THE ANALYTICS OF TAX EFFECTS IN DISCOUNT BOND VALUATION

This paper discusses the analytics of tax effects in discount bond valuation. The author illustrates that bond value is a simple linear function of the tax rate on interest income, whereas bond value is concave to the capital gains tax rate. The author also analyzes how changes in tax rates interact with yield changes to affect bond valuation and how tax rates interact with maturity to determine the depth of bond discount.     

THE SEASONALITY IN CONVERTIBLE BOND MARKETS: A STOCK EFFECT OR BOND EFFECT?

There is a strong January effect in convertible bond returns that has been partially attributed to seasonality in the underlying stock. January returns for convertible bonds are positively influenced by the degree to which the bond reflects the underlying equity, which suggests that the anomaly in one asset market may carry over to its derivative asset market. Significant evidence presented here indicates that the January effect also is attributable to unique tax-loss selling in the convertible bond market. A peripheral contribution of this study is that, similar to findings in the stock market, the risk-return trade-off appears to hold only in January for convertible bonds.     

THE NONPARALLEL WEEKEND EFFECT IN THE STOCK AND BOND MARKETS

Explanations for the day-of-the-week effect are either market-specific conventions (timing delays in settlement and clearing, dividend payout arrangements) or cross-market events (bad news delayed until the weekend). Although a market-specific rational is confined to one market, cross-market events affect at least two markets. In this research we investigate the weekend effect in the stock and Treasury markets. Our findings suggest the weekend effect is nonparallel across financial markets. Thus, the weekend effect is more likely due to unique features of the individual markets than to events affecting both stock and Treasury markets simultaneously.     

TRADING TIME EFFECTS IN FINANCIAL AND COMMODITY FUTURES MARKETS

Through the examination of one commodity contract, soybeans, and one financial contract, U.S. Treasury bonds, the authors test to determine (1) whether mean rates of return during trading times differ from mean rates of return during nontrading times; (2) whether mean returns during trading times and nontrading times differ by day of the week; (3) whether trading time returns differ significantly from previous nontrading time returns; and (4) the extent to which trading and previous nontrading returns are correlated. In addition, the authors empirically examine a possible explanation for the results obtained.     

DEBT REFUNDING AND SHAREHOLDER WEALTH: THE PRICE EFFECTS OF DEBT-FOR-DEBT EXCHANGE OFFER ANNOUNCEMENTS

This study examines the impact of debt refunding on common stock prices for a sample of 48 exchange offers announced from 1970 through 1981. Exchange offer announcements do not have a significant impact on average common stock returns but appear to produce idiosyncratic share price effects. Refunding-induced price effects were unrelated to several exchange offer characteristics including tax shield increases, exchange offer premia, and transaction costs of refunding. Common stock excess returns were negatively related to reductions in debt service payments and relaxation of dividend payment constraints. Thus, the evidence is consistent with theories predicting that certain debt refundings generate negative information-signaling price effects.
