ABSTRACT Past studies have documented an ex‐dividend day price drop which is less than the dividend per share and positively correlated with the corresponding dividend yield. In contrast to prior work, we show that, without additional information, the marginal tax rates cannot be inferred from this phenomenon which is, therefore, not necessarily the result of a tax induced clientele effect. Despite adjustments for potential biases in earlier work, however, the correlation between the ex‐dividend relative price drop and the dividend yield is still positive which is consistent with a tax effect and a tax induced clientele effect.

This empirical study of security issues by UK companies between 1959 and 1974 focuses on how companies select between financing instruments at a given point in time. It throws light on a number of interesting questions. First, it demonstrates that companies are heavily influenced by market conditions and the past history of security prices in choosing between debt and equity. Second, it provides evidence that companies appear to make their choice of financing instrument as if they have target levels of debt in mind. Finally, the results are consistent with the notion that these target debt levels are themselves a function of company size, bankruptcy risk, and asset composition.

ABSTRACT This paper presents a theory of the demand for investment banking advising and distribution services for the case in which the investment banker is better informed about the capital market than is the issuer, and the issuer cannot observe the distribution effort expended by the banker. The optimal contract under which the offer price decision is delegated to the better‐informed banker in order to deal with the adverse selection and moral hazard problems resulting from the informational asymmetry and the observability problem is characterized. The model demonstrates a positive demand for investment banking advising and distribution services and provides an explanation of the underpricing of new issues.
