In recent years considerable attention has been paid by marketing theorists to the role of advertising and other promotional activities within the marketing policy of the firm and to their optimal setting in the combined operation of the various instruments available to such a policy. These...

In a recent article in Management Science, F. P. Adler [Adler, F. P. 1960. Relationships between organization size and efficiency. Management Sci. 7 (1, October) 80-84.] developed a simple model to analyze the implications of a growing research organization and the resulting increase of internal...

The order of discussion is as follows. In Section 2 the basic ideas (which are already "classical") are briefly restated and the problem is formulated. In Section 3 some proposals are made for the weights of the linear combination of individual preference functions. Section 4 illustrates the...

The procedure of "adaptive" or "exponential" forecasting is based on weighted averages of two sources of evidence; one is the latest evidence (the most recent observation), the other the value computed one period before. As such, it is an easy, quick and cheap method; very little information is...

The article describes a procedure to maximize a strictly concave quadratic function subject to linear constraints in the form of inequalities. First the unconstrained maximum is considered; when certain constraints are violated, maximization takes place subject to each of these in equational...

In a recent article L. G. Telser [Telser, L. G. 1963. Least-squares estimates of transition probabilities. Measurement in Economics: Studies in Mathematical Economics and Econometrics in Memory of Yehuda Grunfeld, Chapter 11, Stanford University Press, Stanford, California.] considered the...

Balance sheets and income statements are numerical decompositions of certain total sums: total assets, total liabilities, total sales, and total costs and expenses. The behavior of individual items measured as fractions of the corresponding total is important for the analysis of the company's...

Von Neumann and Morgenstern formulated the expected-utiiity approach in terms of a simultaneous utility-probability axiomatization, which makes utility unique up to a linear transformation. This note illustrates, that there are situations in which it is convenient to consider utility or, more...

It is shown that the proposal for a utility-weighted informational measure discussed by Belis, and Guiasu (Belis, M., S. Guiasu. 1968. A quantitative-qualitative measure of information in cybernetic systems. IEEE Trans. Information Theory 14 593--594.) and others can be formulated in terms of...

The impact of price changes in geometric programming is analyzed in terms of technological substitution relationships. The method can also be applied to sensitivity analysis, which is illustrated by means of a numerical example.
