Abstract
While maternal employment has become the norm in advanced industrial nations, gendered norms of parenting and employment disadvantage mothers in the labor force. This paper sheds new light on motherhood pay gaps by investigating the contribution of an understudied dynamic—mothers’ overrepresentation in low-paying workplaces. Estimating between- and within-establishment wage gaps with nationally representative Canadian linked employer-employee data reveals that segregation in low-paying establishments accounts for the bulk of mothers’ wage disadvantage relative to childless women. Pay gaps net of human capital differences are not chiefly a result of mothers’ lower wages vis-à-vis similar women in a given workplace, but rather stem from the fact that mothers are disproportionately employed in workplaces that pay all employees relatively poorly. Having identified the importance of between-establishment segregation, additional analyses probe support for two theories about underlying mechanisms: compensating differentials tied to family-supportive work contexts, and discrimination. While each plays a role, evidence is strongest for discrimination, with organizational characteristics that tend to reduce opportunities for discrimination also dramatically reducing or eliminating motherhood pay gaps.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
