The Effect of Pollution on Worker Productivity: Evidence from Call Center Workers in China
We investigate the effect of pollution on worker productivity in the service sector by focusing on two call centers in China. Using precise measures of each worker’s daily output linked to daily measures of pollution and meteorology, we find that higher levels of air pollution decrease worker productivity. These results manifest themselves at levels of pollution commonly found in large cities throughout the developing and developed world. (JEL J2…

Particulate Pollution and the Productivity of Pear Packers
We study the effect of outdoor air pollution on the productivity of indoor workers at a pear-packing factory. Increases in fine particulate matter (PM 2.5 ), a pollutant that readily penetrates indoors, leads to significant decreases in productivity, with effects arising at levels below air quality standards. In contrast, pollutants that do not travel indoors, such as ozone, have little, if any, effect on productivity. This effect of outdoor poll…
