An index formula for production economies with externalities

Journal of Mathematical Economics, 2008, vol. 44, issue 12, 1385-1397

Abstract: We prove that the degree of the equilibrium correspondence of an economy with increasing returns and external effects is equal to (-1)L-1 where L is the dimension of the space of goods. This allows us to infer existence, finiteness and uniqueness results.
