Foreign competition and quality upgrading: Evidence from French firms

by

Julien Martin and Isabelle Mejean describe quality upgrading by French firms in response to different forms of international competition:

What is the impact of low-wage countries’ competition on the quality of high-wage countries’ exports? To answer this question, we develop a new method that uses firm-level data to measure quality changes in sectoral exports. Over 1995-2005, we measure a 11% increase in the mean quality of France’s aggregate exports, driven by a reallocation of demand in favor of higher quality producers. The phenomenon is significantly more pronounced in markets where the penetration of developing countries has increased while it is negative where firms face increased competitive pressures from high-wage countries. These results are consistent with within-product specialization along the vertical dimension. They suggest that, over the period, France has specialized in the production of higher quality goods. In our data, around one fifth of the measured quality improvement in France’s aggregate exports is attributable to low-wage countries’ competition. In turn, its increasing specialization in higher quality goods has limited France’s market share loss over the period.

They’ve written a VoxEU column summarizing their findings.
