Introduction
Economics (/ˌɛkəˈnɒmɪks, ˌiːkə-/) is a behavioral 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...)

Sir John Richard Hicks (8 April 1904 – 20 May 1989) was a British economist. He is considered one of the most important and influential economists of the twentieth century. The most familiar of his many contributions in the field of economics were his statement of consumer demand theory in microeconomics, and the IS–LM model (1937), which summarised a Keynesian view of macroeconomics. His book Value and Capital (1939) significantly extended general-equilibrium and value theory. The compensated demand function is named the Hicksian demand function in memory of him.
In 1972 he received the Nobel Memorial Prize in Economic Sciences (jointly) for his pioneering contributions to general equilibrium theory and welfare theory. (Full article...) -
Mathematical economics is the application of mathematical methods to represent theories and analyze problems in economics. Often, these applied methods are beyond simple geometry, and may include differential and integral calculus, difference and differential equations, matrix algebra, mathematical programming, or other computational methods. Proponents of this approach claim that it allows the formulation of theoretical relationships with rigor, generality, and simplicity.
Mathematics allows economists to form meaningful, testable propositions about wide-ranging and complex subjects which could less easily be expressed informally. Further, the language of mathematics allows economists to make specific, positive claims about controversial or contentious subjects that would be impossible without mathematics. Much of economic theory is currently presented in terms of mathematical economic models, a set of stylized and simplified mathematical relationships asserted to clarify assumptions and implications.

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...) -
Computational economics is an interdisciplinary research discipline that combines methods in computational science and economics to solve complex economic problems, such as in the field Complexity Economics. 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 the following research discussions.
Econometrics: Non-parametric approaches, semi-parametric approaches, and machine learning. By dynamic systems modeling: Optimization, dynamic stochastic general equilibrium modeling, and agent-based modeling inside Complexity Economics. (Full article...) -
John von Neumann (/vɒn ˈnɔɪmən/ von NOY-mən; Hungarian: Neumann János Lajos [ˈnɒjmɒn ˈjaːnoʃ ˈlɒjoʃ]; December 28, 1903 – February 8, 1957) was a Hungarian and American mathematician, physicist, computer scientist and engineer. Von Neumann had perhaps the widest coverage of any mathematician of his time, integrating pure and applied sciences and making major contributions to many fields, including mathematics, physics, economics, computing, and statistics. He was a pioneer in building the mathematical framework of quantum physics, in the development of functional analysis, and in game theory, introducing or codifying concepts including cellular automata, the universal constructor and the digital computer. His analysis of the structure of self-replication preceded the discovery of the structure of DNA.
During World War II, von Neumann worked on the Manhattan Project. He developed the mathematical models behind the explosive lenses used in the implosion-type nuclear weapon. Before and after the war, he consulted for many organizations including the Office of Scientific Research and Development, the Army's Ballistic Research Laboratory, the Armed Forces Special Weapons Project and the Oak Ridge National Laboratory. At the peak of his influence in the 1950s, he chaired a number of Defense Department committees including the Strategic Missile Evaluation Committee and the ICBM Scientific Advisory Committee. He was also a member of the influential Atomic Energy Commission in charge of all atomic energy development in the country. He played a key role alongside Bernard Schriever and Trevor Gardner in the design and development of the United States' first ICBM programs. At that time he was considered the nation's foremost expert on nuclear weaponry and the leading defense scientist at the U.S. Department of Defense. (Full article...) -

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.

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.

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...) -
Robert Merton Solow, GCIH (/ˈsoʊloʊ/; August 23, 1924 – December 21, 2023) was an American economist who received the 1987 Nobel Memorial Prize in Economic Sciences, and whose work on the theory of economic growth culminated in the exogenous growth model named after him.
He was Institute Professor Emeritus of Economics at the Massachusetts Institute of Technology, where he was a professor from 1949 on. He was awarded the John Bates Clark Medal in 1961, the Nobel Memorial Prize in Economic Sciences in 1987, and the Presidential Medal of Freedom in 2014. Four of his PhD students, George Akerlof, Joseph Stiglitz, Peter Diamond, and William Nordhaus, later received Nobel Memorial Prizes in Economic Sciences in their own right. (Full article...) -
Institutional economics focuses on understanding the role of the evolutionary process and the role of institutions in shaping economic behavior. Its original focus lay in Thorstein Veblen's instinct-oriented dichotomy between technology on the one side and the "ceremonial" sphere of society on the other. Its name and core elements trace back to a 1919 American Economic Review article by Walton H. Hamilton. Institutional economics emphasizes a broader study of institutions and views markets as a result of the complex interaction of these various institutions (e.g. individuals, firms, states, social norms). The earlier tradition continues today as a leading heterodox approach to economics.
"Traditional" institutionalism rejects the reduction of institutions to simply tastes, technology, and nature (see naturalistic fallacy). Tastes, along with expectations of the future, habits, and motivations, not only determine the nature of institutions but are limited and shaped by them. If people live and work in institutions on a regular basis, it shapes their world views. Fundamentally, this traditional institutionalism (and its modern counterpart institutionalist political economy) emphasizes the legal foundations of an economy (see John R. Commons) and the evolutionary, habituated, and volitional processes by which institutions are erected and then changed (see John Dewey, Thorstein Veblen, and Daniel Bromley). Institutional economics focuses on learning, bounded rationality, and evolution (rather than assuming stable preferences, rationality and equilibrium). It was a central part of American economics in the first part of the 20th century, including such famous but diverse economists as Thorstein Veblen, Wesley Mitchell, and John R. Commons. Some institutionalists see Karl Marx as belonging to the institutionalist tradition, because he described capitalism as a historically bounded social system; other institutionalist economists[who?] disagree with Marx's definition of capitalism, instead seeing defining features such as markets, money and the private ownership of production as indeed evolving over time, but as a result of the purposive actions of individuals.

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.

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.

James McGill Buchanan Jr. (/bjuːˈkænən/ bew-KAN-ən; October 3, 1919 – January 9, 2013) was an American economist known for his work on public choice theory originally outlined in his most famous work, The Calculus of Consent, co-authored with Gordon Tullock in 1962. He continued to develop the theory, eventually receiving the Nobel Memorial Prize in Economic Sciences in 1986. Buchanan's work initiated research on how politicians' and bureaucrats' self-interest, utility maximization, and other non-wealth-maximizing considerations affect their decision-making. He was a member of the Board of Advisors of The Independent Institute as well as of the Institute of Economic Affairs, a member of the Mont Pelerin Society (MPS) and MPS president from 1984 to 1986, a Distinguished Senior Fellow of the Cato Institute, and professor at George Mason University.

A mixed economy is an economic system that includes both elements associated with capitalism, such as private businesses, and with socialism, such as nationalized government services.
More specifically, a mixed economy may be variously defined as an economic system blending elements of a market economy with elements of a planned economy, markets with state interventionism, or private enterprise with public enterprise. Common to all mixed economies is a combination of free-market principles and principles of socialism. (Full article...) -
The Lausanne School of economics, sometimes referred to as the Mathematical School, refers to the neoclassical economics school of thought surrounding Léon Walras and Vilfredo Pareto. It is named after the University of Lausanne, at which both Walras and Pareto held professorships. Polish economist Leon Winiarski is also said to have been a member of the Lausanne School.

Karl Paul Polanyi (/poʊˈlænji/; Hungarian: Polányi Károly [ˈpolaːɲi ˈkaːroj]; 25 October 1886 – 23 April 1964) was an Austro-Hungarian economic anthropologist, economic sociologist, and politician, best known for his book The Great Transformation, which questions the conceptual validity of self-regulating markets.
In his writings, Polanyi advances the concept of the Double Movement, which refers to the dialectical process of marketization and push for social protection against that marketization. He argues that market-based societies in modern Europe were not inevitable but historically contingent. Polanyi is remembered best as the originator of substantivism, a cultural version of economics, which emphasizes the way economies are embedded in society and culture. This opinion is counter to mainstream economics but is popular in anthropology, economic history, economic sociology and political science. (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 Marx (German: [ˈkaʁl ˈmaʁks]; 5 May 1818 – 14 March 1883) was a German philosopher, political theorist, economist, journalist, and revolutionary socialist. He is best-known for the 1848 pamphlet The Communist Manifesto (written with Friedrich Engels), and his three-volume Das Kapital (1867–1894), a critique of classical political economy which employs his theory of historical materialism in an analysis of capitalism, in the culmination of his life's work. Marx's ideas and their subsequent development, collectively known as Marxism, have had enormous influence.
Born in Trier in the Kingdom of Prussia, Marx studied at the universities of Bonn and Berlin, and received a doctorate in philosophy from the University of Jena in 1841. A Young Hegelian, he was influenced by the philosophy of Georg Wilhelm Friedrich Hegel, and both critiqued and developed Hegel's ideas in works such as The German Ideology (written 1846) and the Grundrisse (written 1857–1858). While in Paris, Marx wrote his Economic and Philosophic Manuscripts of 1844 and met Engels, who became his closest friend and collaborator. After moving to Brussels in 1845, they were active in the Communist League, and in 1848 they wrote The Communist Manifesto, which expresses Marx's ideas and lays out a programme for revolution. Marx was expelled from Belgium and Germany, and in 1849 moved to London, where he wrote The Eighteenth Brumaire of Louis Bonaparte (1852) and Das Kapital. From 1864, Marx was involved in the International Workingmen's Association (First International), in which he fought the influence of anarchists led by Mikhail Bakunin. In his Critique of the Gotha Programme (1875), Marx wrote on revolution, the state and the transition to communism. He died stateless in 1883 and was buried in Highgate Cemetery. (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, Thünen 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...) -
Alan Greenspan (born March 6, 1926) is an American economist who served as the 13th chairman of the Federal Reserve from 1987 to 2006. He worked as a private adviser and provided consulting for firms through his company, Greenspan Associates LLC.
First nominated to the Federal Reserve by President Ronald Reagan in August 1987, Greenspan was reappointed at successive four-year intervals until retiring on January 31, 2006, after the second-longest tenure in the position, behind only William McChesney Martin. President George W. Bush appointed Ben Bernanke as his successor.
Greenspan came to the Federal Reserve Board from a consulting career. Although he was subdued in his public appearances, favorable media coverage raised his profile to a point that several observers likened him to a "rock star". Democratic leaders of Congress criticized him for politicizing his office because of his support for Social Security privatization and tax cuts. (Full article...) -
Agent-based computational economics (ACE) is the area of computational economics that studies economic processes, including whole economies, as dynamic systems of interacting agents. As such, it falls in the paradigm of complex adaptive systems. In corresponding agent-based models, the "agents" are "computational objects modeled as interacting according to rules" over space and time, not real people. The rules are formulated to model behavior and social interactions based on incentives and information. Such rules could also be the result of optimization, realized through use of AI methods (such as Q-learning and other reinforcement learning techniques).
As part of non-equilibrium economics, the theoretical assumption of mathematical optimization by agents in equilibrium is replaced by the less restrictive postulate of agents with bounded rationality adapting to market forces. ACE models apply numerical methods of analysis to computer-based simulations of complex dynamic problems for which more conventional methods, such as theorem formulation, may not find ready use. Starting from initial conditions specified by the modeler, the computational economy evolves over time as its constituent agents repeatedly interact with each other, including learning from interactions. In these respects, ACE has been characterized as a bottom-up culture-dish approach to the study of economic systems. (Full article...) -
Thomas Sowell (/soʊl/ SOHL; born June 30, 1930) is an American economist, economic historian, and social 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 graduated magna cum laude from Harvard University in 1958. He earned a master's degree in economics from Columbia University the next year, and a PhD 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...) -
Knut Wicksell, Swedish economist. Important source of inspiration for John Maynard Keynes and the Stockholm School.
The Stockholm School (Swedish: Stockholmsskolan) is a school of economic thought. It refers to a loosely organized group of Swedish economists that worked together, in Stockholm, Sweden primarily in the 1930s.
The Stockholm School had—like John Maynard Keynes—come to the same conclusions in macroeconomics and the theories of demand and supply. Like Keynes, they were inspired by the works of Knut Wicksell, a Swedish economist active in the early years of the twentieth century. (Full article...) -

Friedrich August von Hayek CH FBA (8 May 1899 – 23 March 1992) was an Austrian-born British academic and philosopher. He is known for his contributions to political economy, political philosophy and intellectual history. Hayek shared the 1974 Nobel Memorial Prize in Economic Sciences with Gunnar Myrdal for work on money and economic fluctuations, and the interdependence of economic, social and institutional phenomena. His account of how prices communicate information is widely regarded as an important contribution to economics that led to him receiving the prize. He was a major contributor to the Austrian school of economics.
During his teenage years, Hayek fought in World War I. He later said this experience, coupled with his desire to help avoid the mistakes that led to the war, drew him into economics. He earned doctoral degrees in law in 1921 and political studies in 1923 from the University of Vienna. He subsequently lived and worked in Austria, Great Britain, the United States and Germany. He became a British national in 1938. He studied and taught at the London School of Economics and later at the University of Chicago, before returning to Europe late in life to teach at the Universities of Salzburg and Freiburg.
