Keynesian economics
Neoclassical economics dominated microeconomics and, together with Keynesian economics, formed the neoclassical synthesis which dominated mainstream economics as Neo-Keynesian economics from the 1950s to the 1970s. It competed with New Keynesian economics as new classical macroeconomics in explaining macroeconomic phenomena from the 1970s till the 1990s, when it was identified as having become a part of the new neoclassical synthesis along with New Keynesianism. There have been many critiques of neoclassical economics, a number of which have been incorporated into newer versions of neoclassical theory, whilst some remain distinct fields.
