Risking public health by approving some health claims? – The case of phosphorus

There is a well-established consensus on the many biological functions of essential nutrients, and related general function health claims will be soon authorised in the European Union. Such claims about the role of nutrients in the body’s growth, development and functioning could provide a powerful marketing tool and significant increase in the consumption of specific food products. Even though these claims are scientifically substantiated, there are both health and ethical concerns about whether such claims should be allowed where the intake of these nutrients easily exceeds the recommendations and a bigger intake might have adverse affects. The case of phosphorus and its role in the maintenance of normal bone is discussed.     

A model of cost-based transfer pricing

In most decentralized organizations, goods and services are transferred between divisions. These transfers are frequently recorded in the accounting books of the divisions; the term transfer price refers to the dollar amount of the interdivisional exchange. This study considers two main issues: (i) the costs and the benefits of delegating decisions through a system of transfer pricing and divisional performance evaluation, and (ii) the performance of one common method of pricing intrafirm transactions: cost-based transfer pricing.The study analyzes a firm in which each divisional manager has better information about the divisional environment than what is known by the firm's top management. The first half of the paper demonstrates that the firm can attain the optimal level of profits with a compensation system utilizing (i) reports by divisional managers describing in complete detail each manager's private information, and (ii) divisional performance evaluation with cost-based transfer pricing. Next, a situation is considered in which divisional managers are not able to communicate their private information to the firm's top management because of complexity of divisional environments or managers' specialized expertise. In this bounded-rationality setting, a managerial-compensation system employing cost-based transfer pricing allows the firm to earn strictly higher expected profits than if all decisions are made by the firm's top management relying on divisional managers' reports.Financial support from the Unisys Corporation is gratefully acknowledged.     

The road not taken: competition and the R&D portfolio

This article examines the effects of market structure on the variety of research projects undertaken and the amount of duplication of research. A characterization of the equilibrium market portfolio of R&D projects and the socially optimal portfolio is provided. It is shown that a merger decreases the variety of developed projects and decreases the amount of duplication of research. An increase in the intensity of competition among firms leads to an increase in the variety of developed projects and a decrease in the amount of duplication of research.

Statement of editorial policy

Systematic strategic management is a recent and still developing concern of both practitioners and students of management. It is necessary, therefore, to define in this first issue of the Strategic Management Journal (SMJ) both the limits and the contents of the subject which will be welcomed to its pages. Since we hope to attract our readers and contributors from both practice and academia, it is appropriate to describe strategic management from their respective viewpoints.     

Computing the endogenous mortgage rate without iterations

A number of mortgage prepayment models require a specification of the mortgage rate process. Usually, ad-hoc models are used (e.g., a Treasury yield plus some constant). Recently, a number of papers have appeared where the authors have utilized a mortgage rate implied by the current yield curve (the so-called endogenous mortgage rate). However, the existing computational algorithms suffer from the curse of dimensionality and, consequently, are problematic to use for full-scale problems. A computational algorithm, proposed in this paper, is tractable in the sense that its complexity is equivalent to the problem of mortgage valuation. Moreover, the algorithm does not require iterations. The numerical example is based on a PDE computation. An implementation of a Monte Carlo method is also discussed.     

Estimation of the most influential science and technology factors for economic growth forecasting by soft computing technique

Economic growth may be developed on the basis on combination of different factors. In this investigation was analyzed the economic growth forecasting based on the different factors. The main goal was to analyze the influence of science and technology factors on the economic growth. Gross domestic product (GDP) was used as economic growth indicator. The method of adaptive neuro fuzzy inference system (ANFIS) was applied to the data in order to select the most influential factors for the GDP growth rate forecasting. Ten inputs are considered: research and development (R&D) expenditure in GDP, scientific and technical journal articles, patent applications for nonresidents, patent applications for residents, trademark applications for nonresidents, trademark applications for residents, total trademark applications, researchers in R&D, technicians in R&D and high-technology exports. The ANFIS process for variable selection was also implemented in order to detect the predominant factors affecting the forecasting of GDP growth rate.
