Comparing Efficiency Across Markets: An Extension and Critique of the Zhang and Bartels (1998) Methodology

The use of non-parametric frontier methods for the evaluation of product market efficiency in heterogeneous markets seems to have gained some popularity recently. However, the statistical properties of these frontier estimators have been largely ignored. The main point is that nonparametric frontier estimators are biased and that the degree of bias depends on specific sample properties, most importantly sample size and number of dimensions of the model. To investigate the effect of this bias on comparing market efficiency, this contribution estimates the efficiency for several datasets for two main product categories. Following Zhang and Bartels (1998), these results comprise re-estimates for the larger samples limiting their size to that of the smaller samples when the model dimensions for different samples are identical. Furthermore, sample sizes are adjusted to mitigate the eventual differences in dimensions in specification. This allows comparing market efficiency for different markets on a more equal footing, since it reduces the bias effect to a minimum making the comparison of market efficiency possible. However, the article also points out the critical limitations of this Zhang and Bartels (1998) approach in certain respects. Apart from reporting these negative results, we also offer some suggestions for future work.Market Efficiency, Heterogeneous Product Markets, Bias, Monte-Carlo Simulation

How Does the Retail Environment Influence Shoppers? Emotional Experience? Evidence from Two Retail Settings

This study examines the relationships that exist among shoppers? perceptions of a retail environment and their emotions, satisfaction, and behavioural intentions with respect to that shopping setting. A model of these relationships is developed and then tested in two distinct retail settings?shopping centres and traditional retailing areas. The results show that, in general, positive perceptions of a retail environment have a positive influence on positive emotions, on repatronage intentions, and on desire to remain longer in the shopping area in both retail settings. However, some interesting differences emerge between shopping centres and traditional retailing areas: (i) there is a stronger effect of internal environment on emotions in shopping centres than in traditional retailing areas; and (ii) there is a negative effect of internal environment in shopping centres on disposition to pay more

The impact of service/product performance and problem-solving on relationship satisfaction

International audiencePurpose The purpose of this paper is to merge service and product quality concepts as well as problem-solving capabilities and relationship satisfaction into an integrative model and empirically test it in business-to-business (B2B) context. Design/methodology/approach Hypothesis testing was performed using a structural equation model based on a LISREL approach applied to a sample of 1,218 industrial buying centers producing and marketing food and beverage products for industrial use in Belgium, France and Holland. Findings The model allows a comparison between the relative efficacy of product quality, service and sales quality as well as problem-solving in driving relationship satisfaction. The results demonstrate the relative effectiveness of sales team quality while also emphasizing the importance of problem-solving in building relationship satisfaction. Originality/value This study makes theoretical and empirical contributions providing a better understanding of the impact of service/product quality and problem-solving in building relationship satisfaction in a B2B context

La qualité perçue comme déterminant de la satisfaction des clients en business-to-business: une étude empirique dans le domaine de la téléphonie

La mesure de la qualité perçue et de la satisfaction des clients occupe une place importante dans la stratégie des entreprises ainsi que dans la littérature académique. L'objet de cet article est de tester les relations qui existent entre la qualité perçue et la satisfaction des clients industriels d'un fournisseur de centraux téléphoniques en ayant recours à plusieurs informants par firme cliente. L'analyse des données — collectées pendant quatre ans — illustre : (1) la multidimensionnalité du concept de qualité perçue; (2) l'influence positive des dimensions de la qualité perçue sur la satisfaction des clients et (3) le rôle de la qualité du produit en tant que médiateur partiel de la relation entre la qualité de service et la satisfaction

Le marketing scientifique à l’usage des managers : 1. L’étude de la relation client

L’Étude de la Relation Client est un enjeu majeur au sein de toutes les entreprises. Tout professionnel se voit assigner des objectifs de conquête de nouveaux clients, d’augmentation du taux de fidélité ou encore de préservation du capital client. Autant de mots qui sont sans valeur s’ils ne sont pas accompagnés d’outils d’évaluation et de pilotage. Et dans ce cadre-là, la réalité est souvent déconcertante. Les outils à disposition des professionnels sont non seulement peu nombreux mais souvent inappropriés ou révèlent rapidement des limites en termes d’apprentissages et de leviers d’actions. Parallèlement, la littérature scientifique regorge de débats et d’études comparatives sectorielles actualisant la pertinence des instruments de mesure en termes de validité ou de fiabilité. Plus précisément, l’étude de la relation client fait émerger des mesures calibrées au niveau de la qualité perçue, de la satisfaction, de la confiance, de l’engagement et de la fidélité. L’ambition de cet ouvrage est de créer une passerelle entre le monde scientifique et le monde opérationnel. Fournir aux scientifiques un accès aux enjeux opérationnels d’aujourd’hui et de demain. Fournir aux professionnels un accès vulgarisé et exhaustif aux modalités de mesure des concepts clés de la relation client : qualité perçue, satisfaction, confiance, engagement et fidélité
