Strict rational expectations equilibria with diffuseness
Abstract For smooth static pure-exchange economies under uncertainty, it is shown that a diffuseness condition on the distribution of traders' characteristics as the state of the world varies permits one to use only a weak dimensionality restriction in the proof of the genericity of existence of strict rational expectations equilibria. A generic result on the amount of information conveyed by equilibrium price functions and comparisons with some examples of nonexistence are given.
