The research conducted by SLCG on "How Widespread and Predictable is Stock Broker Misconduct?" revealed that prior customer complaints against individual brokers can be indicative of future complaints. McCann, Qin, and Yan's findings indicate that including the complaint histories of co-workers significantly improves the ability to predict complaints against brokers who have not previously been complained about. They also concluded that customer complaints that were denied - not just settlements and awards - can effectively forecast future investor harm.
Egan, Matvos, and Seru's findings validate that instead of purging problematic brokers from the industry, the regulatory and labor market dynamics gradually channel these brokers towards firms that hire individuals with a disproportionately high volume of customer complaints. These firms, known for their lax hiring standards and relaxed compliance standards, specialize in exploiting inexperienced investors.
Dimmock et al. [2016] in a related study find that financial fraud is contagious. They find that a broker's propensity to commit financial fraud is significantly influenced by his or her coworkers' propensity to commit fraud after controlling for firm culture, branch atmosphere, market conditions and state regulatory environment.
