We analyze collusion in an infinitely repeated version of a standard auction with a continuum of types. Because of the lack of efficiency results in this setting the literature has focused on determining and comparing benchmarks on how well bidders can collude. Aoyagi (2003) has shown that the...

The experiment disentangles communication and social effect in face-to-face communication. The results question the previous interpretation of communication effects in ultimatum bargaining, and suggest that separate processes, both of a strategic and of an affective-social nature induce...

This paper proves the existence of non-empty cores for directed network problems with quotas and for those combinatorial allocation problems which permit only exclusive allocations.

This article considers a model of spatial competition where firms and consumers are located in a semicircular space rather than in the whole circle (Salop's model) or the linear city (Hotelling's model), under the assumptions of both, convex and concave, transportation costs. The paper tries to...

We consider one-to-one markets where workers can apply to a centralized procedure either alone or as a couple, in order to reach a core- stable matching of firms and workers. We impose stringent restrictions on the preferences of couples capturing the fact that spouses want to live in the same...

By a result of Pearce (1984), in a finite strategic form game, the set of a player's serially undominated strategies coincides with her set of rationalizable strategies. In this note we consider an extension of this result that applies to games with continuous utility functions that are...

This paper presents a sufficient condition for the quasi-acyclic condition. A game is quasi-acyclic if from any strategy profile, there exists a finite sequence of strict best replies that ends in a pure strategy Nash equilibrium. The best-reply dynamics must converge to a pure strategy Nash...

This note provides a generalization of the equal allocation of nonseparable costs (EANSC) on multi-choice games. Also, we extend to the multi-choice games case the complement reduced game and characterize the extended EANSC by means of related property of consistency.

The spatial voting approach is extended to account for the existence of a loyalty effect driving the choice of parties' platforms during elections. There emerges a non-linear relationship between these variable, whereby a party sticking to its historical heritage may lose to a rival more keen to...

In a game where firms select locations, technological interactions through the exchange of intermediate goods bring about a multiplicity of locational equilibria and entail a pattern of agglomeration of the productive activity with the variation of transport costs that is opposite to the one...
