Evaluer le coût des politiques climatiques de l'importance des mécanismes de second rang

Abstract : The thesis shows how second-best mechanisms (labour markets rigidities, imperfect foresight) and mechanisms considered as short-term issues (inertia of productive capital, unemployment) induce that (i) mitigation costs are transition costs insofar as policies to reorient investments to low-carbon infrastructures are implemented early to avoid lock-ins in high-carbon development paths ; (ii) these transition costs can be signi cant, in particular for emerging and developing countries. Therefore, representing real world rigidities in energy-economy-environment models has important implications for the analysis of climate policies. Equalizing carbon prices is not anymore the policy minizing mitigation costs if a second-best world is considered. The thesis thus illustrates that the package worldwide carbon price plus compensatory transfers cannot lead, by itself, to a palatable deal for emerging and developing countries. It insists on the necessity to design alternative policies to open the control variables palette (public investments, infrastructures, scal reforms) and allowing specic policies at the local level.
