A recent literature argues that a ‘motherhood penalty’ is a main contributor to the persistent gender wage gap in the upper part of the earnings distribution. Using Norwegian registry data, this column studies the effect of parenthood on the careers of high-achieving women relative to high-achieving men in a set of high-earning professions. It finds that the child earnings penalty is substantially larger for mothers with an MBA or law degree than for mothers with a STEM or medical degree.

Labour mobility is an important prerequisite for the efficiency of labour markets. In the EU, however, different standards across countries present an implicit economic barrier for high-skilled professionals. This column examines how the recent EU harmonisation of professional standards in accounting affected cross-border migration relative to other professionals. The harmonisation had a strong positive effect on accountants’ cross-border migration. Harmonisation could thus be a potentially powerful tool for policymakers seeking to improve labour market efficiency.
