Economics is a social science that studies the production, distribution, and consumption of goods and services.
Keynesian economics are the various macroeconomic theories and models of how aggregate demand 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.
Labour economics, or labor economics, seeks to understand the functioning and dynamics of the markets for wage labour. Labour is a commodity that is supplied by labourers, usually in exchange for a wage paid by demanding firms. Because these labourers exist as parts of a social, institutional, or political system, labour economics must also account for social, cultural and political variables.
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 national economy as a whole, which is studied in macroeconomics.
Monopolistic competition is a type of imperfect competition such that there are many producers competing against each other but selling products that are differentiated from one another and hence not perfect substitutes. In monopolistic competition, a company takes the prices charged by its rivals as given and ignores the impact of its own prices on the prices of other companies. If this happens in the presence of a coercive government, monopolistic competition will fall into government-granted monopoly. Unlike perfect competition, the company maintains spare capacity. Models of monopolistic competition are often used to model industries. Textbook examples of industries with market structures similar to monopolistic competition include restaurants, cereals, clothing, shoes, and service industries in large cities. The "founding father" of the theory of monopolistic competition is Edward Hastings Chamberlin, who wrote a pioneering book on the subject, Theory of Monopolistic Competition (1933). Joan Robinson's book The Economics of Imperfect Competition presents a comparable theme of distinguishing perfect from imperfect competition. Further work on monopolistic competition was undertaken by Dixit and Stiglitz who created the Dixit-Stiglitz model which has proved applicable used in the sub fields of international trade theory, macroeconomics and economic geography.
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.
Paul Anthony Samuelson was an American economist who was the first American to win the Nobel Memorial Prize in Economic Sciences. When awarding the prize in 1970, the Swedish Royal Academies stated that he "has done more than any other contemporary economist to raise the level of scientific analysis in economic theory".
Edmund Strother Phelps is an American economist and the recipient of the 2006 Nobel Memorial Prize in Economic Sciences.
Heterodox economics is any economic thought or theory that contrasts with orthodox schools of economic thought, or that may be beyond neoclassical economics. These include institutional, evolutionary, feminist, social, Post-Keynesian, ecological, Austrian, humanistic, complexity, Marxian, socialist, anarchist and modern monetary theory economics.
Mainstream economics is the body of knowledge, theories, and models of economics, as taught by universities worldwide, that are generally accepted by economists as a basis for discussion. Also known as orthodox economics, it can be contrasted to heterodox economics, which encompasses various schools or approaches that are only accepted by a minority of economists.
Applied economics is the application of economic theory and econometrics in specific settings. As one of the two sets of fields of economics, it is typically characterized by the application of the core, i.e. economic theory and econometrics to address practical issues in a range of fields including demographic economics, labour economics, business economics, industrial organization, agricultural economics, development economics, education economics, engineering economics, financial economics, health economics, monetary economics, public economics, and economic history. From the perspective of economic development, the purpose of applied economics is to enhance the quality of business practices and national policy making.
Economics education or economic education is a field within economics that focuses on two main themes:
The pluralism in economics movement is a campaign to change the teaching and research in economics towards more openness in its approaches, topics and standpoints it considers. The goal of the movement is to "reinvigorate the discipline ... [and bring] economics back into the service of society". Some have argued that economics had greater scientific pluralism in the past compared to the monist approach that is prevalent today. Pluralism encourages the inclusion of a wide variety of neoclassical and heterodox economic theories—including classical, Post-Keynesian, institutional, ecological, evolutionary, feminist, Marxist, and Austrian economics, stating that "each tradition of thought adds something unique and valuable to economic scholarship".
The neoclassical synthesis (NCS), neoclassical–Keynesian synthesis, or just neo-Keynesianism — academic movement and paradigm in economics that worked towards reconciling the macroeconomic thought of John Maynard Keynes in his book The General Theory of Employment, Interest and Money (1936) with neoclassical economics.
New classical macroeconomics, sometimes simply called new classical economics, is a school of thought in macroeconomics that builds its analysis entirely on a neoclassical framework. Specifically, it emphasizes the importance of rigorous foundations based on microeconomics, especially rational expectations.
Walter Edward Williams was an American economist, commentator, and academic. Williams was the John M. Olin Distinguished Professor of Economics at George Mason University, a syndicated columnist, and author. Williams held classical liberal and libertarian views, and wrote frequently for Townhall, WND, and Jewish World Review. Williams was also a popular guest host of the Rush Limbaugh radio show when Limbaugh was unavailable.
In economics, a monopsony is a market structure in which a single buyer substantially controls the market as the major purchaser of goods and services offered by many would-be sellers. The microeconomic theory of monopsony assumes a single entity to have market power over all sellers as the only purchaser of a good or service. This is a similar power to that of a monopolist, which can influence the price for its buyers in a monopoly, where multiple buyers have only one seller of a good or service available to purchase from.
Macroeconomic theory has its origins in the study of business cycles and monetary theory. In general, early theorists believed monetary factors could not affect real factors such as real output. John Maynard Keynes attacked some of these "classical" theories and produced a general theory that described the whole economy in terms of aggregates rather than individual, microeconomic parts. Attempting to explain unemployment and recessions, he noticed the tendency for people and businesses to hoard cash and avoid investment during a recession. He argued that this invalidated the assumptions of classical economists who thought that markets always clear, leaving no surplus of goods and no willing labor left idle.
Jacques H. Drèze was a Belgian economist noted for his contributions to economic theory, econometrics, and economic policy as well as for his leadership in the economics profession. Drèze was the first President of the European Economic Association in 1986 and was the President of the Econometric Society in 1970.
Victoria Chick was a Post Keynesian economist known for her essays on monetary theory, banking and methodology. Her writing on Keynes's General Theory made her one of the foremost interpreters of his work. After the 2008 banking crisis she coined a corollary to Gresham's Law, arguing that in orthodox economics "bad theory drives out good."
