In 1952, the average quarterly volatility of U.S. state employment growth stood at 1.5 percent. By 1995, employment growth volatility came in at just under 0.5 percent. While all states shared in the decline, some states declined much more dramatically than others. We analyze aspects of this...

This paper examines the role local labor markets play in the production of innovations. The authors appeal to a labor market matching model (á la Berliant, Reed, and Wang 2004) to argue that in dense urban areas, workers are more selective in their matches and are therefore more productive....

Many recent studies have identified a decline in the volatility of U.S. real output over the last half century. This study examines a less discussed and analyzed trend, but one as significant as the drop in output volatility, namely a substantial decline in employment volatility during the...

In this paper, the authors document a pronounced trend toward deconcentration of metropolitan employment during the postwar period in the United States. The employment share of initially more dense metro areas declined and those of initially less dense metro areas rose. Motivated by this...

In this study the authors show that during the postwar era, the United States experienced a decline in the share of urban employment accounted for by the relatively dense metropolitan areas and a corresponding rise in the share of relatively less dense ones. This trend, which the authors call...

In this paper, the authors document that the disparity in employment densities across U.S. metropolitan areas has lessened substantially over the postwar period. To account for this deconcentration of metropolitan employment, the authors develop a system-of-cities model in which an increase in...

A key finding to emerge from this study is that the widely studied suburbanization or decentralization of employment and population is only part of the story of postwar urban evolution. Another important part of the story is a postwar trend of relatively faster growth of jobs and people in the...
