Asset Returns, Discount Rate Changes and Market Efficiency
The primary purpose of this paper is to reconcile the previous findings of discount rate endogeneity with the presence of discount rate announcement effects in securities markets. The crux of this reconciliation is the dictinction between "technicral" discount rate changes that are endogenous and "non-technical" changes which contain some informative policy implications. In essence, we attempt to separate expected discount rate changes from unexpected changes, or equivalently, the expected component of discount rate changes from the unexpected component. If markets are efficient, the former should have no announcement effects while the latter may be associated with an announcement effect. Accordingly, the focus of the empirical analysis is on the interaction between discount rate exogeneity, the specific monetary policy regime, and announcement effects. In addition, we examine whether the behaviorof these markets in the post-announcement period is consistent with the rapid price adjustment implied by market efficiency.
The Effect of Risk on the Firm's Optimal Capital Stock: A Note
In this paper we extend the recent work on the choice of input mix under uncertainty. In particular, we demonstrate that the qualitative nature of the disturbance term, along with the decision sequence, is a crucial determinant of the overall effect of uncertainty on the optimal input mix of a firm. Using general demand and production functions in conjunction with a mean-variance framework for financial valuation, we demonstrate the differential effects of systematic and non-systematic risk on the firm's choice of an optimal input mix. Consistent with earlier work in economics, this analysis demonstrates that uncertainty, regardless of the source, has important implications for the firm's choice of technology.
Taxes, Default Risk, and Yield Spreads
This paper represents an extension and integration of recent empirical and theoretical research on default risk and taxability. The purpose of the paper is to develop and test a model of interest rate spreads which incorporates both the effect of taxes and differences in default probabilities in a theoretically correct manner. There is an important fundamental difference between our approach to explaining yield spreads and the approach most commonly taken in literature. Unlike nearly all of the previous work, we do not begin with a yield spread model, i.e.,one which begins by examining differences in yields, but rather begin with an expected return or pricing model, which can then be expressed in the yield spread format. This is a fundamental difference in approaches which we feel leads to a superior theoretical formulation which can then be tested empirically without many of the problems inherent in the alter-native approach. The theoretical model is a simple extension of earlierwork on default by Bierman and Hass (1975) and Yawitz (1977), altered appropriately to take explicit account of tax effects. While there is a considerable literature that analyzes the effect of taxability on rate spreads, we are unaware of any previous study that considers tax consequences in the event of default, a rather surprising omission.
Interest Rate Risk, Immunization, and Duration
Theoretical and empirical research on fixed-income securities, with special emphasis on maturity selection strategies, has been a major area of investigation during the last several years. In fact, one might argue that in no other area of financial research is the application of theory to practice more rapid not the intersection of interests between academics and practitioners greater. While it is difficult to attribute this heightened interest in fixed-income research to a specific event, there is no doubt that the increased volatility of interest rates and the introduction of innovative financing features have been important factors
Evaluating the Decision to Issue Discount Bonds: Term Structure and Tax Effects
There is considerable evidence that during periods of high interest rates participants in the financial markets rely more heavily on innovative financing methods. In an attempt to deal with the high interest rates of recent years, corporate borrowers have devised a series of special characteristics for corporate bond issues including put options, detachable warrants, and variable coupon rates
