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...)

- Image 1Computational 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...) - Image 2Supply-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. A 2012 poll of leading economists found none agreed that reducing the US federal income tax rate would result in higher annual tax revenue within five years. Critics also argue that several large tax cuts in the United States over the last 40 years have not increased revenue. (Full article...) - Image 3
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.

From an economic perspective, contract theory studies how economic actors can and do construct contractual arrangements, generally in the presence of information asymmetry. Because of its connections with both agency and incentives, contract theory is often categorized within a field known as law and economics. One prominent application of it is the design of optimal schemes of managerial compensation. In the field of economics, the first formal treatment of this topic was given by Kenneth Arrow in the 1960s. In 2016, Oliver Hart and Bengt R. Holmström both received the Nobel Memorial Prize in Economic Sciences for their work on contract theory, covering many topics from CEO pay to privatizations. Holmström focused more on the connection between incentives and risk, while Hart on the unpredictability of the future that creates holes in contracts. (Full article...) - Image 5
Alfred Marshall FBA (26 July 1842 – 13 July 1924) was an English economist, and was one of the most influential economists of his time. His book Principles of Economics (1890) was the dominant economic textbook in England for many years. It brought the ideas of supply and demand, marginal utility, and costs of production into a coherent whole. He is known as one of the founders of neoclassical economics. (Full article...) - Image 6
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.

Anarchists are anti-authoritarian and anti-capitalist, with anarchism usually referred to as a form of libertarian socialism, i.e. a stateless system of socialism. Anarchists support personal property (defined in terms of possession and use, i.e. mutualist usufruct) and oppose capital concentration, interest, monopoly, private ownership of productive property such as the means of production (capital, land and the means of labor), profit, rent, usury and wage slavery which are viewed as inherent to capitalism.
Anarchism is often considered a radical left-wing or far-left movement and much of its economics as well as legal philosophy reflect anti-authoritarian, anti-statist and libertarian interpretations of left-wing and socialist politics such as communism, collectivism, free-market, individualism, mutualism, participism and syndicalism, among other libertarian socialist economics. The majority of anarchist theorists do not consider anarcho-capitalism as a part of the anarchist movement due to the fact that anarchism has historically been an anti-capitalist movement and seen as incompatible with capitalism. Unlike anarcho-capitalists, the free market individualist anarchists retain the labor theory of value and socialist doctrines. (Full article...) - Image 8
Joan Violet Robinson FBA (née Maurice; 31 October 1903 – 5 August 1983) was a British economist known for her wide-ranging contributions to economic theory. One of the most prominent economists of the century, Joan Robinson incarnated the "Cambridge School" in most of its guises in the 20th century. She started out as a Marshallian; became, after 1936, one of the earliest and most ardent Keynesians; and ended up as a leader of the Neo-Ricardian and Post-Keynesian schools. (Full article...) - Image 9Disequilibrium macroeconomics is a tradition of research centered on the role of disequilibrium in economics. This approach is also known as non-Walrasian theory, equilibrium with rationing, the non-market clearing approach, and non-tâtonnement theory. Early work in the area was done by Don Patinkin, Robert W. Clower, and Axel Leijonhufvud. Their work was formalized into general disequilibrium models, which were very influential in the 1970s. American economists had mostly abandoned these models by the late 1970s, but French economists continued work in the tradition and developed fixprice models. (Full article...)

Wilhelm Röpke
Wilhelm Röpke (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...) - Image 11Post-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...)

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...) - Image 13
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.
After graduating with a B.A. and Ph.D. in political science from UCLA, Ostrom lived in Bloomington, Indiana, and served on the faculty of Indiana University, with a late-career affiliation with Arizona State University. She was a Distinguished Professor at Indiana University and the Arthur F. Bentley Professor of Political Science and co-director of the Workshop in Political Theory and Policy Analysis at Indiana University, as well as research professor and the founding director of the Center for the Study of Institutional Diversity at Arizona State University in Tempe. She was a lead researcher for the Sustainable Agriculture and Natural Resource Management Collaborative Research Support Program (SANREM CRSP), managed by Virginia Tech and funded by USAID. Beginning in 2008, she and her husband Vincent Ostrom advised the journal Transnational Corporations Review. (Full article...) - Image 14
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. (Full article...) - Image 15Economic 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.

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.

Carl Menger von Wolfensgrün (/ˈmɛŋɡər/; German: [ˈmɛŋɐ]; 28 February 1840 – 26 February 1921) was an Austrian economist and the founder of the Austrian School of economics. Menger contributed to the development of the theories of marginalism and marginal utility, which rejected cost-of-production theory of value, such as developed by the classical economists such as Adam Smith and David Ricardo. As a departure from such, he would go on to call his resultant perspective, the subjective theory of value. (Full article...) - Image 18
Marie-Esprit-Léon Walras (French: [valʁas]; 16 December 1834 – 5 January 1910) was a French mathematical economist and Georgist. He formulated the marginal theory of value (independently of William Stanley Jevons and Carl Menger) and pioneered the development of general equilibrium theory. Walras is best known for his book Éléments d'économie politique pure, a work that has contributed greatly to the mathematization of economics through the concept of general equilibrium. The definition of the role of the entrepreneur found in it was also taken up and amplified by Joseph Schumpeter.
For Walras, exchanges only take place after a Walrasian tâtonnement (French for "trial and error"), guided by the auctioneer, has made it possible to reach market equilibrium. It was the general equilibrium obtained from a single hypothesis, rarity, that led Joseph Schumpeter to consider him "the greatest of all economists". The notion of general equilibrium was very quickly adopted by major economists such as Vilfredo Pareto, Knut Wicksell and Gustav Cassel. John Hicks and Paul Samuelson used the Walrasian contribution in the elaboration of the neoclassical synthesis. For their part, Kenneth Arrow and Gérard Debreu, from the perspective of a logician and a mathematician, determined the conditions necessary for equilibrium.

Behavioral economics is primarily concerned with the bounds of rationality of economic agents. Behavioral models typically integrate insights from psychology, neuroscience and microeconomic theory. The study of behavioral economics includes how market decisions are made and the mechanisms that drive public opinion. (Full article...) - Image 20Marginalism is a theory of economics that attempts to explain the discrepancy in the value of goods and services by reference to their secondary, or marginal, utility. It states that the reason why the price of diamonds is higher than that of water, for example, owes to the greater additional satisfaction of the diamonds over the water. Thus, while the water has greater total utility, the diamond has greater marginal utility.
Although the central concept of marginalism is that of marginal utility, marginalists, following the lead of Alfred Marshall, drew upon the idea of marginal physical productivity in explanation of cost. The neoclassical tradition that emerged from British marginalism abandoned the concept of utility and gave marginal rates of substitution a more fundamental role in analysis. Marginalism is an integral part of mainstream economic theory. (Full article...) - Image 21New 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 rigorous 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.

Economic history is the study of history using methodological tools from economics or with a special attention to economic phenomena. Research is conducted using a combination of historical methods, statistical methods and the application of economic theory to historical situations and institutions. The field can encompass a wide variety of topics, including equality, finance, technology, labour, and business. It emphasizes historicizing the economy itself, analyzing it as a dynamic entity and attempting to provide insights into the way it is structured and conceived.
Using both quantitative data and qualitative sources, economic historians emphasize understanding the historical context in which major economic events take place. They often focus on the institutional dynamics of systems of production, labor, and capital, as well as the economy's impact on society, culture, and language. Scholars of the discipline may approach their analysis from the perspective of different schools of economic thought, such as mainstream economics, Austrian economics, Marxian economics, the Chicago school of economics, and Keynesian economics.

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...) - Image 24
Paul Robin Krugman (/ˈkrʊɡmən/ ⓘ KRUUG-mən; born February 28, 1953) is an American economist who is the Distinguished Professor of Economics at the Graduate Center of the City University of New York and a columnist for The New York Times. In 2008, Krugman was the sole winner of the Nobel Memorial Prize in Economic Sciences for his contributions to new trade theory and new economic geography. The Prize Committee cited Krugman's work explaining the patterns of international trade and the geographic distribution of economic activity, by examining the effects of economies of scale and of consumer preferences for diverse goods and services.
Krugman was previously a professor of economics at MIT, and, later, at Princeton University. He retired from Princeton in June 2015, and holds the title of professor emeritus there. He also holds the title of Centennial Professor at the London School of Economics. Krugman was President of the Eastern Economic Association in 2010, and is among the most influential economists in the world. He is known in academia for his work on international economics (including trade theory and international finance), economic geography, liquidity traps, and currency crises.
