Research

  • Shawn Kim, Wayne Guay, David Tsui (Working), Determinants of Insider Trading Windows.

    Abstract: We use observed insider trades to assess the economic determinants that explain the enforcement of company-imposed quarterly open trading windows. We find that insider trading restrictions reflect concerns about information asymmetry, the strength of external monitoring, and executives’ liquidity needs. We also show that enforced trading windows constrain opportunistic insider trading activity, with insiders generating larger trading profits when boards set trading policies that are abnormally loose. We also identify and explore the enforcement of event-specific “ad hoc blackout windows,” by firms engaged in material corporate events. Interestingly, the absence of trading in these windows is associated with contemporaneously higher information asymmetry. These periods are then followed by increased trading volume and higher stock returns, suggesting investors may not immediately incorporate all information conveyed by unscheduled trading restrictions.

  • Kevin Chen and Wayne Guay (2020), Busy Directors and Shareholder Satisfaction, Journal of Financial and Quantitative Analysis, 55 (7), pp. 2181-2210.

    Abstract: Prior research has examined the firm-level performance implications of “busy” boards. Firm-level analysis, however, masks important heterogeneity in the time constraints and expertise of individual busy directors. We develop and validate shareholder voting as a proxy for shareholders’ satisfaction. Our director-specific tests provide compelling evidence that the potential costs of busy directors outweigh their benefits. At the same time, we uncover new sources of heterogeneity among busy directors. For example, the downsides are more pronounced for directors who sit on boards where fiscal year ends cluster in the same month. Our analysis highlights the role of shareholder voting in board composition research.

  • Kevin Chen, Wayne Guay, Richard A. Lambert, Multidimensional Corporate Governance: Board Independence, Board Expertise, and Equity Incentives.

    Abstract: Corporate governance is a multidimensional construct, with many interactive mechanisms that must be simultaneously managed for efficiency. We develop a model where three ubiquitous governance mechanisms—board independence, board expertise, CEO equity incentives—are endogenously selected to encourage information sharing by the CEO and to optimize the board’s ability to monitor and advise the CEO. We find that, in equilibrium: (i) board expertise and equity incentives are substitutes (complements) when the board has high (low) independence; (ii) boards with greater independence also have higher expertise; and (iii) equity incentives may be positively or negatively related to board independence, depending on the nature of board advice.
