Because of large economic and environmental asymmetries among world regions and the incentive to free ride, an international climate Regime with broad participation is hard to reach. Most of the so far proposed Regimes base on an allocation of emission rights that is to be perceived as fair....

The policy instruments for emissions reductions will be an integral part of a Post Kyoto Climate Regime. In this paper we compare a harmonized international carbon tax to a cap and trade system with different allocation rules for the emission caps. The caps are based either on the requirement...

National labour market institutions interact across national boundaries when product markets are global. Labour market policies can thus entail spill-overs, which suggests that there are benefits from international policy coordination. This paper studies the effects of wage subsidies in an...

This paper sets up a multiregional dynamic framework by combining the optimal savings model with investment adjustment costs and the spatially disaggregated model with Dixit-Stiglitz structure in the modern sector. Because of increasing product diversity on the dynamic equilibrium path, the...
