Introduction
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 basic elements within economies, including individual agents and markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyses economies as systems where production, distribution, consumption, savings, and investment expenditure interact, and factors affecting it: factors of production, such as labour, capital, land, and enterprise, inflation, economic growth, and public policies that have impact on these elements. It also seeks to analyse and describe the global economy. (Full article...)

Critique of political economy or simply the first critique of economy is a form of social critique that rejects the conventional ways of distributing resources. The critique also rejects what its advocates believe are unrealistic axioms, faulty historical assumptions, and taking conventional economic mechanisms as a given
or as transhistorical (true for all human societies for all time). The critique asserts the conventional economy is merely one of many types of historically specific ways to distribute resources, which emerged along with modernity (post-Renaissance Western society).
Critics of political economy do not necessarily aim to create their own theories regarding how to administer economies. Critics of economy commonly view "the economy" as a bundle of concepts and societal and normative practices, rather than being the result of any self-evident economic laws. Hence, they also tend to consider the views which are commonplace within the field of economics as faulty, or simply as pseudoscience. (Full article...) -
Economic democracy (sometimes called a democratic economy) is a socioeconomic philosophy that proposes to shift ownership and decision-making power from corporate shareholders and corporate managers (such as a board of directors) to a larger group of public stakeholders that includes workers, consumers, suppliers, communities and the broader public. No single definition or approach encompasses economic democracy, but most proponents claim that modern property relations externalize costs, subordinate the general well-being to private profit and deny the polity a democratic voice in economic policy decisions. In addition to these moral concerns, economic democracy makes practical claims, such as that it can compensate for capitalism's inherent effective demand gap.
Proponents of economic democracy generally argue that modern capitalism periodically results in economic crises, characterized by deficiency of effective demand; as society is unable to earn enough income to purchase its own production output. Corporate monopoly of common resources typically creates artificial scarcity, resulting in socio-economic imbalances that restrict workers from access to economic opportunity and diminish consumer purchasing power. Economic democracy has been proposed as a component of larger socioeconomic ideologies, as a stand-alone theory and as a variety of reform agendas. For example, as a means to securing full economic rights, it opens a path to full political rights, defined as including the former. Both market and non-market theories of economic democracy have been proposed. As a reform agenda, supporting theories and real-world examples can include decentralization, democratic cooperatives, public banking, fair trade and the regionalization of food production and currency.

John Maynard Keynes, 1st Baron Keynes CB, FBA (/keɪnz/ KAYNZ; 5 June 1883 – 21 April 1946), was an English economist and philosopher whose ideas fundamentally changed the theory and practice of macroeconomics and the economic policies of governments. Originally trained in mathematics, he built on and greatly refined earlier work on the causes of business cycles. One of the most influential economists of the 20th century, he produced writings that are the basis for the school of thought known as Keynesian economics, and its various offshoots. His ideas, reformulated as New Keynesianism, are fundamental to mainstream macroeconomics. He is known as the "father of macroeconomics".
During the Great Depression of the 1930s, Keynes spearheaded a revolution in economic thinking, challenging the ideas of neoclassical economics that held that free markets would, in the short to medium term, automatically provide full employment, as long as workers were flexible in their wage demands. He argued that aggregate demand (total spending in the economy) determined the overall level of economic activity, and that inadequate aggregate demand could lead to prolonged periods of high unemployment, and since wages and labour costs are rigid downwards the economy will not automatically rebound to full employment. Keynes advocated the use of fiscal and monetary policies to mitigate the adverse effects of economic recessions and depressions. After the 1929 crisis, Keynes also turned away from a fundamental pillar of neoclassical economics: free trade. He criticized Ricardian comparative advantage theory (the foundation of free trade), considering the theory's initial assumptions unrealistic, and became definitively protectionist. He detailed these ideas in his magnum opus, The General Theory of Employment, Interest and Money, published in early 1936. By the late 1930s, leading Western economies had begun adopting Keynes's policy recommendations. Almost all capitalist governments had done so by the end of the two decades following Keynes's death in 1946. As a leader of the British delegation, Keynes participated in the design of the international economic institutions established after the end of World War II but was overruled by the American delegation on several aspects.

Kenneth Joseph Arrow (August 23, 1921 – February 21, 2017) was an American economist, mathematician and political theorist. He received the John Bates Clark Medal in 1957, and the Nobel Memorial Prize in Economic Sciences in 1972, along with John Hicks.
In economics, Arrow was a major figure in postwar neoclassical economic theory. Four of his students (Roger Myerson, Eric Maskin, John Harsanyi, and Michael Spence) went on to become Nobel laureates themselves. His contributions to social choice theory, notably his “impossibility theorem", and his work on general equilibrium analysis are significant. He work in many other areas of economics, including endogenous growth theory and the economics of information, was also foundational. (Full article...) -
Heterodox economics family tree.
Heterodox economics is a broad, relative term referring to schools of economic thought which are not commonly perceived as belonging to mainstream economics. There is no absolute definition of what constitutes heterodox economic thought, as it is defined in constrast to the most prominent, influential or popular schools of thought in a given time and place.
Groups typically classed as heterodox in current discourse include the Austrian, ecological, Marxist-historical, post-autistic, and modern monetary approaches. (Full article...) -
Herbert Alexander Simon (June 15, 1916 – February 9, 2001) was an American scholar whose work also influenced the fields of computer science, economics, and cognitive psychology. His primary research interest was decision-making within organizations and he is best known for the theories of "bounded rationality" and "satisficing". He received the Turing Award in 1975 and the Nobel Memorial Prize in Economic Sciences in 1978. His research was noted for its interdisciplinary nature, spanning the fields of cognitive science, computer science, public administration, management, and political science. He was at Carnegie Mellon University for most of his career, from 1949 to 2001, where he helped found the Carnegie Mellon School of Computer Science, one of the first such departments in the world.
Notably, Simon was among the pioneers of several modern-day scientific domains such as artificial intelligence, information processing, decision-making, problem-solving, organization theory, and complex systems. He was among the earliest to analyze the architecture of complexity and to propose a preferential attachment mechanism to explain power law distributions. (Full article...) -
William Jack Baumol (February 26, 1922 – May 4, 2017) was an American economist. 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.

Seaport at sunset, a painting by Claude Lorrain, completed in 1639 at the height of mercantilism
Mercantilism is a nationalist economic policy that is designed to maximize the exports and minimize the imports for an economy. In other words, it seeks to maximize the accumulation of resources within the country and use those resources for one-sided trade.
The concept aims to reduce a possible current account deficit or reach a current account surplus, and it includes measures aimed at accumulating monetary reserves by a positive balance of trade, especially of finished goods. Historically, such policies might have contributed to war and motivated colonial expansion. Mercantilist theory varies in sophistication from one writer to another and has evolved over time.

François Quesnay (French: [fʁɑ̃swa kɛnɛ]; 4 June 1694 – 16 December 1774) was a French economist and physician of the Physiocratic school. He is known for publishing the "Tableau économique" (Economic Table) in 1758, which provided the foundations of the ideas of the Physiocrats. This was perhaps the first work attempting to describe the workings of the economy in an analytical way, and as such can be viewed as one of the first important contributions to economic thought. His Le Despotisme de la Chine, written in 1767, describes Chinese politics and society, and his own political support for enlightened despotism. (Full article...) -
Robert Emerson Lucas Jr. (September 15, 1937 – May 15, 2023) was an American economist at the University of Chicago. Widely regarded as the central figure in the development of the new classical approach to macroeconomics, he received the Nobel Memorial Prize in Economic Sciences in 1995 "for having developed and applied the hypothesis of rational expectations, and thereby having transformed macroeconomic analysis and deepened our understanding of economic policy". N. Gregory Mankiw characterized him as "the most influential macroeconomist of the last quarter of the 20th century". In 2020, he ranked as the 10th most cited economist in the world.

Game theory is the study of mathematical models of strategic interactions. It has applications in many fields of social science, and is used extensively in economics, logic, systems science and computer science. Initially, game theory addressed two-person zero-sum games, in which a participant's gains or losses are exactly balanced by the losses and gains of the other participant. In the 1950s, it was extended to the study of non zero-sum games, and was eventually applied to a wide range of behavioral relations. It is now an umbrella term for the science of rational decision making in humans, animals, and computers.
Modern game theory began with the idea of mixed-strategy equilibria in two-person zero-sum games and its proof by John von Neumann. Von Neumann's original proof used the Brouwer fixed-point theorem on continuous mappings into compact convex sets, which became a standard method in game theory and mathematical economics. His paper was followed by Theory of Games and Economic Behavior (1944), co-written with Oskar Morgenstern, which considered cooperative games of several players. The second edition provided an axiomatic theory of expected utility, which allowed mathematical statisticians and economists to treat decision-making under uncertainty. (Full article...) -
Post-Keynesian economics is a school of economic thought with its origins in The General Theory of John Maynard Keynes, with subsequent development influenced to a large degree by Michał Kalecki, Joan Robinson, Nicholas Kaldor, Sidney Weintraub, Paul Davidson, Piero Sraffa and Jan Kregel. Historian Robert Skidelsky argues that the post-Keynesian school has remained closest to the spirit of Keynes' original work. It is a heterodox approach to economics. (Full article...)

Thermoeconomics, also referred to as biophysical economics, is a school of heterodox economics that applies the laws of statistical mechanics to economic theory. Thermoeconomics can be thought of as the statistical physics of economic value and is a subfield of econophysics.
It is the study of the ways and means by which human societies procure and use energy and other biological and physical resources to produce, distribute, consume and exchange goods and services, while generating various types of waste and environmental impacts. Biophysical economics builds on both social sciences and natural sciences to overcome some of the most fundamental limitations and blind spots of conventional economics. It makes it possible to understand some key requirements and framework conditions for economic growth, as well as related constraints and boundaries. (Full article...) -
Evolutionary economics is a school of economic thought that is inspired by evolutionary biology. Although not defined by a strict set of principles and uniting various approaches, it treats economic development as a process rather than an equilibrium and emphasizes change (qualitative, organisational, and structural), innovation, complex interdependencies, self-evolving systems, and limited rationality as the drivers of economic evolution. The support for the evolutionary approach to economics in recent decades seems to have initially emerged as a criticism of the mainstream neoclassical economics, but by the beginning of the 21st century it had become part of the economic mainstream itself.
Evolutionary economics does not take the characteristics of either the objects of choice or of the decision-maker as fixed. Rather, it focuses on the non-equilibrium processes that transform the economy from within and their implications, considering interdependencies and feedback. The processes in turn emerge from the actions of diverse agents with bounded rationality who may learn from experience and interactions and whose differences contribute to the change.

Thomas Sowell (/soʊl/ SOHL born June 30, 1930) is an American economist, social philosopher and political commentator. He is a senior fellow at the Hoover Institution. With widely published commentary and books—and as a guest on TV and radio—he is a well-known voice in the American conservative movement as a prominent black conservative. He was a recipient of the National Humanities Medal from President George W. Bush in 2002.
Sowell was born in Gastonia, North Carolina and grew up in Harlem, New York City. Due to poverty and difficulties at home, he dropped out of Stuyvesant High School and worked various odd jobs, eventually serving in the United States Marine Corps during the Korean War. Afterward, he took night classes at Howard University and then attended Harvard University, where he graduated magna cum laude in 1958. He earned a master's degree in economics from Columbia University the next year and a doctorate in economics from the University of Chicago in 1968. In his academic career, he held professorships at Cornell University, Brandeis University and the University of California, Los Angeles. He has also worked at think tanks including the Urban Institute. Since 1977, he has worked at the Hoover Institution at Stanford University, where he is the Rose and Milton Friedman Senior Fellow on Public Policy. (Full article...) -
Joseph Eugene Stiglitz (/ˈstɪɡlɪts/; born February 9, 1943) is an American New Keynesian economist, a public policy analyst, political activist, and a professor at Columbia University. He is a recipient of the Nobel Memorial Prize in Economic Sciences (2001) and the John Bates Clark Medal (1979). He is a former senior vice president and chief economist of the World Bank. He is also a former member and chairman of the US Council of Economic Advisers. He is known for his support for the Georgist public finance theory and for his critical view of the management of globalization, of laissez-faire economists (whom he calls "free-market fundamentalists"), and of international institutions such as the International Monetary Fund and the World Bank.
In 2000, Stiglitz founded the Initiative for Policy Dialogue (IPD), a think tank on international development based at Columbia University. He has been a member of the Columbia faculty since 2001 and received the university's highest academic rank (university professor) in 2003. He was the founding chair of the university's Committee on Global Thought. He also chairs the University of Manchester's Brooks World Poverty Institute. He was a member of the Pontifical Academy of Social Sciences. In 2009, the President of the United Nations General Assembly Miguel d'Escoto Brockmann, appointed Stiglitz as the chairman of the U.N. Commission on Reforms of the International Monetary and Financial System, where he oversaw suggested proposals and commissioned a report on reforming the international monetary and financial system. He served as the chair of the international Commission on the Measurement of Economic Performance and Social Progress, appointed by the French President Sarkozy, which issued its report in 2010, Mismeasuring our Lives: Why GDP doesn't add up, and currently serves as co-chair of its successor, the High Level Expert Group on the Measurement of Economic Performance and Social Progress. From 2011 to 2014, Stiglitz was the president of the International Economic Association (IEA). He presided over the organization of the IEA triennial world congress held near the Dead Sea in Jordan in June 2014. (Full article...) -
Daniel Friedrich List (6 August 1789 – 30 November 1846) was a German entrepreneur, diplomat, economist and political theorist who developed the nationalist theory of political economy in both Europe and the United States. He was a forefather of the German historical school of economics and argued for the Zollverein (a pan-German customs union) from a nationalist standpoint. He advocated raising tariffs on imported goods while supporting free trade of domestic goods and stated the cost of a tariff should be seen as an investment in a nation's future productivity. His theories and writing also influenced the American school of economics.
List was a political liberal who collaborated with Karl von Rotteck and Carl Theodor Welcker on the Rotteck-Welckersches Staatslexikon, an encyclopedia of political science that advocated constitutional liberalism and which influenced the Vormärz. At the time in Europe, liberal and nationalist ideas were almost inseparably linked, and political liberalism was not yet attached to what was later considered "economic liberalism." Emmanuel Todd considers List a forerunner to John Maynard Keynes as a theorist of "moderate or regulated capitalism." (Full article...) -
Ludwig Heinrich Edler von Mises (German: [ˈluːtvɪç fɔn ˈmiːzəs]; 29 September 1881 – 10 October 1973) was an Austrian-American economist, logician, sociologist and philosopher of economics of the Austrian school. Mises wrote and lectured extensively on the societal contributions of classical liberalism and the power of consumers. He is best known for his work in praxeology, particularly for studies comparing communism and capitalism, as well as for being a defender of classical liberalism in the face of rising illiberalism and authoritarianism throughout much of Europe during the 20th century.
Mises emigrated from Austria to the United States in 1940, fleeing from Nazis who on the first day the German Army entered Vienna rushed into the von Mises apartment in Vienna, apparently looking for him, and confiscated his library and papers. Mises was in Geneva, Switzerland at the time, but when the German invasion of France was about to leave Switzerland completely surrounded by Fascist and Nazi controlled territory, von Mises and his wife found it necessary to flee through France dodging German troops, to get to the US via Spain and Portugal. Since the mid-20th century, both libertarian movements and the field of economics as a whole, have been strongly influenced by Mises's writings. Mises's student Friedrich Hayek viewed Mises as one of the major figures in the revival of classical liberalism in the post-war era. Hayek's work The Transmission of the Ideals of Freedom (1951) pays high tribute to the influence of Mises in the 20th-century libertarian movement. Economist Tyler Cowen lists his writings as "the most important works of the 20th century" and as "among the most important economics articles, ever". (Full article...) -

Jean-Baptiste Say (French: [ʒɑ̃batist sɛ]; 5 January 1767 – 15 November 1832) was a liberal French economist and businessman who argued in favor of competition, free trade and lifting restraints on business. He is best known for Say's law—also known as the law of markets—which he popularized, although scholars disagree as to whether it was Say who first articulated the theory. Moreover, he was one of the first economists to study entrepreneurship and conceptualized entrepreneurs as organizers and leaders of the economy. He was also closely involved in the development of the École spéciale de commerce et d'industrie (ESCP), historically the first business school to be established. (Full article...) -
Modern monetary theory or modern money theory (MMT) is a heterodox macroeconomic theory that describes currency as a public monopoly and unemployment as evidence that a currency monopolist is overly restricting the supply of the financial assets needed to pay taxes and satisfy savings desires. According to MMT, governments do not need to worry about accumulating debt since they can pay interest by printing money. MMT argues that the primary risk once the economy reaches full employment is inflation, which acts as the only constraint on spending. MMT also argues that inflation can be controlled by increasing taxes on everyone, to reduce the spending capacity of the private sector.[verification needed]
MMT is opposed to the mainstream understanding of macroeconomic theory and has been criticized heavily by many mainstream economists. MMT is also strongly opposed by members of the Austrian school of economics, with Murray Rothbard stating that MMT practices are equivalent to "counterfeiting" and that government control of the money supply will inevitably lead to hyperinflation.

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 the term "creative destruction", coined by Werner Sombart. His magnum opus is considered Capitalism, Socialism and Democracy. (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.

Simon Smith Kuznets (/ˈkʌznɛts/ KUZ-nets; Russian: Семён Абра́мович Кузне́ц, IPA: [sʲɪˈmʲɵn ɐˈbraməvʲɪtɕ kʊzʲˈnʲets]; April 30, 1901 – July 8, 1985) was a Russian-born American economist and statistician who received the 1971 Nobel Memorial Prize in Economic Sciences "for his empirically founded interpretation of economic growth which has led to new and deepened insight into the economic and social structure and process of development."
Kuznets made a decisive contribution to the transformation of economics into an empirical science and to the formation of quantitative economic history. Kuznets pioneered the concept of gross domestic product, which seeks to capture all economic production in a state by a single measure. (Full article...) -
John Kenneth Galbraith OC (October 15, 1908 – April 29, 2006), also known as Ken Galbraith, was a Canadian-American economist, diplomat, public official, and intellectual. His books on economic topics were bestsellers from the 1950s through the 2000s. As an economist, he leaned toward post-Keynesian economics from an institutionalist perspective.
Galbraith was a long-time Harvard faculty member and stayed with Harvard University for half a century as a professor of economics. He was a prolific author and wrote four dozen books, including several novels, and published more than a thousand articles and essays on various subjects. Among his works was a trilogy on economics, American Capitalism (1952), The Affluent Society (1958), and The New Industrial State (1967). (Full article...)
