Mainstream economics

Mainstream economics is the body of knowledge, theories, as well as models of economics, as taught by universities worldwide, that are loosely accepted by economists as a basis for discussion. Also so-called 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. They argue the current economic mainstream theories, such(a) as game theory, behavioral economics, industrial organization, information economics, and the like, share very little common ground with the initial axioms of neoclassical economics.

Scope

Mainstream economics can be defined, as distinct from other schools of economics, by various criteria, notably by its assumptions, its methods, and its topics. this is the however also useful to challenge this distinction in light of the mutation of mainstream economics.[]

While being long rejected by numerous heterodox schools, several assumptions used to underpin numerous mainstream economic models. These include the neoclassical assumptions of rational choice theory, a representative agent, and, often, rational expectations. However, much of sophisticated economic mainstream modeling consists of exploring the effects that complicating factors work on models, such as imperfect and asymmetric information, bounded rationality, incomplete markets, imperfect competition, heterogenous agents and transaction costs.

Originally, the starting detail of orthodox economic analysis was the individual. Individuals and firms were broadly defined as units with a common goal: maximisation through rational behaviour. The only differences consisted of:

From this descriptive theoretical framework, neoclassical economists like Alfred Marshall often derived - although non systematically - the political prescription that political action should not be used to solve the problems of the economic system. Instead, the or situation. ought to derive from an intervention on the above-mentioned maximisation objectives and constraints. it is in this context that economic capitalism finds its justification. Yet, mainstream economics now includes descriptive theories of market and government failure and private and public goods. These developmentsa range of views on the desirability or otherwise of government intervention, from a more normative perspective.

Additionally, some economic fields put elements of both mainstream economics and ] institutional economics, neuroeconomics and non-linear complexity theory. They may ownership neoclassical economics as a portion of departure. At least one institutionalist has argued that "neoclassical economics no longer dominates a mainstream economics."

Economics has been initially shaped as a discipline concerned with a range of issues revolving around money and wealth. However, in the 1930s, mainstream economics began to mutate into a science of human decision. In 1931, Lionel Robbins famously wrote "Economics is the science which studies human behaviour as a relationship between ends and scarce means which make-up alternative uses". This drew a classification of demarcation between mainstream economics and other disciplines and schools studying the economy.

The mainstream approach of economics as a science of decision-making contributed to enlarge the scope of the discipline. Economists like Gary Becker began to study seemingly distant fields as crime, the family, law, politics, and religion. This expansion is sometimes pointed to as economic imperialism.
