Why and when is older better? The role of brand heritage and of the product category in the evaluation of brand longevity
No full textInternational audienceDifferent streams in marketing literature report a positive effect from longevity claims (e.g., ‘since 1840’) on perceptions of quality. This paper integrates these different streams under the framework of the existence bias and its corollary, the ‘longer is better’ effect, in order to advance knowledge about this positive bias in consumer decision-making. Four experiments and one survey of a representative sample reveal the following: (1) the ‘longer is better’ effect is non-linear, as increasing the intensity of the claim does not translate into higher perception of quality above a certain point related to the average longevity of the product category; (2) it is mediated by perceived longevity and brand heritage; (3) it is stronger for brands younger than their category’s average longevity, and when consumers believe that there is more competition in the product category. These results have implications for research on the meaning and value of longevity
An Action Design Research to Facilitate the Adoption of Personal Health Records
No full textInternational audienceAdoption and user perceptions are dominant on personal health records literature and have led to a better understanding of what individuals' behaviors and perceptions are about the adoption of personal health records. However, these insights are descriptive and are not actionable to allow creating personal health records that will overcome the adoption problems identified by users. This study uses action design research to provide actionable knowledge regarding user perceptions and adoption and their application in the case of the digital allergy card. To achieve this, we conducted interviews with patients and physicians as part of the evaluation of the digital allergy card mock-up and the first prototype. As results, we provided some research proposals regarding the benefits of, levers for, and barriers to adoption of the digital allergy card that can be tested for several other personal health records

What follows what? Sequences and combinations of acquisitions and divestitures
No full textNational audienceWe review sequential corporate strategy patterns involving divestitures and acquisitions. We classify existing studies into acquisition-preceding-divestiture and divestiture-preceding-acquisition categories to identify four feasible interrelationships linking these two corporate restructuring tools. By acknowledging that acquisitions and divestitures are not definitive steps in resetting a firm’s boundaries, we posit that the value-enhancing mechanisms involved can be observed only if we look at the order of the actions taken. We attempt to understand the multifaceted nature of these sequences and choices to propose an integrated view of acquisitions and divestitures by recognizing the precedents for each restructuring tool. The performance implications of these sequences are not yet known but considering them can better explain the success or failure of strategic restructuring decisions
Is asymmetric cost behavior a pervasive global phenomenon? A meta-analysis of cost stickiness and its main determinants
No full textInternational audienceThis paper addresses the conflicting results arising from the literature on cost stickiness and its determinants. 106 papers were reviewed and several meta-analyses were performed in order to provide more robust results and effect size estimates. The influence of the 4 most researched determinants is also meta-analytically reviewed. Results show that, all types confounded, costs are sticky. The degree of cost stickiness varies across both geographic zones and cost categories although cost of goods sold are non-sticky. Asset intensity increases cost stickiness whereas a successive decline in activity level causes cost stickiness to decrease. Finally, we highlight the remaining gaps and propose several avenues for future research on cost behavior

L’investissement socialement responsable : Changement structurel et faux semblant
No full textInternational audienceSRI is now well established among financial professionals (fund managers or institutional investors), where it has met with widespread success. However, it is struggling to generate the same enthusiasm among the general public, apart from a few individuals with a very specific profile. In this article, we try to understand the reluctance of savers and propose two types of explanation: the first relates to the public's distrust of banks and financial markets in general; the second is linked to the way in which professionals communicate about SRI in particular, praising its financial performance or resilience and generally refraining from committing themselves to extra-financial aspects.L’ISR est aujourd’hui bien implanté auprès des professionnels de la finance (gestionnaires de fonds ou investisseurs institutionnels) chez lesquels il rencontre un large succès. Toutefois, il peine à susciter le même engouement auprès du grand public, mis à part quelques particuliers au profil bien précis. Dans cet article, les auteurs1 essaient de comprendre les réticences des épargnants et proposent deux types d’explications : l’une renvoie à la défiance du public vis-à-vis des banques et des marchés financiers en général ; l’autre est liée à la façon dont les professionnels communiquent en particulier sur l’ISR en vantant ses performances financières ou sa résilience et en se gardant bien, le plus souvent, de s’engager sur les aspects extra-financiers
Using flexible crossdock schedules to face truck arrivals uncertainty
No full textInternational audienceThis paper discusses the use of robust schedules for facing uncertainty arising in crossdock truck scheduling problems. Groups of permutable operations bring sequential flexibility in the schedule, allowing to deal with late or early truck arrivals as the total order and the starting times can be determined in a reactive manner. We focus on the evaluation of a robust schedule considering both the worst maximal lateness of the trucks and the worst total sojourn time of the pallets. We also show how a robust schedule can be evaluated online, taking into account the actual arrival times of the trucks
Impacts of Risks Over Benefits in the Adoption of Self-Tracking Technologies
No full textInternational audienceSelf-tracking (ST) technologies offer an unlimited number of opportunities to improve human life, especially health and well-being. Many scholars have been interested in this technology because of its worldwide spread but have not emphasized the benefits versus ST practices risks. This paper presents a literature review of the benefits and risks of ST practices to close this gap. It also develops a multidisciplinary research model based on the extended valence framework. This model offers five hypotheses highlighting the importance of considering technological, social, and health factors when measuring ST adoption. The results show that the perceived benefits outweigh the risks. Health is paramount in the perception of benefits. These results lead the authors to make a few recommendations for practitioners
