Heterodox economics in the context of "Marxian economics"

Institutional economics focuses on understanding the role of the evolutionary process and the role of institutions in shaping economic behavior. Its original focus lay in Thorstein Veblen's instinct-oriented dichotomy between technology on the one side and the "ceremonial" sphere of society on the other. Its name and core elements trace back to a 1919 American Economic Review article by Walton H. Hamilton. Institutional economics emphasizes a broader study of institutions and views markets as a result of the complex interaction of these various institutions (e.g. individuals, firms, states, social norms). In general, the distinction of Institutional Economics is that, while Classical Economics focused on exchange between actors in markets or through macro level income flows and factors of production, Institution Economists placed their focused within productive units as organizations composed of people in societies. This gave Institutional Economics a broad purview within the social sciences, and an empirical focus on real world interactions to explain things abstract models based on homo economicus did not. The earlier tradition continues today as a leading heterodox approach to economics. Institutional Economics, particularly New Institutional Economics, also continues to contribute to a wide variety of disciplines, including Industrial Relations, Organizational Theory, Management Studies and Public Administration, among others.

"Traditional" institutionalism rejects the reduction of institutions to simply tastes, technology, and nature (see naturalistic fallacy). Tastes, along with expectations of the future, habits, and motivations, not only determine the nature of institutions but are limited and shaped by them. If people live and work in institutions on a regular basis, it shapes their world views. Fundamentally, this traditional institutionalism (and its modern counterpart institutionalist political economy) emphasizes the legal foundations of an economy (see John R. Commons) and the evolutionary, habituated, and volitional processes by which institutions are erected and then changed (see John Dewey, Thorstein Veblen, and Daniel Bromley). Institutional economics focuses on learning, bounded rationality, and evolution (rather than assuming stable preferences, rationality and equilibrium). It was a central part of American economics in the first part of the 20th century, including such famous but diverse economists as Thorstein Veblen, Wesley Mitchell, and John R. Commons. Some institutionalists see Karl Marx as belonging to the institutionalist tradition, because he described capitalism as a historically bounded social system; other institutionalist economists disagree with Marx's definition of capitalism, instead seeing defining features such as markets, money and the private ownership of production as indeed evolving over time, but as a result of the purposive actions of individuals.

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.

The economics profession has traditionally been associated with neoclassical economics. However, this association has been challenged by prominent historians of economic thought including David Colander. They argue the current economic mainstream theories, such as game theory, behavioral economics, industrial organization, information economics, and the like, share very little common ground with the initial axioms of neoclassical economics.

Sir Hans Wolfgang Singer (29 November 1910 – 26 February 2006) was a German-born British development economist best known for the Prebisch-Singer thesis, which states that the terms of trade move against producers of primary products. He is one of the primary figures of heterodox economics.

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 1871 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.

Epistemology of finance is a broad field of study that aims at providing a conceptual framework(s) for the interpretation of mathematical models in finance as well as the study of their possible limitations, in order to determine the epistemological standards according to which financial theory should be assessed against any associated empirical reality. A key problem is to what extent the combination of self-reference and adaption (reflexivity) undermine the stability, uniqueness, and usefulness of predictive models in finance and economics.

Within applied financial disciplines (which subsume financial economics, quantitative, and statistical finance) a single common assumption is pervasive; namely, that capital markets, being social systems, adhere sufficiently to epistemic norms. It has been argued that the use of incorrect epistemological assumptions is pervasive in financial economics and economics. These assumed epistemic norms carry with them a priori the necessity of unique, well-defined causal chains that can be meaningfully extracted from data. Both heterodox and mainstream economics retain the view that causality remains relevant as a formalism and that models remain sufficiently stable and unique (including under self-reference) and for this reason typically characterize empirical finance as science.

Stephanie A Kelton (née Bell; born October 10, 1969) is an American heterodox economist and academic, and a leading proponent of modern monetary theory. She served as an advisor to Bernie Sanders's 2016 presidential campaign and worked for the Senate Budget Committee under his chairmanship. She is also the author of The Deficit Myth, a New York Times bestseller, on the subject of modern monetary theory.

Kelton is a professor at Stony Brook University and a senior fellow at the Schwartz Center for Economic Policy Analysis at the New School for Social Research. She was formerly a professor at the University of Missouri–Kansas City.
