This paper studies the identification of best response functions in binary games without making strong parametric assumptions about the payoffs. The best response function gives the utility maximizing response to a decision of the other players. This is analogous to the response function in the...

Se estudia el oligopolio de Cournot donde el proceso de ajuste de la producción se realiza considerando que las empresas carecen de información completa sobre el comportamiento de sus competidoras. En este contexto, suponiendo la intención cooperativa como factor fundamental, se alcanzan...

This paper considers a two-stage oligopoly model with downstream retailers and two types of transaction costs (in contracting retailers and in direct retailing). Our analysis shows how transaction costs affect vertical integration in a strategic model of oligopoly, and it relates transaction...

This paper studies the symmetric equilibria of a two-buyer, two-seller model of directed search in which sellers commit to information provision. More informed buyers have better differentiated private valuations and extract higher rents from trade. When sellers cannot commit to sale mechanisms,...

We study mass customization in a duopoly game in which the firms' products have different qualities. Whether customization choices are made simultaneously or sequentially is endogenously determined. Specifically, the customization stage of the game involves two periods. Each firm either selects...

In this paper we study the problem of price competition and free entry in congested markets. In particular, we consider a network with multiple origins and a common destination node, where each link is owned by a firm that sets prices in order to maximize profits, whereas users want to minimize...

A buyer procures a network to span a given set of nodes; each seller bids to supply certain edges, then the buyer purchases a minimal cost spanning tree. An efficient tree is constructed in any equilibrium of the Bertrand game.

This paper (a) characterizes the unique Nash equilibrium of the unidirectional Hotelling–Downs game in which firms maximize their market shares, for any distribution of the consumers, and (b) analyzes equilibrium behavior in the variation of the game in which each firm aims to secure a larger...

Emerging literature explores experimental platform selection games. These games converge rapidly on the superior platform under a wide range of conditions. We replicate the remarkable results of Hossain and Morgan (2009) in which such a game tips almost perfectly to the superior platform. Next,...

We study a set of bilateral Nash bargaining problems between an upstream input supplier and several differentiated but competing retailers. If one bilateral bargain fails, the supplier can sell to the other retailers. We show that, in a disagreement, the other retailers' behavior has a dramatic...
