This paper relaxes the Motta & Vasconcelos’ (2005) short-term assumption that firms’ capital is fixed. We demonstrate that, contrary to the conclusion of that article, in the best interest of consumers, even when firms have large economies of scale, long-term forward-looking Antitrust...

We propose a profit-sharing rule that maximizes sustainability of cartel agreements. This rule is such that the critical discount factor is the same for all the firms. If a cartel applies this rule, then asymmetries among firms may not hinder collusion (contrarily to the typical finding in the...

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...

Despite the major concern of the competition authority to forbid and prosecute formal cartels who cooperatively fix prices, limit production or divide markets, there seems to be little regulation and investigation of collusive practices in the labor market. For that reason, this article analyzes...

This article focuses on the location decision of firms when competing in a spatial Cournot duopoly. Our original contribution is that firms are dependent on a natural resource input, which is assumed to be located in one of the extremes of the market, to be able to produce the output sought by...

In a two-sided market duopoly, we investigate the effects of delegating long run restrictive and unrestrictive decisions to managers by the platforms' owners, the effects of the platforms' ownership establishing long run decisions without managers and the impacts of asymmetric regimes between...

We develop a duopoly price competition model that establishes a link between the recent literature of two-sided markets and behavior economics. We fully characterize the subgame perfect Nash equilibrium, which depends on the level of …xed costs. Moreover, introducing discrimination between the...

We study competition between two shopping centers (department stores or shopping malls) located at the extremes of a linear city. In contrast with the existing literature, we do not restrict consumers to make all their purchases at a single place. We obtain this condition as an equilibrium...

We study the effect of quadratic differentiation costs in the Hotelling model of endogenous product differentiation. The equilibrium location choices are found to depend on the magnitude of the differentiation costs (relatively to the transportation costs supported by consumers). When the...

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...
