这项研究估计了儿童健康投资的长期影响，利用社区范围内的实验变化，以学校为基础的驱虫。该计划增加了男性的劳动力供应和女性的教育，伴随着劳动力市场专业化的转变。驱虫治疗十年后，符合条件的男孩继续接受小学教育，每周工作时间增加17%，在非农业自营职业中花费更多时间，更有可能从事制造业工作，每周少吃一顿饭。在治疗学校上学的女孩上中学的可能性大约高出四分之一，将性别差距缩小一半。他们将时间从传统农业重新分配到经济作物和非农业自营职业。我们估计，一个保守的年度财务内部回报率为32%的驱虫，并表明，大规模驱虫可能会产生更多的未来政府收入比它的成本补贴。
This study estimates long-run impacts of a child health investment, exploiting community-wide experimental variation in school-based deworming. The program increased labor supply among men and education among women, with accompanying shifts in labor market specialization. Ten years after deworming treatment, men who were eligible as boys stay enrolled for more years of primary school, work 17% more hours each week, spend more time in nonagricultural self-employment, are more likely to hold manufacturing jobs, and miss one fewer meal per week. Women who were in treatment schools as girls are approximately one quarter more likely to have attended secondary school, halving the gender gap. They reallocate time from traditional agriculture into cash crops and nonagricultural self-employment. We estimate a conservative annualized financial internal rate of return to deworming of 32%, and show that mass deworming may generate more in future government revenue than it costs in subsidies.
