The casual observer of accounting and business management is often surprised to learn that significant questions about the way in which accounting is used in decision-making remain unanswered. Yet, not until recent years has attention been focused on the seemingly important relationships among accounting, accounting systems, and the kinds of decisions which business managers make.' While the results of empirical studies undertaken to date are almost all tentative rather than conclusive, few can read them without appreciating the significance for accounting of the questions which have been considered. There are reasons to believe that the future development of accounting depends upon identifying relationships among accounting, decisions, organizational structure, and operations of accounting and information systems. The research which provides the basis for this paper was initiated to seek the answer to a simple question. Is the frequency with which accounting information is reported to management an important determinant of the decisions which managers make? A simple laboratory experiment using a business game was designed. The laboratory environment allowed participants to be divided into two groups. The first group received financial statements and other data each period, while making
Inventory calculation procedures may be viewed as a set of linear transformations or functions which map the appropriate price and quantity vectors into a corresponding set of valuation scalars. This paper examines some of these calculations in terms of elementary matrix operations. The matrix can be readily adapted to the computer, and standard programs now exist for performing matrix algebra operations. These can be used for the required accounting calculations discussed herein. First, we consider purchase transactions; each such transaction may be described by a pair of points representing quantity and unit price, respectively. The purchase quantities, by years, may be represented by a diagonal matrix having, as the elements of its main diagonal, the quantities purchased during each accounting period. Such a matrix, Q, with typical element qji, for n accounting periods would appear as follows:
