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...)

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...) -
Thomas Robert Malthus, after whom Malthusianism is named
Malthusianism is the 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 crisis, Point of Crisis, or Malthusian crunch) occurs when population growth outpaces agricultural production, causing famine or war. Initially, right before the crisis, 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. As time goes on, and asset prices keep increasing, social unrest occurs, which ultimately causes a major war, revolution, or a famine. Societal collapse is an extreme but possible outcome from this process. Such a catastrophe inevitably has the effect of forcing 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...) -
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 Keynesian government 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 global financial crisis of 2007–2008. (Full article...) -

Decision theory (or the theory of choice) is a branch of applied probability theory and analytic philosophy concerned with the theory of making decisions based on assigning probabilities to various factors and assigning numerical consequences to the outcome.
There are three branches of decision theory:- Normative decision theory: Concerned with the identification of optimal decisions, where optimality is often determined by considering an ideal decision-maker who is able to calculate with perfect accuracy and is in some sense fully rational.
- Prescriptive decision theory: Concerned with describing observed behaviors through the use of conceptual models, under the assumption that those making the decisions are behaving under some consistent rules.
- Descriptive decision theory: Analyzes how individuals actually make the decisions that they do.

The historical school of economics was an approach to academic economics and to public administration that emerged in the 19th century in Germany, and held sway there until well into the 20th century. The professors involved compiled massive economic histories of Germany and Europe. Numerous Americans were their students. The school was opposed by theoretical economists. Prominent leaders included Gustav von Schmoller (1838–1917), and Max Weber (1864–1920) in Germany, and Joseph Schumpeter (1883–1950) in Austria and the United States. (Full article...)

Daniel Friedrich List (6 August 1789 – 30 November 1846) was a German 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.
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...) -
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...) -
Johann Heinrich von Thünen (24 June 1783 – 22 September 1850), sometimes spelled Thuenen, was a prominent nineteenth-century economist and a native of Mecklenburg-Strelitz, now in northern Germany.
Even though he never held a professorial position, von Thunen had substantial influence on economics. He has been described as one of the founders of agricultural economics and economic geography. He made substantial contributions to economic debates on rent, land use, and wages. (Full article...) -

Neo-Marxism is a collection of Marxist schools of thought originating 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...) -
Humanistic economics is a distinct pattern of economic thought with old historical roots that have been more recently invigorated by E. F. Schumacher's Small Is Beautiful: Economics as if People Mattered (1973). Proponents argue for "persons-first" economic theories as opposed to mainstream economic theories which are understood as often emphasizing financial gain over human well-being. In particular, the overly abstract human image implicit in mainstream economics is critically analyzed and instead it attempts a rethinking of economic principles, policies and institutions based on a richer and more balanced view of human nature.

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.

Bernard Mandeville, or Bernard de Mandeville (/ˈmændəˌvɪl/; 15 November 1670 – 21 January 1733), was an Anglo-Dutch philosopher, political economist, satirist, writer and physician. Born in Rotterdam, he lived most of his life in England and used English for most of his published works. He became famous for The Fable of the Bees. (Full article...) -
Michał Kalecki (Polish pronunciation: [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...) -
Vilfredo Federico Damaso Pareto (born Wilfried Fritz Pareto; 15 July 1848 – 19 August 1923) was an Italian polymath, whose areas of interest included sociology, civil engineering, economics, political science, and philosophy. He made several important contributions to economics, particularly in the study of income distribution and in the analysis of individuals' choices. He was also responsible for popularising the use of the term "elite" in social analysis.
He introduced the concept of Pareto efficiency and helped develop the field of microeconomics. He was also the first to claim that income follows a Pareto distribution, which is a power law probability distribution. The Pareto principle was named after him, and it was built on his observations that 80% of the wealth in Italy belonged to about 20% of the population. He also contributed to the fields of sociology and mathematics. (Full article...) -
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. 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.

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...) -
Herbert Alexander Simon (June 15, 1916 – February 9, 2001) was an American political scientist 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 Nobel Memorial Prize in Economic Sciences in 1978 and the Turing Award in computer science in 1975. 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...) -
Experimental economics is the application of experimental methods to study economic questions. Data collected in experiments are used to estimate effect size, test the validity of economic theories, and illuminate market mechanisms. Economic experiments usually use cash to motivate subjects, in order to mimic real-world incentives. Experiments are used to help understand how and why markets and other exchange systems function as they do. Experimental economics have also expanded to understand institutions and the law (experimental law and economics).
A fundamental aspect of the subject is design of experiments. Experiments may be conducted in the field or in laboratory settings, whether of individual or group behavior. (Full article...) -
Wassily Wassilyevich Leontief (Russian: Васи́лий Васи́льевич Лео́нтьев; August 5, 1905 – February 5, 1999), was a Soviet-American economist known for his research on input–output analysis and how changes in one economic sector may affect other sectors.
Leontief won the Nobel Memorial Prize in Economic Sciences in 1973, and four of his doctoral students have also been awarded the prize (Paul Samuelson 1970, Robert Solow 1987, Vernon L. Smith 2002, Thomas Schelling 2005). (Full article...) -
Ecological economics, bioeconomics, ecolonomy, eco-economics, or ecol-econ is both a transdisciplinary and an interdisciplinary field of academic research addressing the interdependence and coevolution of human economies and natural ecosystems, both intertemporally and spatially. By treating the economy as a subsystem of Earth's larger ecosystem, and by emphasizing the preservation of natural capital, the field of ecological economics is differentiated from environmental economics, which is the mainstream economic analysis of the environment. One survey of German economists found that ecological and environmental economics are different schools of economic thought, with ecological economists emphasizing strong sustainability and rejecting the proposition that physical (human-made) capital can substitute for natural capital (see the section on weak versus strong sustainability below).
Ecological economics was founded in the 1980s as a modern discipline on the works of and interactions between various European and American academics (see the section on History and development below). The related field of green economics is in general a more politically applied form of the subject. (Full article...) -
Georgist campaign button from the 1890s in which the cat on the badge refers to a slogan "Do you see the cat?" to draw analogy to the land question
Georgism, also called in modern times Geoism, and known historically as the single tax movement, is an economic ideology holding that people should own the value that they produce themselves, while the economic rent derived from land—including from all natural resources, the commons, and urban locations—should belong equally to all members of society. Developed from the writings of American economist and social reformer Henry George, the Georgist paradigm seeks solutions to social and ecological problems, based on principles of land rights and public finance that attempt to integrate economic efficiency with social justice.
Georgism is concerned with the distribution of economic rent caused by land ownership, natural monopolies, pollution rights, and control of the commons, including title of ownership for natural resources and other contrived privileges (e.g., intellectual property). Any natural resource that is inherently limited in supply can generate economic rent, but the classical and most significant example of land monopoly involves the extraction of common ground rent from valuable urban locations. Georgists argue that taxing economic rent is efficient, fair, and equitable. The main Georgist policy recommendation is a tax assessed on land value, arguing that revenues from a land value tax (LVT) can be used to reduce or eliminate existing taxes (such as on income, trade, or purchases) that are unfair and inefficient. Some Georgists also advocate for the return of surplus public revenue to the people by means of a basic income or citizen's dividend. (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. Scholars disagree on the surprisingly subtle question of whether it was Say who first stated what is now called Say's law. 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, historically the first business school to be established. (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...) -
