我们估计了温度对认知能力的影响，发现一年中超过29摄氏度的10天会使数学和阅读考试成绩分别降低0.03和0.02个标准差。然而，与以前的工作相比，我们发现证据的收入机制炎热的日子在生长季节减少农业产量和测试成绩的表现与相对温和的影响炎热的日子在非生长季节。有条件现金转移支付计划的推出，为穷人提供了一个安全网，削弱了温度和考试成绩之间的联系。我们的研究结果表明，气候变化将对农业经济中贫困人口的人力资本积累产生不成比例的巨大负面影响，可能会增加贫困的持续性。JEL代码：H41，I0，Q5，Q54
We present estimates of the effect of temperature on cognitive performance, and find that an additional 10 days in a year above 29C reduces math and reading test scores by 0.03 and 0.02 standard deviations respectively. However, in contrast to prior work, we find evidence for an income mechanism hot days during the growing season reduce agricultural yields and test score performance with comparatively modest effects of hot days in the non-growing season. The roll-out of a conditional cash transfer program, by providing a safety net for the poor, weakens the link between temperature and test scores. Our results suggest that climate change will have disproportionate and large negative impacts on human capital accumulation of poor populations in agrarian economies, likely increasing the persistence of poverty.
