This paper analyses the evolution of the bidding strategies of nuclear power plants on the Spanish day-ahead auction market, over the 11-year period from 2002 until December 2012. During that time the proportion of renewable energy especially wind and solar power increased dramatically. At the...

We consider firms perfectly symmetrical on production costs in the pre-merger game but the cost of the merged entity may be amended due to the anti-competitive effects of the merger. The lack of empirical precision concerning the effect of the merger on production costs (Scherer, 1980 or Tichy,...

Despite the numerous researches about imperfect competition, the market power remains difficult to quantify using traditional economics methods. In this paper, we propose an experimental economics design and outline some ways of analysis of its results toward characterization of the use of...

In international emissions trading schemes such as the Kyoto Protocol and the European Union Emissions Trading Scheme, the suboptimal negotiation of the cap with respect to total pollution minimization leads us to critically examine the proposition that generous allocation of grandfathered...

Stemming from politically given market imperfections in a tradable permits system, this paper develops a Stackelberg game with two types of non-cooperative agents to describe how a large -potentially dominant- agent may exercise market power at the expense of a competitive fringe. In a dynamic...

This paper explores the rationale of price-taking and price-making behaviours in the context of Walrasian and Cournotian pure exchange economies. Beside the influence of the number of agents, we underline the role of the structure of preferences. Through three equilibrium variations of the same...

We try in this paper to characterize the state of mobile phone market in Tunisia. Our study is based on a survey of foreign experience (Europe) in detecting collusive behavior and a comparison of the critical threshold of collusion between operators in developing countries like Tunisia. The...

The sale of ideas (e.g. through licensing) facilitates vertical specialization and the division of labor between research and development. This specialization can improve the overall efficiency of the innovative process. However, these gains depend on the timing of the sale: the buyer of an idea...

This paper investigates the degree of competition in the WAEMU financial industry over the period 2002-2007 using firm-level data (591 year-firm observations). Market structure analysis, the Panzar-Rosse model and conjectural variation are applied to assess the level of competition. The results...

We present a Cournot model that compares the critical threshold of collusion in Duopoly and Oligopoly Markets where the actors are private, mixed or public. We assume that the incentive critical threshold for collusion depends on the interconnection fees. The different threshold values...
