Impact of first birth career interruption on earnings: evidence from administrative data

This article makes use of unique administrative data to expand the understanding of the role women’s intermittency decisions play in the determination of her wages. We demonstrate that treating intermittency as exogenous significantly overstates its impact. The intermittency penalty also increases in the education level of the woman. The penalty for women with a high school degree with an average amount of intermittency during 6 years after giving birth to her first child is roughly half the penalty for college graduates. We also demonstrate the value of making use of an index to capture multiple dimension of the intermittency experience, and illustrate the importance of firm dynamics in the determination of a woman’s wage.
