreciates over time (German: Freigeld). (Full article...)
Thomas Robert Malthus, after whom Malthusianism is named
Malthusianism is a theory that population growth is potentially exponential, according to the Malthusian growth model, while the growth of the food supply or other resources is linear, which eventually reduces living standards to the point of triggering a population decline. This event, called a Malthusian catastrophe (also known as a Malthusian trap, population trap, Malthusian check, Malthusian snatch, Malthusian crisis, point of crisis, or Malthusian crunch) has been predicted to occur if population growth outpaces agricultural production, thereby causing famine or war. According to this theory, poverty and inequality will increase as the price of assets and scarce commodities goes up due to fierce competition for these dwindling resources. This increased level of poverty eventually causes depopulation by decreasing birth rates. If asset prices keep increasing, social unrest would occur, which would likely cause a major war, revolution, or a famine. Societal collapse is an extreme but possible outcome from this process. The theory posits that such a catastrophe would force the population to "correct" back to a lower, more easily sustainable level (quite rapidly, due to the potential severity and unpredictable results of the mitigating factors involved, as compared to the relatively slow time scales and well-understood processes governing unchecked growth or growth affected by preventive checks). Malthusianism has been linked to a variety of political and social movements, but almost always refers to advocates of population control.
These concepts derive from the political and economic thought of the Reverend Thomas Robert Malthus, as laid out in his 1798 writings, An Essay on the Principle of Population. Malthus suggested that while technological advances could increase a society's supply of resources, such as food, and thereby improve the standard of living, the abundance of resources would enable population growth, which would eventually bring the supply of resources for each person back to its original level. Some economists contend that since the Industrial Revolution in the early 19th century, mankind has broken out of the trap. Others argue that the continuation of extreme poverty indicates that the Malthusian trap continues to operate. Others further argue that due to lack of food availability coupled with excessive pollution, developing countries show more evidence of the trap as compared to developed countries. A similar, more modern concept, is that of human overpopulation. (Full article...)
Richard H. Thaler (/ˈθeɪlər/; born September 12, 1945) is an American economist and the Charles R. Walgreen Distinguished Service Professor of Behavioral Science and Economics at the University of Chicago Booth School of Business. In 2015, Thaler was president of the American Economic Association.
Thaler is a theorist in behavioral economics. He has collaborated with Daniel Kahneman, Amos Tversky, and others in further defining that field. In 2018, he was elected a member in the National Academy of Sciences. (Full article...)
Elinor Claire "Lin" Ostrom (née Awan; August 7, 1933 – June 12, 2012) was an American political scientist and political economist whose work was associated with New Institutional Economics and the resurgence of political economy. In 2009, she was awarded the Nobel Memorial Prize in Economic Sciences for her "analysis of economic governance, especially the commons", which she shared with Oliver E. Williamson; she was the first woman to win the prize.
Trained in political science at UCLA, Ostrom was a faculty member at Indiana University Bloomington for 47 years. Beginning in the 1960s, Ostrom was involved in resource management policy and created a research center, the Workshop in Political Theory and Policy Analysis, which attracted scientists from different disciplines from around the world. Working and teaching at her center was created on the principle of a workshop, rather than a university with lectures and a strict hierarchy. Late in her career, she held an affiliation with Arizona State University. (Full article...)- Mutualism is an anarchist school of thought and economic theory that advocates for workers' control of the means of production, a free market made up of individual artisans, sole proprietorships and workers' cooperatives, and occupation and use property rights. As proponents of the labour theory of value and labour theory of property, mutualists oppose all forms of economic rent, profit and non-nominal interest, which they see as relying on the exploitation of labour. Mutualists seek to construct an economy without capital accumulation or concentration of land ownership. They also encourage the establishment of workers' self-management, which they propose could be supported through the issuance of mutual credit by mutual banks, with the aim of creating a federal society.
Mutualism has its roots in the utopian socialism of Robert Owen and Charles Fourier. It first developed a practical expression in Josiah Warren's community experiments in the United States, which he established according to the principles of equitable commerce based on a system of labor notes. Mutualism was first formulated into a comprehensive economic theory by the French anarchist Pierre-Joseph Proudhon, who proposed the abolition of unequal exchange and the establishment of a new economic system based on reciprocity. In order to establish such a system, he proposed the creation of a "People's Bank" that could issue mutual credit to workers and eventually replace the state; although his own attempts to establish such a system were foiled by the 1851 French coup d'état.

Karl Paul Polanyi (/poʊˈlænji/; Hungarian: Polányi Károly [ˈpolaːɲi ˈkaːroj]; 25 October 1886 – 23 April 1964) was an Austro-Hungarian economic historian, economic sociologist, and politician, best known for his book The Great Transformation, which questions the conceptual validity of self-regulating markets.In his writings, Polanyi advances the concept of the Double Movement, which refers to the dialectical process of marketization and push for social protection against that marketization. He argues that market-based societies in modern Europe were not inevitable but historically contingent. Polanyi is remembered best as the originator of substantivism, a cultural version of economics, which emphasizes the way economies are embedded in society and culture. This opinion is counter to mainstream economics but is popular in anthropology, economic history, economic sociology and political science.
Polanyi's approach to the ancient economies has been applied to a variety of cases, such as Pre-Columbian America and ancient Mesopotamia, although its utility to the study of ancient societies in general has been questioned. Polanyi's The Great Transformation became a model for historical sociology. His theories eventually became the foundation for the economic democracy movement. (Full article...)
Hans-Hermann Hoppe (/ˈhɒpə/; German: [ˈhɔpə]; born 2 September 1949) is a German-American academic associated with Austrian School economics, anarcho-capitalism, right-wing libertarianism, paleolibertarianism, and opposition to democracy. From 1986 until 2008 he was professor of economics at the University of Nevada, Las Vegas (UNLV). He is a senior fellow of the Mises Institute think tank. In 2006 he emigrated to Turkey and founded the Property and Freedom Society.
Hoppe has written extensive criticisms of democracy, notably in his 2001 book Democracy: The God That Failed. The book favors exclusionary covenant communities that are "founded for the purpose of protecting family and kin". A section of the book favoring exclusion of democrats and homosexuals from society helped popularize Hoppe on the far-right. Some of the speakers invited at his Property and Freedom Society conferences in Turkey have been white nationalists. (Full article...)- The neoclassical synthesis (NCS), or neoclassical–Keynesian synthesis, is an academic movement and paradigm in economics that worked towards reconciling the macroeconomic thought of John Maynard Keynes in his book The General Theory of Employment, Interest and Money (1936) with neoclassical economics.
The neoclassical synthesis is a macroeconomic theory that emerged in the mid-20th century, combining the ideas of neoclassical economics with Keynesian economics. The synthesis was an attempt to reconcile the apparent differences between the two schools of thought and create a more comprehensive theory of macroeconomics. (Full article...) 
Michał Kalecki (Polish: [ˈmixaw kaˈlɛt͡skʲi]; 22 June 1899 – 18 April 1970) was a Polish Marxian economist. Over the course of his life, Kalecki worked at the London School of Economics, University of Cambridge, University of Oxford, and Warsaw School of Economics, and was an economic advisor to the governments of Poland, France, Cuba, Israel, Mexico, and India. He also served as the deputy director of the United Nations Economic Department in New York City.
Kalecki has been called "one of the most distinguished economists of the 20th century" and "likely the most original one". It is often claimed that he developed many of the same ideas as John Maynard Keynes before Keynes but remains much less known to the English-speaking world. He offered a synthesis that integrated class analysis of Marxism and the new literature on oligopoly theory, and his work had a significant influence on both the neo-Marxian (Monopoly Capital) and post-Keynesian schools of economic thought. He was one of the first macroeconomists to apply mathematical models and statistical data to economic questions. Being also a political economist and a person of left-wing convictions, Kalecki emphasized the social aspects and consequences of economic policies. (Full article...)- Neo-Marxism is a collection of Marxist schools of thought that originated from 20th-century approaches to amend or extend Marxism and Marxist theory, typically by incorporating elements from other intellectual traditions such as critical theory, psychoanalysis, or existentialism. Neo-Marxism comes under the broader framework of the New Left. In a sociological sense, neo-Marxism adds Max Weber's broader understanding of social inequality, such as status and power, to Marxist philosophy.
As with many uses of the prefix neo-, some theorists and groups who are designated as neo-Marxists have attempted to supplement the perceived deficiencies of orthodox Marxism or dialectical materialism. Many prominent neo-Marxists, such as Herbert Marcuse and other members of the Frankfurt School, have historically been sociologists and psychologists. (Full article...)
Karl Marx (German: [ˈkaʁl ˈmaʁks]; 5 May 1818 – 14 March 1883) was a German philosopher, social and political theorist, and revolutionary socialist. He developed the theory of historical materialism, analysing societal structure and change, particularly class struggle under capitalism, and predicting the system's ultimate replacement by communism. Marx co-authored The Communist Manifesto (1848) with Friedrich Engels, and undertook a critique of classical political economy in his magnum opus, Das Kapital (1867–1894). His ideas and their later development, collectively known as Marxism, have had enormous influence on intellectual, political, and social history, and have inspired revolutionary movements in many countries.
Born in Trier in the Kingdom of Prussia, Marx earned a doctoral degree in philosophy from the University of Jena in 1841. He became involved in radical journalism and was influenced by the philosophy of Georg Wilhelm Friedrich Hegel and the Young Hegelians, whose ideas he critiqued in works such as The German Ideology. In Paris, Marx wrote his Economic and Philosophic Manuscripts of 1844 and began a close collaboration with Engels. After moving to Brussels, they were active in the Communist League, and in 1848 wrote The Communist Manifesto, which lays out a programme for revolution. Expelled from Germany after the Revolutions of 1848, Marx moved to London, where he wrote his Grundrisse notebooks and the three volumes of Das Kapital. He became a leading figure in the International Workingmen's Association (First International), in which he battled the influence of anarchists led by Mikhail Bakunin and celebrated the Paris Commune of 1871. In his late studies and his Critique of the Gotha Programme (1875), Marx theorized on the transition to a communist society. He died in 1883 and was buried in Highgate Cemetery. (Full article...)- Classical economics, also known as the classical school of economics or classical political economy, is a school of thought in political economy that flourished primarily in Britain in the late 18th and early-to-mid 19th century. It includes both the Smithian and Ricardian schools. Its main thinkers are held to be Adam Smith, Jean-Baptiste Say, David Ricardo, Thomas Robert Malthus, and John Stuart Mill. These economists produced a theory of market economies as largely self-regulating systems, governed by natural laws of production and exchange (famously captured by Adam Smith's metaphor of the invisible hand).
Adam Smith's The Wealth of Nations in 1776 is usually considered to mark the beginning of classical economics. The fundamental message in Smith's book was that the wealth of any nation was determined not by the gold in the monarch's coffers, but by its national income. This income was in turn based on the labor of its inhabitants, organized efficiently by the division of labour and the use of accumulated capital, which became one of classical economics' central concepts. (Full article...) - The Lausanne School of economics, sometimes referred to as the Mathematical School, refers to the neoclassical economics school of thought surrounding Léon Walras and Vilfredo Pareto. It is named after the University of Lausanne, at which both Walras and Pareto held professorships. Polish economist Leon Winiarski is also said to have been a member of the Lausanne School.

Francis Ysidro Edgeworth FBA (8 February 1845 – 13 February 1926) was an Anglo-Irish philosopher and political economist who made significant contributions to the methods of statistics during the 1880s. From 1891 onward, he was appointed the founding editor of The Economic Journal. (Full article...)- Monetary circuit theory is a heterodox theory of monetary economics, particularly money creation, often associated with the post-Keynesian school.
It holds that money is created endogenously by the banking sector, rather than exogenously by central bank lending; it is a theory of endogenous money. It is also called circuitism and the circulation approach. (Full article...)
Wilhelm Röpke (German: [ˈvɪlˌhɛlm ˈʁœpkə]; 10 October 1899 – 12 February 1966) was a German economist and social critic, one of the spiritual fathers of the social market economy. A professor of economics, first in Jena, then in Graz, Marburg, Istanbul, and finally Geneva, Röpke theorised and collaborated to organise the post-World War II economic re-awakening of the war-wrecked German economy, deploying a program referred to as ordoliberalism, a more conservative variant of German liberalism.
With Alfred Müller-Armack and Alexander Rüstow (sociological neoliberalism) and Walter Eucken and Franz Böhm (ordoliberalism) he elucidated the ideas, which then were introduced formally by Germany's post-World War II Minister for Economics Ludwig Erhard, operating under Konrad Adenauer's Chancellorship. Röpke and his colleagues' economic influence therefore is considered largely responsible for enabling Germany's post-World War II "economic miracle". Röpke was also a historian and was nominated to the Nobel Prize in Literature in 1965. (Full article...)
Sir John Richard Hicks (8 April 1904 – 20 May 1989) was a British economist. He is considered one of the most important and influential economists of the twentieth century. The most familiar of his many contributions in the field of economics were his statement of consumer demand theory in microeconomics, and the IS–LM model (1937), which summarised a Keynesian view of macroeconomics. His book Value and Capital (1939) significantly extended general-equilibrium and value theory. The compensated demand function is named the Hicksian demand function in memory of him.
In 1972 he received the Nobel Memorial Prize in Economic Sciences (jointly) for his pioneering contributions to general equilibrium theory and welfare theory. (Full article...)
Joseph Alois Schumpeter (German: [ˈʃʊmpeːtɐ]; February 8, 1883 – January 8, 1950) was an Austrian political economist. He served briefly as Finance Minister of Austria in 1919. In 1932, he emigrated to the United States to become a professor at Harvard University, where he remained until the end of his career, and in 1939 obtained American citizenship.
Schumpeter was one of the most influential economists of the early 20th century, and popularized creative destruction, a term coined by Werner Sombart. His magnum opus is considered to be Capitalism, Socialism and Democracy. (Full article...)- Mainstream economics is the body of knowledge, theories, and models of economics, as taught by universities worldwide, that are generally accepted by economists as a basis for discussion. Also known as orthodox economics, it can be contrasted to heterodox economics, which encompasses various schools or approaches that are only accepted by a minority of economists.
The economics profession has traditionally been associated with neoclassical economics. However, this association has been challenged by prominent historians of economic thought including David Colander. They argue the current economic mainstream theories, such as game theory, behavioral economics, industrial organization, information economics, and the like, share very little common ground with the initial axioms of neoclassical economics.

Robert Merton Solow, GCIH (/ˈsoʊloʊ/; August 23, 1924 – December 21, 2023) was an American economist known for his studies of economic growth and the development of the Solow–Swan model, for which he won the 1987 Nobel Memorial Prize in Economic Sciences.
He was Institute Professor Emeritus of Economics at the Massachusetts Institute of Technology, where he was a professor from 1949 on. He was awarded the John Bates Clark Medal in 1961, the Nobel Memorial Prize in Economic Sciences in 1987, and the Presidential Medal of Freedom in 2014. Four of his PhD students, George Akerlof, Joseph Stiglitz, Peter Diamond, and William Nordhaus, later received Nobel Memorial Prizes in Economic Sciences in their own right. (Full article...)
Amartya Kumar Sen (Bengali: [ˈɔmortːo ˈʃen]; born 3 November 1933) is an Indian economist and philosopher. Sen has taught and worked in England and the United States since 1972. In 1998, he received the Nobel Prize in Economic Sciences for his contributions to welfare economics. He has also made major contributions to social choice theory, economic and social justice, economic theories of famines, decision theory, development economics, public health, and the measures of well-being of countries.
Sen is currently the Thomas W. Lamont University Professor, and professor of economics and philosophy, at Harvard University. He previously served as master of Trinity College at the University of Cambridge. In 1999, he received India's highest civilian honour, Bharat Ratna, for his contribution to welfare economics. The German Publishers and Booksellers Association awarded him the 2020 Peace Prize of the German Book Trade for his pioneering scholarship addressing issues of global justice and combating social inequality in education and healthcare. (Full article...)- Agent-based computational economics (ACE) is the area of computational economics that studies economic processes, including whole economies, as dynamic systems of interacting agents. As such, it falls in the paradigm of complex adaptive systems. In corresponding agent-based models, the "agents" are "computational objects modeled as interacting according to rules" over space and time, not real people. The rules are formulated to model behavior and social interactions based on incentives and information. Such rules could also be the result of optimization, realized through use of AI methods (such as Q-learning and other reinforcement learning techniques).
As part of non-equilibrium economics, the theoretical assumption of mathematical optimization by agents in equilibrium is replaced by the less restrictive postulate of agents with bounded rationality adapting to market forces. ACE models apply numerical methods of analysis to computer-based simulations of complex dynamic problems for which more conventional methods, such as theorem formulation, may not find ready use. Starting from initial conditions specified by the modeler, the computational economy evolves over time as its constituent agents repeatedly interact with each other, including learning from interactions. In these respects, ACE has been characterized as a bottom-up culture-dish approach to the study of economic systems.

He was a professor of economics at New York University, Academic Director of the Berkley Center for Entrepreneurship and Innovation, and professor emeritus at Princeton University. He was a prolific author of more than eighty books and several hundred journal articles. He is the namesake of the Baumol effect.
Baumol wrote extensively about labor market and other economic factors that affect the economy. He also made significant contributions to the theory of entrepreneurship and the history of economic thought. He is among the most influential economists in the world according to IDEAS/RePEc. He was elected a Fellow of the American Academy of Arts and Sciences in 1971, the American Philosophical Society in 1977, and the United States National Academy of Sciences in 1987. (Full article...) - A mixed economy is an economic system that includes both elements associated with capitalism, such as private businesses, and ones associated with socialism, such as nationalized government services.
More specifically, a mixed economy may be variously defined as an economic system blending elements of a market economy with elements of a planned economy, markets with state interventionism, or private enterprise with public enterprise. Common to all mixed economies is a combination of free-market principles and principles of socialism. A mixed economy can be a reformist transitionary phase of a socialist economy that allows a substantial role for private enterprise and contracting within a dominant economic framework of public ownership. This can extend to a Soviet-type planned economy that has been reformed to incorporate a greater role for markets in the allocation of factors of production. (Full article...)
