The effect of hyperchoice on the consumer and the moderating effect of the brand: an application in the jewelry market

The objective of this research is to study the reactions of consumers when faced with a hyperchoice situation. Two experiments were carried out, varying the number of products displayed in a jewelry department. The results show that increasing the number of products has a positive effect on the perception of price and the sensation of choice, but a negative effect on the attractiveness of the showcase, the perception of quality, the perception of product originality, and the desire to make a choice. However, these effects of hyperchoice are largely attenuated by the presence of a brand.

“The taste of others” : divergences in tastes between professional experts and ordinary consumers of movies in France

The omnipresence of professional experts in the debates and marketing strategies around movies raises the question of the proximity of their judgments with those of the “ordinary consumer”. Two theoretical perspectives compete on this matter: Divergence or convergence of tastes. Based on a sample of 622 popular films released between 2005 and 2009 in France, this research confirms the divergence of tastes: Professional experts grant no special value to movies that ordinary consumers prefer. However, our results also suggest that publication on the Internet of “hybrid” tastes (those of web users and media critics) builds an artificial form of convergence which can be useful for the markets actors.

L’effet de « révélation asymétrique » : Influence de l’augmentation du nombre de photos sur l’imagerie mentale et les réponses comportementales selon le niveau de gamme

Les recherches qui étudient l’effet du nombre de photos sont rares et ne concernent que des expérimentations manipulant un nombre réduit de photos non informationnelles. Cet article propose une première étude menée en terrain réel sur 3658 petites annonces immobilières et montre que l’augmentation du nombre de photos diminue les réponses comportementales favorables si le bien est de gamme inferieure, mais reste sans effets si le bien est de gamme supérieure. Ce résultat est répliqué et expliqué dans une étude expérimentale : pour un bien de gamme inférieure, l’ajout de photos dégrade la valence des images mentales, l’imagerie mentale de soi et augmente l’inquiétude perçue. Ces variables expliquent l’effet négatif du nombre de photos sur les réponses comportementales. En revanche, pour un bien de gamme supérieure, l’ajout de photos – informationnelles ou non – n’améliore pas les réponses comportementales. Cet effet de « révélation asymétrique » selon le niveau de gamme des biens est discuté.

‘Asymmetric revelation’ effect: The influence of an increased number of photos on mental imagery and behavioural responses depending on target market

There has been little research exploring the effect of the number of photographs used to present a product, and the studies that have been carried out relate to experiments with a reduced number of non-informative photos. This article provides a first field study conducted on 3,658 real estate ads and shows that an increase in the number of photos decreases favourable behavioural responses for lower range properties, but has no effect in the case of higher range properties. This result is replicated and explained in an experimental study: for lower range properties, the addition of photos deteriorates the valence of mental images, decreases mental self-imagery and increases perceived worry. These variables explain the negative effect of the number of photos on behavioural responses. However, for higher range properties, the addition of photos – informative or not – does not improve behavioural responses. This ‘asymmetric revelation’ effect depending on the segment of the property market being targeted is discussed.
