Project LMCM

LMCM: Labour Market Consequences of Motherhood is a joint project of researchers at ENSAE/CREST in France and IAB Nuremberg in Germany.

The project has two main goals:

  • – To prepare German and French registry labour market data for comparative research.
  • – To study the motherhood wage and employment penalty in France and Germany comparatively.

Using registry data for both countries will help us to better understand mechanisms underlying the different motherhood penalties in the two countries. We aim to study different factors contributing to the wage and employment penalty such as human capital depreciation, firm sorting, career trajectories, effects of norms and childcare in a comparative setup.

The project is funded via the ANR for the French group and the DFG for the German group.

PIs are Sander Wagner and Ivaylo Petev at CREST/ENSAE, France and Corinna Frodermann at IAB Nuremberg.
