This paper explores, theoretically and experimentally, a fixed-price mechanism bywhich, if aggregate demand exceeds supply, bidders are proportionally rationed. Ifdemand is uncertain, equilibrium consists in overstating true demand to alleviate theeffects of being rationed. Overstating is more...

We introduce a procedure that uses basic topological characteristics of equilibrium correspondences of standard equilibrium concepts, to define broad equivalence classes of finite generic games in normal form. The proposed procedure is viewed as a potentially useful way of both organizing the...

We consider a continuous-time variant of the classical Economic Lot-Sizing (ELS) problem. In this model, the setup cost is a continuous function with lower bound $K_min 0$, the demand and holding costs are integrable functions of time and the replenishment decisions are not restricted to be...

This paper introduces two set valued Nash equilibrium refinements that are a natural generalization of the concept of stable set of equilibria introduced in Kohlberg and Mertens (1986) and satisfy all the properties defined in Mertens (1989). It also establishes a connection between Nash...

This paper introduces games with a saddle function. A saddle function is a real valued function on the set of action profiles such that, for one player, minimizing the function implies choosing her best-response, and, for the other players, maximizing it implies choosing their best-responses. We...

In this paper we extend the basic model of Cournot competition to the case where both the demand function and the cost functions of each firm depend on the amounts produced by competitors. In this modified setting, proving existence of equilibria becomes harder. We develop a generalization of...

The objective of the paper is to analyze the formation of social networks where individuals are allowed to engage in several groups at the same time. These group structures are interpreted here as social networks. Each group is supposed to have specific rules or constitutions governing which...

I develop a model of stochastic costly signaling in the presence of exogenous imperfect information, and study whether equilibrium signaling decreases ('information substitutes') or increases ('information complements') if the accuracy of exogenous information increases. A stochastic pure costly...

This paper reexamines the work of Kempf and Rota-Graziosi (J. Pub. Econ. 94: 768-776, 2010), which shows that leadership by the small region is the risk dominant equilibrium under the endogenous timing game. They obtain this result in a model where the asymmetry among countries translates into...

Multinational companies can shift profit and income between branches in order to reduce the overall tax liabilities of the company. The result is a tax competition between countries. In this paper we consider the sequential choice of tax rates to illustrate the potential effects of tax...
