The problem of allocating a fixed set of time-phased investment allowances among competing investment projects and proposals has received great attention in the literature since Weingartner [11] established a linear/integer programming formulation. Reviews of the literature can be found in Weingartner [12], Hunter [6], Hodges [5], and Bernhard [2].

At any point in time a firm must decide both the level of working capital consistent with its productive assets and how to finance these assets. Academic theorists in business administration have traditionally approached decision making of the firm on a segmented rather than on a global basis and have been satisfied with developing suboptinizing decision rules. Thus there has been concern about managing working capital and concern about choosing the optimum capital structure, but traditionally the two decisions have not been made jointly. And even if they were made jointly, decisions would still remain in the working capital area involving inventories, credit granting, and marketable securities. This paper is an attempt to interrelate working capital and capital structure decisions with working capital used not only as a buffer to avoid ruin but also to affect sales via changing inventory levels and credit policies. The possibility of ruin introduces a discontinuity that precludes perfect elimination of leverage effects via a market.

In their comment on a paper by Porter, Wart, and Ferguson [7], Professors Frankfurter and Phillips [2] have raised two serious objections to “any attempt to compare and contrast SD and EV efficiency criteria on empirical grounds.” Essentially, they have argued that empirical comparisons of SD and EV selection rules are invalid because:

a. The EV portfolio building algorithms are not allowed to operate in such tests, and

b. While the estimators of true E and V are derived from and supported by elementary sampling theory, there exists no comparable sampling theory for the estimation of total probability functions.

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.

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.

Although some scholars argue that the United States government's procurement policies in World War II resulted in greater industrial concentration, this study indicates that such was not the case in the aircraft industry.

This study traces the evolution of several large and powerful trade associations in early twentieth-century Germany and seeks to place them in comparative perspective.

This study analyzes the Brazilian experience as a case study in the role of banking in the early stages of economic growth and development.
