The Heterogeneous Effects of Trade across Occupations with Sergi Basco, Maxime Liegey &  Marti Mestieri

  Conditionally accepted  at The Journal of International Economics

This paper develops and implements a novel test of the Stolper-Samuelson theorem. We use nationally-representative matched employer-employee panel data from 1997 through 2015 to study the effect of the rise in China's exports on French worker earnings. Our version of the Stolper-Samuelson theorem states that there is a negative correlation between occupation exposure to Chinese competition and change in worker earnings. First, we document substantial heterogeneity in trade adjustment across occupations. Then, consistent with the Stolper-Samuelson prediction, we show that workers initially employed in occupations more intensively used in hard-hit industries experience larger declines in earnings. We also show that workers tend to move out of hard-hit industries, but they tend to remain in their initial occupation.

Gravity beyond CES: Implications for Substitution Patterns and Welfare  with Paul Piveteau 

 Reject&Resubmit at Restat

Gravity models of international trade often rely on preferences with constant elasticity of substitution (CES) across varieties. This assumption rules out any role for product differentiation in export performance and imposes homogenous effects of competition across countries. In this paper, we augment standard gravity equations with structural controls for an exporting country’s isolation in the product space. The augmented equation can be estimated easily by 2SLS. We show that our correction improves the predictions of gravity models by capturing stronger substitutions between similar exporters.
