Mainstream economicsMainstream 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. The economics profession has traditionally been associated with neoclassical economics. This association has however been challenged by prominent historians of economic thought like David Collander.
Transaction costIn economics and related disciplines, a transaction cost is a cost in making any economic trade when participating in a market. The idea that transactions form the basis of economic thinking was introduced by the institutional economist John R. Commons in 1931, and Oliver E. Williamson's Transaction Cost Economics article, published in 2008, popularized the concept of transaction costs. Douglass C. North argues that institutions, understood as the set of rules in a society, are key in the determination of transaction costs.
Heterodox economicsHeterodox 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 (not to be confused with New Keynesian), ecological, Austrian, complexity, Marxian, socialist, and anarchist economics. Economics may be called orthodox or conventional economics by its critics.
New institutional economicsNew Institutional Economics (NIE) is an economic perspective that attempts to extend economics by focusing on the institutions (that is to say the social and legal norms and rules) that underlie economic activity and with analysis beyond earlier institutional economics and neoclassical economics. Unlike neoclassical economics, it also considers the role of culture and classical political economy in economic development.
Economic anthropologyEconomic anthropology is a field that attempts to explain human economic behavior in its widest historic, geographic and cultural scope. It is an amalgamation of economics and anthropology. It is practiced by anthropologists and has a complex relationship with the discipline of economics, of which it is highly critical. Its origins as a sub-field of anthropology began with work by the Polish founder of anthropology Bronislaw Malinowski and the French Marcel Mauss on the nature of reciprocity as an alternative to market exchange.
Historical institutionalismHistorical institutionalism (HI) is a new institutionalist social science approach that emphasizes how timing, sequences and path dependence affect institutions, and shape social, political, economic behavior and change. Unlike functionalist theories and some rational choice approaches, historical institutionalism tends to emphasize that many outcomes are possible, small events and flukes can have large consequences, actions are hard to reverse once they take place, and that outcomes may be inefficient.
EconomyAn economy is an area of the production, distribution and trade, as well as consumption of goods and services. In general, it is defined as a social domain that emphasize the practices, discourses, and material expressions associated with the production, use, and management of scarce resources. A given economy is a set of processes that involves its culture, values, education, technological evolution, history, social organization, political structure, legal systems, and natural resources as main factors.
History of economic thoughtThe history of economic thought is the study of the philosophies of the different thinkers and theories in the subjects that later became political economy and economics, from the ancient world to the present day in the 21st century. This field encompasses many disparate schools of economic thought. Ancient Greek writers such as the philosopher Aristotle examined ideas about the art of wealth acquisition, and questioned whether property is best left in private or public hands.
Economic efficiencyIn microeconomics, economic efficiency, depending on the context, is usually one of the following two related concepts: Allocative or Pareto efficiency: any changes made to assist one person would harm another. Productive efficiency: no additional output of one good can be obtained without decreasing the output of another good, and production proceeds at the lowest possible average total cost. These definitions are not equivalent: a market or other economic system may be allocatively but not productively efficient, or productively but not allocatively efficient.
Constitutional economicsConstitutional economics is a research program in economics and constitutionalism that has been described as explaining the choice "of alternative sets of legal-institutional-constitutional rules that constrain the choices and activities of economic and political agents". This extends beyond the definition of "the economic analysis of constitutional law" and is distinct from explaining the choices of economic and political agents within those rules, a subject of orthodox economics.
