The Cyclical Behavior of Labor Force Participation
We document that labor force participation declines in the short run following a positive technology shock. The countercyclical response of labor force participation to a technology shock contrasts with the well documented mild procyclical behavior of labor force participation in the business cycle. In a search model of the labor market that incorporates a participation choice, we show that a positive technology shock reduces labor force participation in the short run under a reasonable calibration. In the calibrated model, discount factor shocks induce a procyclical response of labor force ...

The Changing Nature of Technology Shocks
We document changes to the pattern of technology shocks and their propagation in post-war U.S. data. Using an agnostic identification procedure, we show that the dominant shock driving total factor productivity (TFP) is akin to a diffusion or news shock and that shock transmission has changed over time. Specifically, the behavior of hours worked is notably different before and after the 1980s. In addition, the importance of technology shocks as a major driver of aggregate fluctuations has increased over time. They play a dominant role in the second subsample, but much less so in the first. We ...
