Abstract
We use a field experiment to estimate the marginal value of non-work time (MVT). During the application process to staff a national call center and data entry positions we randomly offer applicants alternative hour and wage packages. Applicant choices over these packages yield estimates for the MVT for this population of jobseekers as a function of hours worked. They also allow us to estimate a labor supply function.

Experimental Design
Experimental Design
Applicants to data entry and phone survey positions are asked which of two positions they would prefer. One is H hours per week at X dollars per hour, and one is H+5 hours per week at Y dollars per hour, where H varies from 5 to 35 in 5-hour increments. Both jobs are explicitly one-month, work-from-home positions. Both the choice of hours and the wages are randomized. To determine individuals’ value of time above 40 hours per week, we ask randomly-selected individuals to choose between either (1) a 40 and 45 hour per week job or (2) a 45 and 50 hour job. In both cases, we randomize the wage paid for overtime hours.

In addition to the experiment, we add a module to the nationally-representative Understanding America Study that asks individuals hypothetical questions about their preference between two jobs with different hours per week and wages.
