PaperA uniform profit margin policy and its effects on mineral producing firms The case of the oil industry

AbstractThe current paper highlights the lack of any framework for the analysis of the effects of current methods of rate of return regulation on the target firms and proposes an alternative method based on the market cost of the capital invested in a regulated firm. Using a framework developed from an earlier model, the effects of a uniform profit margin (UPM) on the efficiencies of oil firms are examined. The results show that the effects depend on the type of firm and on whether the UPM is below or above the firm's capital expansion rate (CER). Essentially, UPM will make the most efficient firms (MEFs) operate at a lower or higher efficiency level depending on whether they are below or above their CER; make accelerated cost firms (ACFs) more inefficient in terms of higher supernormal profits at the expense of society; and make accelerated production firms (APFs) more efficient, provided there are no restrictions on the firms' choice of method of adjusting production rates. In general, the approach encourages firms that have less than desirable investment levels to raise the level, and discourages excessive investment for the sole aim of reaping higher profits.

A framework for empirically investigating the power of functional units in organizations

AbstractContemporary views of power and the state-of-the art of research in organizational power are grossly inadequate for evolving an index for determining the power of functional units. The current paper introduces two important elements of power: time and organizational power — mission link — (leading to two related concepts of power: static and dynamic views of power). On the basis of that, a framework for measuring the power held by functional units is proposed. By case study approach, the application of the methodology is demonstrated. The results, among other things, show that every functional unit has some degree of power, which varies with time, in response to the dynamics of the relevant environment; some management implications are highlighted.

Theory and MethodologyAn algorithm for systems welfare interactive goal programming modelling

AbstractEvery human system is faced with the problem of choosing between alternative options, and methods of interactive programming have been suggested as the best way to lead decision makers reach decisions that are consistent with their preferences. However, even though a large number of interactive algorithms have been proposed for multiobjective decision making (MODM), there is yet no truly interactive goal programming (GP) algorithm, despite the preference of GP over other MODM methodologies. The current paper presents an algorithm for interactive GP modelling called SWIGP (systems welfare interactive GP) which ensures that the overall welfare of the system under consideration is adequately taken into account in the interactive process. To achieve this, this paper distinguishes between technical, allocative and economic efficiencies and combines an economic efficiency index with interactive GP process. Besides being of wide applicability, the algorithm exerts little cognitive burden on the decision maker (DM). Indeed, even if the DM is assumed to operate under conditions of complete ignorance, SWIGP provides the direction for searching the “best” compromise solution. Moreover, the algorithm converges very fast because of the economic efficiency index that complements the interactive process in aiding the DM arrive at a most preferred solution.
