In an analysis of the reasons for the low rate of economic growth in France, Jacques Bely emphasizes here how unhelpful it is to look for answers in contrasting the public and private sectors. In his view, an increase in the rate of economic growth will be achieved not by privatising certain public services but by improving their efficiency. Bely argues that the failure of public services to take account of this "efficiency factor" leads to a need for even greater productivity on the part of the market and competitive sector, thereby impairing the contribution of the latter to fostering growth. It is therefore essential for the French public services to acknowledge this efficiency dimension and take their inspiration from businesses in making organizational changes that will provide greater customer satisfaction at lower costs. This is one of the keys to reviving French economic growth, says Bely, and he offers some concrete proposals at the end of the article.
