Quand le design social croise le design fiction pour anticiper les risques naturels de la ville de demain
No full textInternational audienceLa multiplication des évènements climatiques extrêmes tels que les canicules et les sécheresses, caractérisés par un bornage temporel diffus et une représentation visuelle qui peine à s’incarner, nécessite de s’interroger sur leur inscription dans un imaginaire collectif. En s’appuyant sur deux projets : un projet de recherche (ANR Inplic) et un projet pédagogique avec des étudiant.es du master Design, Innovation Société (université de Nîmes), cet article analyse les croisements fertiles entre design fiction et design social pour nourrir une réflexion ouvrant sur une troisième voie, située entre l’utopie et la dystopie et répondant à la nécessité d’engendrer des actions collectives face aux urgences environnementales
Towards social network metrics for supply network circularity
No full textInternational audiencePurpose Despite the systemic nature of circular economy (CE), theorisation that draws from a supply network perspective is only incipient. Moreover, the operations and supply chain management (OSCM) field has engaged in little dialogue with circularity. This study explores social network analysis (SNA) to depict how the shift from linear to circular not only leads to higher rates of resource economy, repair and recycle but also reshapes governance dynamics and network structure of supply networks. Design/methodology/approach The study departs from a systematic review of the literature and draws from core concepts in OSCM, CE and SNA to offer theoretical propositions that articulate how social network metrics can depict supply network circularity. The framework is illustrated with examples from fashion and electronics industries. Findings Four theoretical propositions enlighten how betweenness centrality, eigenvector centrality and network density can explain the shift from linear to circular supply networks across the three CE strategies of narrowing, slowing and closing. Originality/value The combination of biomimicry, CE, the push–pull dichotomy and social network metrics offer a theory-driven framework for supply network circularity
Green Practices and Customer Evaluations of the Service Experience: The Moderating Roles of External Environmental Factors and Firm Characteristics
No full textInternational audienceGiven that services differ from goods in terms of intangibility, heterogeneity, and inseparability, customers may evaluate green services differently from how they evaluate green goods. Previous research has investigated customers' perceptions and purchase decisions regarding green products. However, limited attention has been paid to the impact of green practices on customer evaluations of the service experience as well as important contingencies that bear on this relationship. Drawing on stakeholder theory, our study examines the impact of green practices on customer evaluations and further considers the influences of environmentaland firm-level contingencies. We test our model with a multi-source dataset in the Chinese hotel industry. The findings indicate that green practices improve customer evaluations of the service experience. This positive impact is, however, weaker in external environments characterized by high internet penetration and market complexity but is stronger for hotels with innovative services and for business hotels. Our findings provide novel insights into the environmental ethics and stakeholder management literatures by revealing the role of green practices in promoting positive service evaluations as well as the contingent influences of external environments and internal firm-level characteristics
Making honest men of them: Institutional investors, financial reporting, and the appointment of female directors to all-male boards
No full textInternational audienceIn this paper, we theorize that dedicated institutional investors are more likely than transient institutional investors to appoint female directors to investee firms with all-male boards, particularly those with high opacity. We conjecture that dedicated investors appoint female directors as a governance mechanism to improve the financial reporting quality of these investee firms. Specifically, we find that through the appointment of female directors, dedicated institutional investors trigger the release of stockpiled negative accounting information, thereby increasing the likelihood of a stock price crash risk. We also show that dedicated investors, through the appointment of female directors, improve investee firms' corporate disclosure environment by decreasing earnings management. Finally, we find that through continued service on investee firms' boards, female directors reduce the future likelihood of a stock price crash
Performance feedback and export intensity of Chinese private firms: Moderating roles of institution-related factors
No full textInternational audienceBuilding on the behavioral theory of the firm and institutional view, we examine how performance feedback (i.e., a focal firm's performance relative to its industry peers) affects export intensity and how institution-related factors moderate this relationship. Using a sample of Chinese private manufacturing firms, we find that positive performance feedback lowers export intensity while the relationship between negative performance feedback and export intensity is insignificant. Moreover, outperforming firms are likely to decrease their export intensity even more when they are located in regions of better institutional development or have political connections. Underperforming firms with political connections tend to increase their export intensity. These findings enrich our understanding of the export behavior of emerging market firms
Oil price shocks and stock market anomalies
No full textInternational audienceThis paper provides a novel perspective to the nexus of oil prices and stock markets by examining the impact of oil price shocks on stock market anomalies. After decomposing oil price shocks into three types (Kilian, 2009), we find that aggregate demand shocks have the strongest influence on stock market anomalies. In contrast, oil supply shocks and oil specific demand shocks have little impact. Similar results are also found in the industry analysis. Interestingly, the link between aggregate demand shocks and anomalies are the strongest among firms with either small size or high idiosyncratic risks. The documented effects are robust after controlling for investor sentiment as well as several well-known macroeconomic or market factors. Our findings are consistent with but also extend the results of Stambaugh, Yu, and Yuan (2012) in that we show that uncertainty also plays a role in explaining stock market anomalies
The role of ESG in the decision to stay or leave the market of an invading country: The case of Russia
No full textInternational audienceWe study firms' decisions to stay or leave the Russian market amid the invasion of Ukraine. Lower ESG scores increase the likelihood of keeping the Russian operations unchanged. Higher scores lead to less negative stock market reactions following complete exits

Swimming against the tide: supplier bridging roles in diffusing sustainability upstream and downstream in supply networks
No full textInternational audiencePurpose This paper aims to investigate the bridging role of first-tier suppliers in diffusing sustainability in supply networks and how this role is facilitated by the procurement function. Design/methodology/approach The paper is based on an embedded case study of two supply networks of a coffee beans roasting company. The embedded cases focus on coffee beans and packaging supply networks. Findings The findings reveal less than expected involvement of the focal company and its procurement function in sustainability implementation with first-tier suppliers. Instead, sustainability diffuses upstream to lower-tier suppliers but also downstream, against the tide, as a result of the various bridging roles performed by first-tier suppliers. Research limitations/implications This paper provides two theoretical contributions. First, it contributes to the sustainable supply network management literature by providing rich insights on sustainability diffusion to lower-tier suppliers and the role of first-tier suppliers in this process. Second, the paper contributes to structural hole theory by revealing a typology of bridging roles that actors, such as suppliers, undertake in the sustainability context. Practical implications The paper provides managers with practical insights on how sustainability can be diffused in the supply network and the different roles that first-tier suppliers can play in this direction. Originality/value This paper shows that sustainability diffusion to lower-tier suppliers is possible in the absence of focal company procurement involvement when bridging roles are undertaken by first-tier suppliers and their procurement functions are involved in the implementation process. These bridging roles facilitate sustainability diffusion both upstream and downstream
