Gustavo’s research has provided explanations to several interesting capital market anomalies, such as the closed-end fund discount, the tendency of investors to buy familiar stocks, and the apparent ability of managers to forecast future changes in stock prices and interest rates. His current research focuses on the effects of managerial flexibility on firm value, and on the effects of corporate governance and culture on corporate fraud.
