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 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...)

Milton Friedman (/ˈfriːdmən/ ⓘ; July 31, 1912 – November 16, 2006) was an American economist and statistician who received the 1976 Nobel Memorial Prize in Economic Sciences for his research on consumption analysis, monetary history and theory and the complexity of stabilization policy. With George Stigler, Friedman was among the intellectual leaders of the Chicago school of economics, a neoclassical school of economic thought associated with the work of the faculty at the University of Chicago that rejected Keynesianism in favor of monetarism until the mid-1970s, when it turned to new classical macroeconomics heavily based on the concept of rational expectations. Several students, young professors and academics who were recruited or mentored by Friedman at Chicago went on to become leading economists, including Gary Becker, Robert Fogel, and Robert Lucas Jr.
Friedman's challenges to what he called "naive Keynesian theory" began with his interpretation of consumption, which tracks how consumers spend. He introduced a theory which would later become part of mainstream economics and he was among the first to propagate the theory of consumption smoothing. During the 1960s, he became the main advocate opposing both Marxist and Keynesian government and economic policies, and described his approach (along with mainstream economics) as using "Keynesian language and apparatus" yet rejecting its initial conclusions. He theorized that there existed a natural rate of unemployment and argued that unemployment below this rate would cause inflation to accelerate. He argued that the Phillips curve was in the long run vertical at the "natural rate" and predicted what would come to be known as stagflation. Friedman promoted a macroeconomic viewpoint known as monetarism and argued that a steady, small expansion of the money supply was the preferred policy, as compared to rapid, and unexpected changes. His ideas concerning monetary policy, taxation, privatization, and deregulation influenced government policies, especially during the 1980s. His monetary theory influenced the Federal Reserve's monetary policy in response to the 2008 financial crisis. (Full article...) -
Thomas Robert Malthus FRS (/ˈmælθəs/; 13/14 February 1766 – 29 December 1834) was an English economist, cleric, and scholar influential in the fields of political economy and demography.
In his 1798 book An Essay on the Principle of Population, Malthus observed that an increase in a nation's food production improved the well-being of the population, but the improvement was temporary because it led to population growth, which in turn restored the original per capita production level. In other words, humans had a propensity to use abundance for population growth rather than for maintaining a high standard of living, a view and stance that has become known as the "Malthusian trap" or the "Malthusian spectre". Populations had a tendency to grow until the lower class suffered hardship, want, and greater susceptibility to war, famine, and disease, a pessimistic view that is sometimes referred to as a Malthusian catastrophe. Malthus wrote in opposition to the popular view in 18th-century Europe that saw society as improving and in principle as perfectible. (Full article...) -
Oskar Ryszard Lange (Polish: [ˈlanɡɛ]; 27 July 1904 – 2 October 1965) was a Polish economist and diplomat. He is best known for advocating the use of market pricing tools in socialist systems and providing a model of market socialism. He responded to the economic calculation problem proposed by Ludwig von Mises and Friedrich Hayek by claiming that managers in a centrally-planned economy would be able to monitor supply and demand through increases and declines in inventories of goods, and advocated the nationalization of major industries. During his stay in the United States, Lange was an academic teacher and researcher in mathematical economics. Later in socialist Poland, he was a member of the Central Committee of the Polish United Workers' Party. (Full article...) -
Computational economics is an interdisciplinary research discipline that combines methods in computational science and economics to solve complex economic problems. This subject encompasses computational modeling of economic systems. Some of these areas are unique, while others established areas of economics by allowing robust data analytics and solutions of problems that would be arduous to research without computers and associated numerical methods.
Computational methods have been applied in various fields of economics research, including but not limiting to: (Full article...) -
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 of 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 may have contributed to war and motivated colonial expansion. Mercantilist theory varies in sophistication from one writer to another and has evolved over time.

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...) -
Arthur Cecil Pigou (/ˈpiːɡuː/; 18 November 1877 – 7 March 1959) was an English economist. As a teacher and builder of the School of Economics at the University of Cambridge, he trained and influenced many Cambridge economists who went on to take chairs of economics around the world. His work covered various fields of economics, particularly welfare economics, but also included business cycle theory, unemployment, public finance, index numbers, and measurement of national output. His reputation was affected adversely by influential economic writers who used his work as the basis on which to define their own opposing views. He reluctantly served on several public committees, including the Cunliffe Committee and the 1919 Royal Commission on income tax. (Full article...) -
Jan Tinbergen (/ˈtɪnbɜːrɡən/ TIN-bur-gən, Dutch: [jɑn ˈtɪmbɛrɣə(n)]; 12 April 1903 – 9 June 1994) was a Dutch economist who was awarded the first Nobel Memorial Prize in Economic Sciences in 1969, which he shared with Ragnar Frisch for having developed and applied dynamic models for the analysis of economic processes. He is widely considered to be one of the most influential economists of the 20th century and one of the founding fathers of econometrics.
His important contributions to econometrics include the development of the first macroeconometric models, the solution of the identification problem, and the understanding of dynamic models. Tinbergen was a founding trustee of Economists for Peace and Security. In 1945, he founded the Bureau for Economic Policy Analysis (CPB) and was the agency's first director. (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...) -
Hermann Heinrich Gossen (7 September 1810 – 13 February 1858) was a German economist who is often regarded as the first to elaborate, in detail, a general theory of marginal utility.
Prior to Gossen, a number of economic theorists, including Gabriel Cramer, Daniel Bernoulli, William Forster Lloyd, Nassau William Senior, and Jules Dupuit had employed or asserted the significance of some notion of marginal utility. But Cramer, Bernoulli, and Dupuit had focussed upon specific problems, Lloyd had not presented any applications of theory, and if Senior provided a detailed elaboration of the general theory he had developed, he had done so in language that caused his applications of theory to be missed by most readers.

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, and opposition to democracy. He is professor emeritus of economics at the University of Nevada, Las Vegas (UNLV), senior fellow of the Mises Institute think tank, and the founder and president of the Property and Freedom Society.
Hoppe has written extensively in opposition to 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. (Full article...) -
Ludwig Heinrich Edler von Mises (/vɒn ˈmiːzɪz/; German: [ˈluːtvɪç fɔn ˈmiːzəs]; September 29, 1881 – October 10, 1973) was an Austrian-American political economist and philosopher of the Austrian school. Mises wrote and lectured extensively on the social contributions of classical liberalism and the central role of consumers in a market economy. 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.
In 1940, Mises emigrated from Austria to the United States to escape the Nazis. On the day German forces entered Vienna, they raided his apartment, confiscating his papers and library, which were believed lost or destroyed until rediscovered decades later in Soviet archives. At the time, Mises was living in Geneva, Switzerland. However, with the imminent Nazi occupation of France threatening to isolate Switzerland within Axis-controlled territory, he and his wife fled through France—avoiding German patrols—and reached the United States via Spain and Portugal.

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.

William Stanley Jevons FRS (/ˈdʒɛvənz/; 1 September 1835 – 13 August 1882) was an English economist and logician.
Irving Fisher described Jevons's book A General Mathematical Theory of Political Economy (1862) as the start of the mathematical method in economics. It made the case that economics, as a science concerned with quantities, is necessarily mathematical. In so doing, it expounded upon the "final" (marginal) utility theory of value. Jevons' work, along with similar discoveries made by Carl Menger in Vienna (1871) and by Léon Walras in Switzerland (1874), marked the opening of a new period in the history of economic thought. Jevons's contribution to the marginal revolution in economics in the late 19th century established his reputation as a leading political economist and logician of the time. (Full article...) -

Gary Stanley Becker (/ˈbɛkər/; December 2, 1930 – May 3, 2014) was an American economist who received the 1992 Nobel Memorial Prize in Economic Sciences. He was a professor of economics and sociology at the University of Chicago, and was a leader of the third generation of the Chicago school of economics.
Becker was awarded the Nobel Memorial Prize in Economic Sciences in 1992 and received the United States Presidential Medal of Freedom in 2007. A 2011 survey of economics professors named Becker their favorite living economist over the age of 60, followed by Kenneth Arrow and Robert Solow. Economist Justin Wolfers called him "the most important social scientist in the past 50 years." (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.

Irving Fisher (February 27, 1867 – April 29, 1947) was an American economist, statistician, inventor, eugenicist and progressive social campaigner. He was one of the earliest American neoclassical economists, though his later work on debt deflation has been embraced by the post-Keynesian school. Joseph Schumpeter described him as "the greatest economist the United States has ever produced", an assessment later repeated by James Tobin and Milton Friedman.
Fisher made important contributions to utility theory and general equilibrium. He was also a pioneer in the rigorous study of intertemporal choice in markets, which led him to develop a theory of capital and interest rates. His research on the quantity theory of money inaugurated the school of macroeconomic thought known as "monetarism". Fisher was also a pioneer of econometrics, including the development of index numbers. Some concepts named after him include the Fisher equation, the Fisher hypothesis, the international Fisher effect, the Fisher separation theorem and Fisher market. (Full article...) -
New classical macroeconomics, sometimes simply called new classical economics, is a school of thought in macroeconomics that builds its analysis entirely on a neoclassical framework. Specifically, it emphasizes the importance of foundations based on microeconomics, especially rational expectations.
New classical macroeconomics strives to provide neoclassical microeconomic foundations for macroeconomic analysis. This is in contrast with its rival new Keynesian school that uses microfoundations, such as price stickiness and imperfect competition, to generate macroeconomic models similar to earlier, Keynesian ones.

Supply-side economics is a macroeconomic theory postulating that economic growth can be most effectively fostered by lowering taxes, decreasing regulation, and allowing free trade. According to supply-side economics theory, consumers will benefit from greater supply of goods and services at lower prices, and employment will increase. Supply-side fiscal policies are designed to increase aggregate supply, as opposed to aggregate demand, thereby expanding output and employment while lowering prices. Such policies are of several general varieties:
- Investments in human capital, such as education, healthcare, and encouraging the transfer of technologies and business processes, to improve productivity (output per worker). Encouraging globalized free trade via containerization is a major recent example.
- Tax reduction, to provide incentives to work, invest and take risks. Lowering income tax rates and eliminating or lowering tariffs are examples of such policies.
- Investments in new capital equipment and research and development (R&D), to further improve productivity. Allowing businesses to depreciate capital equipment more rapidly (e.g., over one year as opposed to 10) gives them an immediate financial incentive to invest in such equipment.
- Reduction in government regulations, to encourage business formation and expansion.
A basis of supply-side economics is the Laffer curve, a theoretical relationship between rates of taxation and government revenue. The Laffer curve suggests that when the tax level is too high, lowering tax rates will boost government revenue through higher economic growth, though the level at which rates are deemed "too high" is disputed. Critics also argue that several large tax cuts in the United States over the last 40 years have not increased revenue. (Full article...) -
The attention economy refers to the incentives of advertising-driven companies, in particular, to maximize the time and attention their users give to their product.
Attention economics is an approach to the management of information that treats human attention as a scarce commodity and applies economic theory to solve various information management problems. (Full article...) -
Behavioral economics is the study of the psychological (e.g. cognitive, behavioral, affective, social) factors involved in the decisions of individuals or institutions, and how these decisions deviate from those implied by traditional economic theory.
Behavioral economics is primarily concerned with the bounds of rationality of economic agents. Behavioral models typically integrate insights from psychology, neuroscience and microeconomic theory. (Full article...) -
Real business-cycle theory (RBC theory) is a class of new classical macroeconomics models in which business-cycle fluctuations are accounted for by real, in contrast to nominal, shocks. RBC theory sees business cycle fluctuations as the efficient response to exogenous changes in the real economic environment. That is, the level of national output necessarily maximizes expected utility.
In RBC models, business cycles are described as "real" because they reflect optimal adjustments by economic agents rather than failures of markets to clear. As a result, RBC theory suggests that governments should concentrate on long-term structural change rather than intervention through discretionary fiscal or monetary policy. These ideas are strongly associated with freshwater economics within the neoclassical economics tradition, particularly the Chicago School of Economics. (Full article...) -
Microeconomics analyzes the market mechanisms that enable buyers and sellers to establish relative prices among goods and services. Shown is a marketplace in Delhi.
Microeconomics is a branch of economics that studies the behavior of individuals and firms in making decisions regarding the allocation of scarce resources and the interactions among these individuals and firms. Microeconomics focuses on the study of individual markets, sectors, or industries as opposed to the economy as a whole, which is studied in macroeconomics.
One goal of microeconomics is to analyze the market mechanisms that establish relative prices among goods and services and allocate limited resources among alternative uses. Microeconomics shows conditions under which free markets lead to desirable allocations. It also analyzes market failure, where markets fail to produce efficient results. (Full article...) -
Karl Gunnar Myrdal (/ˈmɜːrdɑːl, ˈmɪər-/ MUR-dahl, MEER-; Swedish: [ˈɡɵ̌nːar ˈmy̌ːɖɑːl]; 6 December 1898 – 17 May 1987) was a Swedish economist and sociologist. In 1974, he received the Nobel Memorial Prize in Economic Sciences along with Friedrich Hayek for "their pioneering work in the theory of money and economic fluctuations and for their penetrating analysis of the interdependence of economic, social and institutional phenomena." When his wife, Alva Myrdal, received the Nobel Peace Prize in 1982, they became the fourth ever married couple to have won Nobel Prizes, and the first and only to win independent of each other (versus a shared Nobel Prize by scientist spouses).
Myrdal is best known in the United States for his study of race relations, which culminated in his book An American Dilemma: The Negro Problem and Modern Democracy. The study was influential in the 1954 landmark U.S. Supreme Court decision Brown v. Board of Education. In Sweden, his work and political influence were important to the establishment of the Folkhemmet and the welfare state. (Full article...)
