firms tend to choose locations that are symmetric around the point of highest density, and there can be no agglomeration. …

Traffic congestion alleviation has long been a common core transport policy objective, but it remains unclear under … (2001 to 2007). Using instrumental variables, results suggest that congestion slows job growth above thresholds of … congestion-induced travel delay impeding productivity growth. Results suggest that the strict policy focus on travel time savings …

This Paper estimates the agglomeration benefits that arise from vertical linkages between firms. The analysis is based … agglomeration benefits of the spatial variation in firm level nominal wages. Unusually detailed intermediate input data allow us to …

the aim of comparing the only two possible market outcomes, i.e. agglomeration and dispersion. More precisely, we use the … plausible values of the main parameters suggest that there might be excessive agglomeration. …

economic growth. We develop an empirical model that endogenizes both entrepreneurial activity and agglomeration effects on … expenditures, both entrepreneurial activity and agglomeration have a positive and statistically significant effect on technological …

equilibria: symmetric spreading, partial and full agglomeration. We show that the extent of agglomeration crucially depends on … between the extent of agglomeration and trade freeness that have been found in the literature. …

investigates the integration experience of external border regions, as well as the role of distance, market size and agglomeration …

This paper studies how firm heterogeneity in terms of productivity affects the balance between agglomeration and … endogenous markups. It shows that firm heterogeneity matters. However, whether it shifts the balance from agglomeration to … `evenness'. Accordingly, the role of firm heterogeneity in selection models of agglomeration can not be fully understood without …
