Generic Existence of Sunspot Equilibria: The Real Asset Case

This paper established the generic existence of sunspot equilibria in a standard two period exchange economy with real assets. We show that for a generic choice of utility functions and endowments, there exists an open set of real asset structures whose payoffs are independent of sunspots such that the economy with this asset structure has a regular sunspot equilibrium. This results also clarifies the relationship between equilibrium multiplicity and existence of sunspot equilibria. Our technique is very general and can be applied to other frameworks as the overlapping generations model with sunspots.
