Designing research to reveal the young child's emerging competence

The focus of this paper is to suggest factors which a marketing researcher should consider in designing experimental procedures that are congruent with the young child's cognitive capacities. Several components of the experimental environment are identified as important in designing an age-appropriate task: familiarity with factual information, context, verbally presented information, and the goal of the experimental task. A young child's strategies for processing an experimental task that exceeds his or her cognitive capacities are considered. Finally, the paper addresses implications for marketing researchers when tailoring experimental procedures to young children.     

Purchasing professionals in state government: How ethical are they?

A survey of purchasing professionals in the Arizona state government was conducted to determine how familiar the buyers were with the Arizona laws regarding ethical conduct, what ethical standards they followed in purchasing, and what types of ethical dilemmas they faced in their work. The findings indicate that no serious ethical problems exist among the respondents. Employees in the centralized purchasing office seemed to act somewhat more ethically than buyers in peripheral offices, however. Laura B. Forker is a doctoral candidate in the Department of Purchasing, Transportation, and Operations at Arizona State University. She has published in the Journal of Purchasing and Materials Management and Comparative Economic Studies.     

Autocorrelation and masked heterogeneity in panel data models estimated by maximum likelihood

In a panel data model with random effects, when autocorrelation in the error is considered, (Gaussian) maximum likelihood estimation produces a dramatically large number of corner solutions: the variance of the random effect appears (incorrectly) to be zero, and a larger autocorrelation is (incorrectly) assigned to the idiosyncratic component. Thus heterogeneity could (incorrectly) be lost in applications to panel data with customarily available time dimension, even in a correctly specified model. The problem occurs in linear as well as nonlinear models. This article aims at pointing out how serious this problem can be (largely neglected by the panel data literature). A set of Monte Carlo experiments is conducted to highlight its relevance, and we explain this unpleasant effect showing that, along a direction, the expected log-likelihood is nearly flat.     

Investigating the limits of competitive intelligence gathering: is mystery shopping ethical?

In this article we take further the debate on the ethics of competitive intelligence gathering, which until now has been very limited. Drawing on empirical research from a mobile telephone company in the United Kingdom, we present the case that while mystery shopping is not the worst activity in which an organization might be involved, it is basically unethical. Mystery shopping involves deception and the obtaining of competitive information under false pretences. Common arguments are that 'everyone is doing it' and that the information is in the public domain. Neither of these points convincingly justifies the requirement for an employer to ask an employee to lie and deceive others on behalf of the company. The use of students and those in low power positions in the organization is a further concern.     

On Effective Interdisciplinary Alliances in European Business Ethics Research: Discussion and Illustration

Cooperation in business ethics research is important across disciplines, to help strengthen the base of a field which is still new in Europe. A study on recruitment interviewing in Germany, U.K. and the Netherlands is used to demonstrate the value of interdisciplinary business ethics research, particularly across cultures.
