The Number of Equilibria of Smooth Infinite Economies

  • Enrique Covarrubias

We construct an index theorem for smooth infinite economies that shows that generically the number of equilibria is odd. As a corollary, this gives a new proof of existence and gives conditions that guarantee global uniqueness of equilibria.
