This paper discusses the issue of competitiveness and environmental regulation in a dynamic framework. It presents an example and a general model. It is shown that the dynamic framework cannot lend general support to the hypothesis that strict environmental policies result in an increase in...

This paper discusses a simultaneous market entry game between two firms with different fixed costs. This case is a typical application of mixed strategy equilibria. Conventional wisdom would suggest that the low-cost firm is more likely to enter the market. This presumption is wrong. Instead,...

This paper demonstrates that the Bertrand paradox does not hold if cost functions are strictly convex. Instead, multiple equilibria exist which can be Pareto-ranked. The paper shows that the Pareto-dominant equilibrium may imply profus higher than in Cournot competition or may even sustain...

Markov perfection has become the usual solution concept to determine the non-cooperative equilibrium in a dynamic game. However, Markov perfection is a stronger solution concept than subgame perfection: Markov perfection rules out any cooperation in a repeated prisoners' dilemma game because the...

This paper questions the standard results of an international noncooperative reduction game through considering scope effects between reduction and adaptation policies. In particular, it demonstrates that scope effects can result in positively sloped reaction curves. The paper discusses also the...
