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...)

Physiocracy (French: physiocratie; from the Greek for "government of nature") is an economic theory developed by a group of 18th-century Age of Enlightenment French economists who believed that the wealth of nations derived solely from the value of "land agriculture" or "land development" and that agricultural products should be highly priced. Their theories originated in France and were most popular during the second half of the 18th century. Physiocracy became one of the first well-developed theories of economics.
François Quesnay (1694–1774), the marquis de Mirabeau (1715–1789) and Anne-Robert-Jacques Turgot (1727–1781) dominated the movement, which immediately preceded the first modern school, classical economics, which began with the publication of Adam Smith's The Wealth of Nations in 1776.

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...) -
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...) -

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 for 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 might have contributed to war and motivated colonial expansion. Mercantilist theory varies in sophistication from one writer to another and has evolved over time.

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 government and 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.

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.

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...) -
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.

Wilhelm Röpke
Wilhelm Röpke (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...) -

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...) -
Post-Keynesian economics is a school of economic thought with its origins in The General Theory of John Maynard Keynes, with subsequent development influenced to a large degree by Michał Kalecki, Joan Robinson, Nicholas Kaldor, Sidney Weintraub, Paul Davidson, Piero Sraffa and Jan Kregel. Historian Robert Skidelsky argues that the post-Keynesian school has remained closest to the spirit of Keynes' original work. It is a heterodox approach to economics. (Full article...)

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...) -
Microeconomics analyzes the market mechanisms that enable buyers and sellers to establish relative prices among goods and services. Shown is a marketplace in Delhi.
Microeconomics is a branch of economics that studies the behavior of individuals and firms in making decisions regarding the allocation of scarce resources and the interactions among these individuals and firms. Microeconomics focuses on the study of individual markets, sectors, or industries as opposed to the economy as a whole, which is studied in macroeconomics.
One goal of microeconomics is to analyze the market mechanisms that establish relative prices among goods and services and allocate limited resources among alternative uses[citation needed]. Microeconomics shows conditions under which free markets lead to desirable allocations. It also analyzes market failure, where markets fail to produce efficient results. (Full article...) -
Mutualism is an anarchist school of thought and anti-capitalist market socialist economic theory that advocates for workers' control of the means of production, a market economy made up of individual artisans 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.

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...) -

Ernst Friedrich Schumacher CBE (16 August 1911 – 4 September 1977) was a British statistician and economist who is best known for his proposals for human-scale, decentralised and appropriate technologies. He served as Chief Economic Advisor to the British National Coal Board from 1950 to 1970, and founded the Intermediate Technology Development Group (now known as Practical Action) in 1966.
In 1995, his 1973 book Small Is Beautiful: A Study of Economics As If People Mattered was ranked by The Times Literary Supplement as one of the 100 most influential books published since World War II. In 1977 he published A Guide for the Perplexed as a critique of materialistic scientism and as an exploration of the nature and organisation of knowledge. (Full article...) -
Ragnar Anton Kittil Frisch (3 March 1895 – 31 January 1973) was an influential Norwegian economist known for being one of the major contributors to establishing economics as a quantitative and statistically informed science in the early 20th century. He coined the term econometrics in 1926 for utilising statistical methods to describe economic systems, as well as the terms microeconomics and macroeconomics in 1933, for describing individual and aggregate economic systems, respectively. He was the first to develop a statistically informed model of business cycles in 1933. Later work on the model, together with Jan Tinbergen, won the first Nobel Memorial Prize in Economic Sciences in 1969.
Frisch became dr.philos. with a thesis on mathematics and statistics at the University of Oslo in 1926. After his doctoral thesis, he spent five years researching in the United States at the University of Minnesota and Yale University. After teaching briefly at Yale from 1930–31, he was offered a full professorship in economics, which he declined after pressures by colleagues to return to the University of Oslo. After returning to Oslo, Frisch was first appointed by the King-in-Council as Professor of Economics and Statistics at the Faculty of Law, University of Oslo (then the Royal Frederick University) in 1931, before becoming leader of the newly founded Institute of Economics at the University of Oslo in 1932. He remained at the University of Oslo until his retirement in 1965. (Full article...) -
Georgist campaign button from the 1890s in which the cat on the badge refers to a slogan "Do you see the cat?" to draw analogy to the land question
Georgism, also called in modern times Geoism, and known historically as the single tax movement, is an economic ideology holding that people should own the value that they produce themselves, while the economic rent derived from land—including from all natural resources, the commons, and urban locations—should belong equally to all members of society. Developed from the writings of American economist and social reformer Henry George, the Georgist paradigm seeks solutions to social and ecological problems, based on principles of land rights and public finance that attempt to integrate economic efficiency with social justice.
Georgism is concerned with the distribution of economic rent caused by land ownership, natural monopolies, pollution rights, and control of the commons, including title of ownership for natural resources and other contrived privileges (e.g., intellectual property). Any natural resource that is inherently limited in supply can generate economic rent, but the classical and most significant example of land monopoly involves the extraction of common ground rent from valuable urban locations. Georgists argue that taxing economic rent is efficient, fair, and equitable. The main Georgist policy recommendation is a tax assessed on land value, arguing that revenues from a land value tax (LVT) can be used to reduce or eliminate existing taxes (such as on income, trade, or purchases) that are unfair and inefficient. Some Georgists also advocate for the return of surplus public revenue to the people by means of a basic income or citizen's dividend. (Full article...) -
A mixed economy is an economic system that accepts both private businesses and nationalized government services, like public utilities, safety, military, welfare, and education. A mixed economy also promotes some form of regulation to protect the public, the environment, or the interests of the state.
This is in contrast to a laissez faire capitalist economy which seeks to abolish or privatize most government services while wanting to deregulate the economy, and a fully centrally planned economy that seeks to nationalize most services like under the early Soviet Union. Examples of political philosophies that support mixed economies include Keynesianism, social liberalism, state capitalism, fascism, social democracy, the Nordic model, and China's socialist market economy, Vietnam's socialist-oriented market economy.

Decision theory or the theory of rational choice is a branch of probability, economics, and analytic philosophy that uses the tools of 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 for the rational agent models used to mathematically model and analyze individuals in fields such as sociology, economics, criminology, cognitive science, and political science.

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. Unlike other leading theories of the business cycle, 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, and governments should therefore concentrate on long-run structural policy changes and not intervene through discretionary fiscal or monetary policy designed to actively smooth out economic short-term fluctuations.
According to RBC theory, business cycles are therefore "real" in that they do not represent a failure of markets to clear but rather reflect the most efficient possible operation of the economy, given the structure of the economy. (Full article...) -

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...)
