The Post-childbirth Employment of Canadian Mothers and the Earnings Trajectories of Their Continuously Employed Counterparts, 1983 to 2004
Bibliographic record
Abstract
Using the 1983-to-2004 Longitudinal Worker File, this study examines the post-childbirth employment, job mobility and earnings trajectories of Canadian mothers. We found that both the long- and the short-term post-childbirth employment rates of early 2000s cohorts of Canadian mothers were higher than their mid-1980s counterparts, and, relative to childless women, Canadian mothers became less likely to quit over time. Our data also allow us to examine the earnings impact of childbirth for a group of Canadian mothers who had strong labour market attachment. For them, earnings dropped by 40% and 30% in the year of childbirth and the year after, respectively. Under both the fixed-effects and the fixed-trend models, the earnings impact of childbirth declined over the other post-childbirth years. Results from the fixed-trend model further suggest that, from the second to the seventh post-childbirth years, the negative effects varied between 8% and 3% and became negligible thereafter.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
