The paper outlines a static equilibrium model, which analyses the economic development in a two-country case by considering interregional migration in R&D-sectors. The effects of migration and firm decisions on both industrial agglomeration and economic development will be shown: lock-in-effects...

We analyze the distribution of economic activity across space for different types of activity and different levels of aggregation. Not only is this distribution highly uneven (independently of the type of activity and level of aggregation), it is also remarkably regular regarding its size...

In an empirical analysis, considering 236 U.S. cities in the period 1980-1990, we document a strong positive correlation between local supply of skills and their return. In SMSA's where the average education of workers is high the education premium is also high. This is true both considering the...

Identification of the strength of human capital externalities at the aggregate level is still not fully understood. The existing method may yield positive or negative externalities even if wages reflect marginal social products. We propose an approach that yields positive average human capital...

Two innovations in the last century have changed dramatically the cost of communicating and transmitting information: The first is the widespread adoption of telephony; the second is the internet. We study the implications of these changes in ICT for urban structure. We find robust evidence that...

Success in international trade depends, amongst other things, on distance from markets. Most new economic geography models focus on the distance between countries. In contrast much less theorizing and empirical analysis have focused on how distances within a country for instance due to the...

This paper investigates the effects of labor market integration, in the form of worker mobility, in a model with long-term labor contracts that lead to wage rigidities and unemployment. Reflecting the interdependence of regional labor markets, we develop a general-equilibrium framework where the...

A central feature of many models of location choice -- whether of firms or households, within or across cities -- is the role of local interactions or spillovers, whereby the payoffs from choosing a location depend in part on the number or attributes of other individuals or firms that choose the...

With the growing recognition of the role played by geography in all sorts of economic problems, there is strong interest in measuring the size and scope of local spillovers (i.e., simple anonymous agglomeration or congestion effects, or more complicated interactions between individuals or firms...
