Using Dutch time-diary data from 1975-2005 covering over 10,000 respondents for 7 consecutive days each, we show that individuals' sleep time exhibits both variability and volatility characterized by stationary autoregressive conditional heteroscedasticity: The absolute values of deviations from...

The scholarly impact of academic research matters for academic promotions, influence, relevance to public policy, and others. Focusing on writing style in top-level professional journals, we examine how it changes with age, how stylistic differences and age affect impact, and how style and prior...

We examine work patterns 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, with 8 million additional four-day workers. Similar growth occurred in the Netherlands,...

This study goes beyond the immense literature on the quantity of labor that households supply to examine the timing of their labor/leisure choices. Using two-year panels from the United States in the 1970s it demonstrates that couples prefer to consume leisure simultaneously: Synchronization is...

Routine - maintaining the same schedule from day to day - saves time. It is also boring and inherently undesirable. As such, the amount of routine a person engages in is partly an economic outcome, with variations in routine generated by variations in the price of time, household income and the...

I formulate measures of the effective minimum wage, based on broad definitions of the labor costs that face employers, and use these measures in reestimating some simple equations relating the relative employment of youths and adults to the U.S. minimum wage using aggregate data for 1954-78.I...

Eating requires the food materials that make up meals and also time devoted to buying food, preparing meals and eating them, and cleaning up afterwards. Using time-diary and expenditure data for the U.S. for 1985 and 2003, I examine how income and time prices affect time and goods input into...
