Abstract
Abstract Considerable research focuses on why internal migration rates are declining across most of the Western world. Several studies also look at why people are less likely to change jobs than they were in the past. In this paper, we look at the prospect of declining economic returns as an explanation for the joint decline in both phenomena in Canada. We use the Canadian Employer‐Employee Dynamics Database, a linked job–individual–family–firm data set, to look at the 5‐year income trajectories for Canadian workers who changed job and province of residence (movers) in 1997, 2002, and 2007. We compare these returns with those of job switchers who did not move (nonmover job switchers) and with those that changed neither jobs nor province (nonmover nonjob switchers). We find that the mover's premium, defined as the increase in income that accompanies either a job change or a geographical move, has decreased over time and argue that this may help explain why internal migration and labour fluidity have been declining.

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
