The paper examines the impact of communication cost reductions on growth and welfare by means of an endogenous spatial growth model. Policy makers having to decide upon transport policies often claim certain policies such as infrastructure investments to have growth stimulating effects that...

We consider a carbon emissions tax announced today, but implemented after a known time-lag. Before implementation, the announcement induces higher emissions than without intervention. In welfare terms, this adverse announcement effect could more than outweigh the gain after tax implementation....

Gegenstand der Regionalökonomik sind die Verteilung der ökonomischen Aktivität, die Austauschbeziehungen sowie differenzierte Wachstums- und Schrumpfungsprozesse im geographischen Raum. Die positive Theorie erklärt, warum sich aus rein ökonomischen Gründen Agglomerationen auf der einen und...

Die - auf Überlegungen Alonsos basierende - Stadtökonomik analysiert urbane Räume, erklärt deren innere Struktur und betrachtet die Ursachen für die Stadtbildung.

We develop an overlapping generations endogenous growth model with stocks of produced capital, human capital, a non-renewable resource, and irreversibly accumulated greenhouse gases in deterministic and stochastic versions. The model allows for analyzing different elasticities of substitution....

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...

This paper studies the spatial impact of two main aspects of European transport policy, namely infrastructure investments and pricing. In its "White Paper: European Transport Policy for 2010: Time to Decide" the European Commission has laid down a comprehensive programme of transport policy...
