For a long time, we have believed that strong corporate governance is enough to prevent CEO malfeasance. However, new research shows that the lifestyle behaviors of executives can spell trouble for companies, regardless of the guardrails in place. Aiyesha Dey, an associate professor at Harvard Business School, has investigated executives’ past criminal records and the cost of their homes and automobiles. Her research has linked an individual’s materialism and propensity for rule breaking to fraud, insider trading, and risky business activities. She says that boards and other hiring bodies should pay more attention to personal behavior when picking organizational leaders. Dey wrote the HBR article "When Hiring CEOs, Focus on Character."
