Time preference affects individuals' time-allocation decisions such as working and investments in human capital over a lifetime. It also influences individuals' choice of non-market activities on a daily basis. Individuals with higher time preference would spend more time on the non-market activities that provide rather instant gratification such as watching television and eating, whereas those with lower time preference would spend more time on the non-market activities that provide long-term returns such as exercising and taking classes. Using matched data from the Tobacco Use Supplements to the February, June and November 2003 Current Population Surveys and the 2003, 2004 American Time Use Surveys, this paper examines how the differences in time preference, measured by smoking, affect time spent on various non-market activities in an 24-hour period. Even after controlling for a host of variables, I find that current smokers, compared to never smokers, spend more time watching television and eating and drinking but less time exercising and taking classes.JEL Classification: J2, I1
