Yields on short-term prime-grade municipals vary through time in relation to after-corporate-tax yields on short-term U.S. Treasury securities. The pattern is not related to the default premium in municipal yields or to the historical ceiling on bank deposit rates (Regulation Q). However, there is a strong link to the default premium in corporate yields and to municipal holdings by large commercial banks. These findings suggest that taxable and tax-exempt markets are linked both by the capital-structure decisions of firms and by the tax-arbitrage activities of banks.

This paper examines the robustness of one month treasury bills as predictors of inflation. The evidence is inconsistent with the joint hypothesis that (1) the expected real rate of interest was constant for one-month bills and (2) that markets are efficient with regard to the time series of inflation. When the expected real rate of interest is set equal to the conditional expectation given the time series of real rates, the results are much more consistent with the efficient markets model. In more positive terms, the failure to confirm market efficiency appears to be the result of naive estimates of the expected real rate.

[We account for the relation between stock returns and inflation with two independent disturbances: supply shocks and demand shocks. Supply shocks reflect real output shocks and cause a negative relation between stock returns and inflation, while demand shocks are mainly due to monetary shocks and generate a positive relation between stock returns and inflation. We show, both theoretically and empirically, that the stock return-inflation relation varies over time and across countries, depending on the relative importance of the two types of shocks. Our empirical evidence is based on pre- and postwar periods in the United States, as well as the postwar period in the United Kingdom, Japan, and Germany.]

We investigate stock market rationality by examining the timeliness and unbiasedness of the market's response to dividend announcements. Our initial findings for market timeliness show a sluggish market reaction to dividend announcements; however, when the ex-dividend effect is controlled for, we find no evidence of a sluggish market reaction. We examine the unbiasedness of the market's response by testing whether the net announcement effect across a sample that is devoid of ex-post selection bias sums to zero. We observe a significant positive net announcement effect and examine several plausible conjectures for this puzzling phenomenon, but none provides a satisfactory explanation.

In this paper we examine the ex-dividend day returns of several taxable and non-taxable distributions. The ex-dividend day returns for the taxable common stocks are consistent with the hypothesis that dividends are taxed more heavily than capital gains. However, the ex-dividend day returns of preferred stocks suggest that preferred dividends are taxed at a lower rate than capital gains; non-taxable stock dividends and splits are priced on ex-dividend days as if they are fully taxable; and non-taxable cash distributions are priced as if investors receive a tax rebate with them. We also find that each of these distributions exhibits abnormal return behavior for several days surrounding the ex-dividend day. We investigate several possible explanations for this anomaly, but none is capable of explaining the phenomenon.
