An econometric time‐series model of off‐board trading of NYSE‐listed stocks shows that high NYSE commission rates were an incentive for third‐market trading but that trading on the regional exchanges, which is most of the off‐board trading, has been affected very little by commissions or their deregulation. The effects of some changes in the trading organization and rules are estimated, including several that are part of the emerging National Market System. The estimates imply that the NMS has increased competition for the NYSE, as Congress intended, and has prompted the NYSE to improve its performance to retain market share.

Previous research suggests that firms choose negotiated issuance over competitive despite its apparently higher net interest cost. This result is shown to arise partly from failure to correct for a selectivity bias in the choice of issuance procedures. Two stage analysis is used in a model that includes qualitative and limited dependent variables to re‐estimate the net interest cost difference between competitive and negotiated issues. Results support the hypothesis that the choice of issuance procedure is consistent with shareholder wealth maximization. Examination of debt issues subject to Rule 50 of the Public Utility Holding Company Act indicates that the regulation, as applied, is not effective.

We examine the impact of capital income taxation, both accrual forms of taxation and taxation of realized capital gains, on total savings and the demand for corporate financial instruments. We find that investors may hold both debt and equity in the face of effective collection of capital gains taxation even in a flat tax system. We also find that the two taxes will have substantially different effects on saving and consumption behavior, making it unlikely that the tax structure can be summarized by any single equivalent accrual tax rate.

The purpose of this paper is to empirically test the relationships between corporate earnings and investment. In particular, the study investigates whether knowledge of past investments improves the prediction of future earnings beyond predictions that are based on past earnings alone. Similarly, it investigates whether knowledge of past earnings improves the prediction of future investments beyond knowledge of past investments alone. This is the empirical definition of Granger causality. The empirical results show that the bivariate past series of earnings and investments is superior to the univariate series in predicting future investments but not in predicting future earnings.
