Charlene Marie Kalenkoski and Sabrina Wulff Pabilonia (2009) "Time to Work or Time to Play: The Effect of Student Employment on Homework, Housework, Screen Time, and Sleep"
Recent research suggests that working while in high school reduces the amount of time students spend doing homework. However, an additional hour of work leads to a reduction in homework by much less than one hour, suggesting a reduction in other activities. This paper uses data from the 2003-2007 American Time Use Surveys (ATUS) to investigate the effects of market work on the time students spend on homework, sleeping, household work, and screen time. Results show that an increase in paid work reduces time spent in all of these activities by 84 percent, with the largest effect found for screen time.
