We hypothesize that active mutual funds can promote corporate social responsibility (CSR) in their portfolio firms through stock trading activities. Leveraging mutual fund family mergers to identify causal effects, we find that a firm’s CSR commitment increases when its mutual funds exhibit stronger CSR preferences through trading. This effect is stronger when mutual fund investors are more active or when the firm’s stock exhibits higher liquidity. Additionally, our results suggest that the trading channel complements non-trading mechanisms through which active mutual funds influence firm CSR.

Using China’s religion and household survey data, we find that a high degree of religiosity increases households’ willingness to borrow, both formally from financial institutions and informally from family and friends. A high degree of religiosity could facilitate formal household borrowing by fostering trust in transactions. However, the trust mechanism cannot explain the impact of religiosity on informal borrowing. We hypothesize that a strong religiosity might facilitate informal loans by promoting altruism, and we find supporting evidence. The effect of religiosity on informal loans is more pronounced in transactions where the parties involved are intrinsically less altruistic toward each other.
