Air pollution, weather, and agricultural worker productivity
利用两个大型农场6年的收割工人工资记录与多源污染和天气监测数据，研究发现地面臭氧和PM2.5浓度升高会降低农业工人生产力，分别导致生产力下降2%和1.1%。
Abstract Outdoor agricultural workers often work in harsh environmental conditions, including high temperatures and poor air quality. This paper studies how these factors impact worker productivity, which can have implications for worker health, well‐being, and income as well as farm payroll, production, and profitability. Our analysis uses 6 years of payroll records of harvesters on two large farms combined with pollution and weather monitor data from multiple sources. We address simultaneity issues by exploring pollution measurements from nearby upwind and downwind monitors and incorporating an alternative PM 2.5 measure that better captures ambient or regional concentration. Across all specifications, results suggest that heightened concentrations of ground‐level ozone and PM 2.5 are associated with reduced productivity. In our main specification, we find that one standard deviation increases in ozone and PM 2.5 are associated with reductions in productivity of 2% and 1.1%, respectively.
