TL;DR: In this paper, the authors used a new data set on the growth of large industries in 170 U.S. cities between 1956 and 1987 and found that local competition and urban variety, but not regional specialization, encourage employment growth in industries.

TL;DR: This article found that most indicators of institutional quality used to establish the proposition that institutions cause growth are constructed to be conceptually unsuitable for that purpose and also found that some of the instrumental variable techniques used in the literature are flawed.

TL;DR: In this paper, the authors present a model where social interactions create enough covariance across individuals to explain the high cross-city variance of crime rates, and compare the degree of social interaction across crimes, across geographic 1 units and across time.

TL;DR: The authors discusses the prevalence of Silicon Valley-style localizations of individual manufacturing industries in the United States Several models in which firms choose locations by throwing darts at a map are used to test whether the degree of localization is greater than would be expected to arise randomly and to motivate a new index of geographic concentration.
