Knowledge that Transforms

Most businesses sell on credit. To administer credit, such companies set credit granting, term, and collection policies. This article analyzes one aspect of credit granting policy: the determination of the optimal number of credit applicants that should be accepted by a creditor. The emphasis in the relevant literature traditionally has been on techniques for estimating a credit applicant's probability of default and, to a lesser degree, on the decision to accept an applicant given his estimated probability of default. Cumulatively, these two decisions are crucial to any business selling on credit.

In a recent article in this Journal, Jacob B. Michaelson and Robert C. Goshay (hereafter M-G) argue that the rule of maximizing share values does not adequately explain the portfolio selection practices of financial intermediaries. Moreover, M-G suggest that their analysis “has ramifications that reach far beyond financial intermediaries.” In particular, they state that “the asset holdings of conglomerate firms and the rationale for mergers may not be fully explicable in terms of maximizing behavior.”

Broadly speaking there are two models to the problem of asset valuation under uncertainty and aversion to risk. Under one, the certaintyequivalent method, each future return is converted to its certainty equivalent and discounted at the pure rate of interest. Under the other, the risk-adjusted discount rate method, each future return is discounted at an appropriate discount rate. The interrelation and validity of these models of asset valuation have come under discussion in two important works on stock valuation.

A theoretical model capable of supporting a rigorous analysis of portfolio selection in financial intermediaries appeared only recently. In the absence of a suitable theoretical framework, the limitations of maximizing behavior as an explanation of the selection of asset and liability structures in this class of firms were obscured. Discussions bearing on this question usually focused on the structure of one or the other side of intermediary balance sheets and gave little attention to the effects of these structures on the risk associated with their equity.

This paper examines the determinants of underwriters' spreads on tax exempt bond issues. In particular, it investigates the effect on spreads of differences in issue quality, term to maturity, and size. In addition, changing money market conditions and variations in the degree of competition among underwriters of tax exempts are analyzed for their influence on spread behavior. The relationships are studied for virtually all state bond issues sold between July 1, 1959 and December 31, 1965. The principal method of investigation is multiple regression analysis.
