Richard H. Thaler et les limites de la rationalité

On October 9, 2017, Richard H. Thaler was awarded the Nobel Memorial Prize in Economic Sciences for his work in behavioral economics. The article presents his main contributions, namely the establishment of a list of anomalies of human behaviors from the perspective of rational models, the laying of foundations for a quasi-rational model inspired by psychology, and the approach to public policy commonly known as Nudge. As a conclusion, we more subjectively comment on the influence Thaler has had on the economic science, and speculate on a possible path forward for behavioral economics.
