STEIN* Keynesians, monetarists, and new classi-cal economists agree that the steady-state rate of inflation is closely related to the growth of the money supply, and that mone-tary policy cannot affect the equilibrium rate of unemployment. There are a number of important differences between classical and Keynesian economics, but in general classic theory teaches that things in the marketplace like economic growth and investment capital are most effectively driven by consumers and free choice, while the Keynesian school of thought spends more time considering government regulation and oversight. The new classical macroeconomics is a school of economic thought that originated in the early 1970s in the work of economists centered at the Universities of Chicago and Minnesotaparticularly, Robert Lucas (recipient of the Nobel Prize in 1995), Thomas Sargent, Neil Wallace, and Edward Prescott (corecipient of the Nobel Prize in 2004).

The new classical macroeconomics offers a strong criticism of orthodox Keynesian macro­economics on the ground that Keynesian macroeconomic models are primarily ad hoc in the sense that they are not based on economic agents’ optimisation programme. The main book collecting and organizing the first decade of New Keynesian work was the Mankiw and Romer volume, New Keynesian Economics, published in 1990. The Keynesian theory was developed as a response to the Great Depression. The new synthesis provides the theoretical foundation for much of contemporary mainstream economics. endobj But in new Keynesian analysis, households and firms do not coordinate their choices without costs.

Like the New Classical approach, New Keynesian macroeconomic analysis usually assumes that households and firms have rational expectations.

In today’s context, they can be broadly classified in two categories: Post Keynesian (PK) and New Keynesian (NK). Macrotheory could be adapted to microtheory; and the converse. They said that taxpayers would anticipate the debt caused by deficit spending. The main reason for the development of the Keynesian theory is John Maynard Keynes question about the classical system.
