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...)

  von Neumann in the 1940s

  
  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...)

  Lucas in 1996

  
  Robert Emerson Lucas Jr. (September 15, 1937 – May 15, 2023) was an American economist at the University of Chicago. Widely regarded as the central figure in the development of the new classical approach to macroeconomics, he received the Nobel Memorial Prize in Economic Sciences in 1995 "for having developed and applied the hypothesis of rational expectations, and thereby having transformed macroeconomic analysis and deepened our understanding of economic policy". N. Gregory Mankiw characterized him as "the most influential macroeconomist of the last quarter of the 20th century". In 2020, he ranked as the 10th most cited economist in the world.

  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.

  Econometrics is an application of statistical methods to economic data in order to give empirical content to economic relationships. More precisely, it is "the quantitative analysis of actual economic phenomena based on the concurrent development of theory and observation, related by appropriate methods of inference." An introductory economics textbook describes econometrics as allowing economists "to sift through mountains of data to extract simple relationships." Jan Tinbergen is one of the two founding fathers of econometrics. The other, Ragnar Frisch, also coined the term in the sense in which it is used today.
  
  A basic tool for econometrics is the multiple linear regression model. Econometric theory uses statistical theory and mathematical statistics to evaluate and develop econometric methods. Econometricians try to find estimators that have desirable statistical properties including unbiasedness, efficiency, and consistency. Applied econometrics uses theoretical econometrics and real-world data for assessing economic theories, developing econometric models, analysing economic history, and forecasting. (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...)

  Carl Menger von Wolfensgrün, founder of the Austrian school

  
  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...)

  Monetary circuit theory is a heterodox theory of monetary economics, particularly money creation, often associated with the post-Keynesian school.
  It holds that money is created endogenously by the banking sector, rather than exogenously by central bank lending; it is a theory of endogenous money. It is also called circuitism and the circulation approach. (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, flawed 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...)

  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...)

  The Chicago school of economics is a neoclassical school of economic thought associated with the work of the faculty at the University of Chicago, some of whom have constructed and popularized its principles. Milton Friedman and George Stigler are considered the leading scholars of the Chicago school.
  
  Chicago macroeconomic theory 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. The freshwater–saltwater distinction is largely antiquated today, as the two traditions have heavily incorporated ideas from each other. Specifically, new Keynesian economics was developed as a response to new classical economics, electing to incorporate the insight of rational expectations without giving up the traditional Keynesian focus on imperfect competition and sticky wages.

  Keynes in 1929

  
  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. After the 1929 crisis, Keynes also turned away from a fundamental pillar of neoclassical economics: free trade. He criticized Ricardian comparative advantage theory (the foundation of free trade), considering the theory's initial assumptions unrealistic, and became definitively protectionist. 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.

  Polanyi, c. 1918

  
  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...)

  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.

  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...)

  Slogan in Bhutan about gross national happiness in Thimphu's School of Traditional Arts.

  
  Buddhist economics is a spiritual and philosophical approach to the study of economics. It examines the psychology of the human mind and the emotions that direct economic activity, in particular concepts such as anxiety, aspirations and self-actualization principles. In the view of its proponents, Buddhist economics aims to clear the confusion about what is harmful and what is beneficial in the range of human activities involving the production and consumption of goods and services, ultimately trying to make human beings ethically mature. The ideology's stated purpose is to "find a middle way between a purely mundane society and an immobile, conventional society."
  
  The most fundamental feature of Buddhist economics is seeing "people interdependent with one another and with Nature." (Full article...)

  Wilhelm Röpke

  
  Wilhelm Röpke (German: [ˈʁœpkə]; 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...)

  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.

  Oskar Lange

  
  Oskar Ryszard Lange (Polish: [ˈlanɡɛ]; 27 July 1904 – 2 October 1965) was a Polish economist and diplomat. He is best known for advocating the use of market pricing tools in socialist systems and providing a model of market socialism. He responded to the economic calculation problem proposed by Ludwig von Mises and Friedrich Hayek by claiming that managers in a centrally-planned economy would be able to monitor supply and demand through increases and declines in inventories of goods, and advocated the nationalization of major industries. During his stay in the United States, Lange was an academic teacher and researcher in mathematical economics. Later in socialist Poland, he was a member of the Central Committee of the Polish United Workers' Party. (Full article...)

  François Quesnay (/keɪˈneɪ/; 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...)

  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.
