Does Macroeconomics Need Microeconomic Foundations?
(Published in Special Issue Reconstructing Macroeconomics)


I argue that it is microeconomics that needs foundations, not macroeconomics. Preferences need to be built on biology, and, in particular, on neuroscience. In contrast, macroeconomics could benefit from rationalizations of aggregate economic phenomena by non-equilibrium statistical physics.

I reckon that before discussing this subject the author should define and explain what he means by macroeconomics. Micro is easy enough to explain, since it requires the relationship and behavour of two independent entities only, such as a laborer and an employer. However the macroeconomic "big picture" must include ...[more]

... the whole of our social system and this comprises of a lot mopre than the two entities suggested above.

Macroeconomics is the result of the growth or development of a number of individual microeconomic relationships within a system which seeks a state of equilibrium when it is all cahnging at the same time. This ststement comes from logic not from reading the paper. So it seems to me that once the problem and subject are properly defined and understood, the conclusion is immediately found.
