The empirical relationship between competition intensity and the rate of productivity growth across 30 sectors of the French economy between 1978 and 2015 displays an inverted U-shape. This implies that there exists an optimal level of competition for each sector, defined by the price markup...

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...

We show that the relationship between the level of competition (the price markup) and the growth of labor productivity in 28 sectors of a panel of 8 euro area countries between 1995 and 2018 is consistent with an inverted U-shaped curve. We calculate an optimal price markup that maximizes...
