    This paper examines the causal effects of retirement on health investment behavior among Japanese permanent employees. We find that the Japanese employees participate less in unhealthy habits (smoking and drinking) after retiring from their permanent employment, and after completely ceasing to work, they further increase participation in healthy life habits (regular exercise). We also find gender differences in these responses. (C) 2017 Elsevier B.V. All rights reserved.

    About 10% of primary school students in developing countries have poor vision, but very few of them wear glasses. Almost no research examines the impact of poor vision on school performance, and simple OLS estimates could be biased because studying harder may adversely affects one's vision. This paper presents results from a randomized trial in Western China that offered free eyeglasses to rural primary school students. Our preferred estimates, which exclude township pairs for which students in the control township were mistakenly provided eyeglasses, indicate that wearing eyeglasses for one academic year increased the average test scores of students with poor vision by 0.16 to 0.22 standard deviations, equivalent to 0.3 to 0.5 additional years of schooling. These estimates are averages across the two counties where the intervention was conducted. We also find that the benefits are greater for under-performing students. A simple cost-benefit analysis suggests very high economic returns to wearing eyeglasses, raising the question of why such investments are not made by most families. We find that girls are more likely to refuse free eyeglasses, and that parental lack of awareness of vision problems, mothers' education, and economic factors (expenditures per capita and price) significantly affect whether children wear eyeglasses in the absence of the intervention.

    We examine the role of information in understanding the differential effects of income on the demand for health. In the health capital framework of Grossman (JPE, 1972), we derive the testable hypotheses that individuals adjust their diet in a healthier direction upon receiving negative health information, and that the effect is greater for richer individuals. Based on unique Chinese longitudinal data and a regression discontinuity design that exploits the exogenous cutoff of systolic blood pressure in the diagnosis of hypertension, we find that, upon receiving hypertension diagnosis, individuals reduce fat intake significantly, and richer individuals reduce more. Our results also indicate that among the rich, hypertension diagnosis is more effective for individuals with lower education. (C) 2012 Elsevier B.V. All rights reserved.

    Youth smoking can biologically reduce learning productivity. It can also reduce youths' expected returns to education and lower their motivation to go to school, where smoking is forbidden. Using rich household survey data from rural China, this study investigates the effect of youth smoking on educational outcomes. Youth smoking is clearly an endogenous variable; to obtain consistent estimates of its impact, we use counts of registered alcohol vendors and a food price index as instrumental variables. Since the variable that measures smoking behavior is censored for non-smoking adolescents, we implement a two-step estimation strategy to account for the censored nature of this endogenous regressor. The estimates indicate that smoking one cigarette per day during adolescence can lower students' scores on mathematics tests by about 0.08 standard deviations. However, we find no significant effect of youth smoking on either Chinese test scores or total years of schooling. (C) 2012 Elsevier B.V. All rights reserved.
