We set up a simple dynamic macroeconomic model with (i) polluting consump- tion and a preference for a clean environment, (ii) increasing returns in abatement giving rise to an EKC and (iii) sustained growth resulting from a linear final-output technology. The model captures two sorts of market...

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...

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...

In macroeconomic dynamic models the speed at which output converges to its steady state is of outstanding interest. Theoretical investigations usually focus on the asymptotic speed of convergence only. This procedure is, however, unnecessarily restrictive and hides important information. The...
