Innovation sociale et enjeux de l’accessibilité numérique : le point de vue des professionnels du digital
No full textInternational audienceThis article examines the implementation of digital accessibility through the prism of social innovation literature. Digital accessibility desired for all (e-inclusion) thus appears through its process and its actors within organizations. The survey was conducted with 12 professionals from the digital sector and in charge of digital accessibility. It highlights their a priori goodwill in the face of the obstacles encountered in the field: time pressure, degree of willingness on the part of the company, technical and technological obstacles. The recommendations then encourage a social innovation that is not disconnected from technological innovations and a connection between the managerial field (micro level), organisational issues (meso level) and public policies (macro level).Cet article interroge la mise en œuvre de l’accessibilité numérique sous le prisme de la littérature dédiée à l’innovation sociale. L’accessibilité numérique voulue pour tous (e-inclusion) apparaît ici sous l’angle de son processus et de ses acteurs au sein des organisations. Notre démarche s’appuie sur une enquête conduite auprès de 12 professionnels du secteur digital, chargés de l’accessibilité numérique. Elle met en relief leur bonne volonté a priori face aux obstacles rencontrés sur le terrain en situation : pression temporelle, freins techniques et technologiques, degré de volonté de l’entreprise. Les recommandations alors formulées visent à favoriser une innovation sociale non déconnectée des innovations technologiques, assortie d’une connexion entre le terrain managérial au quotidien (niveau micro), les enjeux organisationnels (niveau méso) et les politiques publiques (niveau macro)
Experiencing defects: the moderating role of severity and warranty coverage on quality perceptions
No full textInternational audiencePurpose This study investigates two moderators of the effects of manufacturers' recovery efforts following a product defect on customers' perceptions of product quality: the severity of the product defect and whether the recovery efforts were covered under warranty or not. Design/methodology/approach A total of 478 USA customers who purchased a new car from a cooperating manufacturer participated in a survey. Customers reported the most important product defect (if any) the customers had experienced with the customers' vehicle during the past year. Three linear regressions (OLS) were used to test the proposed hypotheses. Findings Defect severity moderates the effects of recovery efforts on quality perceptions. The well-known recovery effect occurs only for product defects of minor severity. Experiencing a severe product defect damages the customers' perceptions of product quality even if the product defect is completely fixed. Double deviations (failed recovery of a product defect) do not damage quality perceptions for defects of minor severity. Finally, warranty coverage of repairs can attenuate the adverse effects of a failed recovery of severe defects on customers' quality perceptions. Additionally, only non-complainers who have experienced a severe product defect correspond to the prevailing conceptualization of an at-risk customer group. Originality/value Despite the pervasiveness of product defects, research on the effects of experiencing product defects on customers' product quality perceptions is scarce. Furthermore, the authors' findings reconcile inconsistent results and provide a more nuanced understanding of the well-known recovery and double-deviation effects. Finally, the role of warranty coverage in the recovery process as a buffer for customers' perceptions of product quality is novel
Quantile-based spillover connectedness among stochastic volatilities of ESG equities, Islamic and conventional stocks with implications for portfolio management
No full textInternational audiencePurpose This study aims to investigate the relationship between stock markets, environmental, social and governance (ESG) factors and Shariah-compliant in an integrated framework. Design/methodology/approach The authors employ the multivariate factor stochastic volatility (mvFSV) framework to extract the volatility of the different sectoral indices. Based on this evidence, the authors employ the quantile vector autoregressive (QVAR) approach to examine the dynamic spillover connectedness among the aforementioned indices. Findings The study emphasizes the following major findings: (1) significant time-varying spillover connectedness across quantiles, (2) bidirectional and asymmetric spillover effect among the ESG index and the other sectoral indices, (3) the strength of spillover connectedness is time-varying across quantiles, (4) based on the perspective of portfolio optimization, ESG market is a significant strong forecasting contributor to conventional and Shariah-compliant markets, (5) overall, the findings point out serious quantile pass-through effect among ESG index and the other sectoral indices during the COVID-19 health crisis. Originality/value This study extends the previous literature in the following ways. First, to the best of the researchers’ knowledge, none of the existing studies have investigated the relationship between stock markets, ESG factors and Shariah-compliant in an integrated framework. Second, this study extends the previous scholarships by applying the mvFSV. Third, the authors propose a new rolling version to estimate dynamic spillovers, namely the rolling-window quantile VAR method. This approach provides a great advantage in computing the dynamics of return and variance spillover between variables in terms not only of the overall factor but also of the net (pairwise) aspect
La justice organisationnelle dans les entretiens d’embauche : Analyse d’un paradoxe de justice
No full textInternational audienceThis paper is intended for human resource managers involved in the selection of new employees. The article deals with organizational justice (OJ) in the recruitment process. It develops the principles of OJ and their application in recruitment. Then, the paper considers more precisely the selection interview because it is the most widely used recruitment tool by companies. It analyzes unstructured and structured interviews in terms of procedural and interactional justice. Applied to these two types of interview according to Gilliland’s Model (1993), the study demonstrates how and why the unstructured interview, which does not meet the requirements of procedural justice (unlike structured interviews), is perceived by candidates as fair. Therefore, Organizational Justice and Perceived Organizational Justice contradict each other. Indeed, while certain conditions of organizational justice are respected during structured interviews, candidates may not perceive the process as being fair. Thus, the paper highlights a situation of «justice paradox» or «justice dilemma» and proposes to improve the perception of justice in structured interviews. Finally, the article recommends a model to overcome this paradox in the structured selection interview. The main recommendations are based on the opportunity to express the voice of the candidate especially at the beginning and at the end of the interview, incorporating rapport building and open question. In relation to these proposals, future research could develop case studies to integrate the social, economic and cross-cultural perspectives of our proposals.Cet article s’adresse aux responsables des ressources humaines impliqués dans la sélection de nouveaux employés. L’article traite de la justice organisationnelle (JO) appliqué processus de recrutement au regard des principes de JO. Ensuite, le papier considère particulièrement l’entretien de sélection en tant qu’outil de recrutement le plus utilisé par les organisations. Ainsi, il analyse les entretiens non structurés et structurés sous le prisme de la justice procédurale et interactionnelle. Relativement à ces deux types d’entretien, l’étude démontre, selon le modèle de Gilliland (1993), comment et pourquoi l’entretien non structuré, qui ne répond pas aux exigences de la justice procédurale (contrairement aux entretiens structurés), est perçu par les candidats comme équitable. Autrement dit, justice organisationnelle et justice organisationnelle perçue se contredisent. En effet, si certaines conditions de justice organisationnelle sont respectées lors des entretiens structurés, les candidats peuvent ne pas percevoir le processus comme étant équitable. Ainsi, l’article met en évidence une situation de «paradoxe de justice» ou de «dilemme de justice» et propose d’améliorer la perception de JO dans les entretiens structurés. C’est pourquoi, le papier recommande un modèle pour surmonter ce paradoxe lors de l’entretien structuré. Les principales recommandations sont basées sur la justice interactionnelle en donnant l’opportunité au candidat de s’exprimer, notamment au début et à la fin de l’entretien, ainsi que par des questions ouvertes. En lien avec ces propositions, les recherches futures pourraient développer des études de cas afin d’étudier les perspectives sociales, économiques et interculturelles de nos propositions

Price magnitude, trading behavior and mispricing: An experiment
No full textEmpirical evidence shows that stock price magnitude influences portfolio choices and/or future returns, an observation at odds with standard finance theory. Authors most often refer to stock characteristics like a high variance and a positive skewness of returns to justify this result. In this paper, we use an experimental setting to demonstrate that price magnitude impacts investors behavior and market mispricing, independently of the distribution of future returns. Our results show that lottery-like features or perceived skewness are not enough to explain the role of price magnitude. We interpret this anomaly in the light of the neuropsychological theory of the perception of numbers by the human brain. Our experimental market design allows us to show that subjects process "small"and "large"prices differently, everything else being equal, in particular the objective distribution of future returns. Two consecutive treatments are performed, one with a fundamental value equal to 6 (small price market) and one with a fundamental value equal to 72 (large price market). The small price market exhibits greater mispricing than the large price market. Our findings cannot be explained by stock characteristics (lottery-like features or perceived skewness); the price magnitude in itself has a direct impact on how the subjects' brain perceive the distribution of future returns. Though at odds with standard finance theory, our findings are consistent with: (1) evidence in neuropsychology on the use of different mental scales for small and large numbers, and (2) empirical results in the finance literature
Mapping borrowers’ and lenders’ interactions according to their dark financial profiles
No full textInternational audienceIn this interdisciplinary, conceptual article with implications in marketing fnancial products and services, we study real estate and capital markets characterized by a predatory paradigm and economic agents’ dark fnancial profles (DFPs). These are estimated by three orthogonal components—disconnection, irrationality, and deceit. We identify the best interactional patterns of borrower-lender profles, ones that expectedly minimize the risk of default. We resort to discretized, predator–prey Lotka–Volterra equations where lenders act as predators and borrowers as prey, incorporating market trends and learning efects. To mathematically operationalize our framework, we use combinatorics with high, medium, and low levels of the three components of DFPs. We fnd 27 salient lender-borrower interactional scenarios and observe three diferent patterns: explosive, conducive, and implosive. Our theoretical fndings indicate that equal (ir)rationality (in fnancial terms) between lenders and borrowers is a necessary but insufcient condition to maintain harmonious, long-term relationships. We use eutectic theory to map the agents’ profles by introducing another variable: Expected return [E(Rp)] versus risk [σ], using the Capital Asset Pricing Model (CAPM) as a base. We fnd six market segments: the inactive predators and prey, the loose, the greedy, the vulnerable, and the stable. We identify the optimal combination of borrowers–lenders interaction under risk, given market trends and learning efects. We propose a path for future research that would see the application of analytical tools such as factor analysis, k-means clustering algorithm, χ2 and non-parametric Kruskal–Wallis and Dunn’s multiple comparison tests to verify diferences among the hypothesized segments
