Sah will study conflicts of interest among advisors or leaders—such as physicians, financial advisors, and workplace managers—and the resulting psychological effects on both the advisors and those they supervise or advise. Using data collected from randomized experiments in the field and in the lab, she will analyze how advisors and advisees understand and react to conflict-of-interest disclosures. She will also study how such disclosures can improve the public’s decision-making, and analyze methods for improving the quality of advice given by advisors who have conflicts of interest.
