Keynesian Theory of Income and Employment: Definition and Explanation: John Maynard Keynes was the main critic of the classical macro economics. In line with Hayek theory of unemployment, Trehan (2001) provides an important explanation of the search theory of unemployment. Few would gainsay that Keynes “opened up new vistas and new pathways to a whole generation of economists,” but many would now consider his analysis less than adequate for meeting such special problems as cyclical forecasts and controls, persistent inflation, the maintenance of full employment, booms, secular growth, non-linear structural relations and macro-functional distribution. (f) Lastly, the Keynesian economics fails to provide solutions to a number of socio-economic problems facing the developed countries. Prof. Ackley calls the Keynesian model as “too static.”. But the Keynesian revolution lies in its macro-dynamic orientation of aggregate income, employment, output, consumption, demand, supply, saving and investment. The problem of technological unemployment had been ignored by Keynes because he failed to visualise the rapid technological discoveries which took place in the advanced capitalist countries. He was a benefactor of humanity. But as pointed out by Professor Harris, “It is a matter of judgement whether the General Theory is simply classical economics further developed or embroidered, or whether Keynesian economics represents a genuine break.”. theory suggested that high unemployment rates would lead to lower wage rates, which would lead to lower prices, which would lead to higher demand because of the increased purchasing power of existing wealth. The Keynesian theory of interest rate determination has been severely criticised by post-Keynesian economists, keynes made the rate of interest determined by the demand for and supply of money. in  Social sciences A Dictionary of Economics », Subjects: By integrating the value theory and monetary theory through the theory of output, Keynes made money non-neutral as opposed to the classical view of neutrality of money. The critical evaluation of Keynesian economics reveals that there are the Keynesians who eulogise Keynes and there are the anti-Keynesians like Hazlitt who “could not find a single doctrine that was both true and original.”, On the other hand, Keynes’ greatest follower Dillard writes, “Keynes was an original thinker in the sense that he arrived at his ideas in his own way. It is a lagless analysis. Keynes the master Keynesian economics gets its name, theories, and prin-ciples from British economist John Maynard Keynes (1883–1946), who is regarded as the founder of modern macroeconomics.

Keynesian unemployment can be reduced by the use of monetary or fiscal policy to increase effective demand. Keynes, therefore, favoured a flexible monetary policy to a flexible wage policy to raise the level of employment in the economy. As rightly pointed out by Prof. Hansen, “The General Theory has helped to make us think of economics in dynamic rather than in static terms.”, Keynes’ most significant contribution lies in saving capitalism from the catastrophe it had fallen in the 1930’s. The Classical Theory of Unemployment Figure 1: A Supply and Demand Model for Labor. The demand for money arises from the transactions motive, the precautionary motive and the speculative motive. Keynes propounded the opposite view that demand creates its own supply. Keynesian Economics is an economic theory of total spending in the economy and its effects on output and inflation developed by John Maynard Keynes.
