Air Quality and the Productivity of High-Skilled Workers: Evidence from GitHub (joint with Felix Holub)
We study how air pollution affects productivity and work patterns among highly skilled tech workers. Using data on GitHub activities, we measure daily output and task choices for a sample of 26,000 software developers across 42 countries during the period 2014-2019. Pairing this with data on daily fine particulate matter (PM2.5) concentration, we show that air pollution has negative effects on the number of total actions performed on GitHub per day. This effect if driven by a reduction in the number of submitted code changes, while activity in interactive tasks (e.g. number of comments in discussion fora) is unaffected. Exposure to unusually high levels of PM2.5 reduces the value of daily output by approximately $11.5 per developer. Developers respond to a deterioration in air
quality by working on easier tasks on high pollution days, and by working more on weekends following workweeks with higher pollution levels to make up for the pollution-induced productivity decline
