We examine the timing of firms' operations in a formal model of labor demand. Merging a variety of data sets from Portugal from 1995-2004, we describe temporal patterns of firms' demand for labor and estimate production-functions and relative labor-demand equations. The results demonstrate the...

What explains how much people work? Going back in time, a main fact to address is the steady reduction in hours worked. The long-run data, for the U.S. as well as for other countries, show a striking pattern whereby hours worked fall steadily by a little below a half of a percent per year,...

We investigate the effect of the COVID-19 pandemic on labor activity using real-time data from millions of GitHub users around the world. We show that the pandemic triggered a sharp pattern of labor reallocation at both the global and regional level. Users were more likely to work on weekends...

A transformation of what had become a universal 40 hour standard work week in Germany began in 1985 with reductions negotiated in the metal-working and printing sectors. These reductions have continued through 1995, and were followed by reductions in other sectors. The union campaign aimed to...

Using Current Population Survey data, I demonstrate a 15-percentage point wage disadvantage among academics compared to all other doctorate-holders with the same demographics. Time-diary data show that academics' work hours are distributed more evenly over the week and day, although their total...

We examine patterns of work in the U.S. from 1973-2018 with the novel focus on days per week, using intermittent CPS samples and one ATUS sample. Among full-time workers the incidence of four-day work tripled during this period, with over 8 million more full-time workers on four-day weeks. The...

Comparing measures of work time in the recall CPS-ASEC data with contemporaneous measures reveals many logical inconsistencies and probable errors. About 8 percent of ASEC respondents report weeks worked last year that contradict their current work histories in the Basic monthly interviews; the...

This paper uses a revealed preference approach applied to administrative data from Washington to document and characterize work-hour constraints. Workers have limited discretion over hours at a given employer, and there is substantial mismatch between workers who prefer long hours and employers...

The COVID-19 pandemic instigated a big shift in working arrangements. I first describe the scale of this shift in the United States, drawing on the Survey of Working Arrangements and Attitudes and other sources. I then review differences, circa 2023, in work-from-home rates across industries,...

We expand the analysis of cyclical changes in labor demand by decomposing changes along the intensive margin into those in days/week and in hours/day. Using large cross sections of U.S. data, 1985-2018, we observe around 1/4 of the adjustment in weekly hours occurring through changing days/week....
