This study empirically establishes a link between medieval trade, agglomeration and contemporary regional development in ten European countries. It documents a statistically and economically significant positive relationship between prominent involvement in medieval trade and commercial...

We examine "agglomeration shadows" that emerge around large cities, which discourage some economic activities in nearby areas. Identifying agglomeration shadows is complicated, however, by endogenous city formation and "wave interference" that we show in simulations. We use the locations of...

Standard approaches to studying industrial agglomeration have been in terms of scalar measures of agglomeration within each industry. But such measures often fail to distinguish spatial scales of agglomeration. In a previous paper, Mori and Smith (2014) proposed a pair of quantitative measures...

The paper quantifies the impact of agglomeration economies on the clustering of German firms. Therefore, I use the 2006 Innobarometer survey, which focuses on cluster characteristics and activities of German firms, to empirically identify agglomeration economies derived from the New Economic...

The current debate on polycentric urban development suggests that inter-firm relations are important for the creation and sustainment of urban networks. Conceptually, the degrees of spatial and functional integration and urban complementarities in economic network relations are hypothesised to...

We estimate the effects of industrial localization on the spatial persistence of employment in the software industry. Locations with an initial concentration of software employment retain an excess number of employees, beyond that expected from job turnover and job persistence at the...
