Competition, Technological Change and Productivity Gains: A Sectoral Analysis

Stephane Ciriani, Orange, François Jeanjean, Orange addresses Competition, Technological Change and Productivity Gains: A Sectoral Analysis.

ABSTRACT: This paper addresses the empirical relationship between the level of competition and the rate of productivity growth across thirty sectors of the French production system during the period 1978-2015. It shows that there exists an optimal level of competition for each sector that is defined by the mark-up that maximizes the growth rate of labor productivity. The persistence of nonoptimal mark-ups in French sectors is associated with a 0.4% loss in aggregate average annual labor productivity growth during the period (1.86%). Hence, long-term productivity growth could have reached 2.25% if mark-ups had been at their optimal level. There is a strong significant positive correlation between the optimal mark-up and the rate of Hicks-neutral technical progress in each sector. This finding implies that sectors with high technical progress require higher mark-ups to maximize their rate of labor productivity growth. Overall, the aggregate economy would benefit from a decrease in the gap between nonoptimal and optimal mark-ups, as such an alignment would foster productivity growth.
