Since the criticism of Keynesian economics by new-Classical economists, it has become fashionable to explain and justify theoretical arguments in macroeconomics by microeconomic reasoning. It seems to me, however, that microeconomic foundations based on the standard competitive theory do not agree with our common sense perception. So, it may not be fair to criticize Keynesian economics because of its lack of micro foundations. This paper studies the macroeconomic implications of imperfect competition. In particular, I pursue two implications of imperfect competition as the micro foundations of macroeconomics. One is that under imperfect competition firms have quantity expectations instead of price expectations when they make decisions. The other is that the existence of imperfect competition allows us to model an economy with some degree of increasing returns to scale. I have shown that these two aspects of imperfect competition provide more realistic microeconomic reasoning and lead to more fruitful macroeconomic analysis.
