How and when voluntary citizenship behaviour towards individuals triggers vicious knowledge hiding: the roles of moral licensing and the mastery climate
No full textInternational audienceThe purpose of this paper is to investigate how voluntary citizenship behaviour towards anindividual (VCB-I) is linked with vicious knowledge hiding (VKH), and why members, within a masteryclimate, tend to participate in less VKH after their engaging in VCB-I. The authors, according to the morallicensing theory, propose that moral licensing mediates the relationship between VCB-I and VKH, andthat a mastery climate weakens the hypothesised link via moral licensing
Optimal ordering quantity under stochastic time-dependent price and demand with a supply disruption: A solution based on the change of measure technique
No full textInternational audienceThis paper presents a solution of a generalized newsvendor problem with supply disruption and dual sourcing, where the underlying product price and demand are correlated and evolve randomly over time. We contribute to the literature by employing a non-stationary model for demand, and proposing a novel solution methodology using the change of measure technique often applied for derivative pricing in the mathematical finance literature but not frequently considered in the management science and operations management literature. The application of this technique allows the non-linear expectation terms in the profit function, that are often computed numerically in the literature, to be determined analytically. This, in turn, leads to analytic solutions in special cases, and provides the foundations for a highly efficient numerical solution algorithm in general. A comparison against an alternative benchmark technique from the literature is provided to demonstrate the efficiency of our approach
The past, present and future of research on emotions in cross-cultural management
No full textInternational audienceThis paper presents a bibliometric and textual analysis of academic literature on emotions within the context of cross-cultural management. A bibliometric analysis uses co-citation and bibliographic coupling to reveal trends in the field, both past and present. Additionally, the Reinert lexicometric method is used to explore promising research directions as outlined in recent articles. The key findings suggest that the foundations of emotions in cross-cultural management lie in cultural and emotional intelligence, in the use of cultural dimensions as a framework for studying emotions, and in both international and psychological adaptation. These themes persist in current research with slight variations. Future research is expected to focus on empirical studies, developing theories of emotional intelligence, and contextual studies of acculturation, among other areas. Based on an integrative framework of emotions in cross-cultural management, we propose a research agenda and implications for practice
Efficience des PME agro-industrielles au Cameroun : une estimation par la méthode Data Envelopment Analysis (DEA)
No full textInternational audienceThe objective of this study is to measure the technical efficiency of agro-industrial SMEs. The DEA method was used to estimate efficiency scores on a sample of 311 SMEs from the INS database of Cameroon. The efficiency scores obtained using the CRS and VRS technologies for the entire sample were 32.81% and 53.39% on average, respectively. These efficiency scores show that Cameroon’s agro-industrial SMEs have a low level of technical efficiency. The results show that under CRS technology, the most efficient branch is forestry and logging, while under VRS technology, the best performance is achieved by the grain and starch powder manufacturing branch. The efficiency gains could have been achieved if all SMEs operated on the production frontier. To remedy this, two complementary solutions exist. One, external, is linked to the structuring of a collaboration with the managers of the non-efficient SMEs for the application of more adequate management methods; inspired by the SME benchmarks or reference groups. The other, internal, is related to the “conformity” of SMEs to the requirements of the socio-cultural environment.Cette étude a pour objectif de mesurer l’efficience technique des PME agro-industrielles. La méthode DEA a été utilisée pour estimer les scores d’efficience sur un échantillon de 311 PME issues de la base de données de l’INS du Cameroun. Les scores d’efficience obtenus selon les technologies CRS et VRS pour l’ensemble de l’échantillon sont respectivement de 32,81 % et 53,39 % en moyenne. Ces scores d’efficience nous ont permis de constater que les PME agro-industrielles du Cameroun ont un niveau d’efficience technique faible. Les résultats montrent que sous la technologie CRS, la branche la plus efficiente est celle de la sylviculture et l’exploitation forestière alors que sous la technologie VRS, c’est la branche du travail des grains et fabrication de poudres amylacées qui réalise la meilleure performance. Les gains d’efficience auraient pu être réalisés si toutes les PME opéraient sur la frontière de production. Pour y remédier, deux solutions complémentaires existent. L’une, externe, est liée à la structuration d’une collaboration avec les dirigeants des PME non efficientes pour l’application des méthodes de gestion plus adéquates ; en s’inspirant des PME benchmarks ou groupes de référence. L’autre, interne, est rattachée à la « conformité » des PME aux exigences de l’environnement socioculturel
Do foreign MNEs alleviate multidimensional poverty in developing countries?
No full textInternational audienceThis study investigates the effects of the investment-based presence of multinational enterprises (MNEs) on poverty in developing countries. The relationship is decomposed into different pathways corresponding to various facets of firms’ presence and activities, and monetary and multidimensional poverty. We hypothesize that depending on the pathways, the effects can be positive or negative in terms of poverty alleviation, and an overall conclusion has to be nuanced. The hypotheses are tested across 431 Indonesian administrative districts, observed in 2008, 2014 and 2018. Pooled instrumental variable regressions show that a higher presence of foreign MNEs does not reduce the number of people below the poverty line. It raises the depth and severity of poverty, and the population is also more exposed to pollutions. These results inform the ongoing debate, and offer important implications for policy makers eager to attract foreign direct investments, as well as for MNEs’ managers concerned with social responsibility and achieving sustainable development goals in host developing countries
Half Just or Half Unjust ? the Influence of Dispositional Optimism on the Link Between Interpersonal Peer Injustice, Negative Emotions and Sleep Problems
No full textNational audienceWhile optimism – a cognitive disposition that involves positive beliefs about the future – is a strong predictor of wellbeing at work, we know little about its role in how people experience and respond to injustice at work. In other words, does optimism mitigate or exacerbate the experience of workplace injustice? This is an important practical question because optimism is a promising avenue for interventions. Taking an affective events perspective, we expect that daily events of peer injustice trigger affective reactions, and that the degree of trait optimism will influence the strength of these affective reactions. Thus, we develop two competing predictions. The reverse buffer hypothesis, which suggests that optimists’ heightened expectations lead to increased disappointment and hence more negative emotions in the face of injustice, and the buffer hypothesis, which suggests that optimists’ better use of coping strategies allows them to experience less negative emotions. In a 10-day diary study with 251 employees, we find support for the buffer hypothesis of optimism on peer injustice experiences: those higher in optimism reported fewer negative emotions and lower levels of sleep problems the night following such experiences. Our findings illustrate how cognitive and emotional mechanisms interact in predicting reactions to injustice, particularly sleep problems
Investigating the unobserved heterogeneity effect on outreach to women: lessons from microfinance institutions
No full textInternational audienceThe main objective of this study is to assess the impact of unobserved heterogeneity on microfinance social efficiency analysis. Based on recent nonparametric techniques and directional distances, we identify a latent heterogeneity factor related to the microfinance institute (MFI) manager’s ability to promote women, independent of MFI size. We test for the significance of this unobserved factor and analyze the impact of MFI social inefficiency measures. Using a cross-country sample of 501 MFIs in 2011 from six main regions of the world, our findings reveal a significant effect of unobserved heterogeneity on the frontier and hence stress the importance of subjective factors in defining the set of production possibilities. We assess the robustness of our findings with the considered profit-oriented status and analyze the link between our unobserved heterogeneity factor and institutional and socioeconomic indicators
