We examine the effects of the world's first comply-or-explain dividend regulation in China's Shanghai Stock Exchange, which requires firms to either pay at least 30% of profits as dividends or explain the use of funds. We find that many firms increased their payout ratio to comply, by increasing dividends or decreasing earnings. Firms with high profitability, state ownership, and fewer agency conflicts were more likely to comply. However, complying firms subsequently issued more debt and had a decline in accounting performance and firm valuation. The evidence suggests that the comply-or-explain regulation increased firms' dividends at substantial costs.

Recent studies investigate the impact of air pollution on labor productivity. We extend this literature by showing that air pollution negatively affects equity analyst information production. Analysts exposed to air pollution are less likely to issue timely forecasts or improve their forecast accuracy. Investigating the underlying mechanism, we find that analysts exposed to air pollution are less likely to provide bold (especially, negatively bold) forecasts. We also find evidence that market pricing is less sensitive to 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-in-differences designs and placebo tests.
