Knowledge that Transforms

Stocks with relatively high short interest subsequently experience negative abnormal returns, but the effect can be transient and of debatable economic significance. In contrast, relatively heavily traded stocks with low short interest experience both statistically and economically significant positive abnormal returns. These positive returns are often larger (in absolute value) than the negative returns observed for heavily shorted stocks. Thus, the positive information associated with low short interest, which is publicly available, is only slowly incorporated into prices, which raises a broader market efficiency issue. Our results also cast doubt on existing theories of the impact of short sale constraints.

This paper proposes a risk measure, based on first-passage probability, which reflects intra-horizon risk in jump models with finite or infinite jump activity. Our empirical investigation shows, first, that the proposed risk measure consistently exceeds the benchmark value-at-risk (VaR). Second, jump risk tends to amplify intra-horizon risk. Third, we find large variation in our risk measure across jump models, indicative of model risk. Fourth, among the jump models we consider, the finite-moment log-stable model provides the most conservative risk estimates. Fifth, imposing more stringent VaR levels accentuates the impact of intra-horizon risk in jump models. Finally, using an alternative benchmark VaR does not dilute the role of intra-horizon risk. Overall, we contribute by showing that ignoring intra-horizon risk can lead to underestimation of risk exposures.

By reducing the threat of a hostile takeover, business combination (BC) laws weaken corporate governance and increase the opportunity for managerial slack. Consistent with the notion that competition mitigates managerial slack, we find that while firms in non-competitive industries experience a significant drop in operating performance after the laws’ passage, firms in competitive industries experience no significant effect. When we examine which agency problem competition mitigates, we find evidence in support of a “quiet-life” hypothesis. Input costs, wages, and overhead costs all increase after the laws’ passage, and only so in non-competitive industries. Similarly, when we conduct event studies around the dates of the first newspaper reports about the BC laws, we find that while firms in non-competitive industries experience a significant stock price decline, firms in competitive industries experience a small and insignificant stock price impact.

Companies actively seek to appoint outside CEOs to their boards. Consistent with our matching theory of outside CEO board appointments, we show that such appointments have a certification benefit for the appointing firm. CEOs are more likely to join boards of large established firms that are geographically close, pursue similar financial and investment policies, and have comparable governance to their own firms. The first outside CEO director appointment has a higher stock-price reaction than the appointment of another outside director. Except for a decrease in operating performance following the appointment of an interlocked director, CEO directors do not affect the appointing firm's operating performance, decision-making, and CEO compensation.

We model and test the mechanisms through which law affects tunneling and tunneling affects firm valuation. In 2002, Bulgaria adopted legal changes which limit equity tunneling through dilutive equity offerings and freezeouts. Following the changes, minority shareholders participate equally in equity offerings, where before they suffered severe dilution; freezeout offer price ratios quadruple; and Tobin's q rises sharply for firms at high risk of tunneling. The paper shows the importance of legal rules in limiting equity tunneling, the role of equity tunneling risk as a factor in determining equity prices, and substitution by controlling shareholders between different forms of tunneling.

We assess the impact of the Sarbanes-Oxley Act of 2002 on corporate investment in an investment Euler equation framework. We allow a dummy for the passage of the Act to affect the rate at which managers discount future investment payoffs. Using generalized method of moments estimators, we find that the rate U.S. firm managers apply to discount investment projects rises significantly after 2002, while the discount rate for U.K. firms remains unchanged. The effects of the legislation on corporate investment are asymmetric, and are much more significant among relatively small firms. We also find that well-governed firms, firms with a credit rating, and accelerated filers of Section 404 of the Act have become more cautious about investment.

This paper investigates the effects of largest-shareholder ownership concentration, foreign ownership, and audit quality on the amount of firm-specific information incorporated into share prices, as measured by stock price synchronicity, of Chinese-listed firms over the 1996–2003 period. We show that synchronicity is a concave function of ownership by the largest shareholder with its maximum at an approximate 50% level. Further, we find that synchronicity is higher when the largest shareholder is government related. We also find that foreign ownership and auditor quality are inversely associated with synchronicity. Finally, we show that the amount of earnings information reflected in stock returns is lower for firms with high synchronicity.

This paper examines the implications of bank activity and short-term funding strategies for bank risk and return using an international sample of 1,334 banks in 101 countries leading up to the 2008 financial crisis. Expansion into noninterest income-generating activities such as trading increases the rate of return on assets, and it could offer some risk diversification benefits at very low levels. Nondeposit, wholesale funding in contrast lowers the rate of return on assets, while it can offer some risk reduction at commonly observed low levels of nondeposit funding. A sizable proportion of banks, however, attract most of their short-term funding in the form of nondeposits at a cost of enhanced bank fragility. Overall, banking strategies that rely prominently on generating noninterest income or attracting nondeposit funding are very risky, consistent with the demise of the US investment banking sector.

We examine whether and how a US cross-listing mitigates the risk that insiders will turn their firm’s cash holdings into private benefits. We find strong evidence that the value investors attach to excess cash reserves is substantially larger for foreign firms listed on US exchanges and over-the-counter than for their domestic peers. Further, we show that this excess-cash premium stems not only from the strength of US legal rules and disclosure requirements, but also from the greater informal monitoring pressure that accompanies a US listing. Overall, because investors’ valuation of excess cash mirrors how they expect the cash to be used, our analysis shows that a US listing constrains insiders’ inefficient allocation of corporate cash reserves significantly.

We revisit findings that returns are negatively related to financial distress intensity and leverage. These are puzzles under frictionless capital markets assumptions but are consistent with optimizing firms that differ in their exposure to financial distress costs. Firms with high costs choose low leverage to avoid distress, but they retain exposure to the systematic risk of bearing such costs in low states. Empirical results are consistent with this explanation. The return premiums to low leverage and low distress are significant in raw returns, and even stronger in risk-adjusted returns. When in distress, low-leverage firms suffer more than high-leverage firms as measured by a deterioration in accounting operating performance and heightened exposure to systematic risk. The connection between return premiums and distress costs is apparent in subperiod evidence. Both are small or insignificant prior to 1980 and larger and significant thereafter.
