Abstract

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 of the U.S. labor market, both in normal times and during recessions. Specifically, we find an upward secular trend in turnover between full-time and part-time employment, and a large cyclical component chiefly explained by fluctuations in involuntary part-time work. We show that these patterns cannot be uncovered without splitting employment into finer categories because both short-run and long-run reallocations along this margin occur mostly without an intervening spell of non-employment. We emphasize the importance of our findings for several active debates, such as the slowdown in U.S. labor-market dynamism, changes in job stability and security, and the assessment of labor-market slack.
