Abstract

This paper attempted to measure the causal effect of high school quality on academic achievement by estimating education production function in Japan. The authors combined school quality measures retrieved from official statistics with the large sample of twins collected through the web-based survey. This combined dataset enabled us to overcome selection bias and control for unobserved family and genetic characteristics of an individual. The results drawn from the empirical result suggest that school quality at the high school level are not associated with student achievements, but are associated with earnings measured in later life. Therefore, our answer to the specific causal question, does school quality matter in Japan, is “no” for academic achievements, but “yes” for labor market outcomes. The results also show that unobserved family components may play a crucial role in determining academic achievements.
