This study develops a currency option pricing model under stochastic interest rates when interest rate parity holds, and it is assumed that domestic and foreign bond prices have local variances that depend only on time. We demonstrate how existing currency option models are simply derived from one framework. Empirical tests employing transactions option data reveal that a particularly simple form of the stochastic rate model is uniformly more accurate than a constant rate model for all boundaries and maturities tested.

This paper describes the application of a convergence acceleration technique to the binomial option pricing model. The resulting model, termed the accelerated binomial option pricing model, also can be viewed as an approximation to the Geske-Johnson model for the value of the American put. The new model is accurate and faster than the conventional binomial model. It is applicable to a wide range of option pricing problems.

We analyze a model in which firms signal their quality by using financial policies to commit to cash outflows. Two financial policies may be used: dividend and debt-service obligations. We find sufficient conditions for the informational equilibrium to entail concommitant use of both dividends and leverage in the cost-minimizing combination of the commitment signal. In this equilibrium, better firms pay higher dividends and are more highly levered than lower quality firms.

The paper examines the relevance of information asymmetry between the managers of the firm and the market for the equity issue process. It uses four proxies for information asymmetry and presents three groups of tests: cross-sectional regressions of the reaction at equity issue announcements, comparisons of information asymmetry before and after the announcements, and analyses of the timing behavior observed during the equity issue process. The results show that information asymmetry is a significant variable for equity issues.

Do bond-issuing firms attempt to choose the call, sinking fund, and term-to-maturity features of bonds to improve shareholder wealth? This paper develops and tests two hypotheses about the determinants of bond features using a conditional logistic model. The model is estimated on a sample of bonds issued between 1982 and 1986. Model estimates show that a bond's call, sinking fund, and term-to-maturity features are statistically related to the issuing firm's retention ratio, ratio of convertible to long-term debt, two-year change in net operating income, and whether the firm is listed on the NYSE and included in the S&P400. These findings support the view that firms financing highquality projects, but facing information asymmetries, choose shorter-term (medium-term) callable bonds with and without the sinking fund feature.

This paper develops a valuation formula for multi-period stochastic cash flows consistent with rational risk-averse investor behavior and equilibrium in securities markets. It shows that the CAPM does not have to be sequentially applied in discounting of the cash flows of multi-period projects, and a single beta can be used to measure the riskiness of an uncertain income stream. Hence, a multi-period project is priced as if it offers a single payment. The formula uses a set of assumptions that is slightly more restrictive than the minimum set Constantinides (1980) uses to produce the multi-period version of the CAPM. This paper also demonstrates that, under certain assumptions, covariances of stochastic cash flows with changes in the term structure may be sufficient measures of the cash flows' riskiness.

This paper presents a model in which managers of firms that are takeover targets use debt-financed share repurchase to bond themselves to reduce perquisite consumption and increase investment in the firm. The resulting value increase makes the firm a less attractive target. The optimal level of share repurchase is the result of a trade-off between the benefit of a reduced probability of takeover and the cost of an increased probability of bankruptcy. Unlike earlier explanations of defensive repurchases, which are based on information signalling or control of voting rights, this explanation is independent of the extent of shareholding by target management.

In this paper, we demonstrate that the conflicting results found in the literature of tests of the unbiased forward rate hypothesis (UFRH) depend upon the econometric specification used as well as differences in the time period of estimation. It is established that the time series properties of spot and forward exchange rate data rule out certain econometric specifications used to test the UFRH. Specifically, we find that both spot and forward exchange rates for the U.K., Germany, Japan, and Canada have unit roots and are cointegrated. We also find that the co-integrating parameter in the regression of realized spot on forward rates for each currency is approximately one, implying that researchers who use this specification to test the UFRH may falsely accept the hypothesis simply because of the specification used in the test. Using an alternative error correction specification, we find that the UFRH is resoundingly rejected for all currencies and that the coefficients in this specification exhibit temporal instability. More importantly, we find that the evolution of the estimated parameters is becoming increasingly inconsistent with the UFRH with the passage of time. We conclude the paper with an investigation into potential causes for the gross violation of the UFRH.

This paper tests for seasonal patterns in corporate bond returns using the Dow Jones Composite Bond Average. Each seasonal pattern documented for equities is investigated. For the period 1963–1986, corporate bond returns exhibit January, turn-of-the-year, and weekof-the-month effects, but no significant day-of-the-week or turn-of-the-month effects. In contrast, for the S&P 500 stock index, the turn-of-the-month and day-of-the-week effects are highly significant, but the week-of-the-month effect is less significant, and the January and turn-of-the-year effects are insignificant. The behavior of an equity index constructed using companies in the bond index is similar to that of the S&P, except the turn-of-the-year effect is significant.
