Air pollution and the productivity of high‐skill labor: evidence from court hearings*
研究了空气污染对墨西哥司法工作者认知生产率的影响，发现颗粒物每增加10单位，听证会时长增加6.7%，相当于2015-2017年间样本法院损失约56个工作日。
Abstract The influence of air pollution on cognitive productivity is a highly relevant and not fully understood economic issue. This study provides evidence of an adverse effect of exposure on the productivity of Mexican judicial workers. The empirical strategy approximates productivity with the length of the hearing and infers causality through instrumental variable panel models. Results show that air pollution decreases the productivity of judicial workers. For instance, increasing particulate matter by 10 units raises the length of hearings by 6.7 percent. Back‐of‐the‐envelope calculations suggest that if particulate matter had been ten units lower, the sample of courthouses would have gained 81,712 minutes or roughly 56 work‐days between 2015 and 2017.
