Keynesianism

This school of economic thought, which focuses on macroeconomics, is mainly based on interpretations of John Maynard Keynes’ most important book, the “General Theory of Employment, Interest and Money”, 1936.

Keynes’ main thesis was that unemployment during the Great Depressionwas the result of a decreasing demand, and that the solution was to revive the economic system through public investment. A Keynesian policy would be one that promotes, for example, public works such as building dams or highways.

Supporters of Keynesianism, or Keynesian economics, believe that although businesses and private sector entities working on a liberal environment function in an efficient way, sometimes market failures may appear. For this, they support a certain degree of implication by the public sector in order to prevent these failures and restore the economy if they appear, through fiscal and monetary policies. However, they will give more credit to the former, the latter being more supported by Monetarists.

Keynesianism was the main economic doctrine from 1936 until the advent of Monetarism, with which it coexisted until the stagflation of the seventies.

Joan Robinson, Nicholas Kaldor and John R. Hicks, are just some of the great disciples of Keynes, and therefore Keynesian economists, mainly from the Cambridge School in its not neoclassical meaning, to name a few.
