Title of the thesis: Cost-benefit assessment policies
Superviser: Brice Laurent.
This thesis focuses on the use and development of cost-benefit analyses, i.e., methods used to estimate costs and benefits in order to inform decision-making or to evaluate a project, an innovation or a policy. These methods have been and are today used in a wide variety of fields (infrastructure, transport, health, environment, etc.). They are of interest to public and private actors who seek to measure the economic, social or environmental consequences of industrial projects or regulatory changes. The objective of the thesis is to analyze the construction and use of these methods in the French context and to study the controversies they entail. Several cases in different areas will be studied, especially in the field of transport.
