Keynesian Economics

Paper Summary:

This paper explains, in contrast to the classical view that demand should be held relatively stable or static, Keynes believed that government spending was necessary to inflate production and infuse the economy with necessary dollars; the Neo-Keynesians applied neoclassical economic theories of monetary policy and the micro economy to Keynesian economics regarding the macro economy. The author defines the 'price output puzzle' as "why do not suppliers reduce prices rather than reduce supply?" This paper concludes that the major three functions of both the Keynesian and Neo-Keynesian theories, which include the consumption function, the investment function, and the liquidity preference function, should all be considered simultaneously, viewing the economy in a holistic fashion.

From the Paper:

"Specifically, the first Neoclassical-Keynesian Synthesis is another way of referring to the Neo-Keynesian Revolution of the so-called IS-LM Model. The IS-LM model represents John Maynard Keynes's General Theory in the form of a system of simultaneous equations "The IS-LM model has remained one of the most formidable pieces of pedagogic machinery and, as far as back-of-the-envelope diagrammatic reasoning is concerned, one of the most efficient ever devised in economics. It is not, however, without substantial problems, both as an internally consistent model or as a representation of Keynes's theory." In other words, this Neo-Keynesian school works wonderfully in theory, but not so well in fact."
