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...

This paper demonstrates that partial cooperation with respect to the use of an international environmental resource can emerge when countries are able to opt to breach an agreement. Although the option of non-compliance restricts the set of coalitions on those which embrace merely two members,...

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...

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...

In diesem Papier beschäftigen wir uns mit den Möglichkeiten einer globalen Umweltpolitik, die eine Minderung der CO2-Emissionen zum Ziel hat. Wir konzentrieren uns hierbei auf die im Rahmen des joint-implementation- Ansatzes in die Diskussion eingebrachten Vorschläge und diskutieren diese am...

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...

This paper shows that in-kind-transfers are an effective instrument to stabilize agreements when compliance cannot be guaranteed. It demonstrates the weak superiority of in-kind-transfers for a unilateral relationship between two agents. In particular, it proves that, under conditions of perfect...

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...

In an international setting, sovereignty of countries imposes serious problems on compliance and participation for a multilateral environmental agreement. This paper discusses both problems simultaneously in a three-country-setting. It employs a repeated-game-model and develops some basic...

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...
