Single mothers' time preference, smoking, and enriching childcare: Evidence from time diaries

Previous research has shown that time preference affects individuals' market time allocation and own human capital investments. This paper uses data from the Current Population Survey-Tobacco Use Supplements, the American Time Use Survey, and the Panel Study of Income Dynamics-Child Development Supplement to examine how time preference, as measured by smoking behavior, affects mothers' time investments in their children under age 13 and children's future test scores. The results indicate that single mothers who smoke spend significantly less time with their children in educational activities, such as reading and homework, and sharing meals with their children than non-smokers. Their children also have lower reading test scores.
