Incertitude, inertie et choix optimal : modèles de contrôle optimal appliqués au choix de politiques de réduction des émissions de gaz à effet de serre

Abstract : I propose a calibrated description of the economic inertia for the DICE model. Results suggest that greater efforts of abatement should be undertaken. Further, dynamic and static marginal abatement costs differ, which fosters a discussion about the level of the price-signal. The "irreversibility effect" is my first topic concerning decision-making under risk. The formalism proposed ties together many conditions that are scattered in the literature. A new sufficient condition about the value of information is obtened. Secondly, information structures are represented as a family of "random measures" (sensors) and marginal value of information is studied. New conditions for the Radner-Stiglitz theorem are obtened and imposed separately on the family of information structures and on the utility function.
