[6]The construction of the national social protection policy in Madagascar: an inter-organizational network analysis (with Jean-Philippe Berrou, Alain Piveteau, Claire Gondard-Delcroix and Léo Delpy)
This article questions the form of the political compromise that underpins the development of the social protection policy in Madagascar. What coalition of actors is at stake, in a context where the economic and institutional conditions for the implementation of such a policy do not presently appear to exist (a "failed" state, declining economic capacities, an employment structure characterized by informality, etc.) ? It draws on the policy networks literature (Kapucu & al., 2017, Varone & al., 2016, Ingold, 2011; Laumann & Knoke, 1989) and proposes an analysis of the inter-organizational network of actors involved in the policy making process. Combining in a pragmatic approach different methods (nominalist and realistic) and tactics (Laumann, Marsden & Prensky, 1983), the specification of the complete network's boundaries start form the list of GTPS’ members from which some actors have been removed and others added. An original survey was conducted between 2018 and 2019 to interview key informants within each of these organizations. The sociometric questionnaire focuses on six types of relationships between actors: (i) collaborative links; (ii) information-sharing links; (iii) links of agreement on the orientations of the policy; (iv) links of disagreements on the orientations of the policy; (v) links of influence; (vi) interpersonal links. The collected data then make it possible identify within the policy making process of the social protection in Madagascar: the key actors with strong capacity for mobilization and influence, the emerging coalitions of actors, the main circuits for information circulation and resource exchanges.
[5]Effects of potential and active networks on the labour market outcomes: Empirical evidence from Colombia (with Jean-Philippe Berrou and François Combarnous).
Drawing from the socioeconomic literature on social networks and employment, we note that the definition of social network commonly used is ambiguous, referring to either potential or active networks. From this primary distinction, three issues appear crucial for seizing the real effect of networks on labour market outcomes: (i.) Do configurations based on potential or active networks’ dimensions matter? (ii.) What about the association between potential and active networks’ configurations? (iii.) What is the best combination between potential and active networks to improve the individual job performances? This paper offers to clarify these questions through an innovative empirical contribution. Using a specific multidimensional method and a quasi-experimental model on an original representative sample of 1600 workers in Bogota (Colombia), we provide empirical support that potential and active networks’ configurations matter and their combinations produce differential effects on the job search and matching.
[4]Opening the black box of weak ties: Information asymmetries and network-based job search (with Eric Quintane, Santiago Gomez and Javier Mejia).
This paper explores the relationship between tie strength and the outcomes of the job search process. We argue that two dimensions of tie strength (Frequency and Closeness) solve two distinct information problems (Incomplete information and information asymmetry) that can occur during the job search process. As a result, we propose that the alignment between the dimension of tie strength that connects the job seeker to her alters and the information problems that dominate the search process drives job search outcomes, such as salary increase, satisfaction and search time. We test our theory in a unique dataset, representative of the working population in Bogota, Colombia, of 1601 participants who recently found a new job through their social network. We distinguish between individuals who changes occupation and/or sector of activity to find their new job, thus facing an information asymmetry problem, and individuals who stayed in the same occupation and sector, facing an incomplete information problem. Our results support our theory. The alignment between the dimension of tie strength and the information problem to be solved affects individual’s satisfaction with their new job, their change in salary and the time that it took them to find a new job. We discuss the implications of our results for the literature on networks and job search.
[3]Utiliser les liens forts ou les liens faibles pour gagner plus ? Le cas du marché du travail de Bogota (Colombie) (with Jean-Philippe Berrou)
Depuis le travail pionnier de Granovetter (1973 ; [1974] 1995), l’association entre le contenu des relations et le revenu des individus sur le marché du travail constitue un point de débat important au sein de la sociologie économique de l’emploi et de l’analyse des réseaux sociaux, opposant la force des liens faibles à celle des liens forts. Cet article propose d’apporter une réponse théorique à cette question en considérant l’avantage des liens faibles pour résoudre un premier type de problèmes d’asymétrie d’information et celui des liens forts pour en régler un second. D’une part, l’accès à l’information sur les opportunités qui pourraient s’offrir aux acteurs et, par conséquent, sur les rémunérations qui leurs sont associées, constitue le premier type de problème d’asymétrie. De ce point de vue, les liens faibles seraient plus efficaces dans la mesure où ils permettraient de faire circuler une plus grande quantité d’informations et, de ce fait, accroître les chances d’obtenir un emploi assorti d’un meilleur revenu. D’autre part, le signalement des compétences et l’identification des meilleures opportunités représentent le second type de problèmes d’asymétrie, fréquemment associés dans la littérature à un changement d’emploi. Dans ce cas, les liens forts deviendraient les plus performants pour connaître une amélioration du revenu en raison de leur capacité à véhiculer une information plus complexe et/ou à garantir une recommandation crédible auprès des employeurs ou des partenaires. Nous vérifions empiriquement cette double proposition à l’aide de données collectées à Bogota (Colombie) sous la forme d’un système mixte en deux étapes : (i.) une enquête quantitative conduite sur 1600 travailleurs en 2016-2017 et (ii.) un approfondissement qualitatif réalisé à partir de 104 entretiens narratifs menés entre 2017 et 2018. Les résultats produits sur le marché du travail de la capitale colombienne tendent bien à confirmer l’idée d’une contextualisation de la force des liens et mettent plus particulièrement en évidence que (i.) les liens forts n’améliorent pas le revenu dans l’emploi actuel mais (ii.) permettent effectivement l’évolution substantielle du revenu entre la précédente et la nouvelle occupation.
