In Country' Groups 2, 3 and 4, the characteristics of the partner share little or no association with the probability of an employed mother working full-time. In Country Group 2, there is a negative significant association between an employed mother having a high-earning partner and the likelihood of the mother working part-time, but the marginal effect is only small. Employed mothers with a high-earning partner are only about 2 percentage points less likely to work full-time than otherw'ise similar mothers with a low-earning partner. Otherwise, the partner’s characteristics appear to have no effect on the probability of full-time work.
