This paper focuses both on the competition process and the firms liability in environmental protection and the demonstration is made by comparing two models of safety investment. The rst one shows sensitive players to their environmental liability: they seek to minimize the technologies accident...

We present a theoretical model in tourism economics, assuming that the market for tourism is an oligopoly with differentiated products. Destinations (i.e., countries, regions, sites or even firms) can invest in order to improve their carrying capacity that can be interpreted as the stock of...

This paper studies the relevance of strategic trade effects in the environmental policy for the European electricity sector. The production, investment and trade of electricity are modelled for four European countries. Three market regimes are distinguished: perfect competition, price regulation...

The paper studies how does the size of a cartel affect the possibility that its members can sustain a collusive agreement. I obtain that collusion is easier to sustain the larger the cartel is. Then, I explore the implications of this result on the incentives of firms to participate in a cartel....

In view of the uncertainty over the ability of merging firms to achieve efficiency gains, we model the post-merger situation as a Cournot oligopoly wherein the outsiders face uncertainty about the merged entity's final cost. At the Bayesian equilibrium, a bilateral merger is profitable provided...

Taking account of sinks credits as agreed in Bonn and Marrakech, this paper illustrates how market power could be exerted in the absence of the US ratification under Annex 1 trading and explores the potential implications of the non-competitive supply behavior for the international market of...

There are more and more industries in which firms are specialized in the production of a component of the final good. This is especially true in high-tech industries. The basic question is why don't these firms merge ? We paradoxically show that industries which are typical candidates for...

In a duopoly industry with environmentally differentiated products, we examine the effects of introducing a mandatory environmental quality standard on firms' environmental quality choices, profits, and the average environmental quality offered by the industry. We show that at low standard...

We develop a product-differentiated model where the product space is a network defined as a set of varieties (nodes) linked by their degrees of substitutability (edges). We also locate consumers into this network, so that the location of each consumer (node) corresponds to her “ideal”...

In this paper we look at both the theoretical and empirical behaviour of price-cost margins when capital market imperfections affect firms' markup policies. We present a model of a firm operating in an industry with differentiated products and facing imperfect markets for financing operations....
