New economic geography focuses on the impact of falling transport costs on the spatial distribution of activities. However, it disregards the role of technological innovations, which are central to modern economic growth, as well as the role of migration costs, which are a strong impediment to...

We study decentralized and optimal urbanization in a simple multi-sector model of a rural-urban economy focusing on productivity differences and internal trade frictions. We show that even in the absence of the typical externalities studied in the literature, such as agglomeration, congestion or...

We propose a model where imperfect matching between firms and workers on local labor markets leads to spatial agglomeration. We show that the occurrence of spatial agglomeration depends on initial size differences in terms of both number of workers and firms. We analyse the effect of different...

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...

In this paper we find evidence that the new economic geography approach is able to describe and explain the spatial characteristics of an economy, in our case the German economy. Using German district data we estimate the structural parameters of a new economic geography model as developed by...

Border regions and border effects currently attract a lot of attention in political practice and economic research. Substantial interest in regions located along the frontiers of integrating countries is predominantly inspired by the presumption that their specific geographic position might...

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 analyses in the framework of a 2-region economic geography model the impact of transfers on agglomeration of economic activity. Two main results can be derived: First, subsidies to the activity of firms are more efficient to avoid agglomeration than subsidies to consumers (social...

It is uncertain whether the fundamental 'home market effect' (HME) generalizes from a two-country model to a more realistic setting with multiple countries. We present a three-country version of the seminal model by Krugman (1980) and analyse under which circumstances the HME is present once...
