I have worked in different areas of economic theory, including auction theory, game theory, decision theory and market design. Some of those papers have established equilibrium existence in some auctions and games. I also have papers studying economic aspects of equilibria in economies in which consumers have some kind of special preference (not the standard expected utility).
