France stopped catching up with the United states standard of living in the early eighties, and has lost ground since then. This book studies French growth potential over a very long period: 1950-2030. It shows that France has not managed to adapt its growth trajectory to innovation-based competition and growth. The scenario discussed in the book for the period to 2030 is based on the hypothesis that France will implement a number of necessary reforms to adapt its growth model and be able to boost productivity.
