Commande publique et entreprises en difficulté : vade mecum du maintien de l’activité
No full textL’entreprise en difficulté n’agit pas toujours dans la sphère purement privée de notre économie. Par leurs commandes publiques, les personnes publiques et même un nombre non négligeable de personnes privées font vivre partiellement ou totalement des centaines d’entreprises. Lorsque l’une d’entre-elles est en difficulté, elle se trouve confrontée à la gestion de ces cocontractants spéciaux que sont les pouvoirs adjudicateurs. Lorsqu’il est encore temps de maintenir l’activité de l’entreprise, les spécificités sont nombreuses dans la gestion de ces contrats, et cela aussi bien au stade de la soumission aux marchés publics (I), qu’au stade de l’exécution des marchés publics en cours en période d’observation (II), ou, enfin, lorsqu’il s’agit de céder ces contrats publics en plan de cession (III)
Contrats de concession de main d'œuvre pénale : quand la concession cache la relation de travail
No full textTratamiento informativo de la Covid-19 en el servicio audiovisual público. Comparativa entre los medios online RTVE.es y Francetvinfo.fr News coverage on Covid-19 in public broadcasting. Comparison between RTVE. es and Francetvinfo.fr online media
No full textThis article studies the news coverage of the pandemic generated by Covid-19 in public service media in Spain and France. Through analysis of the headlines, sources used and a study of their statements, it reflects on the mediatization of this crisis during its first wave in two Mediterranean countries. The corpus, comprising news on Covid-19 or coronavirus on RTVE.es (17.031) and Francetvinfo.fr (14.492), broadcast between January 15 2020, and 15 June 2020, was selected through quantitative analysis. Once counted, 70 units were randomly selected in each medium for in-depth content analysis. The results show that, in both cases, coverage of the pandemic in the first wave conveyed a large amount of information every day. For preference, government sources are used, alternating, especially in the French environment, with expert and health sources. The story, both from sources and that of the journalists, varies depending on the evolution of the pandemic
On the foundations of ex post incentive compatible mechanisms
No full textIn private-value auction environments, Chung and Ely (2007) establish maxmin and Bayesian foundations for dominant-strategy mechanisms. We first show that similar foundation results for ex post mechanisms hold true even with interdependent values if the interdependence is only cardinal. This includes, for example, the one-dimensional environments of Dasgupta and Maskin (2000) and Bergemann and Morris (2009b). Conversely, if the environment exhibits ordinal interdependence, which is typically the case with multi-dimensional environments (e.g., a player’s private informatio
Recycling under environmental, climate and resource constraints
No full textThis paper investigates the recycling opportunities of an industrial sector constrained by resource, climate, and waste capacities. To do this, we model the full lifecycle of a good to consider the waste and greenhouse gas (GHG) emissions coming from both its production — from virgin or recycled materials — and consumption. We identify the optimal trajectories of resources use, mainly depending on the relative scarcity of the resources and on their emissions. Although recycling is usually, and correctly, noted as an opportunity to reduce the impact of consumption on primary resources and waste, we also consider the possible negative environmental consequences of recycling and we discuss the resulting arbitrations. We characterize the optimal recycling strategy and we show that, in some cases, the recycling rate through time is an inverted U-shape, and there can be a catch-up phase of consumption at the end of the social planner program. Finally, we discuss the policy implications of our model by identifying and analyzing the set of optimal tax-subsidy schemes, and we highlight the existence of standard environmental externalities as well as a positive externality linked to the absence of a market for waste
The evolution of mechanisms to produce phenotypic heterogeneity in microorganisms
No full textIn bacteria and other microorganisms, the cells within a population often show extreme phenotypic variation. Different species use different mechanisms to determine how distinct phenotypes are allocated between individuals, including coordinated, random, and genetic determination. However, it is not clear if this diversity in mechanisms is adaptive—arising because different mechanisms are favoured in different environments—or is merely the result of non-adaptive artifacts of evolution. We use theoretical models to analyse the relative advantages of the two dominant mechanisms to divide labour between reproductives and helpers in microorganisms. We show that coordinated specialisation is more likely to evolve over random specialisation in well-mixed groups when: (i) social groups are small; (ii) helping is more “essential”; and (iii) there is a low metabolic cost to coordination. We find analogous results when we allow for spatial structure with a more detailed model of cellular filaments. More generally, this work shows how diversity in the mechanisms to produce phenotypic heterogeneity could have arisen as adaptations to different environments

L'infléchissement du principe d'interdiction de cumul de qualifications infractionnelles pour les mêmes faits
No full textLes juristes ne savent que trop bien que le latin ne prend pas toujours sa source à Rome. Aussi faut-il se méfier de ces belles formules lapidaires qui paraissent condenser une règle intemporelle et inaltérable ; malgré leur apparence, ces formules sont parfois terriblement contemporaines, tant par leur nécessité que par leur insuffisance à régler des problèmes nés d'un recours immodéré au droit pénal par le législateur durant ces dernières décennies. S'il semble évident qu'il n'est pas justifié de punir deux fois la même personne pour la même chose, ne/non bis in idem, encore faut-il comprendre la raison et mesurer la portée de cet impératif. En adoptant ce principe comme base de l'interdiction des cumuls de qualifications infractionnelles, en 2016(1), la chambre criminelle de la Cour de cassation n'a fait que débuter un travail qui risque d'exiger encore bien des décisions à la motivation enrichie, à l'instar d'un arrêt rendu par sa formation plénière le 15 décembre 2021(2)
