This thesis aims at measuring the effects of innovation policies. It first focuses on the effects of the European Union (EU) policy titled Framework Programmes for Research and Development (FPs) on the regional innovation of the EU 27 countries. Thereafter, it brings a deep analysis of the effects of the French Competitiveness Clusters policy on firms' innovation process and on their performances.The originality of the thesis lies in the mobilization of innovative macro and micro-econometric techniques to evaluate public policies. The results of this work will inform the role and effectiveness of the Framework Programmes for Research and Development in regional innovation dynamics, but also the effectiveness of the Competitiveness Clusters policy on French firms' performances in terms of innovation, incentives for private investments, job creation and market competitiveness. ; Cette thèse a pour objectif de mesurer les effets des politiques d'innovation. D'abord, elle se penche sur les effets de la politique de l'Union Européenne intitulée Programmes Cadres de Recherche et Développement (PCRDT) sur l'innovation des régions des 27 pays de l'Union Européenne. Ensuite, elle apporte une analyse approfondie des effets des Pôles de Compétitivité sur le processus d'innovation des entreprises françaises et leurs performances.L'originalité de la thèse réside essentiellement dans la mobilisation de techniques novatrices d'évaluation macro et micro-économétriques des politiques publiques. Les résultats de ces travaux éclaireront le rôle et l'efficacité des Programmes Cadres de Recherche et Développement dans les dynamiques régionales d'innovation mais également l'efficacité de la politique des Pôles de Compétitivité sur les performances des entreprises françaises en termes d'innovation, d'incitation à l'investissement privée, de création d'emploi et de compétitivité sur le marché.

We analyze financial markets in which agents face differential constraints on the set of assets in which they can trade. In particular, the assets available to each agent span a partition of the state space, which can be strictly coarser than the partition spanned by the assets available in the market. We first show that the existence of differential constraints has an impact on prices and allocations as compared to a complete financial market with unconstrained agents. We consider the implications for survival, taking the work of Blume and Easley (2006) as a starting point. We show that whenever agents have identical correct beliefs and equal discount factors, and their partitions are nested, all agents survive. When agents have heterogeneous beliefs, differential constraints may allow agents with wrong beliefs to survive. Provided constraints are relevant (in a sense we define more precisely), the condition for an agent to survive is that his survival index is at least as large as that of the agents with finer partitions. We also study the impact of deregulation (an increase in the set of assets available to some agents). Unless the agent can adopt beliefs that are closer to the truth on the newly refined partition than those of less constrained agents, increasing his opportunities for trade might harm his chances for survival.
