The aim of the project was to compare productivity in services in France and the United States, and in particular to ascertain whether productivity in services was indeed weaker and productivity gains lower in the United States than in France and whether this could explain the very high levels of job creation in the American service sector and the relatively modest levels in France. This interpretation was very widespread in the early 1990s and is still advanced today. According to our findings, this explanation is, for the most part, an illusion and the main answers to the question are conceptual and methodological in nature. Furthermore, by showing the limits of the traditional concepts in the case of an international comparison, useful pointers can be gleaned as to how to interpret the so-called ‘productivity paradox’ in each country. Why to publish, ten years later, a synthesis of these findings? Because almost nothing changed during the 1990s, either on the conceptual issue, or on that of the productivity trends: the average annual productivity gains in services (as actually measured) remained very low and sometimes negative in the United States during the 1990s,1 and they were lower than in France.
