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....

This paper deals with the impact of international capital mobility on labor taxes and the size of the public sector. It employs a model of the labor market, where national trade unions arc able to set wages above the competitive level. In a closed economy, a higher labor tax raises wage demands...

In a recent paper, Muthoo (1995) discusses whether the Rubinstein solution carries over on repeated bargaining situations. He concludes that stationary equilibria for such a repeated bargaining game do not imply the Rubinstein solution and that several non-stationary equilibria may exist. This...

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...

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 provides a rationale for taxing waste exports when closure risks are endogenous in that they depend on the importing country's accumulated stock of waste. The paper shows that the optimal time path of waste exports requires a progressively increasing tax rate which even surmounts a...

The probability that an agent takes a certain action or a certain event occurs depends often on the actions taken by some agents. If this probability depends not only on current actions but on the sum of all past actions, these stock-dependent risks imply an intertemporal effect. In the present...
