The index theorem for a GEI economy when the degree of incompleteness is even
The purpose of this paper is to present a method to compute the index in an incomplete market economy. We show that generically in endowments and the asset structure the index theorem holds when the deficiency of markets, S-J, is even. The result is based on the indices of homotopies which have been presented for computation of an equilibrium in incomplete market economies.
