Productivity Spillovers from Competitive Reallocation: Evidence from Canadian Manufacturing Plants
Bibliographic record
Abstract
This paper uses plant-level data on productivity growth and changes in market share over different periods during the 1970s, 1980s, and 1990s to investigate whether plants with declining market shares obtain productivity spillovers from more successful producers and whether the impact of spillovers is affected by the distance between plants. We are primarily interested in the extent to which productivity externalities moderate the centrifugal forces that separate growing plants from declining rivals because of the productivity advantages enjoyed by the former. The paper focuses on the productivity performance of plants with declining market shares as potential receivers of productivity spillovers. Two possible sources for these spillovers are examined rival plants operating at the technological frontier and rivals that are actively gaining market share. The analysis advances a model of the externality process in which the productivity of declining plants is influenced by (1) the economic distance of the declining plant from its technological frontier at the beginning of any period, (2) contemporaneous productivity gains in rival plants that are actively wresting market share away from decliners, and (3) the distance between rival plants. We evaluate the existence and magnitude of these sources of spillovers frontier plants and market-share gainers because of what they reveal about the types of productive information that struggling plants may be able to assimilate from rivals. Spillovers from the plants at the existing frontier are likely to reflect the established best practices of industry leaders; spillovers coming from market-share gainers involve new sources of productive knowledge that emerge as the frontier is actively being re-established. Our model also incorporates geographic information on the proximity of declining plants to both frontier plants and market-share gainers to test whether productivity spillovers are spatially circumscribed.

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.
