An exhaustible stock of resources may be exploited by N players. An arbitrarily long duration of the game is only possible, if the utility function satisfies certain restrictions at small values R of extraction. We find that stability against unilateral defection occurs if the elasticity of the...

This paper examines how trade liberalization affects the innovation incentives of firms, and what this implies for industry productivity and social welfare. For this purpose we develop a reciprocal dumping model of international trade with heterogeneous firms and endogenous R&D. We identify two...

This paper studies why multinational firms often share ownership of a foreign affiliate with a local partner even in the absence of government restrictions on ownership. We show that shared ownership may arise, if (i) the partner owns assets that are potentially important for the investment...

This paper discusses the issue of competitiveness and environmental regulation from the viewpoint of strategic environmental policy models. It demonstrates that the incentive for strategic policies is determined only by the reaction of the opponent. Furthermore, it shows that the conditions...

This paper discusses environmental policies which aim at a sustainable use of domestic resources which are mobile. It assumes that one country introduces such a policy but the other country does not. If a resource is mobile, strict domestic environmental policies may increase the resource...

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 sheds some light on the possible implications of compensations which are paid for the maintenance of an environmental stock. It shows that serious complications can arise if the resource-owner can vary the compensation price. In that case, extraction-driven stock preservation policies...

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...

The Earth Summit in Rio was expected to pave the way for more and effective cooperation with respect to biodiversity. This paper discusses the approaches which were adopted at the summit and the benefits of biodiversity which are closely related to innovations of the biotechnology industries....
