One of Keynes's pupils at Cambridge was Joan Robinson (1903–1983), a member of Keynes's Cambridge Circus, who contributed to the notion that competition is seldom perfect in a market, an indictment of the theory of markets setting prices. In The Production Function and the Theory of Capital (1953) Robinson tackled what she saw to be some of the circularity in orthodox economics. Neoclassicists assert that a competitive market forces producers to minimize the costs of production. Robinson said that costs of production are merely the prices of inputs, like capital. Capital goods get their value from the final products.  And if the price of the final products determines the price of capital, then it is, argued Robinson, utterly circular to say that the price of capital determines the price of the final products. Goods cannot be priced until the costs of inputs are determined. This would not matter if everything in the economy happened instantaneously, but in the real world, price setting takes time – goods are priced before they are sold. Since capital cannot be adequately valued in independently measurable units, how can one show that capital earns a return equal to the contribution to production?
Alfred Eichner (1937–1988) was an American post-Keynesian economist who challenged the neoclassical price mechanism and asserted that prices are not set through supply and demand but rather through mark-up pricing.
Eichner is one of the founders of the post-Keynesian school of economics and was a professor at Rutgers University at the time of his death. Eichner's writings and advocacy of thought, differed with the theories of John Maynard Keynes, who was an advocate of government intervention in the free market and proponent of public spending to increase employment. Eichner argued that investment was the key to economic expansion. He was considered an advocate of the concept that government incomes policy should prevent inflationary wage and price settlements in connection to the customary fiscal and monetary means of regulating the economy.
Richard Kahn (1905–1989) was a member of the Cambridge Circus who in 1931 proposed the Multiplier.

Piero Sraffa (1898–1983) came to England from Fascist Italy in the 1920s, and became a member of the Cambridge Circus.  In 1960 he published a small book called Production of Commodities by Means of Commodities, which explained how technological relationships are the basis for production of goods and services. Prices result from wage-profit tradeoffs, collective bargaining, labour and management conflict and the intervention of government planning. Like Robinson, Sraffa was showing how the major force for price setting in the economy was not necessarily market adjustments.
John Hicks (1904–1989) of England was a Keynesian who in 1937 proposed the Investment Saving – Liquidity Preference Money Supply Model, which treats the intersection of the IS and LM curves as the general equilibrium in both markets.

=== New Keynesian macroeconomics ===

In 1977 Edmund Phelps (1933–) (who was awarded the 2006 Nobel Economics Prize) and John B. Taylor (1946–) published a paper proving that staggered setting of wages and prices gives monetary policy a role in stabilizing economic fluctuations if the wages/prices are sticky, even when all workers and firms have rational expectations, which caused Keynesian economics to make a comeback among mainstream economists with New Keynesian Macroeconomics. Its central theme is the provision of a microeconomic foundation for Keynesian macroeconomics, obtained by identifying minimal deviations from the standard microeconomic assumptions which yield Keynesian macroeconomic conclusions, such as the possibility of significant welfare benefits from macroeconomic stabilization.
In 1985 George Akerlof (1940–) and Janet Yellen (1946–) published menu costs arguments showing that, under imperfect competition, small deviations from rationality generate significant (in welfare terms) price stickiness.
In 1997 American economist Michael Woodford (1955–) and Argentine economist Julio Rotemberg (1953–) published the first paper describing a microfounded DSGE New Keynesian macroeconomic model.

=== Sidney Weintraub, Paul Davidson and Post-Keynesian economics ===
In 1975 American economists Sidney Weintraub (1914–1983) and Henry Wallich (1914–1988) published A Tax-Based Incomes Policy, promoting Tax-Based Incomes Policy (TIP), using the income tax mechanism to implement an anti-inflationary incomes policy. In 1978 Weintraub and American economist Paul Davidson (1930–) founded the Journal of Post Keynesian Economics. This opened the door to many younger economists such as E. Ray Canterbery (1935–). Always Post Keynesian in his style and approach, Canterbery went on to make contributions outside traditional Post Keynesianism. His friend, John Kenneth Galbraith, was a long-time influence.

=== The credit theory of money ===

In 1913 English economist-diplomat Alfred Mitchell-Innes (1864–1950) published What is Money?, which was reviewed favorably by John Maynard Keynes, followed in 1914 by The Credit Theory of Money, advocating the Credit Theory of Money,
which economist L. Randall Wray called "The best pair of articles on the nature of money written in the twentieth century."
