The defects of traditional Keynesianism and the achievements and mistakes of neoclassicism inspire some scholars to construct microcosmic-based macroeconomics and find another way to make empirical analysis of labor market and product market.Based on the wage price rigidity and market clearing hypothesis, they take the neoclassical wage price activity flexibility and market clearing hypothesis and combine it with the re-Keynesian conclusion in the macro output and employment decision theory. in this way, new-Keynesianism came into being.
The correct interpretation of the preceding paragraph is that wage, price flexibility and market clearing hypothesis may be the achievements and mistakes of neoclassicism.
