Employing the business model concept to support the adoption of product–service systems (PSS)

Although the existing literature indicates that the business model concept can be useful to implement product–service systems (PSS), there is still a paucity of guidelines to assist companies in this respect. Therefore, this paper proposes a framework to support the adoption of PSS employing the business model concept. This framework was developed based on literature review and intends to guide the company on the analysis of their business context, on the choice of the appropriate type of PSS and on the definition of their PSS characteristics. A single case study was then performed to illustrate an application of the framework in a machine tool manufacturer and provide research insights. Overall, results indicate that the framework can provide companies with a useful reference to PSS implementation, helping on the investigation of different PSS scenarios as well as the main barriers and challenges to be overcome.     

Conducting Event Studies on a Small Stock Exchange

Abstract

This paper analyses whether it is possible to perform an event study on a small stock exchange with thinly trade stocks. The main conclusion is that event studies can be performed provided that certain adjustments are made. First, a minimum of 25 events appears necessary to obtain acceptable size and power in statistical tests. Second, trade to trade returns should be used. Third, one should not expect to consistently detect abnormal performance of less than about 1% (or perhaps even 2%), unless the sample contains primarily thickly traded stocks. Fourth, nonparametric tests are generally preferable to parametric tests of abnormal performance. Fifth, researchers should present separate results for thickly and thinly traded stock groups. Finally, when nonnormality, event induced variance, unknown event day, and problems of very thin trading are all considered simultaneously, no one test statistic or type of test statistic dominates the others.     

Barro's fertility equations: the robustness of the role of female education and income

Barro and Lee (1994) and Barro and Sala-i-Martin (1995) find that real per-capita GDP and both male and female education have important effects on fertility in their cross-country empirical studies. In order to assess the robustness of their results, their estimated models are subjected to specification and diagnostic testing, the effects on the model of using the improved Barro and Lee (1996) cross-country data on educational attainment of the population aged 15 and over are examined, and the different specifications used by Barro and Lee and by Barro and Sala-i-Martin compared. The results obtained suggest that their fertility equations do not perform well in terms of diagnostic testing, and are very sensitive to the use of different vintages of the educational attainment proxies and of the Summers-Heston cross-country income data. A robust explanation of fertility, to link with empirical growth equations, has, therefore, not yet been found; further work is required in this area.     

Brand frequency and product involvement: The application of a pc-based perceptual learning routine to psychology and marketing

This article describes a set of procedures that were developed for implementing perceptual learning studies on IBM PCs. The routines permit the display of pictorial and alphanumeric graphic images in 320 × 200 graphics mode, using 4 colors from a 16-color palette. One of the perceptual learning routines—a dot clarification routine—is applied in a study of brand frequency and product involvement as a demonstration of the usefulness of the procedure to issues in psychology and marketing. Perceptual identification was significantly faster for studied items than for nonstudied ones, for high-frequency brands than for low-frequency ones, and for high-involvement products than for low-involvement ones. None of the interactions were significant. We also discuss other potential applications of the perceptual learning procedures to issues in psychology and marketing.     

Corporate governance predictors of adoption of anti-takeover amendments: An empirical analysis

This study of 481 corporations provides an assessment of the relationship between several corporate governance variables (board composition, type of board leadership, officer and director stock holdings, institutional stock holdings, number of majority owners, existence of severance agreements) and adoption of anti-takeover amendments. The results of analysis suggest that the two groups (adopters/non-adopters) differ significantly in regards to these variables.Paula L. Rechner is an Assistant Professor at the University of Houston. She received her Ph.D., her research interests include corporate governance and executive succession/compensation.

Her dissertation examines board governance within the context of antitakeover corporate charter amendments adopted between 1984–1988. Her other research interests include executive succession and corporate social responsibility.Dan R.

American and Canadian perspectives on affirmative action: A response to the Fraser Institute

The publication of the Fraser Institute's Discrimination, Affirmative Action, and Equal Opportunity offers an occasion to review some of the practical and philosophical issues raised by affirmative action policy. Canadian affirmative action programs derive from the American context, which is here reviewed, but do not have the legal recourse available in the American system. Perhaps as a consequence, most Canadian programs have been carried out by governments acting in their role as employers. The Canadian Union of Public Employees has been especially active in developing union perspectives on affirmative action programs, which do raise special concerns for organized labour. Affirmative action raises several basic questions: the importance of proportionality, merit, compensation and role models in determining who is entitled to opportunities in our society. Differences between the Fraser Institute's attitude about affirmative action and attitudes of other social groups, such as the labour movement, lie in their very different assumptions about what constitutes a free society.
