Perfect information games have a particularly simple structure of equilibria in the associated normal form. For generic such games each of the finitely many connected components of Nash equilibria is contractible. For every perfect information game there is a unique connected and contractible...

Equilibrium paths in economies of overlapping generations depend on the frequency of trade. In a standard example, determinacy obtains as the frequency of trades tends to infinity or trade occurs in continuous time. If time extends infinitely into the infinite past as well as into the infinite...

This paper establishes existence of subgame perfect equilibrium for a general class of sequential multi-lateral bargaining games. The only required hypothesis is that utility functions are continuous on the space of economic outcomes. In particular, no assumption on the space of feasible payoffs...
