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...

This paper studies the secular behavior of worker reallocation across occupations in the U.S. labor market. In the empirical analysis, we use microdata to construct consistent time series over a forty-five year period, and document that the fraction of employment reallocated annually across...

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...

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...

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...

We propose a model to evaluate the U.K.’s zero-hours contract (ZHC) – a contract that exempts employers from the requirement to provide any minimum working hours, and allows workers to decline any workload. We find quantitatively mixed welfare effects of ZHCs. On one hand they unlock job...

We propose a model to evaluate the U.K.'s zero-hours contract (ZHC) - a contract that exempts employers from the requirement to provide any minimum working hours, and allows employees to decline any workload. We find quantitatively that ZHCs improve welfare by enabling firms with more volatile...
