Économie de l’environnement et des ressources naturelles : Introduction
No full textInternational audienceEn près de dix ans d’existence, l’Association française des économistes de l’environnement et des ressources naturelles (Faere) a su fédérer une large population de chercheurs, tant français qu’étrangers, autour de problématiques qui sont plus que jamais au cœur des grands débats de nos sociétés. La conférence annuelle de l’association est l’occasion de discuter des développements les plus récents de ces recherches. Ce numéro de la Revue française d’économie propose un aperçu des travaux présentés lors de la conférence de 2021, organisée par l’université Grenoble Alpes et le GAEL
Meta Partial Benders Decomposition for the Logistics Service Network Design Problem
No full textInternational audienceSupply chain transportation operations often account for a large proportion of product total cost to market. Such operations can be optimized by solving the Logistics Service Network Design Problem (LSNDP), wherein a logistics service provider seeks to cost-effectively source and fulfill customer demands of products within a multi-echelon distribution network. However, many industrial settings yield instances of the LSNDP that are too large to be solved in reasonable run-times by off-the-shelf optimization solvers. We introduce an exact Benders decomposition algorithm based on partial decompositions that strengthen the master problem with information derived from aggregating subproblem data. More specifically, the proposed Meta Partial Benders Decomposition intelligently switches from one master problem to another by changing both the amount of subproblem information to include in the master as well as how it is aggregated. Through an extensive computational study, we show that the approach outperforms existing benchmark methods and we demonstrate the benefits of dynamically refining the master problem in the course of a partial Benders decomposition-based scheme

Predicting attitudinal and behavioral responses to COVID-19 pandemic using machine learning
No full textInternational audienceAt the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions. In this study, we applied machine learning on the multi-national data collected by the International Collaboration on the Social and Moral Psychology of COVID-19 (N = 51,404) to test the predictive efficacy of constructs from social, moral, cognitive, and personality psychology, as well as socio-demographic factors, in the attitudinal and behavioral responses to the pandemic. The results point to several valuable insights. Internalized moral identity provided the most consistent predictive contribution—individuals perceiving moral traits as central to their self-concept reported higher adherence to preventive measures. Similar was found for morality as cooperation, symbolized moral identity, self-control, open-mindedness, collective narcissism, while the inverse relationship was evident for the endorsement of conspiracy theories. However, we also found a non-negligible variability in the explained variance and predictive contributions with respect to macro-level factors such as the pandemic stage or cultural region. Overall, the results underscore the importance of morality-related and contextual factors in understanding adherence to public health recommendations during the pandemic
Une comparaison des sanctions en droit financier, droit des données personnelles et droit de la concurrence
No full textNational audienceLes évolutions les plus remarquables du droit répressif visant les entreprises sont un accroissement très fort des sanctions pécuniaires encourues qui peuvent aujourd’hui atteindre des milliards d’euros et une multiplication des autorités non-judiciaires susceptibles de prononcer des sanctions. Les entreprises du secteur financier sont particulièrement exposées au risque de sanctions prononcées par des autorités administratives, de régulation ou de contrôle parce qu’elles sont traditionnellement placées sous la supervision scrupuleuse des autorités de régulation des activités et des acteurs financiers et parce qu’elles sont aussi éminemment concernées par les réglementations transectorielles assorties de sanctions comme le droit de la concurrence et le droit des données personnelles, en raison de leur poids sur leurs marchés respectifs et en raison du rôle essentiel que jouent la collecte, le traitement et l’exploitation des données dans les activités des entreprises financières
‘You are free to choose . . . are you?’ Organisational punishment as a productivity incentive in the social science literature
No full textInternational audienceThis article investigates the theoretical and empirical relationships between organisational punishment and productivity. We do so by highlighting the contributions of two academic fields to this topic: management and economics. We underscore the many common theoretical and empirical grounds across management and economics. We heighten, in particular, how motivation and learning theories have contributed to the development of both theoretical and empirical research on this topic. This article also argues that this debate could be significantly advanced if insights stemming from industrial relations and labour process theory were also considered, as these disciplines have traditionally focused on macro-issues such as how changes in the economic/institutional contexts may affect the likelihood that organisations will resort to punishment. In order to foster future research on this topic, three research themes were developed: (a) freedom of choice and the role of contract completeness; (b) perception of punishment, monitoring and productivity; and (c) punishment, productivity and exogenous variables

Complexity of flow time minimization in a crossdock truck scheduling problem with asymmetric handover relations
No full textInternational audienceWe address a novel truck scheduling problem arising in crossdocking logistics, in which inbound trucks carry items (pallets) which must be sorted and loaded onto outbound trucks. We minimize the utilisation of the warehouse by focusing on the synchronisation between the different related trucks. The problem is to assign the trucks to the doors of the warehouse and sequence them, in order to minimize the total time spent in the system by the pallets. We discuss the complexity of the problem, showing that even with a single door the problem is NP-hard in general, and discuss some special cases
