Intervention (Hidden)
This audit study examines gender-differentiated financial advice and commission discounts offered by financial advisors at securities firms in China, aiming to uncover the mechanisms behind these behaviors. To establish causal effects, we employ a randomized controlled trial (RCT) design. Auditors, otherwise identical except for gender, are randomly assigned to 32 distinct investor roles, created by randomizing six characteristics: gender, local status, risk preference, trading frequency, confidence, and planned investment amount. This ensures that the only systematic difference between auditors is their gender, controlling for all other observable characteristics and isolating the causal impact of gender on the financial advice and commission offers received.
This audit study establishes causal effects by using randomization and controlled conditions to isolate the impact of gender on outcomes like financial advice and discounts. Female auditors serve as the treatment group, while male auditors are the control group. The random assignment ensures that any observed differences in financial advice or commission offers are due to gender and not other confounding factors. To further control for external influences, interactions are standardized (e.g., identical scripts, timing, and individual profiles), ensuring that the treatment variable is the only difference between groups. In other words, if male and female auditors with identical profiles receive different commission discounts, the observed difference can be attributed to gender discrimination.
Once assigned, auditors are sent to different branches of securities firms, where they are served by financial advisors who are randomly assigned by the firm. This dual randomization of both auditors and financial advisors ensures that the observed differences can be attributed solely to the treatment variable—gender—allowing us to infer the causal impact of gender on financial advice and commission discounts.
The study is conducted in two rounds: Round 1 during a typical bearish market and Round 2 during a bearish market influenced by a surprising positive policy shock. In both rounds, auditors follow strict protocols for their initial consultations with financial advisors and conduct follow-up meetings within two days to assess any changes in advice or commission offers.
Additionally, a survey of financial advisors is conducted in both rounds to explore the motivations behind their behavior, providing valuable insights into the observed patterns and mechanisms of gender-differentiated financial advice.
