Most economic models consider sleeping as a pre-determined and homogeneous constraint on individuals' time allocation neglecting its potential effects on health and human capital. Several medical studies provide evidence of important associations between sleep deprivation and health outcomes...

Many U.S. high schools start classes before 8:00 A.M., yet research on circadian rhythms suggests that students' biological clocks shift to later in the day as they enter adolescence. Some school districts have moved to later start times for high schools based on the prospect that this would...

This study explores the differential impact of weather on time allocation to physical activity and sleep by children and their parents. We use nationally representative data with time use indicators objectively measured on multiple occasions for more than 1,100 child-parent pairs, coupled with...

The relationship between physical activity and child health and development is well-documented, yet the extant literature provides limited causal insight into the amount of physical activity considered optimal for improving any given health or developmental outcome. This paper exploits exogenous...

Using the 2012-13 American Time Use Survey, I find that both who people spend time with and how they spend it affect their happiness, adjusted for numerous demographic and economic variables. Satisfaction among married individuals increases most with additional time spent with spouse. Among...

We set up a lifecycle model of a retired scholar who chooses optimally the time devoted to different activities including physical activity, continued work and social engagement. While time spent in physical activity increases life expectancy, continued scientific publications increases the...

Using matched data from the Tobacco Use Supplements to the Current Population Surveys and the American Time Use Surveys, this paper examines how differences in time preference, as measured by smoking status, affect time spent on various nonmarket activities in a day. Even after controlling for a...

This paper investigates the channels through which maternal employment affects childhood obesity. We use time diaries and interview responses from the Child Development Supplement of the Panel Study of Income Dynamics which combine information on children's time allocation and mother's labor...
