Integration affects economic growth mainly through two different channels : The scale-effect channel and the factor-reallocation channel. In order to investigate both channels within a unifying framework, we employ a simple descriptive growth model. The scale-effect channel increases either the...

Production often causes pollution as a by-product. Once environmental degradation becomes too severe, regulation is introduced by which society forces the economy to make a transition to cleaner production processes. We model this transition as a change in "general purpose technology" and...

This contribution provides evidence for the hypothesis that trade increases growth through its curbing effect on capital taxes. The analysed mechanism includes two different steps and considers the critical points of both the theoretical and empirical studies in this field. In particular, the...

We derive the optimal contributions to global climate policy when countries differ with respect to income level and pollution intensity. Countries' growth rates are determined endogenously, and abatement efficiency is improved by technical progress. We show that country heterogeneity has a...
