Recent theories of economic growth, including Romer (1986), Porter (1989) and Jacobs (1969), have stressed the role of technological spillovers in generating growth.

We investigate the effects of the recently constructed Chinese national highway system on local economic outcomes. On average, roads that improve access to local markets have small or negative effects on prefecture economic activity and population. However, these averages mask a distinct pattern...

Since 1980, US wage growth has been fastest in large cities. Empirically, we show that most of this urban-biased growth reflects wage growth at large Business Services firms, which are also the most intensive users of information and communications technology (ICT) capital in the US economy. We...

This paper analyzes how changes in the concentration of political power affect long-run development. We study Brazil's military dictatorship whose rise to power dramatically altered the distribution of power of local political elites. We document that municipalities that were more politically...
