THE IDENTIFICATION OF PREFERENCES FROM MARKET DATA UNDER UNCERTAINTY

摘要: We show that even under incomplete markets, the equilibrium manifold identifies aggregate demand and individual demands everywhere in their domains. Moreover, partial observation of manifold, we construct maximal domains identification. For this, assume conditions smoothness, interiority regularity, but avoid implausible observational requirements. It is crucial there be date-zero consumption. As a by-product, develop some duality theory markets.
