[5] How much should we trust block modeling strategies to identify advocacy
coalitions in policy processes? A methodological proposal from two
Sub-Saharan policy networks (with J. Schlegel, O. Djibo, J-P. Berrou,
A. Piveteau)
Identify political coalitions is crucial to understand precisely a policy process. Focusing on the coalition phenomena, the Advocacy Coalition Framework (ACF) is a prominent theoretical approach offering recently a fertile articulation with the policy network analysis. These studies apply frequently Block Modeling and Community Detection (BMCD) strategies to define homogeneous political groups. However, the BMCD literature is growing quickly showing a large variety of algorithms and interesting selection methods much more diverse than the ones used in ACF. Thus, identify the best option can be difficult and few ACF studies give an explicit justification. On the other hand, few BMCD works offer a systematic comparison on real social networks and never applied to policy network datasets. The paper offers a relevant 4-Steps selection method to reconcile the ACF and BMCD advances. Using an application on original African policy network data collected in Madagascar and Niger, we provide a useful set of practical recommendations for future ACF works using network analysis: (i) the density and the size of the policy network affect the identification process, (ii) the “best algorithm” can be rigorously determined by maximizing a novel indicator based on the convergence and the homogeneity between algorithm results, (iii) researchers need to be careful with missing data, they affect the results and the implementation does not solve the problem.
[4] Transnational policy coalition(s) and the making of social protection
policy in Africa. An inter-organizational network analysis of the
National Social Protection Strategy of Madagascar (with J-P. Berrou,
A. Piveteau, C. Gondard-Delcroix and L. 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.
[3] Revising tie strength effect in Emerging countries' labor markets:
Reaching information or reducing asymmetry? Evidence from Colombia
(with J-P. Berrou)
The relevance of personal networks to explain how job markets work is commonly admitted by social scientists. However, the association between the strength of ties and labor outcomes constitutes one of the more debatable issues in economics and sociology. On the one hand, a long and known tradition following Granovetter's work (1973, 1975) demonstrates the strength of the weak ties (WT) to get a better job because of their capacity to convey novel informations. On the other hand, more and more studies show the strength of strong ties (ST) to increase labor market outcomes because having a strong contact and a recommendation is crucial like the Guanxi effect in China (Bian, 1997). Looking at this current opposition, we offer a possible articulation linking theory and institutional context. Theoretically, ties are considered as a fundamental institutional mechanism to solve numerous information problems and market failures. But the answer provided by the WT differs from the ST one. The WT are e cient in solving the reaching information problem whereas the ST are useful to reduce the asymmetric information issue. Finally, the value of WT or ST will depend largely on the more important issue in the specific labor market context. In this way, Emerging countries are marked by unequal labor systems, thus connecting disconnected groups through weak ties is crucial to get a better job. At the same time, emerging markets are particularly affected by institutional weaknesses, and solving the asymmetric information problem constitutes a fundamental step to climbing the labor ladder. We offer an empirical test with using mixed data recollected in Bogota (Colombia) 2016-2018. Firstly, based on a qualitative data recollected in Bogota (Colombia), we associate income variation and income mobility to both information problems in a Latin American context. Secondly, we offer a multidimensional index of the strength of ties and we use econometric models with and without instrumental variable in order to identify precisely the effect of WT and ST. Finally, our quantitative results confirm that having WT is useful to increase relative income, but ST are more relevant for climbing the income ladder. The WT effect works especially for lower-income people because information coming from other groups is particularly needed in an unequal context. However, ST generate deeper and higher-income mobility for all social groups by providing other kinds of resources. This result is in line with the qualitative exploration highlighting the relevance of the job recommendation as a crucial signal to move in the market affected by institional weaknesses. We discuss why conciliating WT and ST approaches is important to understand the stability of inequality in the Colombia contexts.
