Abstract: [fre] Productivity gaps and « cost illness ». Contributions and limits of William J. Baumol's unbalanced growth model. . This paper exposes and analyses Baumol's unbalanced growth model, develo­ped in 1967. This model, which was revisited and empirically tested in 1985 by Baumol, Blackman and Wolff, tackles a subject that is still of great interest : productivity in the service sector. It emphasises the consequences on employment and growth of a productivity gap between the 'progressive' and 'non-progressive' sectors of the economy. Since the model is mainly concerned by the supply side, it faces some theoretical limits. The discussion of the propositions and the assumptions allows us to value the model's significance and to conclude that an analysis must incorporate both supply and demand aspects in order to really explain the mechanisms that determine production and employment in the different economic sectors..
