Private Benefits of Control, Ownership, and the Cross‐listing Decision

Journal of Finance 2009 64(1), 425-466 open access
This paper investigates how a foreign firm's decision to cross‐list on a U.S. stock exchange is related to the consumption of private benefits of control by its controlling shareholders. Theory has proposed that when private benefits are high, controlling shareholders are less likely to choose to cross‐list in the United States because of constraints on the consumption of private benefits resulting from such listings. Using several proxies for private benefits related to the control and cash flow ownership rights of controlling shareholders, we find support for this hypothesis with a sample of more than 4,000 firms from 31 countries.

Are Analyst Short‐Term Trade Ideas Valuable?

Journal of Finance 2022 77(3), 1829-1875
Short‐term trade ideas are a component of analyst research highly valued by institutional investors. Using a novel and comprehensive database, we find that trade ideas have a stock price impact at least as large as recommendation and target price changes. Trade ideas based on expectations of future events are more informative than those identifying incomplete incorporation of past information in stock prices. Analysts with better access to a firm's management produce better trade ideas. Institutional investors trade in the direction of trade ideas. Investors following trade ideas can earn significant abnormal returns, consistent with analysts possessing valuable short‐term stock‐picking skills.

Risk management, firm reputation, and the impact of successful cyberattacks on target firms

Journal of Financial Economics 2021 139(3), 719-749 open access
We develop a model where a firm has an optimal exposure to cyber risk. With rational, fully informed agents and with no hysteresis, a successful cyberattack should have no impact on a financially unconstrained target's reputation and post-attack policies. In contrast, when a successful attack involves the loss of personal financial information, there is a significant shareholder wealth loss, which is much larger than the attack's out-of-pocket costs. This excess loss is higher when the attack decreases sales growth more and lower when the board pays more attention to risk management before the attack. Further, an attack decreases a firm's risk appetite, as it beefs up its risk management and information technology and decreases the risk-taking incentives of management. Finally, successful cyberattacks adversely affect the stock price of firms in the target's industry. These results imply that successful attacks with personal financial information loss provide adverse information about cyber risk to target firms, their stakeholders, and their competitors.
