The literature on the wage curve provides considerable evidence in favor of a negative relationship between unemployment and wages. It is thus often seen as a refutation of the Harris-Todaro model, who point to a positive relationship. This paper shows that both strands of literature are special...

During the last year, the research field of spatial economic has rapidly increased. There is consensus that the economic performance of a region depends not only on its own potential, but also on the development of their neighbouring regions. Knowledge spillovers, which are non constant over...

This paper extends an economic geography model by tariffs to analyze their impact on welfare and sustainability of agglomerations. Policies with and without cooperation are compared, with the goal of maximizing aggregated welfare in the former and regional welfare in the latter case. The main...

This paper presents a simple framework in which the location and the growth rate of economic activities are endogenous and interact. We show that the nature of the equilibrium and of the relation between growth and location depends fundamentally on whether capital is assumed to be mobile (in...

We discuss theoretical approaches to study the relationship between the size distribution of a nation's cities and macroeconomic growth. The discussion is based on the hypothesis of the New Growth Theory that inter-personal spillovers of education and skills determine the long-run growth of the...

Standortwettbewerb der Bundesländer ist prinzipiell eine gute Sache. Er bringt Effizienzgewinne, Kosteneinsparungen, verbesserte Leistungsangebote durch Konkurrenzdruck und präferenzgerechtere öffentliche Institutionen. Aber er kann dies nur, wenn es zu einem wirklichen Wettbewerb kommt....

This paper focuses on tax competition and international migration in R&D sectors as agglomeration forces and trade restrictions are present. Economic integration forces industrialized countries to adapt their tax rates in order to keep their industrial status quo. Unlike the often discussed...

Compensation schemes in which land owners receive payments for voluntarily managing their land in a biodiversity-enhancing manner have become one of the most important instruments for biodiversity conservation worldwide. One key challenge when designing such schemes is to account for the spatial...

This paper studies urban sustainability from the perspective ofexternalities. We develop a general spatialequilibrium model of a monocentric city, in which two types ofexternalities occur. On the one hand, pollution inthe industrial centre leads to a spatially differentiateddeterioration of the...
