The U.S. labor market experienced a more than 20 percent reduction in the share of workers holding multiple jobs over the past 20 years. While this substantial trend is receiving increasing attention, the literature lacks a comprehensive picture of the gross worker flows that underlie the...

We extend Nakamura et al. (2019, 2020)'s approach of using the publicly available microdata files of the Labour Force Survey (LFS) to construct worker transition rates across employment, unemployment, and inactivity. Our approach involves estimating and applying a scaling factor that has been...

We use a set of empirical and analytical tools to conduct parallel analyses of involuntary part-time work and unemployment in the U.S. labor market. In the empirical analysis, we document that the similar cyclical behavior of involuntary part-time work and unemployment masks major differences in...

We document that fluctuations in part-time employment play a major role in movements in hours per worker, especially during cyclical swings in the labor market. Building on this result, we propose a novel representation of the intensive margin based on a stock-flow framework. The evolution of...

In this paper, we examine how skill loss can contribute to aggregate labor market fluctuations in the Diamond-Mortensen-Pissarides model. We develop a computationally tractable stochastic version of that model wherein workers accumulate skills on the job and face a risk of skill loss after job...

A search-theoretic model of the labor market with idiosyncratic fluctuations in hours worked, search both off- and on-the-job, and multiple jobholding is developed. Taking on a second job entails a commitment to hold onto the primary employer, enabling the worker to use the primary job as her...
