Using experimental data, we document that the impact of professional norms on the risk-taking of bank employees depends on their expectations of peers’ risk preferences. When the professional identity of bank employees is made salient, those who expect colleagues to take more risk than themselves increase risky investments by 5.2% points in a mock investment task, while others do not statistically change their risk-taking behaviors. Data from placebo experiments with non-bank employees do not exhibit such empirical patterns. The results are consistent with peer effects and social identity theories, and challenge the existing evidence that professional norms in the banking industry decrease risk-taking.
