Opioid addiction and mortality skyrocketed over the past decade. A casual look at the geographic incidence of opioid mortality shows sharply higher mortality rates in the Appalachian region, especially in coal-mining areas. This has led observers to make a link that was characterized by one...

National industrial concentration in the U.S. has risen sharply since the early 1980s, but there remains dispute over whether local geographic concentration has followed a similar trend. Using near population data from the Economic Censuses, we confirm and extend existing evidence on national...

For whom has earnings risk changed, and why? To answer these questions, we develop a filtering method that estimates parameters of an income process and recovers persistent and temporary earnings for every individual at every point in time. Our estimation flexibly allows for first and second...

We present a theory of spatial development. Manufacturing and services firms located in a continuous geographic area choose each period how much to innovate. Firms trade subject to transport costs and technology diffuses spatially across locations. The result is a spatial endogenous growth...

We study the effect of mean-preserving labor reallocation on business cycle outcomes. We develop an empirical methodology using a local area's exposure to industry reallocation based on the area's initial industry composition and employment trends in the rest of the country over a full...

One approach to urban areas emphasizes the existence of certain immutable relationships, such as Zipf's or Gibrat's Law. An alternative view is that urban change reflects individual responses to changing tastes or technologies. This paper examines almost 200 years of regional change in the U.S....

We study the joint process of urbanization and industrialization in the US economy between 1880 and 1940. We show that only a small share of aggregate industrialization is accounted for by the relocation of workers from remote rural areas to industrial hubs like Chicago or New York City....

This paper provides causal evidence of the impact of industrial policy on firms' long-term performance and quantifies industrial policy's long-term welfare effects. Using a natural experiment and unique historical data during the Heavy and Chemical Industry (HCI) Drive in South Korea, we find...

While it is by now well known that the privatization of township- and village-run enterprises (TVREs) has been rapidly and widely taking place in China, it is much less known whether and to what extent privatization has improved resource allocation and productivity. As a first step toward the...
