Research into "How Widespread and Predictable is Stock Broker Misconduct?" by SLCG indicates that prior customer complaints against individual brokers can indicate future complaints. McCann, Qin, and Yan discovered that including co-worker complaint histories significantly improves the ability to predict complaints against brokers who have not been previously complained about. They also found that customer complaints that were denied - not only settlements and awards - are useful in predicting future investor harm.
Egan, Matvos and Seru's results confirm that, rather than weeding bad brokers out of the industry, the regulatory environment and labor market sifts bad brokers down the quality ladder over time into brokerage firms who employ brokers with disproportionately higher numbers of customer complaints. These high-risk brokerage firms have loose hiring practices and lax compliance ethics and specialize in preying on unsophisticated 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.
