Carbon taxes remain economists favoured policy tool to curb emissions, but are unpopular among segments of the populations. Theoretical and numerical work tends to show the effectiveness of carbon taxes, but ex-post empirical analyses are still rare. In this paper we attempt to bridge this gap....

The paper develops a model with non-exponential population growth, nonrenewable natural resources, and endogenous knowledge creation to analyse substitution between primary inputs and an essential use of resources in the innovation sectors, which is generally considered as most unfavourable for...

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"...

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...
