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 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...

Multiple jobholding has declined in the United States during the past two decades. Data from the Current Population Survey show that the trend reflects a lower propensity to moonlight among single jobholders. Multiple jobholders on the other hand did not become more likely to return to single...

Are labor markets more turbulent now than thirty years ago? Most job and worker flows imply that the answer is “no”, with one exception: occupational mobility, which increased substantially in the United States. This paper remedies the lack of comparable evidence by focusing on France for...

A search-theoretic model of the labor market with endogenous variations 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 outside...

This paper provides a unified account of the trends in unemployment and labor force participation pertaining to the employment experience of older male workers during the past half-century. We build an equilibrium life-cycle model with labor-market frictions and an operative labor supply margin,...

This paper analyses the optimal design of a single open-ended contract (SOEC) and studies the political economy of moving towards such a SOEC in a labour market where employment protection is highly discontinuous. We develop a computationally tractable approach to compare two economic...

We address methodological breaks in data collection on part-time employment to construct new monthly time series of U.S. stocks and flows spanning the period from 1976 onwards. Using these data, we document that part-time employment plays an increasingly important role in shaping the functioning...

We match cell phone data to administrative school records and combine it with information on school learning modes to study effective in-person learning (EIPL) in the U.S. during the pandemic. We find large differences in EIPL for the 2020-21 school year. Public schools averaged less EIPL than...
