Policy-induced Migration in Canada: An Empirical Study
Bibliographic record
Abstract
We investigate the influence of public policy on interregional migration in Canada using new \ninterprovincial migration data constructed from personal income tax files for the years 1974 to 1996. We consider the consequences for gross and net migration flows of regional variation in employment insurance, provincial social assistance, personal income taxes and public spending of different types, and we compare the effects of these policies to the impacts on migration of wages, employment prospects and moving costs. We also conduct a preliminary investigation of the migration consequences of certain extraordinary political events in Quebec and of the closing of the cod fishery in Newfoundland. Unemployment insurance is an especially important and well documented source of income for many people, and regional variation in the generosity of the insurance system over the last three decades has been substantial. The results suggest that while increasing the generosity of the system in high \nunemployment regions may have induced more migration to the Atlantic region than would otherwise have occurred, the resulting changes in gross flows are probably not large and have had, at most, small effects on average provincial unemployment rates. A variety of other interesting results is also provided.

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.
