We examine how the Affordable Care Act's dependent coverage mandate (DCM) affected young adults' time allocation. Exploiting more accurate measures from the American Time Use Surveys, we find that the DCM reduced labor supply. The question then arises, what have these adults done with the extra time? Estimates suggest a reduction in job‐lock, as well as in the duration of the average doctor's visit, including time spent waiting and receiving care. The latter effect is consistent with substitution from emergency‐department utilization toward more routine care. Estimates suggest that the extra time has gone into socializing, and into educational and job‐search activities. (JEL I1, J2, H0)
