We investigate whether air pollution affects household stock market participation. Using representative household survey data in China, we find that households significantly reduce their financial risk taking when exposed to heavy air pollution. This finding is robust to an instrumental variable analysis and a regression discontinuity test based on the Huai River policy. To explore the underlying mechanisms, we find that air pollution significantly impairs health, increases unemployment risk, impedes cognitive performance, and dampens mood. We further show that these channels explain a non-trivial proportion of the relationship between air pollution and stock market participation. Our study sheds light on the far-reaching influence of air pollution on households’ well-being from the perspective of portfolio choice.

This paper investigates whether beauty, an important natural endowment, affects investment decisions. Using data from the Wisconsin Longitudinal Survey (WLS), which provides a photo-based measure of facial beauty, we find that better-looking individuals are more likely to own stocks and invest a larger share of wealth in stocks. We consider a wide range of potential mediators that may drive this relationship between beauty and stock market participation. We find that income and sociability explain a large portion of the beauty effect. For both males and females, beauty has a significant positive impact on stock market participation. Using another dataset that includes the interviewer's rating of the respondent's physical attractiveness, we find similar results. Our study contributes to a better understanding of the economic returns to beauty and the source of heterogeneity in household portfolio choice.
