Neo-Keynesian Economics

Neo-Keynesian economics is a school of macroeconomic thought that was developed in the post-war period from the writings of John Maynard Keynes. A group of economists (notably John Hicks, Franco Modigliani, and Paul Samuelson), attempted to interpret and formalize Keynes' writings, and to synthesize it with the neo-classical models of economics. Their work has become known as the neo-classical synthesis, and created the models that formed the core ideas of neo-Keynesian economics. These ideas dominated mainstream economics in the post-war period, and formed the mainstream of macroeconomic thought in the 1950s, 60s and 70s.

In the 1970s a series of developments occurred that shook neo-Keynesian theory. The advent of stagflation, and the work of monetarists like Milton Friedman, cast doubt on neo-Keynesian theories. The result would be a series of new ideas to bring tools to Keynesian analysis that would be capable of explaining the economic events of the 1970s. The next great wave of Keynesian thinking began with the attempt to give Keynesian macroeconomic reasoning a microeconomic basis. The new Keynesians helped create a "new neo-classical synthesis" that currently forms the mainstream of macroeconomic theory. Following the emergence of the new Keynesian school, neo-Keynesians have sometimes been referred to as Old-Keynesians.
