An abundant literature is concerned with the existence of equilibrium in incomplete markets where participation to … convex subsets of the portfolio space. Our contribution to the literature on general equilibrium of financial markets is …

The order and lattice structure of the equilibrium set in games with strategic complements do not survive a minimal … comparable. In such cases, the equilibrium set is a non-empty, complete lattice, if, and only if, there is a unique equilibrium …. Moreover, in such cases, with linearly ordered strategy spaces, the game has at most one symmetric equilibrium. Several …

We consider global games with general payoff structures and prove existence of equilibrium. This shows that the global … of more general equilibrium behavior, especially as research in global games moves beyond the case of strategic … be used to show existence of equilibrium in global games with both complementarity and congestion. This proves existence …
