The wages of motherhood: better or worse?

Data from two British cohort studies show that women with children have low er wages than childless women. We develop an innovative decomposition of th is 'family gap'. The crude pay gap between mothers and childless women in t heir thirties was similar in 1978 and 1991, but low pay in part-time work b ecame more important in explaining this gap, and human capital less so. We find that, among full-time employees, women who broke their employment at c hildbirth were subsequently paid less than childless women. In contrast, mo thers who maintained employment continuity were as well paid as childless w omen, but neither were as well remunerated as men. JEL classification: J13, J16.
