The Patentatlas by Greif and Schmiedl (2002) represents an important source for patent data in Germany. Its use for industry-specific studies is however problematic because the correct assignment of patent data classified by technological fields to commonly used industry classifications is unclear. This paper presents an application-oriented approach to this issue. In using industryspecific R&D...

The theoretical framework of urban and regional economics is built on transportation costs for manufactured goods. But over the twentieth century, the costs of moving these goods have declined by over 90% in real terms, and there is little reason to doubt that this decline will continue. Moreover, technological change has eliminated the importance of fixed infrastructure transport (rail and wat...

This paper provides detailed information about spatial interactions in the job creation process in West German regional labor markets. We investigate spatial (auto-) correlations in the matching process of vacancies and unemployed, examine regional hiring patterns, and identify clusters of regions with intense inter-regional matching. An extensive specification analysis illustrates the extent o...

In many developing countries, agriculture hires at least as many workers as manufacturing industries. We investigate an economic geography model in which agricultural goods are costly to transport and in which manufactures hire labor from the local agricultural sector as unskilled labor. Our conclusions show that the parameters in the agricultural sector are crucial to determine the spatial con...

The paper studies the optimal distribution of business and residential land in a circular city. Once the optimum is characterized, we analyze the effect of changes in commuting costs and externality parameters. We also propose policies like labor subsidies, land taxes and zoning restrictions that can implement the efficient allocation as an equilibrium, or close the gap between the optimal and ...

Regional Dependencies in Job Creation: An Efficiency Analysis for Western Germany This paper investigates the efficiency of the matching process between job seekers and vacancy posting firms in West-Germany, using variation across labor market regions and across time. The results of a stochastic frontier analysis shed new light on extent and regional differences of search frictions, on potentia...

We use new data on the location and background of entrants into the US tyre industry to analyse why the industry became so regionally concentrated around Akron, Ohio, a small city with no compelling advantages for tyre production. We analyse where the Ohio entrants originated and conduct various analyses of how proximity to other tyre firms affected the longevity of tyre producers. We also exam...

UN Interventions: The Role of Geography This paper argues that UN military interventions are geographically biased. For every 1,000 kilometers of distance from the three Western permanent UNSC members (France, UK, US), the probability of a UN military intervention decreases by 4 percent. We are able to rule out several alternative explanations for the distance finding, such as differences by co...

Article history: Received 16 September 2010 Received in revised form 22 December 2010 Accepted 5 January 2011 Available online 12 January 2011 Seaports have historically played a key role in facilitating trade and growth. This paper is the first attempt in the literature to analyse the formation of Chinese seaport cities and the dynamics that drives it. First, we aim to identify theoretically t...

This paper analyzes the evolution of Chinese urban income distribution across space and time in post-reform era. Our results suggest no evidence on income convergence across cities during the period 1984-2003. We find that cities with comparable income level are likely to be co-located in the same region; further, cities tend to mirror the mobility of their counterparts located in the same prov...
