摘要:
The usual assumptions about preferences and production technologies are easily justified when they involve elementary goods (differentiated by dates, locations, and states of nature). But it is far less easy to come up with direct justifications when only composite goods are traded. We show that the equilibria defined by the equality of supply and demand of composite goods coincide with the Walrasian equilibria of suitably defined economies whose commodity space is the composite commodity space. This shows in particular that the relevance of the general equilibrium model is essentially independent of the level of commodity aggregation. (C) 1999 Academic Press.
