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...

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...

We contrast evidence of urban path dependence with efforts to analyze calibrated models of city sizes. Recent evidence of persistent city sizes following the obsolescence of historical advantages suggests that path dependence cannot be understood as the medium-run effect of legacy capital but...

We examine portage sites in the U.S. South, Mid-Atlantic, and Midwest, including those on the fall line, a geomorphologic feature in the southeastern U.S. marking the final rapids on rivers before the ocean. Historically, waterborne transport of goods required portage around the falls at these...

Many researchers have used time series models to construct population forecasts and prediction intervals at the national level, but few have evaluated the accuracy of their forecasts or the out-of-sample validity of their prediction intervals. Fewer still have developed models for subnational...
