We develop and implement a protocol to measure U.S. monthly time series of involuntary part-time employment stocks and flows from 1976 until today. Armed with these new data, we provide a comprehensive account of the cyclical dynamics of involuntary part-time work. We find that the recessionary...

Although the size of the labor force is nearly acyclical, worker flows between employment and unemployment on the one hand and inactivity on the other hand fluctuate significantly over the business cycle. After reviewing these facts, this paper lays out a job-search model to uncover the...

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...

In this paper, we first provide a comprehensive account of the relationship between cross-country differences in aggregate employment and disaggregated differences in worker flows along the life cycle. To this end, we use survey micro-data for 31 European countries, and estimate the life-cycle...

We develop an adjustment procedure to construct U.S. monthly time series of involuntary part-time employment stocks and flows from 1976 until today. Armed with these new data, we provide a comprehensive account of the dynamics of involuntary part-time work. Transitions from full-time to...

The number of workers who hold more than one job (a.k.a. multiple jobholders) has increased spectacularly in Canada since the mid-1970s – it has been multiplied by almost three. In this paper, we document this historical change and provide a comprehensive account of its dynamics. To this end,...

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...
