This paper is concerned with the influence of agglomeration economies on economicoutcomes across British regions. The concentration of economic activity in one place canfoster economic performance due to the reduction in transportation costs, the readyavailability of customers and suppliers, and...

We identify the impact of local firm concentration on incumbent performance with a quasi natural experiment. When Germany was divided after World War II, many firms in the machine tool industry fled the Soviet occupied zone to prevent expropriation. We show that the regional location decisions...

The analysis of patent and citation data has become a popular source of evidence on localizedknowledge spillovers and innovation. Nevertheless, an aspect has been overlooked: the patentdistribution across inventors is extremely skewed, as many inventors register one or a fewpatents, while a...

We analyze the economic impact of the German high-speed rail (HSR) connecting Cologne and Frankfurt, which provides plausibly exogenous variation in access to surrounding economic mass. We find a causal effect of about 8.5% on average of the HSR on the GDP of three counties with intermediate...

An inflow of immigrants into a region affects house prices in three ways. In the short run, housing demand increases due to the increase in foreign-born population. In the long run, immigrants affect native location decisions and housing supply conditions. Previous research on the effect of...

This paper investigates the impact of technological change on local labour market outcomes in Britain. Using a newly assembled panel database for the period 2000-2007 and a directly observed measure of technological change based on patent records, the analysis suggests that employment levels are...

This paper estimates the effects of road construction on individual labour market outcomes using micro-data from Great Britain between 2002 and 2008. To capture these effects, I use a measure of accessibility to employment through the road network at a very detailed geographical level. I test...

This paper estimates the impact of road improvements on firm employment and productivity using plant level longitudinal data for Britain. Exposure to transport improvements is measured by changes in employment accessibility along the road network. These changes are constructed using data on...

We provide empirical evidence on the role of labour market pooling in determining thespatial concentration of UK manufacturing establishments. This role arises because largeconcentrations of employment iron out idiosyncratic shocks and improve establishments'ability to adapt their employment to...

Empirical studies consistently report that labour productivity and TFP rise with city size. The reason is that cities attract the most productive agents, select the best of them, and make the selected ones even more productive via various agglomeration economies. This paper provides a...
