The Bartik instrument is formed by interacting local industry shares and national industry growth rates. We show that the typical use of a Bartik instrument assumes a pooled exposure research design, where the shares measure differential exposure to common shocks, and identification is based on...

The Bartik instrument is formed by interacting local industry shares and national industry growth rates. We show that the Bartik instrument is numerically equivalent to using local industry shares as instruments in a GMM estimator and discuss how different asymptotics imply different identifying...

The authors extend methodologies from their previous research to provide estimates of the long-run trend rate of labor force participation (LFP) based on data before the Great Recession (before 2008). Their models suggest that the actual LFP rate as of the third quarter of 2014 is 0.2 to 1.2...

The authors examine the recent decline in teen work activity, offering explanations for both the long secular decline since the late 1970s and the recent acceleration in this decline since 2000. They argue that much of this pattern is due to a significant increase in the rewards to formal...

The degree to which retirement decisions are driven by health is a key concern for both academics and policymakers. In this paper we survey the economic literature on the health-retirement link in developed countries. We describe the mechanisms through which health affects labor supply and...

The degree to which retirement decisions are driven by health is a key concern for both academics and policy makers. In this review, we survey the economic literature on the health–retirement link in developed countries. We describe the mechanisms through which health affects labor supply and...
