Recent research has shown that industries that locate together in space also move together over the business cycle, and that this correspondence between spatial and temporal comovement is important to aggregate volatility. This paper asks whether this correspondence is due to local common shocks...

Will improvements in information technology eliminate face-to- face interactions and make cities obsolete? In this paper, we present a model where individuals make contacts and choose whether to use electronic or face-to-face meetings in their interactions. Cities are modeled as a means of...

For a variety of reasons described in the paper, improving the performance of urban school districts is more difficult today than it was several decades ago. Yet economic and social changes make performance improvement especially important today. Two quite different bodies of research provide...

We study how an aggregate bank flow shock impacts German cities' GDP growth depending on the state of their local real estate markets. Identification exploits a policy framework assigning refugees to cities on a quasi-random basis and variation in non-developable area for the construction of a...

This paper shows that the products and prices offered in markets are correlated with local income-specific tastes. To quantify the welfare impact of this variation, I calculate local price indexes micro-founded by a model of non-homothetic demand over thousands of grocery products. These indexes...

In the United States in the 19th and early 20th centuries, there was a substantial mortality 'penalty' to living in urban places. This circumstance was shared with other nations. By around 1940, this penalty had been largely eliminated, and it was healthier, in many cases, to reside in the city...

GDP growth is often measured poorly for countries and rarely measured at all for cities or subnational regions. We propose a readily available proxy: satellite data on lights at night. We develop a statistical framework that uses lights growth to augment existing income growth measures, under...

Covid-19 is the single largest threat to global public health since the Spanish Influenza pandemic of 1918-20. Was the world better prepared in 2020 than it was in 1918? After a century of public health and basic science research, pandemic response and mortality outcomes should be better than in...

In the context of interwar Poland, we find that Jews tended to be more literate than non Jews, but show that this finding is driven by a composition effect. In particular, most Jews lived in cities and most non-Jews lived in rural areas, and people in cities were more educated than people in...

Urban economics has traditionally viewed cities as having advantages in production and disadvantages in consumption. We argue that the role of urban density in facilitating consumption is extremely important and understudied. As firms become more mobile, the success of cities hinges more and...
