Immigrants' Wage Performance in a Routine BiasedcTechnological Change Era: France 1994-2012

Over the period 1994-2012, immigrants' wage growth in France has outperformed that of natives on average by more than 14 percentage points. This striking wage growth performance occurs despite similar changes in employment shares along the occupational wage ladder. In this paper we investigate the sources of immigrants' relative wage performance focusing on the role of occupational tasks. We rst show that immigrants' higher wage growth is not driven by more favorable changes in general skills (measured by age, education and residence duration), and then investigate to what extent changes in task-speci c returns to skills have contributed to the differential wage dynamics through two different channels: different changes in the valuation of skills (\price effect") and different occupational sorting (\quantity effect"). We nd that the wage growth premium of immigrants is not explained by different changes in returns to skills across occupational tasks but rather by the progressive reallocation of immigrants towards tasks whose returns have increased over time. Immigrants seem to have taken advantage of ongoing labor demand restructuring driven by globalization and technological change. In addition immigrants' wages have been relatively more affected by minimum wage increases, due to their higher concentration in this part of the wage distribution
