Economic Impact of a Heritage Policy on Residential Property Values in a Historic District Context: The Case of the Old City of Quebec
Bibliographic record
Abstract
Previous studies have attempted to measure the willingness-to-pay to locate inside a historic district. Yet not enough attention has been paid to the implicit value attributed to the impact of heritage policies within the historic district. This paper fills that gap by investigating the impact of such policies on individual condominium properties for the case of the Old City of Quebec (Canada), designated by law as a protected area and included on the World Heritage List (UNESCO). More precisely, this research measures the impacts of the reorganization and landscaping of one particular street located south-west of the protection area in the old part of Quebec City. A difference-in-differences (DID) estimator based on a hedonic repeated sales approach is proposed to isolate such effects based on proximity to the site under study. Estimation results suggest that the reorganization of the street had no significant impact on the closest properties’ prices, but had negative effects for properties located within 150 to 450 meters of the street. These observations outline complex relations between heritage policies and urban landscaping projects.

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.
