We set up a dynamic stochastic model of a stylized economy comprising a final output sector (with traditional and modern firms) and an intermediate goods sector. It is shown that market integration reduces the volatility of the rate of return of capital invested in modern firms. The induced...

Climate economics has been criticized for ignoring uncertainty, catastrophic changes, and tipping points (Stern 2016). The present paper addresses these issues. We consider multiple climate shocks which are recurring, random, uninsurable, and potentially large. The associated damages and the...

Standard environmental economics prescribes policies which are optimal and implemented immediately. The paper argues that, in reality, environmental policy often deviates from the optimum and implementation is not deterministic but subject to major uncertainty and frequent change. We present a...

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...

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

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

In diesem Beitrag werden die Auswirkungen einer wirtschaftlichen Integration auf das langfristige Wachstum analysiert. Dabei wird von international unterschiedlichen Faktorausstattungen, einer unvollständigen Wissensdiffusion und der Existenz von Umweltproblemen ausgegangen. Als Resultat einer...
