Where does adaptation to innovation take place? The supply of educated workers and local industry structure matter for the subsequent location of new work - that is, new types of labor-market activities that closely follow innovation. Using census 2000 microdata, the author shows that regions...

Does social distancing harm innovation? We estimate the effect of non-pharmaceutical interventions (NPIs)—policies that restrict interactions in an attempt to slow the spread of disease—on local invention. We construct a panel of issued patents and NPIs adopted by 50 large US cities during...

In this paper, I study long-run population changes across U.S. metropolitan areas. First, I argue that changes over a long period of time in the geographic distribution of population can be informative about the so-called \resilience" of regions. Using the censuses of population from1790 to...

We present theory and evidence highlighting the role of natural amenities in neighborhood dynamics, suburbanization, and variation across cities in the persistence of the spatial distribution of income. Our model generates three predictions that we confirm using a novel database of...

The California correctional system is undergoing a dramatic transformation under Assembly Bill 109 (“Realignment”), a law that shifted responsibility from the state to the counties for tens of thousands of offenders. To help manage this change, the state will distribute $4.4 billion to the...

Where does adaptation to innovation take place? The author presents evidence on the role of agglomeration economies in the application of new knowledge to production. All else equal, workers are more likely to be observed in new work in locations that are initially dense in both college...
