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...)

Paul Robin Krugman (/ˈkrʊɡmən/ ⓘ KRUUG-mən; born February 28, 1953) is an American New Keynesian economist who is the Distinguished Professor of Economics at the Graduate Center of the City University of New York. He was a columnist for The New York Times from 2000 to 2024. 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 which he retired from in June 2015, holding the title of professor emeritus there ever since. 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. (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...) -

The Austrian school is a heterodox school of economic thought that advocates strict adherence to methodological individualism, the concept that social phenomena result primarily from the motivations and actions of individuals along with their self interest. Austrian-school theorists hold that economic theory should be exclusively derived from basic principles of human action.
The Austrian school originated in 1871 in Vienna with the work of Carl Menger, Eugen von Böhm-Bawerk, Friedrich von Wieser, and others. It was methodologically opposed to the Historical school, in a dispute known as Methodenstreit, or methodology quarrel. Current-day economists working in this tradition are located in many countries, but their work is still referred to as Austrian economics. Among the theoretical contributions of the early years of the Austrian school are the subjective theory of value, marginalism in price theory and the formulation of the economic calculation problem.

Classical economics, also known as the classical school of economics, or classical political economy, is a school of thought in political economy that flourished, primarily in Britain, in the late 18th and early-to-mid 19th century. It includes both the Smithian and Ricardian schools. Its main thinkers are held to be Adam Smith, Jean-Baptiste Say, David Ricardo, Thomas Robert Malthus, and John Stuart Mill. These economists produced a theory of market economies as largely self-regulating systems, governed by natural laws of production and exchange (famously captured by Adam Smith's metaphor of the invisible hand).
Adam Smith's The Wealth of Nations in 1776 is usually considered to mark the beginning of classical economics. The fundamental message in Smith's book was that the wealth of any nation was determined not by the gold in the monarch's coffers, but by its national income. This income was in turn based on the labor of its inhabitants, organized efficiently by the division of labour and the use of accumulated capital, which became one of classical economics' central concepts.

Tjalling Charles Koopmans (August 28, 1910 – February 26, 1985) was a Dutch-American mathematician and economist. He was the joint winner with Leonid Kantorovich of the 1975 Nobel Memorial Prize in Economic Sciences for his work on the theory of the optimum allocation of resources. Koopmans showed that on the basis of certain efficiency criteria, it is possible to make important deductions concerning optimum price systems. (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.

The first issue of Ms. magazine examined feminist economics in a piece by Jane O'Reilly
Feminist economics is the critical study of economics and economies, with a focus on gender-aware and inclusive economic inquiry and policy analysis. Feminist economic researchers include academics, activists, policy theorists, and practitioners. Much feminist economic research focuses on topics that have been neglected in the field, such as care work, intimate partner violence, or on economic theories which could be improved through better incorporation of gendered effects and interactions, such as between paid and unpaid sectors of economies. Other feminist scholars have engaged in new forms of data collection and measurement such as the Gender Empowerment Measure (GEM), and more gender-aware theories such as the capabilities approach. Feminist economics is oriented toward the social ecology of money.
Feminist economists call attention to the social constructions of traditional economics, questioning the extent to which it is positive and objective, and showing how its models and methods are biased by an exclusive attention to masculine-associated topics and a one-sided favoring of masculine-associated assumptions and methods. While economics traditionally focused on markets and masculine-associated ideas of autonomy, abstraction and logic, feminist economists call for a fuller exploration of economic life, including such "culturally feminine" topics such as family economics, and examining the importance of connections, concreteness, and emotion in explaining economic phenomena.

Disequilibrium macroeconomics is a tradition of research centered on the role of deviation from equilibrium 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. Other approaches that focus on the dynamic processes and interactions in economic systems that are constantly changing and do not necessarily settle into a stable state are discussed as non-equilibrium economics.

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...) -
Evolutionary economics is a school of economic thought that is inspired by evolutionary biology. Although not defined by a strict set of principles and uniting various approaches, it treats economic development as a process rather than an equilibrium and emphasizes change (qualitative, organisational, and structural), innovation, complex interdependencies, self-evolving systems, and limited rationality as the drivers of economic evolution. The support for the evolutionary approach to economics in recent decades seems to have initially emerged as a criticism of the mainstream neoclassical economics, but by the beginning of the 21st century it had become part of the economic mainstream itself.
Evolutionary economics does not take the characteristics of either the objects of choice or of the decision-maker as fixed. Rather, it focuses on the non-equilibrium processes that transform the economy from within and their implications, considering interdependencies and feedback. The processes in turn emerge from the actions of diverse agents with bounded rationality who may learn from experience and interactions and whose differences contribute to the change.

Thomas Piketty (French: [tɔmɑ pikɛti]; born 7 May 1971) is a French economist who is a professor of economics at the School for Advanced Studies in the Social Sciences, associate chair at the Paris School of Economics (PSE) and Centennial Professor of Economics in the International Inequalities Institute at the London School of Economics (LSE).
Piketty's work focuses on public economics, in particular income and wealth inequality. He is the author of the best-selling book Capital in the Twenty-First Century (2013), which emphasises the themes of his work on wealth concentrations and distribution over the past 250 years. The book argues that the rate of capital return in developed countries is persistently greater than the rate of economic growth, and that this will cause wealth inequality to increase in the future. Piketty proposes improving the education systems and considers diffusion of knowledge, diffusion of skills, diffusion of idea of productivity as the main mechanism that will lead to lower inequality. In 2019, his book Capital and Ideology was published, which focuses on income inequality in various societies in history. His 2022 A Brief History of Equality is a much shorter book about wealth redistribution intended for a target audience of citizens instead of economists. (Full article...) -
Thermoeconomics, also referred to as biophysical economics, is a school of heterodox economics that applies the laws of statistical mechanics to economic theory. Thermoeconomics can be thought of as the statistical physics of economic value and is a subfield of econophysics.
It is the study of the ways and means by which human societies procure and use energy and other biological and physical resources to produce, distribute, consume and exchange goods and services, while generating various types of waste and environmental impacts. Biophysical economics builds on both social sciences and natural sciences to overcome some of the most fundamental limitations and blind spots of conventional economics. It makes it possible to understand some key requirements and framework conditions for economic growth, as well as related constraints and boundaries. (Full article...) -
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...) -
Paul Anthony Samuelson (May 15, 1915 – December 13, 2009) was an American economist who was the first American to win the Nobel Memorial Prize in Economic Sciences. When awarding the prize in 1970, the Swedish Royal Academies stated that he "has done more than any other contemporary economist to raise the level of scientific analysis in economic theory".
Samuelson was one of the most influential economists of the latter half of the 20th century. In 1996, he was awarded the National Medal of Science. Samuelson considered mathematics to be the "natural language" for economists and contributed significantly to the mathematical foundations of economics with his book Foundations of Economic Analysis. He was author of the best-selling economics textbook of all time: Economics: An Introductory Analysis, first published in 1948. It was the second American textbook that attempted to explain the principles of Keynesian economics. (Full article...) -
Carl Menger von Wolfensgrün (/ˈmɛŋɡər/; German: [ˈmɛŋɐ]; 28 February 1840 – 26 February 1921) was an Austrian economist who contributed to the marginal theory of value. Menger is considered the founder of the Austrian school of economics.
In building his marginalist approach, Menger rejected many established views of classical economics. He directly disputed the view of the "German school" that economic theory could be derived from history. Departing from the cost-of-production theory of value—the prevailing theory of Adam Smith, David Ricardo, and Karl Marx—Menger's subjective theory of value emphasized role of mutual agreement in deriving prices. Although he had few readers outside Vienna until late in his career, disciples including Eugen von Böhm-Bawerk and Friedrich von Wieser brought his theories into wider readership. Friedrich Hayek wrote that the Austrian school's "fundamental ideas belong fully and wholly to Carl Menger." (Full article...) -
Keynesian economics (/ˈkeɪnziən/ KAYN-zee-ən; sometimes Keynesianism, named after British economist John Maynard Keynes) are the various macroeconomic theories and models of how aggregate demand (total spending in the economy) strongly influences economic output and inflation. In the Keynesian view, aggregate demand does not necessarily equal the productive capacity of the economy. It is influenced by a host of factors that sometimes behave erratically and impact production, employment, and inflation.
Keynesian economists generally argue that aggregate demand is volatile and unstable and that, consequently, a market economy often experiences inefficient macroeconomic outcomes, including recessions when demand is too low and inflation when demand is too high. Further, they argue that these economic fluctuations can be mitigated by economic policy responses coordinated between a government and their central bank. In particular, fiscal policy actions taken by the government and monetary policy actions taken by the central bank, can help stabilize economic output, inflation, and unemployment over the business cycle. Keynesian economists generally advocate a regulated market economy – predominantly private sector, but with an active role for government intervention during recessions and depressions.

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.

Anarchism is a political philosophy and movement that seeks to abolish all institutions that perpetuate authority, coercion, or hierarchy, primarily targeting the state and capitalism. Anarchism advocates for the replacement of the state with stateless societies and voluntary free associations. A historically left-wing movement, anarchism is usually described as the libertarian wing of the socialist movement (libertarian socialism).
Although traces of anarchist ideas are found all throughout history, modern anarchism emerged from the Enlightenment. During the latter half of the 19th and the first decades of the 20th century, the anarchist movement flourished in most parts of the world and had a significant role in workers' struggles for emancipation. Various anarchist schools of thought formed during this period. Anarchists have taken part in several revolutions, most notably in the Paris Commune, the Russian Civil War and the Spanish Civil War, whose end marked the end of the classical era of anarchism. In the last decades of the 20th and into the 21st century, the anarchist movement has been resurgent once more, growing in popularity and influence within anti-capitalist, anti-war and anti-globalisation movements.

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...) -
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...) -
Richer countries tend to be happier than poorer countries (observations are lined up around an upward-sloping trend), and richer people within countries tend to be happier than poorer people in the same countries (arrows are consistently pointing northeast).
The economics of happiness or happiness economics is the theoretical, qualitative and quantitative study of happiness and quality of life, including positive and negative affects, well-being, life satisfaction and related concepts – typically tying economics more closely than usual with other social sciences, like sociology and psychology, as well as physical health. It typically treats subjective happiness-related measures, as well as more objective quality of life indices, rather than wealth, income or profit, as something to be maximized.
The field has grown substantially since the late 20th century, for example by the development of methods, surveys and indices to measure happiness and related concepts, as well as quality of life. Happiness findings have been described as a challenge to the theory and practice of economics. Nevertheless, furthering gross national happiness, as well as a specified Index to measure it, has been adopted explicitly in the Constitution of Bhutan in 2008, to guide its economic governance.

Joseph Alois Schumpeter (German: [ˈʃʊmpeːtɐ]; February 8, 1883 – January 8, 1950) was an Austrian political economist. He served briefly as Finance Minister of Austria in 1919. In 1932, he emigrated to the United States to become a professor at Harvard University, where he remained until the end of his career, and in 1939 obtained American citizenship.
Schumpeter was one of the most influential economists of the early 20th century, and popularized the term "creative destruction", coined by Werner Sombart. His magnum opus is considered Capitalism, Socialism and Democracy. (Full article...) -
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...)
