Exploring the role of social proximity in bank lending using a proprietary data set, we uncover evidence of a significant social proximity effect on private information acquisition. Local loan officers have better information to identify higher-quality borrowers through improved screening. This advantage is greater when firms have higher information asymmetry and lower ratings. Results suggest that sociocultural resources drive locals’ informational advantages and improve their lending performance. Importantly, we find that the social proximity advantage interacts with loan officer incentives. Strong evidence suggests that loan officers can be incentivized to use their social proximity advantage to make better loans.

We hypothesize that cognitive limitation may be manifested in a disproportionately large volume of limit orders submitted at round-number prices if investors use these numbers as cognitive shortcuts. Using detailed limit order data in the Taiwan Futures Exchange, we find that investors with lower cognitive abilities, defined as higher limit order submission ratios at round numbers, suffer greater losses in their round-numbered and non-round-numbered limit orders, market orders, and round-trip trades. The positive correlation between cognitive ability and investment performance is monotonic and robust across futures and options markets. In addition, past trading experience helps mitigate cognitive limitation.
