The Effect of Pollution and Heat on the Productivity of High-Skill Public Sector Workers in China

Matthew E. Kahn, Pei Li, May 22, 2019

The quality of governance depends on public sector worker productivity. We use micro data from China to document that judges are less productive on polluted days.
