The stylized fact that the fraction of workers who are college graduates appears to increase more in US cities where the initial share is larger has attracted significant attention. Furthermore, more educated cities appear to grow faster. These two trends could portend the divergence of cities...

We introduce an index of urban amenities based on hotel night stays that can rank most U.S. metros in levels and changes for the years 1990 through 2015. This naive index can be used on its own to study changes in total amenity level or with other measures to reduce omitted variable bias....

This survey reviews the current state of the economic literature, assessing the impact of transport policies on growth, inclusion, and sustainability in a developing country context. The findings are summarized and methodologies are critically assessed, especially those dealing with endogeneity...

Bartik's (1991, 1993) approach to identifying shocks in demand to regional economies has been used extensively for nearly thirty years. We chronicle the development of Bartik-type shift-share instruments and examine the empirical performance of alternative versions that use different...

This survey reviews the current state of the economic literature, assessing the impact of transport investments and policies on growth, inclusion, and sustainability in a developing country context. It also discusses the specific implementation challenges of transport interventions in developing...

The ratio of skilled (college graduate) to unskilled (non-college graduate) workers (the skill intensity ratio, SIR) varies substantially across cities and the variance in the SIR has increased significantly since 1970. Recent research finds that the ratio of skilled to unskilled worker earnings...

This survey reviews the current state of the economic literature, assessing the impact of transport policies on growth, inclusion, and sustainability in a developing country context. The findings are summarized and methodologies are critically assessed, especially those dealing with endogeneity...

This paper studies how the changing geographic distribution of skilled workers in the US affects theoretical models that use Gibrat's law to explain the size distribution of cities. In the empirical literature, a divergence hypothesis holds that college share increases faster in cities where...
