 "exclusion_reason": "Repeat-sales difference-in-differences model (Tables 3-6): dependent variable is the change in log price between two sales of the same property; regressors are a time-bracket indicator (B) and its interactions with property type, rural/coastal location, flood-defence construction (B*D) and defence design variables. Property characteristics are differenced out and enter only as interactions; no hedonic price-level regression with characteristic coefficients. Flagged for human review: the flood-defence treatment effect (urban +12.6% to +16.7%, rural -0.8% to -5.0%) is an environmental (flood_risk) effect but not a hedonic coefficient.",
