Exploring the effect of climate risk on agricultural and food stock prices: Fresh evidence from EMD-Based variable-lag transfer entropy analysis
No full textInternational audienceClimate has traditionally played an important role in the development of countries, owing to its inherent relationship with agricultural output and pricing. This study explores one such association between the most well-known climate anomaly, the El Niño34 Southern Oscillation, and international commodity prices of agriculture and food indexes. This study addresses the potentially causal effect of El Niño34 on international agricultural and food stock prices. To do so, we develop a novel approach: the empirical mode decomposition variable-lag transfer entropy (EMD-VL transfer entropy) by combining the variable-lag transfer entropy framework and the empirical mode decomposition. The evidence reveals the following major results. First, climate shocks affect global agricultural stock prices in the short-term. Second, significant transfer entropy from El Niño34 to food index appeared at mid- and long-term business cycles. Third, unidirectional causal effect from climate shocks to agricultural and food stock prices is more intense in the short business cycle attesting to the impact of climate shocks on the food market, which is especially visible in the short-term horizon. Finally, our proposed method exceeds the traditional variable-lag transfer entropy by detecting such causal interplay at various business cycles, which is useful for investors and policymakers

Exploring Frugal Innovation as an Ecodesign Strategy: A Case Study of a Water Access Solution at the BoP
No full textInternational audienceEcodesign strategies allow for addressing the economic and environmental impacts of a product. However, at the bottom of the pyramid, design considerations need to include the social sphere for a systemic approach to sustainability. Social entrepreneurs and small enterprises in emerging markets are setting new precedents for innovation. In environments where resources are scarce, they have developed innovative and affordable solutions focused on improving the quality of life of BoP communities. Known as frugal innovation, this approach has the potential to drive sustainable development. It involves using resources wisely to reduce costs without sacrificing value. Research on frugal innovation has made it possible to understand its origins, design criteria lists, and attributes. However, there is still a lack of understanding of the strategies implemented by local entrepreneurs in the BoP. The aim is to highlight the frugal innovation strategies implemented by local innovators under conditions of limited resources. Applying the case study methodology, an exploratory analysis of the development of a water access system in Mexico was carried out. Water scarcity is a major and urgent problem worldwide, particularly in marginalized areas. Data were collected through semi-structured in-depth interviews and a thematic analysis was carried out. We identified three main strategies: frugality, resource sharing, and integration of the human aspect of innovation. These frugal innovation strategies have the potential to enrich traditional Ecodesign practices. The results can serve as support and a set of tactics for entrepreneurs and academics interested in developing frugal innovation projects for BoP communities
Exploring resource seeking in a scientificcollaboration network and its effect on scientists' knowledge creation
No full textInternational audienceScientists display heterogeneous profiles regarding the focus of their knowledge production activities, their collaboration strategies and their outcomes. Despite increasing interests on research collaboration, little is known about how scientists mobilize their research network. In their knowledge creation efforts, scientists collaborate with colleagues from both academia and industry. These collaborations, leading or not to co-authorship, allow scientists to access to a number of research resources. The objective of this study is to explore whether and how knowledge production across the four Stokesâ quadrants (different focus on fundamental understandings and on immediate industrial and social application) is associated with specific modes of mobilizing research resources. This study examines empirically the relationship between scientific knowledge production, research resources and collaboration networks, using bibliometric and survey data on 116 scientists active in biotechnology in the Netherlands. Our results suggest that different knowledge creation objectives and outcomes are associated with particular ways of activating the network, and mobilize it to access specific research resources
Mentez-vous à votre banquier pour obtenir un prêt ? Vous n’êtes pas les seuls…

Cela représentait 13 % du montant total de leurs actifs. Plusieurs facteurs, sociétaux ou propres aux individus, favorisent l’endettement. Il y a, bien sûr, l’inflation, l’instabilité du taux directeur ou encore les inégalités sociales. Pour les 10 % des ménages les moins bien dotés, les dettes représentent jusqu’à 38 % de leurs actifs

A dynamic capability perspective of ambidexterity and itsimpact on international venture performance: Evidence from Nigerian industrial SMEs
No full textInternational audienceDigital technologies provide contemporary organizations with a unique opportunity to develop a new set ofdynamic capabilities to advance their business activities. For small- and medium-sized enterprises (SMEs) inparticular, technology can serve as a powerful force that can be used in order to meet the challenges imposedby larger competitors, especially in an international business context. The present study examines the role ofthree technology-related dynamic capabilities in influencing the international venture performance of SMEs, bysupporting their efforts to fully exploit their current products, knowledge, and processes (exploitationorientation) or by assisting them in developing new knowledge, introducing innovating offerings, and adoptingnovel business approaches (exploration orientation). Using data collected from Nigerian SMEs which operate ininternational markets, we find that digitalization capabilities, market capitalizing agility, and real-time marketresponsiveness have a positive impact on the pursuing of both an exploitation and exploration orientationtowards international business activities. We also indicate that an exploitation orientation (but not anexploration orientation) has a significant positive impact on international venture performanc
Les organisations rêvent-elles d'amour ? Les milles et un visages d'Eros au travail
No full textInternational audienceWhile it has made its way into other disciplines, from sociology to philosophy to political science, the issue of love is still repressed in management science. However, considering that the affective force of Eros is at the root organizational behavior is not as incongruous as it may seem. Through this essay, we want to explore this issue in the form of fragments, by sketching a few figures of this – as Barthes would call it – “lover’s discourse” in organizations.Alors qu’elle a fait de plein droit son entrée dans d’autres disciplines, de la sociologie à la philosophie en passant par les sciences politiques, la problématique de l’amour fait figure d’impensé pour les sciences de gestion. Pourtant, considérer que la force affective d’Eros soit au principe de nombreux comportements organisationnels n’est pas aussi incongru qu’il puisse y paraître. À travers cet article, les auteurs souhaitent palier cet oubli en explorant, sous forme de fragments, quelques figures – comme l’aurait dit Barthes – de ce « discours amoureux » dans les organisations
Measuring the performance of retailers during the COVID-19 pandemic: Embedding optimal control theory principles in a dynamic data envelopment analysis approach
No full textInternational audienceTraditional retailers (bricks-and-mortar) have been continuously increasing online sales. However, not all retail companies were able to respond to the increasing sales with the same efficiency level as their competitors. This paper aims to propose a dynamic model – incorporating principles of Optimal Control Theory (OCT) into a Data Envelopment Analysis (DEA) model - for measuring the performance of retailing companies’ cost efficiency. It also aims to contribute through the application by investigating the impact of the pandemic on companies from the most prominent developing market in Latin America, Brazil. Twenty-one companies publicly traded in the São Paulo Stock Exchanges (B3) between the third quarter of 2018 (3Q2018) and the third quarter of 2020 (3Q2020) were investigated. Also, six measures - initial inventory cost (IIC), final inventory cost (FIC), net operating income (NOI), cost of goods sold (COGS), cost of the purchased product (CPP), and plant, property, and equipment (PPE) – were considered. In this way, the findings have implications for researchers and practitioners. Practitioners can discover which competitor(s) is (are) adopting the best practices at each operational aspect (e.g., inventory cost). Additionally, the proposed method can be replicated in other markets (developing or not) and for other categories of retailing companies (e.g., small- and middle-sized). Further research directions are presented, and their implications are discussed
COVID-19 safety leadership, perceived severity, and emotional exhaustion: Does safety culture matter?
No full textInternational audienceIntroduction: Emotional exhaustion is a major health-related issue that employees face, especially during crises such as pandemics. This study seeks to understand how safety leadership applied to the COVID-19 pandemic relates to emotional exhaustion, and to examine its mechanisms (i.e., perceived severity) along with its boundary condition (i.e., safety culture). Method: A time lag study was conducted to collect data from 229 employees working in the service industry in Morocco. Data were analyzed through the Partial Least Squares Structural Equation Modeling (PLS-SEM) technique using SmartPLS 4. Results: The results demonstrate that safety leadership is negatively related to emotional exhaustion. Additionally, they suggest that the relationship between COVID-19 safety leadership and perceived severity depends on the level of the moderating variable (i.e., safety culture). Specifically, the relationship is positive when safety culture is low, but is negative when safety culture is high. Practical Applications: The results of this study are important as they extend our knowledge of the nature of safety leadership and emotional exhaustion, and offer managers practical implications that can help to optimize safety leadership practices
