In this paper we describe the development of regional specialisation and geographical concentration in Germany between 1993 and 2001. Somewhat contrary to theoretical expectations derived from the recent literature in location theory, we neither find compelling evidence for a specialisation...

The global welfare implications of home market effects in trade models with imperfect competition are little understood. This paper proposes a simple model in which such implications can be easily analyzed. It shows an overall tendency of imperfectly competitive sectors to inefficiently cluster...

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...

This paper proposes the question whether or not traveling expenses to work should be deductible from the income tax base. In order to answer this question, a simple model of (im-) perfect household and worker mobility is employed. The focus of the analysis is on the efficient use of land and the...

Based on 1182 dyads of German new ventures and venture capitalists involved in a financing round between 2002 and 2007, we examine the impact of spatial proximity on the likelihood of an investment. We find that with each triplication of journey time the relative likelihood of an investment...

Verschiedene Verbindungen zwischen lokalen Kapitaleinheiten können Komplementaritäten in den Standortentscheidungen begründen: Skalenerträge und Spillovereffekte, Input- Output-Beziehungen bei Transportkosten und EinkommenskreislaufefTekte. In einem stilisierten Modell wird ihr simultaner...

This paper analyses the effect on agglomeration tendencies of allowing firms to become multi-region firms in a standard model of trade and location. More specifically, we introduce horizontal and vertical multi-region firms into the core-periphery (CP) model developed by Krugman (1991). The...

In this paper, location choices are driven by households (both blacks and whites) consciously choosing to trade off proximity to neighbors of similar racial backgrounds for proximity to jobs. Because of coordination failures in the location choices, multiple urban equilibria emerge. There is a...

An analytically solvable model of new economic geography is developed. Acquisition of skills is costly for workers but it allows them to earn wages that are larger than those of the unskilled. Moreover, skills acquisition can be subsidized by a regional government. For large transport costs,...

People spend a lot of time commuting and often find it a burden. According to economics, the burden of commuting is chosen when compensated either on the labor or on the housing market so that individuals? utility is equalized. However, in a direct test of this strong notion of equilibrium, we...
