Knowledge that Transforms

This study examines the valuation consequences of control-related outcomes that follow toehold acquisitions. We find evidence that toehold acquisitions facilitate value enhancing control transfers. The types of control transfers not only include takeovers, but also internal mechanisms, such as proxy fights and management turnovers. We find that toehold targets experiencing such control transfers exhibit an abnormal increase in share value, while those not experiencing such control transfers exhibit an abnormal decrease in share value. The results suggest that the positive valuation effect associated with toehold acquisitions reflects the expected benefits of subsequent control transfers.

As demonstrated by Boyce and Kalotay (1979) and Brick and Ravid (1985), the use of long-term debt may be preferred because of tax-related advantages. Brick and Ravid show that if there exists a tax advantage to debt and nonstochastic interest rates, long-term debt will increase the present value of the tax benefits of debt if the term structure of interest rates, adjusted for risk of default, is increasing. A decreasing term structure, on the other hand, calls for short-term debt. The present paper extends the tax-induced argument of Brick and Ravid to allow for the presence of stochastic interest rates. Once interest rates are uncertain, pricing even under risk neutrality becomes a complex issue. We analyze the debt maturity decision under two competing pricing equations: the return to maturity expectations hypothesis and the local expectations hypothesis. (This terminology is used in Cox, Ingersoll, and Ross (1981) and Campbell (1986).) Under uncertainty, a debt capacity factor will create an additional incentive to issue long-term debt. Our other results may be interpreted to indicate that if the term premium, the difference between the implied forward interest rate and the future expected spot rate, is positive (sufficiently negative) then long-term (short-term) debt maturity strategy is optimal.

An algorithm is described that prices European average options. The algorithm is tested against Monte Carlo estimates and is shown to be accurate. The speed of the algorithm is comparable to the Black-Scholes algorithm. A closed-form solution is derived for European geometric average options.

Corporate risk hedging with forward contracts increases value by reducing incentives to underinvest. This occurs because the hedge decreases the sensitivity of senior claim value to incremental investment, allowing equity holders to capture a larger portion of the incremental benefit from new investment. Hedging also allows the firm to credibly commit to meet obligations in states where it otherwise could not, which improves contract terms the firm can negotiate with customers, creditors, and managers. These benefits cannot be duplicated by individual hedging, and each result holds independent of agents' risk preferences.

This paper examines the pricing of exchange rate risk in the U.S. stock market, using two factor and multi-factor arbitrage pricing models. Evidence is presented that the relation between stock returns and the value of the dollar differs systematically across industries. The empirical results, however, do not suggest that exchange risk is priced in the stock market. The unconditional risk premium attached to foreign currency exposure appears to be small and never significant. As a result, active hedging policies by financial managers cannot affect the cost of capital, and other reasons must explain why firms decide to hedge.
