Recent studies investigate the impact of air pollution on labor productivity. We extend this literature by showing that air pollution negatively affects equity analysts in their role as providers of information for capital markets. Compared to analysts experiencing clean air, analysts exposed to particulate matter (PM) pollution are less likely to issue timely forecasts or improve their forecast accuracy. Investigating the mechanism behind this result, we find that air pollution deters analysts from producing information. When analysts are exposed to air pollution, they are less likely to provide bold (especially, negatively bold) forecasts, which is consistent with analysts mapping new information into revised forecasts to a lesser extent. We also find evidence that market pricing is less sensitive to analyst forecast revisions issued by analysts exposed to air pollution. Our results are robust to controlling for firm/analyst and time fixed effects, as well as additional specifications employing difference-indifferences designs and placebo tests.
