On the design of fair environmental fiscal policies with workers heterogeneity : three essays in applied theory.

Summary This doctoral thesis studies, within a theoretical framework, the impact of environmental tax policies with respect to worker heterogeneity. It analyzes the construction of tax policies according to three objectives: reducing pollution emissions, improving efficiency, and reducing inequality. This thesis consists of an introduction and three chapters (academic articles), each of which examines this issue from different angles. The first chapter focuses on educational choices and analyzes the impact of environmental taxes on efficiency and equity through these educational choices. The second chapter focuses on the impact of environmental taxes in a context of labor market imperfection (frictional involuntary unemployment). The third chapter focuses on regional disparities in wages, employment and preference for polluting goods.
