TALE OF TWO COUNTRIES: TWO STORIES OF JOB POLARIZATION
Résumé
The US and French job polarization appear similar based on employment shares by task. This study shows that they are different when per capita employment by task is used to identify the sources of these structural changes. We build a multi-sectorial general equilibrium model with search frictions, endogenous layoffs, and occupational choices to estimate the relative impact of TBTC (Task-Biased Technological Change) and LMI changes (Labor Market Institutions) on employment patterns. Our analysis suggests that job polarization is mainly driven by TBTC in the US, whereas LMI changes drive job polarization in France.
