Because earnings data are much more limited than for the previous outcomes, the estimations here apply to a sample of 10 countries and for a limited period of time. The estimates obtained with the piecewise linear regression show large standard errors and for this reason do not provide more information than the model estimated in Columns 2 and 3. Although not all these later estimations find statistically significant associations with the average earnings of women and men, they do show a significant negative effect on the earnings gap between men and women working full-time.
