This paper studies models where the optimal response functions under consideration are non-increasing in endogenous variables, and weakly increasing in exogenous parameters. Such models include games with strategic substitutes, and include cases where additionally, some variables may be...

This paper provides a theoretical and empirical investigation of the effects of HIV/AIDS on communitylevel informal financial institutions such as rotating savings and credit associations. Our theoretical model illustrates that the mortality risk implied by the HIV/AIDS pandemic can put a...

We apply a fallback model of coalition formation to decisions of the U.S. Supreme Court, focusing on the seven natural courts, which had the same members for at least two terms, between 1969 and 2009. The predictions of majority coalitions on each of the courts are generally bourn out by the 5-4...

In the case of the latter, it produces either one or two stable matches whereby no man and woman would prefer to be matched with each other rather than with...

The Median Voter Theorem is an extremely popular result in Political Economy that holds only if the policy space is unidimensional. This assumption restricts its use to a class of very simple problems. In most applications in the literature this implied an oversimplification of the problem...
