Abstract: Motivated by the significant impacts of environmental risks on economic decisions and the increasing roles of mutual funds in financial markets in recent decades, this study examines the impact of ambient pollution on mutual funds' risk outcomes. Our fund fixed-effect regression estimates use manually collected propriety data from several datasets, showing that polluted air increases tracking errors and mutual fund return volatility. Adopting different identification strategies, including instrumental variable estimations and difference-in-difference analyses based on two natural experiments, suggests that the impact of air pollution on mutual funds' risk is causal. Our findings suggest that air pollution harms fund managers' cognitive abilities and impairs their investment efficiency, thereby increasing mutual funds' tracking errors and return volatility. Overall, our findings provide insights into the impact of climate change on social behavior by shedding new light on the impact of air quality on asset managers' behavior.
