Knowledge that Transforms

The purpose of this paper is to examine the intertemporal relationship between variations in the prices of individual common stocks and variations in the rest of the stock market. Empirical data are analyzed to determine the frequency with which stock prices precede, occur simultaneously, and follow movements in the market average.

The content of the basic course in finance is analyzed in terms of a number of dimensions. My presentation will focus on six areas: (1) our clients and their needs, (2) the managerial orientation, (3) coverage, (4) role of specialized techniques, (5) application to other purposive organizations, and (6) social responsibility issues.

The dramatic surge of the commodity option market over the past few years may well be illustrated by the growth (before its collapse) of one leading option writer, Goldstein, Samuelson, Inc., whose sales rose from $1 million in 1971 to over $45 million by the end of 1972. The commodity option market is closely related to the commodity futures market, except that options are available only on the so-called “international” commodities.

Financial or capital market theory is intimately concerned with the concept of a general equilibrium. But most of the empirical work in finance has been concerned with the estimation of single-equation ordinary least squares cross-sectional models. One way of capturing some of the flavor of a general equilibrium is to use a simultaneous equation valuation model. Thus the value or the return on a security can be determined simultaneously in relationship to and in competition with the other securities in the system. Simkowitz and Jones [4] have recently described how the methodology could be used. Simkowitz and Logue [5] have recently performed a study using this methodology.

Models developed to explain variations in cash balances of firms have generally postulated forms of rational choice for the decision maker. Two examples of these kinds of models are (1) Baumol's inventory-type model where the choice of the initial balance is made in terms of a planning period in which outflows of cash, but no inflows, are considered; (2) Miller and Orr's model wherein inflows and outflows occur randomly and a decision is triggered to increase or reduce cash balances when an upper or lower threshold is passed. Statistical tests of the inventory-type model have had limited success, particularly in attempts to identify the increasing efficiency in the use of cash balances as a function of the size of the firm. The apparent linear double logarithmic relationship between cash balances of firms and their sales volumes has cast doubt upon the increased efficiency proposition that derives from the Baumol model. Meltzer has modified this model to demonstrate that it implies linearity. The Meltzer tests will be challenged in this paper, and we shall establish that his results, as well as Baumol's conclusions, are particular outcomes that can be better explained in another type of model.

This paper by Hughes, Logue, and Sweeney offers an excellent summary of recent theoretical work on the advantages of multinational firms in providing opportunities for international diversification. In addition, some interesting empirical tests of an international version of the capital asset pricing model (IAPM) are reported. Neither of these topics is original as several writers have explored the theoretical advantages of the multinational firm providing international diversification, including this discussant [1]. The IAPM has been tested by Solnik [2] and others who find that systematic risk is lower in international financial markets than in domestic ones.

The structure and analytical representation of investors' utility-of-wealth functions has long been of interest in portfolio theory. In proposing convenient analytical utility functions most economists have used (i) constant elasticity (power) functions, (ii) the negative exponential function. Both (i) and (ii), of course, restrict the preference structure; Moreover, one may object to (i) because such functions are not uniformly bounded on [0, ∞). And, as has been shown by Arrow [1], this is undesirable in an axiomatic system. The negative exponential function has no such disadvantage, but objections may be raised on empirical grounds. Thus, no simple convenient specification of bounded utility functions on [a, ∞) is available. In fact, even polynomials in wealth of arbitrary order are restrictive since they immediately impose the requirement that moments of wealth are finite. (If the polynomial is of order n, then the nth moment must be finite.)

In the evaluation of investment opportunities risk is often a primary consideration. Risk is usually not a factor of such importance, however, in the evaluation of borrowing opportunities. But when the borrowing opportunities include the borrowing of foreign currencies, then the possibility of exchange rate fluctuations during the loan period may introduce a significant component of risk. It is our purpose to develop a method for evaluating and selecting international borrowing sources in the face of exchange rate uncertainties.
