- In this study, we model the schooling choice and smoking decision of an individual as a function
of time preference. Using high school graduate cohort data from the Korean Education and
Employment Panel (KEEP) survey 2004-2005, we estimate the effect of smoking during the
senior year of high school on academic achievement in terms of the Korean Scholastic Aptitude
Test (KSAT) score and college attendance. We perform the Two Stage Least Squares (2SLS)
estimation to incorporate the possible endogeneity of smoking status due to unobserved
individual heterogeneity. Further, we conduct three identification tests to confirm the validity of
our choice of instrumental variables for smoking variable. Findings uniformly show that heavy
smoking during the school year is negatively associated with test scores and college attendance.
The usual OLS estimates for the cost of youth smoking in educational outcomes are found
