Knowledge that Transforms

I present evidence consistent with theories that small boards of directors are more effective. Using Tobin's Q as an approximation of market valuation, I find an inverse association between board size and firm value in a sample of 452 large U.S. industrial corporations between 1984 and 1991. The result is robust to numerous controls for company size, industry membership, inside stock ownership, growth opportunities, and alternative corporate governance structures. Companies with small boards also exhibit more favorable values for financial ratios, and provide stronger CEO performance incentives from compensation and the threat of dismissal.

We examine the accounting and market performance of reverse leveraged buyouts (i.e., firms making their first public offering after previously completing a leveraged buyout). On average, the accounting performance of these firms is significantly better than their industries at the time of the initial public offering (IPO) and for at least the following four years, though there is some evidence of a decline in performance. Cross-sectional variation in accounting performance subsequent to the IPO is related to changes in the equity ownership of both operating management and other insiders, and is unrelated to changes in leverage. Finally, there is no evidence of abnormal common stock performance after the reverse leveraged buyout.

This paper presents an equilibrium model of the term structure of interest rates when investors have heterogeneous preferences. The basic model considers a pure exchange economy of two classes of investors with different (but constant) relative risk aversion and gives closed-form solutions to bond prices. I use the model to examine the effect of preference heterogeneity on the behavior of bond yields. The model is also extended to cases of more than two classes of investors.

When commercial banks make loans to firms and also underwrite securities, does this hamper or enhance their role as certifiers of firm value? This paper examines empirically the pricing of bank-underwritten securities as compared to investment-house-underwritten securities over a unique period in the U.S. (pre-Glass-Steagall) when both banks and investment houses were allowed to underwrite securities. The evidence shows that investors were willing to pay higher prices for securities underwritten by banks rather than investment houses. The results support a certification role for banks, which is more valuable for junior and information sensitive securities.

We show that there is a negative relation between leverage and future growth at the firm level and, for diversified firms, at the business segment level. This negative relation between leverage and growth holds for firms with low Tobin's q ratio, but not for high-q firms or firms in high-q industries. Therefore, leverage does not reduce growth for firms known to have good investment opportunities, but is negatively related to growth for firms whose growth opportunities are either not recognized by the capital markets or are not sufficiently valuable to overcome the effects of their debt overhang.

We investigate whether investors price the option to abandon a firm at its exit value. Theory prices this real option as an American put with both a stochastic strike price (exit value) and a stochastic value of the underlying security (the value of cash flows). The empirical implications are that firm value increases in exit value, after controlling for expected going-concern cash flows, and that more generalizable assets produce more abandonment option value. Using discounted earnings forecasts to proxy for expected cash flows and prior literature to categorize asset generalizability, we find strong support for the predictions of abandonment option theory.

We operationalize a firm's competitive strategy through a new empirical measure, and develop a framework for empirical analysis of the market value of strategic behavior. Using this framework, we study announcement effects of R&D spending. The announcing firm's stock prices are positively influenced by a change in spending, and negatively by our competitive strategy measure (CSM). Competitors' stock prices are positively influenced by the interaction between the market's reaction to the announcing firm and the CSM. Our results are consistent with positive effects of ‘accommodating’ competition with strategic substitutes, and nonpositive effects of ‘tough’ competition with strategic complements.

I examine the effect of prudent-man laws on the behavior of institutional investors. Variation in exposure to legal liability across types of investment managers allows me to disentangle the effect of the prudent-man laws from other potential influences on manager behavior. Bank managers significantly tilt the composition of their portfolios toward stocks that are viewed by the courts as prudent, while mutual fund managers choose not. I show that differences in the direction that bank and mutual fund managers choose to tilt may explain their portfolio performance differences over time.

We examine the relationship between U.S. thrift institution ownership structure and risk taking along with the impact of the Financial Institutions Reform, Recovery and Enforcement Act of 1989 (FIRREA) on this relationship. Our results, based on various indicators of risk, suggest that insider controlled thrifts were more likely to engage in risk taking prior to 1989 than were diversely held institutions. FIRREA seems to have curtailed much of this risk taking. We find inverse relationships between risk-taking and levels of institutional shareholdings. This along with other evidence suggests that the motive for risk-taking was not maximization of the ‘option’ value of shares as has been reported elsewhere. We also find evidence that entrenched managers may have generated significant private benefits.

We study the implied volatility behavior of call options around scheduled news announcement days. Implied volatilities increase significantly during the pre-event period and reach a maximum on the eve of the news announcement. After the news release, implied volatility drops sharply and gradually moves back to its long-run level. Only on the event date are movements in the price of the underlying significantly larger than expected. These results confirm the theoretical results of Merton (1973).
