Air Pollution and Adult Cognition: Evidence from Brain Training
利用大脑训练游戏的数据，研究发现PM2.5暴露损害成人认知功能，对劳动年龄人群影响最大，且对新任务和低能力者更显著，加剧了生产力不平等。
We exploit novel data from brain-training games to examine the impacts of air pollution on a comprehensive set of cognitive skills in adults. We find that exposure to particulate matter (PM2.5) impairs adult cognitive function and that these effects are largest for those in prime working age. These results confirm a hypothesized mechanism for the impacts of air pollution on workforce productivity. We also find that the cognitive effects are largest for new tasks and for those with low ability, suggesting that air pollution increases inequality in productivity.
