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...)

Production and national income: Macroeconomics takes a big-picture view of the entire economy, including examining the roles of, and relationships between, firms, households and governments, and the different types of markets, such as the financial market and the labour market.
Macroeconomics is a branch of economics that deals with the performance, structure, behavior, and decision-making of an economy as a whole. This includes regional, national, and global economies. Macroeconomists study topics such as output/GDP (gross domestic product) and national income, unemployment (including unemployment rates), price indices and inflation, consumption, saving, investment, energy, international trade, and international finance.
Macroeconomics and microeconomics are the two most general fields in economics. The focus of macroeconomics is often on a country (or larger entities like the whole world) and how its markets interact to produce large-scale phenomena that economists refer to as aggregate variables. In microeconomics, the focus of analysis is often a single market, such as whether changes in supply or demand are to blame for price increases in the oil and automotive sectors.
From introductory classes in "principles of economics" through doctoral studies, the macro/micro divide is institutionalized in the field of economics. Most economists identify as either macro- or micro-economists. (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.

Jan Tinbergen (/ˈtɪnbɜːrɡən/ TIN-bur-gən, Dutch: [jɑn ˈtɪmbɛrɣə(n)]; 12 April 1903 – 9 June 1994) was a Dutch economist who was awarded the first Nobel Memorial Prize in Economic Sciences in 1969, which he shared with Ragnar Frisch for having developed and applied dynamic models for the analysis of economic processes. He is widely considered to be one of the most influential economists of the 20th century and one of the founding fathers of econometrics.
His important contributions to econometrics include the development of the first macroeconometric models, the solution of the identification problem, and the understanding of dynamic models. Tinbergen was a founding trustee of Economists for Peace and Security. In 1945, he founded the Bureau for Economic Policy Analysis (CPB) and was the agency's first director. (Full article...) -
Amartya Kumar Sen (Bengali: [ˈɔmortːo ˈʃen]; born 3 November 1933) is an Indian American economist and philosopher. Sen has taught and worked in England and the United States since 1972. In 1998, Sen received the Nobel Prize in Economic Sciences for his contributions to welfare economics. He has also made major scholarly contributions to social choice theory, economic and social justice, economic theories of famines, decision theory, development economics, public health, and the measures of well-being of countries.
Sen is currently the Thomas W. Lamont University Professor, and Professor of Economics and Philosophy, at Harvard University. He previously served as Master of Trinity College at the University of Cambridge. In 1999, he received India's highest civilian honour, Bharat Ratna, for his contribution to welfare economics. The German Publishers and Booksellers Association awarded him the 2020 Peace Prize of the German Book Trade for his pioneering scholarship addressing issues of global justice and combating social inequality in education and healthcare.

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...) -

Gary Stanley Becker (/ˈbɛkər/; December 2, 1930 – May 3, 2014) was an American economist who received the 1992 Nobel Memorial Prize in Economic Sciences. He was a professor of economics and sociology at the University of Chicago, and was a leader of the third generation of the Chicago school of economics.
Becker was awarded the Nobel Memorial Prize in Economic Sciences in 1992 and received the United States Presidential Medal of Freedom in 2007. A 2011 survey of economics professors named Becker their favorite living economist over the age of 60, followed by Kenneth Arrow and Robert Solow. Economist Justin Wolfers called him "the most important social scientist in the past 50 years." (Full article...) -
The American School, also known as the National System, represents three different yet related constructs in politics, policy and philosophy. The policy existed from the 1790s to the 1970s, waxing and waning in actual degrees and details of implementation. Historian Michael Lind describes it as a coherent applied economic philosophy with logical and conceptual relationships with other economic ideas.
It is the macroeconomic philosophy that dominated United States national policies from the time of the American Civil War until the mid-20th century. Closely related to mercantilism, it can be seen as contrary to classical economics. It consisted of these three core policies:- Protecting industry through selective high tariffs (especially 1861–1932).
- Government investments in infrastructure creating targeted internal improvements (especially in transportation).
- A national bank with policies that promote the growth of productive enterprises rather than speculation.

Hermann Heinrich Gossen (7 September 1810 – 13 February 1858) was a German economist who is often regarded as the first to elaborate, in detail, a general theory of marginal utility.
Prior to Gossen, a number of economic theorists, including Gabriel Cramer, Daniel Bernoulli, William Forster Lloyd, Nassau William Senior, and Jules Dupuit had employed or asserted the significance of some notion of marginal utility. But Cramer, Bernoulli, and Dupuit had focussed upon specific problems, Lloyd had not presented any applications of theory, and if Senior provided a detailed elaboration of the general theory he had developed, he had done so in language that caused his applications of theory to be missed by most readers.

John Bates Clark (January 26, 1847 – March 21, 1938) was an American neoclassical economist. He was one of the pioneers of the marginalist revolution and opponent to the Institutionalist school of economics, and spent most of his career as a professor at Columbia University. He was one of the most prominent American economists of his time. (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...) -

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...) -
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 creative destruction, a term coined by Werner Sombart. His magnum opus is considered to be Capitalism, Socialism and Democracy. (Full article...) -

Decision theory or the theory of rational choice is a branch of probability, economics, and analytic philosophy that uses expected utility and probability to model how individuals would behave rationally under uncertainty. It differs from the cognitive and behavioral sciences in that it is mainly prescriptive and concerned with identifying optimal decisions for a rational agent, rather than describing how people actually make decisions. Despite this, the field is important to the study of real human behavior by social scientists, as it lays the foundations to mathematically model and analyze individuals in fields such as sociology, economics, criminology, cognitive science, moral philosophy and political science.

Friedrich August von Hayek (8 May 1899 – 23 March 1992) was an Austrian-born British economist 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.

Vilfredo Federico Damaso Pareto (/pəˈreɪtoʊ/; Italian: [paˈreːto]; 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, and was one of the minds behind the Lausanne School of economics. He was also responsible for popularising the use of the term elite in social analysis and contributed to elite theory. He has been described as "one of the last Renaissance scholars. Trained in physics and mathematics, he became a polymath whose genius radiated into nearly all other major fields of knowledge."
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 mathematics and sociology. (Full article...) -
Herbert Alexander Simon (June 15, 1916 – February 9, 2001) was an American scholar whose work 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 Turing Award in 1975 and the Nobel Memorial Prize in Economic Sciences in 1978. 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...) -
Economic democracy (sometimes called a democratic economy) is a socioeconomic philosophy that proposes to shift ownership and decision-making power from corporate shareholders and corporate managers (such as a board of directors) to a larger group of public stakeholders that includes workers, consumers, suppliers, communities and the broader public. No single definition or approach encompasses economic democracy, but most proponents claim that modern property relations externalize costs, subordinate the general well-being to private profit and deny the polity a democratic voice in economic policy decisions. In addition to these moral concerns, economic democracy makes practical claims, such as that it can compensate for capitalism's inherent effective demand gap.
Proponents of economic democracy generally argue that modern capitalism periodically results in economic crises, characterized by deficiency of effective demand; as society is unable to earn enough income to purchase its own production output. Corporate monopoly of common resources typically creates artificial scarcity, resulting in socio-economic imbalances that restrict workers from access to economic opportunity and diminish consumer purchasing power. Economic democracy has been proposed as a component of larger socioeconomic ideologies, as a stand-alone theory and as a variety of reform agendas. For example, as a means to securing full economic rights, it opens a path to full political rights, defined as including the former. Both market and non-market theories of economic democracy have been proposed. As a reform agenda, supporting theories and real-world examples can include decentralization, democratic cooperatives, public banking, fair trade and the regionalization of food production and currency.

Ludwig Heinrich Edler von Mises (/vɒn ˈmiːzɪz/; German: [ˈluːtvɪç fɔn ˈmiːzəs]; September 29, 1881 – October 10, 1973) was an Austrian and American political economist and philosopher of the Austrian school. Mises wrote and lectured extensively on the social contributions of classical liberalism and the central role of consumers in a market economy. He is best known for his work in praxeology, particularly for studies comparing communism and capitalism, as well as for being a defender of classical liberalism in the face of rising illiberalism and authoritarianism throughout much of Europe during the 20th century.
In 1934, Mises fled from Austria to Switzerland to escape the Nazis and he emigrated from there to the United States in 1940. On the day German forces entered Vienna, they raided his apartment, confiscating his papers and library, which were believed lost or destroyed until rediscovered decades later in Soviet archives. At the time, Mises was living in Geneva, Switzerland. However, with the imminent Nazi occupation of France threatening to isolate Switzerland within Axis-controlled territory, he and his wife fled through France—avoiding German patrols—and reached the United States via Spain and Portugal.

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.

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.

Irving Fisher (February 27, 1867 – April 29, 1947) was an American economist, statistician, inventor, eugenicist and progressive social campaigner. He was one of the earliest American neoclassical economists, though his later work on debt deflation has been embraced by the post-Keynesian school. Joseph Schumpeter described him as "the greatest economist the United States has ever produced", an assessment later repeated by James Tobin and Milton Friedman.
Fisher made important contributions to utility theory and general equilibrium. He was also a pioneer in the rigorous study of intertemporal choice in markets, which led him to develop a theory of capital and interest rates. His research on the quantity theory of money inaugurated the school of macroeconomic thought known as "monetarism". Fisher was also a pioneer of econometrics, including the development of index numbers. Some concepts named after him include the Fisher equation, the Fisher hypothesis, the international Fisher effect, the Fisher separation theorem and Fisher market. (Full article...)
