Lars P. Syll — Macroeconomic challenges


It would be better to just face the truth — it is impossible to describe interaction and cooperation when there is essentially only one actor.
Macroeconomic challenges

The assumption of representative agents is atomistic in the sense that atoms are indistinguishable elements of a homogenous system that is characterized by timeless invariant relationships that can be captured as mathematical functions — as it physics. However, social systems are not at all like physical systems, are they? 

So why assume atomism in the first place, when it is bound to fail. The only realistic answer I have seen is methodological convenience. Such models are tractable. Modeling complexity is hard.
