In this paper, we analyze a generalization of the evolutionary model of Kandori, Mailath, & Rob (1993) where the population is partitioned into groups and evolution takes place "in parallel" at the following two levels: (i) within groups, at the lower level; among groups, at the higher one....

In Hawk-Dove games with mulitiplicity of equilibria, we study which equilibria are selected using various equilibrium selection methods. Using a uniform price auction as an illustrative example, we apply the tracing procedure method of Harsanyi and Selten (1988), the robustness to strategic...

This paper demonstrates that there is a discrepancy between the ideas expressed in Lindahl (1919) and the current-day definition of Lindahl equilibrium. It describes how the ideas expressed by Lindahl (1919) developed into the equilibrium concept for public good economies that now carries...

This note shows that the loss deviations in Selten's (1995) risk dominance measure are the same as the arguments of the probability of a strategy that supports a sequential equilibrium. Risk dominance is used to select among Nash equilibria, while sequential equilibrium, which is stronger than...

This paper provides a unified approach to equilibrium analysis in models for competing mechanisms (e.g., Szentes (2009), Yamashita (2010)), which may differ in terms of delegation of action choice, announcement of mechanisms, observability of messages, and equilibrium notions

In this paper, we study full implementation problem by mechanisms that allow delay. The delay on the equilibrium path may be zero, infinitesimally small or a fixed positive number. In all these three cases, implementable rules are characterized by a monotonicity-like condition alone, including...

Diermeier and Fong (2008a) recently proposed a legislative bargaining model with reconsideration in the context of a distributive policy environment. In this paper we prove general existence and necessary conditions for pure-strategy stationary equilibria for any finite policy space and...

We come close to characterizing the class of social choice correspondences that are implementable in rationalizable strategies. We identify a new condition, which we call set-monotonicity, and show that it is necessary and almost sufficient for rationalizable implementation. Set-monotonicity is...

We consider the implementation problem under incomplete information and private values. We investigate double implementability of social choice functions in dominant strategy equilibria and ex post equilibria. We show that the notion of an ex post equilibrium is weaker than the notion of a...
