Exact excerpt

The study examined the causal impact of air pollution on the academic publications of individual scholars in China. It used an instrumental-variable design combining air-quality data with a bibliographic publication dataset; publication records came from Clarivate Web of Science, air-pollution data from the China National Environmental Monitoring Center, and meteorological data from the Copernicus Climate Data Store. The reported exposure is annual PM2.5 concentration, and the outcome is scholarly publication output.
