On a Theorem of Arrow

The Review of Economic Studies, 1975
In a famous article [1], Arrow studied the allocation of risk-bearing in a competitive economy consisting of I individuals, C commodities and S states. Two schemes were considered. The first scheme was one equipped with S x C complete contingent commodity claims. These claims were assumed to be tradable in the market.
