Female labour force intermittency and current earnings: switching regression model with unknown sample selection

摘要

Using the Health and Retirement Survey from the USA, this paper finds a 16% selectivity-corrected wage penalty among women who engage in intermittent labour market activity. This penalty is experienced at a low level of intermittent activity, but appears to not play an important role in a woman's decision to undertake such activity. In addition, employer preferences appear to play a larger role than human capital atrophy in the determination of the wage penalty.
