In experimental data analysis, marketing researchers are used to discretize the quantitative independent variables to test for their potential moderating effect. From concrete illustrations, this article highlights the limitations of such a practice and aims at presenting the steps of a more...

This article examines the dynamic impact of online word-of-mouth (WOM) on US television show viewership. With WOM data collected from the Internet Movie Database website, we find that the cumulative volume of online WOM has significant explanatory power for viewership over time. Consistent with...

Online consumer reviews (OCR) are conceptualized as a specific form of online word-Of-Mouth, gathering both positive and negative information, numerical (ratings) and textual (comments) information, and which are driven by consumers for consumers on Internet plateforms. In this dissertation, we...

Consequences of network externalities, such as product growth and innovation diffusion, are widely studied in marketing literature. However, there is little empirical research that examines the existence of such network externalities in consumer behavior. When and how do consumers take into...

Labeling a customer as being “brand loyal” is a common marketing practice. Building on the literature on social labeling, marketplace metacognition and skepticism, we investigate the effects of such a practice. We find that skepticism, conceptualized as an expression of marketplace...

The evolution of distribution channels evolves towards a complex multi-channel form, through the increasing importance of the Internet. Along this line, consumer online reviews (COR) platforms rise in order to provide information about the quality of products and services. Despite a growing...

Experimental research scholars often discretize quantitative variables when testing moderation. This pedagogical article addresses the limitations of this approach and considers when and how spotlight and floodlight analyses should be used depending on whether the moderating variable at stake...

Dans l'analyse de données expérimentales, les chercheurs en marketing discrétisent souvent les variables indépendantes de nature quantitative pour tester leur potentiel effet modérateur. A partir d'illustrations concrètes, cet article vise à convaincre des limites d'une telle pratique et...

It is widely believed that increasing the equality of material possessions or income in a social group should lead people at the bottom of the distribution to consume less and save more. However, this prediction and its causal mechanism have never been studied experimentally. Five studies show...

Does asking people about their future behavior increase or decrease the likelihood that they will repeat their past behavior? In two laboratory and two field experiments, we find that behavior prediction strengthens behavior repetition, making people more likely to do what they normally do, when...
