Abstract : Local labour markets are characterized by mismatches, especially for people furthest from the job market. To solve these problems, public and/or private stakeholders implement policies that we shall call "Local Institutional Arrangements" (LIA). The aim of our research is to develop an institutional analytical framework of the LIA which complements "outcome evaluations" by focusing on "monitoring evaluation". Our methodology takes into account the existence of relationships of trust, of incentive/control systems, and of local and global institutional environments. It allows us to analyze stakeholders' coordination within LIA. We use our analytical framework to assess two LIA : the Poitou-Charentes region vocational training policy, "Service Public Régional de Formation professionnelle", and the social experiment "Groupement d'Activités" in Nantes/Saint-Nazaire and Touraine. Beyond the results concerning each arrangement, we observe two main regularities. The processes of implementation are affected by the existence and the nature of contractual relations, on the one hand, and by continued tensions between local and global "rules of the game", on the other hand.
