This paper presents a game where the incumbent firm uses the price as a signal about demand size. Without observing the demand, the regulator has to decide if the entry of new firms will be allowed. The game has a pooling Perfect Bayesian Equilibrium in which the incumbent firm chooses the...

In this paper we compare the costs of two regulatory policies about the entry of new firms. We consider an incumbent firm that has more information about the market demand than the regulator. Then, the incumbent firm can use this advantage to persuade the regulator to make entry more difficult....

We introduce asymmetric information about consumers' transportation costs (i.e., the degree of product differentiation) in the model of Hotelling (1929). When the transportation costs are high, both firms have lower profits than in the case of perfect information. Contrarily, both firms may...

This critical review focuses on the development of spatial competition models in which the location choice by firms plays a major role. Therefore, after a brief review of the roots of spatial competition modeling, this paper intends to offer a critical analysis over its recent developments. The...

In this paper, by using a database of Portuguese and Brazilian firms, where the Latin Corporate Governance Model is traditionally predominant but increasingly out of fashion, we investigate whether the Latin Corporate Governance Model performs worse or better than others (variants of the...

We consider a duopoly with horizontally differentiated firms, where firms decide the long-term plans (locations) in addition to short-term issues (prices). As in Bárcena-Ruiz and Casado-Izaga (2014), we introduce a third entity in the city by considering the presence of a policymaker that...

This paper builds on a duopoly with horizontally differentiated firms, where firms simultaneously decide the long-term plan (location) in addition to the short-term issue (price). As in Bárcena-Ruiz and Casado-Izaga (2014), we introduce a third entity in the city by considering the presence of...

We study the effects of cooperative wage setting in industries that use two different types of labor. In particular, we consider a two-stage game where firms hire non-specialized workers in a perfectly competitive labor market and specialized workers that are more productive and expensive, but...

We develop a model that is a synthesis of the two-sided markets duopoly model of Armstrong (2006) with the nested vertical and horizontal dierentiation model of Gabszewicz and Wauthy (2012), which consists of a linear city with dierent consumer densities on the left and on the right side of the...

We characterize collusion sustainability in markets where demand growth may trigger the entry of a new firm whose efficiency may be different from the efficiency of the incumbents. We find that the profit-sharing rule that firms adopt to divide the cartel profit after entry is a key determinant...
