Applying financial portfolio and multiple criteria approaches to product line decisions

This article describes the application of decision rules from financial portfolio theory to the evaluation of product lines. The focus is on the risk/return implications of an “add” decision to the total portfolio versus the individual product. Multiple criteria approaches that aid product line evaluations are also presented.

Interest and reaction time analysis of credit card offers: Managerial implications of high level research procedures

This paper presents a new approach to the optimisation of direct mail offers. Conjoint measurement will be used to identify two aspects of an offer: the degree of interest; and the speed at which an individual processes the information. The approach allows the marketer to create offers that are simultaneously attractive to customers and easy to understand. The approach is illustrated by a credit card case study.     

Comparing spatial concentration and assessing relative market structure in air traffic

Traffic distributions of air traffic and their concentration have been measured through Gini, an index that contrasts in many ways with other more established ones, such as Herfindahl's. This research is extended in the sense that it perceives spatial concentration in air transport as an aggregate of complex networks that are subject to multiple constraints, such as geopolitics or technology. We propose a multi-layered analytic approach where network operators are economic agents that behave in strategic ways. It allows for comparing air traffic between airports in Europe with that of the US and, in particular, introduces a normative component by isolating patterns in airlines' strategies that coincide with more or less welfare-oriented degrees of spatial concentration in light of the above constraints.     

How Africa can benefit from knowledge

Africa's poverty partly stems from the lack of strong scientific, technological and knowledge bases. The abundance of natural resources on the continent has been of limited value to the African people because they do not have the tools with which to turn their resources into consumable wealth. To rectify this situation, African policy makers would have to undertake various measures. First, they need to define the type of knowledge their countries require. Second, they ought to establish conditions for nurturing strategic leaders who will, in turn, seek the right forms of knowledge to tackle Africa's problems. Third, policy makers need to build the political and legal frameworks that encourage the absorption and application of scientific innovations. Fourth, African leaders ought to revamp the universities, establish regional research centres, and take capacity building more seriously. It is these measures that will facilitate Africa's meaningful participation in global knowledge flows. Above all, knowledge creation should aim at attaining human welfare, participatory democracy, peace building and socio-economic justice.     

Work experiences,work adjustment and psychological well-being of expatriate employees in Hong Kong

This study replicated and extended research on expatriate work adjustment by examining the antecedents of work adjustment and its outcomes in terms of psychological well-being. Data were obtained from a nationally heterogeneous sample (N = 184) of expatriate employees in Hong Kong using a structured questionnaire. Results of regression analysis revealed role conflict to be significantly negatively related to work adjustment, while role discretion, co-worker support and work-method ambiguity (clarity) were significantly positively related to work adjustment. Of the three hypothesized outcomes, work adjustment was significantly positively related only to job satisfaction but not to quality of life and marital adjustment. Though not the focus of this study, interaction adjustment was found to be significantly positively related to quality of life. Limitations of the study and implications of the findings are discussed.
