Entrepreneurial activity is significantly predicted by the presence of other entrepreneurs in the residential neighborhood. One plausible source of such spatial clustering is local peer effects, where individuals’ decisions to become entrepreneurs are influenced by entrepreneurial neighbors....

This paper provides a conceptual discussion of relatedness, which suggests a focus on individuals as a complement to firms and industries. The empirical relevance of the main arguments are tested by estimating the effects of related and unrelated variety in education and occupation among...

We document and then develop a model explaining and relating changes in firms'' organisation and in urban structure. Sharing of business services by headquarters and of sector-specific intermediates by production plants within a city reduces costs, while congestion increases with city size. A...

This paper outlines a new approach for analysing the role of trade in promoting industrial development. It offers an explanation as to why firms are reluctant to move to economics with lower labour costs, and shows how trade liberalisation can change the incentives for firms to locate in...

We analyze the geographic scale at which density externalities operate and their attenuation with distance. Using square grid data at a fine spatial resolution, we find that a doubling of neighborhood density, measured as the density of 1 km2 squares, yields an increase in the overall wage-level...

We analyze the influence of market thickness for skills on initial wages and subsequent wage development of university graduates. Using Swedish micro-level panel data on a cohort of graduates, we show that two out of three graduates move to large cities upon graduation. Large cities yield higher...

Zipf’s law is one of the best-known empirical regularities in urban economics. There is extensive research on the subject, where each city is treated symmetrically in terms of the cost of transactions with other cities. Recent developments in network theory facilitate the examination of an...
