Knowledge that Transforms

In this paper, we examine the stock price reactions to announcements of new security offerings by Real Estate Investment Trusts (REITs). REITs offer a unique setting in which to study these events because they do not pay taxes at the firm level. Theory suggests that the net tax gain to corporate borrowing is unambiguously negative for a REIT. Contrary to some recent studies, however, we find a positive stock price reaction to debt offerings, while the negative equity-issuance effect is preserved. Further empirical evidence lends support to signalling as the explanation for the positive significant debt-issuance effect.

This paper characterizes the complete class of time‐invariant portfolio insurance strategies and derives the corresponding value functions that relate the wealth accumulated under the strategy to the value of the underlying insured portfolio. Time‐invariant strategies are shown to correspond to the long‐run policies for a broad class of portfolio insurance payoff functions.

This paper re-examines the effects of nominal contracts on the relationship between unanticipated inflation and individual stock's rate of return. This study differs in three main ways from previous research. First, announced inflation data are used to examine the effects of unanticipated inflation. Second, a different specification is used to obtain more efficient estimates. Third, additional nominal contracts are considered. The empirical results indicate that time-varying firm characteristics related to inflation predominately determine the effect of unanticipated inflation on a stock's rate of return. A firm's debt-equity ratio appears to be particularly important in determining the response.

This paper shows that the sharp narrowing with maturity of the spread between taxable and tax‐exempt yields leaves room for tax arbitrage. At times, tax‐exempt forward rates have exceeded taxable forward rates. At such times, only expectations of higher taxes on Treasury than on municipal bonds would eliminate profit opportunities. The authors develop the idea of forward tax rates and compute forward tax rates for 1955 through 1984. They also outline tax‐arbitrage mechanisms involving private forward sale of long municipal bonds or the use of the Municipal Bond Futures Contract and show the potential profits.

The APT is represented as a multivariate regression model with across-equations restrictions. Both observed and unobserved (latent) macroeconomic factors are included, thus generalizing and unifying two previous strands of literature. Large portfolios representing unobserved factors are treated as endogenous, and nonlinear 3SLS estimates are shown to differ sharply from estimates that ignore this endogeneity. Using monthly stock returns and six factors, we cannot reject January effects. The following results are invariant with respect to the inclusion of January effects: we reject the CAPM in favor of the APT; however, we cannot reject the APT restrictions on the linear factor model.

This paper introduces an estimator of stock price volatility that eliminates, at least asymptotically, the biases that are caused by the discreteness of observed stock prices. Assuming that the observed stock prices are continuously monitored, an estimator is constructed using the notion of how quickly the price changes rather than how much the price changes. It is shown that this estimator has desirable asymptotic properties, including consistency and asymptotic normality. Also, through a simulation study, the authors show that it outperforms natural estimators for the low‐ and middle‐priced stocks. Furthermoret, he simulation study demonstratest hat the proposed estimator is robust to certain misspecifications in measuring the time between price changes.
