Abstract
Economic impact studies have been an important component of the debate surrounding the merits of subsidizing professional sports teams. However, various studies have arrived at remarkably different conclusions about the size of a sports team’s economic impact on the region in which they are located. The purpose of this study is to determine the causes of the wide variance of economic impact estimates between different studies. A meta-analysis was used on the 13 studies to determine the causes of the differing impacts. Although some of the variance is due to understandable differences in the size of the geographical region and sports team in question, differing assumptions about whether the expenditure of locals should be included accounted for a substantial variance in the impact.

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.
