In this paper, we study the problem of licensing cost-reducing innovations in a duopoly under supply function competition. We show that the innovator prefers fixed-fee licensing to no licensing if its cost advantage is not extremely large. Moreover, if its cost advantage is not extremely small,...

A Portuguese translation of this paper, with the title "Controle Estrangeiro e Concentraçao na Indústria Brasileira", was published in IPEA’s journal Pesquisa e Planejamento Econômico, April 1987, pp. 161-189. This working paper, in English, was part of the proceedings of the annual...

In the framework Hotelling-Downs competition two players can freely choose a position along a one-dimensional market. We introduce restrictions of feasible strategies and analyze the consequences for players and consumers. In equilibrium players may minimally differentiate away from the center...

In order to fight collusive behaviors, the best scenario for competition authorities would be the possibility to analyze detailed information on firms' costs and prices, being the price-cost margin a robust indicator of market power. However, information on firms' costs is rarely available. In...

This paper considers the relative efficiency of unit tax and ad valorem tax in Cournot doupoly in the presence of licensing opportunities after the announcement of the tax rates by the government. Anderson et al. (2001) shows that in such a case ad valorem tax welfare dominates the unit tax....

We show that the standard analysis of vertical relationships transposes directly to investment dynamics. Thus, when a firm undertaking a project requires an outside supplier (e.g., an equipment manufacturer) to provide it with a discrete input to serve a growing but uncertain demand, and if the...

Based on the approaches of mesoeconomics, institutional theory, game theory and active systems theory, a set of models has been developed that allows us to study the influence of the structure of agents' relationships in socio-economic systems on their activities and performance. The general...

Using a duopoly model with symmetric retailers, we show that retailer strategies regarding opening hours and quality choices of goods vary depending on the cost structure of the quality investment in goods. In the case of the cost remaining constant regardless of the length of opening hours, a...

This paper analyzes the effects of a stronger patent regime on innovation incentives, patenting propensity and scientist mobility when an innovating firm can partially recover its damage due to scientist movement from the infringing rival. The strength of the patent system, which is a function...

The paper extends the analysis of price competition among capacity-constrained sellers beyond the cases of duopoly and symmetric oligopoly.We first provide some general results for the oligopoly and then focus on the triopoly, providing a complete characterization of the mixed strategy...
