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 factors affecting it: factors of production, such as labour, capital, land, and enterprise, inflation, economic growth, and public policies that have impact on these elements. It also seeks to analyse and describe the global economy. (Full article...)

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...) -
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...) -
Ecological economics, bioeconomics, ecolonomy, eco-economics, or ecol-econ is both a transdisciplinary and an interdisciplinary field of academic research addressing the interdependence and coevolution of human economies and natural ecosystems, both intertemporally and spatially. By treating the economy as a subsystem of Earth's larger ecosystem, and by emphasizing the preservation of natural capital, the field of ecological economics is differentiated from environmental economics, which is the mainstream economic analysis of the environment. One survey of German economists found that ecological and environmental economics are different schools of economic thought, with ecological economists emphasizing strong sustainability and rejecting the proposition that physical (human-made) capital can substitute for natural capital (see the section on weak versus strong sustainability below).
Ecological economics was founded in the 1980s as a modern discipline on the works of and interactions between various European and American academics (see the section on History and development below). The related field of green economics is in general a more politically applied form of the subject. (Full article...) -
Vilfredo Federico Damaso Pareto (born Wilfried Fritz Pareto; 15 July 1848 – 19 August 1923) was an Italian polymath, whose areas of interest included sociology, civil engineering, economics, political science, and philosophy. He made several important contributions to economics, particularly in the study of income distribution and in the analysis of individuals' choices. He was also responsible for popularising the use of the term elite in social analysis.
He introduced the concept of Pareto efficiency and helped develop the field of microeconomics. He was also the first to claim that income follows a Pareto distribution, which is a power law probability distribution. The Pareto principle was named after him, and it was built on his observations that 80% of the wealth in Italy belonged to about 20% of the population. He also contributed to the fields of sociology and mathematics. (Full article...) -
Ludwig Heinrich Edler von Mises (German: [ˈluːtvɪç fɔn ˈmiːzəs]; 29 September 1881 – 10 October 1973) was an Austrian-American economist, logician, sociologist and philosopher of economics of the Austrian school. Mises wrote and lectured extensively on the societal contributions of classical liberalism and the power of consumers. 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.
Mises emigrated from Austria to the United States in 1940, fleeing from Nazis who on the first day the German Army entered Vienna rushed into the von Mises apartment in Vienna, apparently looking for him, and confiscated his library and papers. Mises was in Geneva, Switzerland at the time, but when the German invasion of France was about to leave Switzerland completely surrounded by Fascist and Nazi controlled territory, von Mises and his wife found it necessary to flee through France dodging German troops, to get to the US via Spain and Portugal. Since the mid-20th century, both libertarian movements and the field of economics as a whole, have been strongly influenced by Mises's writings. Mises's student Friedrich Hayek viewed Mises as one of the major figures in the revival of classical liberalism in the post-war era. Hayek's work The Transmission of the Ideals of Freedom (1951) pays high tribute to the influence of Mises in the 20th-century libertarian movement. Economist Tyler Cowen lists his writings as "the most important works of the 20th century" and as "among the most important economics articles, ever". (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.

John Stuart Mill (20 May 1806 – 7 May 1873) was an English philosopher, political economist, politician and civil servant. One of the most influential thinkers in the history of liberalism, he contributed widely to social theory, political theory, and political economy. Dubbed "the most influential English-speaking philosopher of the nineteenth century" by the Stanford Encyclopedia of Philosophy, he conceived of liberty as justifying the freedom of the individual in opposition to unlimited state and social control. He advocated political and social reforms such as proportional representation, the emancipation of women, and the development of labour organisations and farm cooperatives. The Columbia Encyclopedia 5th ed. says of him "at times Mill came close to socialism, a theory repugnant to his predecessors." He was a proponent of utilitarianism, an ethical theory developed by his predecessor Jeremy Bentham. He contributed to the investigation of scientific methodology, though his knowledge of the topic was based on the writings of others, notably William Whewell, John Herschel, and Auguste Comte, and research carried out for Mill by Alexander Bain. He engaged in written debate with Whewell.
A member of the Liberal Party and author of the early feminist work The Subjection of Women, Mill was also the second member of Parliament to call for women's suffrage after Henry Hunt in 1832. (Full article...) -
Eugen Ritter von Böhm-Bawerk (German: [bøːm ˈbaːvɛʁk]; born Eugen Böhm, 12 February 1851 – 27 August 1914) was an economist from Austria-Hungary who made important contributions to the development of macroeconomics and to the Austrian School of Economics. He served intermittently as the Austrian Minister of Finance between 1895 and 1904. He is also noted for writing extensive criticisms of Marxism. (Full article...) -
Jean-Baptiste Say (French: [ʒɑ̃batist sɛ]; 5 January 1767 – 15 November 1832) was a liberal French economist and businessman who argued in favor of competition, free trade and lifting restraints on business. He is best known for Say's law—also known as the law of markets—which he popularized, although scholars disagree as to whether it was Say who first articulated the theory. Moreover, he was one of the first economists to study entrepreneurship and conceptualized entrepreneurs as organizers and leaders of the economy. He was also closely involved in the development of the École spéciale de commerce et d'industrie (ESCP), historically the first business school to be established. (Full article...) -
Neoclassical economics is an approach to economics in which the production, consumption, and valuation (pricing) of goods and services are observed as driven by the supply and demand model. According to this line of thought, the value of a good or service is determined through a hypothetical maximization of utility by income-constrained individuals and of profits by firms facing production costs and employing available information and factors of production. This approach has often been justified by appealing to rational choice theory.
Neoclassical economics is the dominant approach to microeconomics and, together with Keynesian economics, formed the neoclassical synthesis which dominated mainstream economics as "neo-Keynesian economics" from the 1950s onward. (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 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 (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...) -
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...) -
William Stanley Jevons FRS (/ˈdʒɛvənz/; 1 September 1835 – 13 August 1882) was an English economist and logician.
Irving Fisher described Jevons's book A General Mathematical Theory of Political Economy (1862) as the start of the mathematical method in economics. It made the case that economics, as a science concerned with quantities, is necessarily mathematical. In so doing, it expounded upon the "final" (marginal) utility theory of value. Jevons' work, along with similar discoveries made by Carl Menger in Vienna (1871) and by Léon Walras in Switzerland (1874), marked the opening of a new period in the history of economic thought. Jevons's contribution to the marginal revolution in economics in the late 19th century established his reputation as a leading political economist and logician of the time. (Full article...) -
Carl Menger von Wolfensgrün (/ˈmɛŋɡər/; German: [ˈmɛŋɐ]; 28 February 1840 – 26 February 1921) was an Austrian economist and the founder of the Austrian school of economics. Menger contributed to the development of the theories of marginalism and marginal utility, which rejected cost-of-production theory of value, such as developed by the classical economists such as Adam Smith and David Ricardo. As a departure from such, he would go on to call his resultant perspective, the subjective theory of value. (Full article...) -
John Maynard Keynes, 1st Baron Keynes CB, FBA (/keɪnz/ KAYNZ; 5 June 1883 – 21 April 1946), was an English economist and philosopher whose ideas fundamentally changed the theory and practice of macroeconomics and the economic policies of governments. Originally trained in mathematics, he built on and greatly refined earlier work on the causes of business cycles. One of the most influential economists of the 20th century, he produced writings that are the basis for the school of thought known as Keynesian economics, and its various offshoots. His ideas, reformulated as New Keynesianism, are fundamental to mainstream macroeconomics. He is known as the "father of macroeconomics".
During the Great Depression of the 1930s, Keynes spearheaded a revolution in economic thinking, challenging the ideas of neoclassical economics that held that free markets would, in the short to medium term, automatically provide full employment, as long as workers were flexible in their wage demands. He argued that aggregate demand (total spending in the economy) determined the overall level of economic activity, and that inadequate aggregate demand could lead to prolonged periods of high unemployment, and since wages and labour costs are rigid downwards the economy will not automatically rebound to full employment. Keynes advocated the use of fiscal and monetary policies to mitigate the adverse effects of economic recessions and depressions. 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.

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.

Thorstein Bunde Veblen (July 30, 1857 – August 3, 1929) was an American economist and sociologist who, during his lifetime, emerged as a well-known critic of capitalism.
In his best-known book, The Theory of the Leisure Class (1899), Veblen coined the concepts of conspicuous consumption and conspicuous leisure. Veblen laid the foundation for the perspective of the institutional economics. Contemporary economists still theorize Veblen's distinction between "institutions" and "technology", known as the Veblenian dichotomy. (Full article...) -
Elinor Claire "Lin" Ostrom (née Awan; August 7, 1933 – June 12, 2012) was an American political scientist and political economist whose work was associated with New Institutional Economics and the resurgence of political economy. In 2009, she was awarded the Nobel Memorial Prize in Economic Sciences for her "analysis of economic governance, especially the commons", which she shared with Oliver E. Williamson; she was the first woman to win the prize.
Trained in political science at UCLA, Ostrom was a faculty member at Indiana University in Bloomington for 47 years. Beginning in the 1960s, Ostrom was involved in resource management policy and created a research center, the Workshop in Political Theory and Policy Analysis, which attracted scientists from different disciplines from around the world. Working and teaching at her center was created on the principle of a workshop, rather than a university with lectures and a strict hierarchy. Late in her career, she held an affiliation with Arizona State University. (Full article...) -
François Quesnay (French: [fʁɑ̃swa kɛnɛ]; 4 June 1694 – 16 December 1774) was a French economist and physician of the Physiocratic school. He is known for publishing the "Tableau économique" (Economic Table) in 1758, which provided the foundations of the ideas of the Physiocrats. This was perhaps the first work attempting to describe the workings of the economy in an analytical way, and as such can be viewed as one of the first important contributions to economic thought. His Le Despotisme de la Chine, written in 1767, describes Chinese politics and society, and his own political support for enlightened despotism. (Full article...) -
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).
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...) -
Daniel Friedrich List (6 August 1789 – 30 November 1846) was a German entrepreneur, diplomat, economist and political theorist who developed the nationalist theory of political economy in both Europe and the United States. He was a forefather of the German historical school of economics and argued for the Zollverein (a pan-German customs union) from a nationalist standpoint. He advocated raising tariffs on imported goods while supporting free trade of domestic goods and stated the cost of a tariff should be seen as an investment in a nation's future productivity. His theories and writing also influenced the American school of economics.
List was a political liberal who collaborated with Karl von Rotteck and Carl Theodor Welcker on the Rotteck-Welckersches Staatslexikon, an encyclopedia of political science that advocated constitutional liberalism and which influenced the Vormärz. At the time in Europe, liberal and nationalist ideas were almost inseparably linked, and political liberalism was not yet attached to what was later considered "economic liberalism." Emmanuel Todd considers List a forerunner to John Maynard Keynes as a theorist of "moderate or regulated capitalism." (Full article...) -
Marginalism is a theory of economics that attempts to explain the discrepancy in the value of goods and services by reference to their secondary, or marginal, utility. It states that the reason why the price of diamonds is higher than that of water, for example, owes to the greater additional satisfaction of the diamonds over the water. Thus, while the water has greater total utility, the diamond has greater marginal utility.
Although the central concept of marginalism is that of marginal utility, marginalists, following the lead of Alfred Marshall, drew upon the idea of marginal physical productivity in explanation of cost. The neoclassical tradition that emerged from British marginalism abandoned the concept of utility and gave marginal rates of substitution a more fundamental role in analysis. Marginalism is an integral part of mainstream economic theory. (Full article...) -
Friedrich August von Hayek CH FBA (/ˈhaɪək/ HY-ək, German: [ˈfʁiːdʁɪç ˈʔaʊɡʊst fɔn ˈhaɪɛk] ; 8 May 1899 – 23 March 1992), often referred to by his initials F. A. Hayek, was an Austrian-born British academic who contributed 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.

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...)
