This paper uses a regression discontinuity design to estimate the impact of the minimum legal tobacco purchase age (MLTPA) laws on smoking behavior among young adults. Using data from the confidential version of National Longitudinal Survey of Youth (1997 Cohort), which contains information on the exact birth date of the respondents, we find that the effect of the MLTPA on several indicators of smoking among youth is minor and often insignificant. However, we also show that granting legal access to cigarettes and tobacco products at the MLTPA leads to an increase in several indicators of smoking participation, including up to a 5 percentage point increase in the probability of smoking for males and for those who reported to have smoked before. These results are robust under several alternative model specifications and imply that policies that are designed to restrict youth access to tobacco are quite effective in reducing smoking participation among certain groups of young adults.
This paper uses a regression discontinuity design to estimate the impact of the minimum legal drinking age (MLDA) laws on alcohol consumption and labor market outcomes of young adults. Using confidential data from the National Longitudinal Survey of Youth 1997 Cohort (NLSY97), I find that granting legal access to alcohol at age 21 leads to an increase in several measures of alcohol consumption. The discrete jump in the alcohol consumption at the MLDA has also negative spillover effects on the labor market outcomes of young adults. In particular, I document that the MLDA is associated with a 1 hour decrease in weekly working hours. However, the effect of the MLDA laws on wages is negative only under certain specifications. These results suggest that the policies designed to curb drinking may not only have desirable effects in reducing alcohol consumption among young adults but also have positive spillover effects on their labor market outcomes.
