Bad apples or corrupting barrels? Preventing traders’ misconduct

Abstract

Purpose This paper aims to identify social psychological root causes of misconduct by traders and offers practical guidelines to prevent misconduct. Design/methodology/approach The authors use insights on social psychological mechanisms to examine current business practices observed in the context of supervisory activities. Case examples were collected at Dutch and European banks, including major institutions. This is an opinion peace that interprets regulator experiences from a social psychological perspective. Findings The authors characterize standard responses to misconduct in trading as reactive and elucidate why this “bad apples” perspective is insufficiently effective. As an alternative, the authors address the social psychological root causes of misconduct within trading teams. The “corrupting barrels” model identifies ineffective error approaches, outcome inequality and dysfunctional moral climates as contextual root causes in team dynamics. The model uses current insights from empirical research in psychology to do so. Practical implications This paper specifies practical guidelines that help prevent future misconduct among traders. Originality/value Addressing the contextual root causes of misconduct at the team level will help banks and financial supervisors to improve their effectiveness in preventing misconduct. In the context of standard “bad apples” approaches, the “corrupting barrels” model offers an original perspective.
