Riley (1979)'s reactive equilibrium concept addresses problems of equilibrium existence in competitive markets with … adverse selection. The game-theoretic interpretation of the reactive equilibrium concept in Engers and Fernandez (1987) yields … the Rothschild-Stiglitz (1976)/Riley (1979) allocation as an equilibrium allocation, however multiplicity of equilibrium …

prove existence of a Stationary Markov Nash Equilibrium via constructive methods. In addition, we provide monotone …

We consider a class of equilibrium refinements for finite games in strategic form. The refinements in this family are … indexed from least to most restrictive. Proper equilibrium is obtained as a special case within the class; all other concepts … are stronger than trembling-hand perfection and weaker than proper equilibrium, so they provide a collection of …

I look at the equilibrium effects of homophily in network formation games having positive externalities. I show that … homophily at equilibrium. I present an empirical procedure that allows an evaluation of the role of network effects on the …

We introduce extended proper equilibrium, which refines proper equilibrium (Myerson, 1978) by adding across …-player restrictions on trembles. This refinement coincides with proper equilibrium in games with two players but adds new restrictions in … equilibrium is regarded by all as more likely than any costly tremble, even one by a different player. At least one extended …

equilibria, as long as $A^N\geq K$, I show that equilibrium selection probabilities are also identified, a result that is useful …

-confirming equilibrium describes the behavioral consequences of this intuition in a noncooperative game. We augment a game with a network to …' strategies. In peer-confirming equilibrium, there is common belief that players (i) behave rationally and (ii) correctly …
