We ordinarily think of people as honest or dishonest, a broad-brush description which implicitly assumes that honesty is a personal characteristic that generalizes across decision domains. If so, a student who cheats on an exam is also more likely to shoplift or lie to a friend or partner. Does knowing that a corporate manager is opportunistic in one decision domain tell us much about whether the manager will misbehave in some other domain? In other words, are some managers just `bad apples’? 

Recently, in the paper “Opportunism as a Managerial Trait: Predicting Insider Trading Profits and Misconduct” Usman Ali, Portoflio Manager at MIG Capital, and I study these questions by examining whether corporate managers who profit by insider trading in their firms’ stocks engage in other forms of misbehavior as well.
