Macroeconomics/MacroeconomicsVsMonetarism/MacroeconomicsVsKeynesianism/Muth/Lucas: Problems of monetarism or Keynesianism are the lack of explanation of wage and price rigidities or wage and price formation at all, or the arbitrary approach in modeling the expectations of economic entities. Ultimately, there was a lack of a microeconomic foundation for macroeconomics. The new Classical Macroeconomics, of which John F. Muth (1930-2005) and Robert E. Lucas (born 1937) are the main representatives tried to close this gap.
Two assumptions are fundamental to this approach: On the one hand, it is assumed that expectations are rational, i.e. that the modelled economic entities utilize all information inherent in the model and therefore arrive at the same forecasts as the model itself. On the other hand, price flexibility and the permanent equilibrium of the markets are assumed. Accordingly, fluctuations in production and employment are not interpreted as imbalances but as a sequence of equilibrium positions.
New Classical Macroeconomics Thesis: There is no involuntary unemployment!
VsMuth/VsLucas/VsMacroeconomics: the macroeconomic problems observed were more or less defined away. There was no real foundation through a microeconomic approach.
