1# WP21 — Eligibility criteria (PRISMA 2020 adapted)23## Population / object4Residential property: single-family houses, condominiums/apartments, multifamily buildings, rental units, mixed residential5samples (recorded separately). Any country, 1970–2026.67## Inclusion (coefficient-based synthesis)8I1. Empirical study estimating a hedonic-type relationship between a residential price measure (transaction price, listing price,9appraised/assessed value, rent) and at least one identifiable property, neighbourhood, environmental, location, market or10AI-derived characteristic.11I2. Reports at least one coefficient (or marginal effect / implicit price) with a standard error, t-statistic, p-value or12confidence interval, or enough statistics to recover one transparently; reports the dependent-variable transformation and the13sample size.14I3. Peer-reviewed article, working paper, dissertation, book chapter or conference paper with a retrievable full text.15I4. Any language (translated screening).1617## Exclusion18E1. No residential price/rent outcome (commercial, land-only, agricultural, office).19E2. No property-characteristic regressors (pure time-series house-price models, macro studies, index construction only).20E3. Purely theoretical, methodological without an empirical application, or simulation-only.21E4. Only predictive-performance metrics without interpretable marginal effects → retained for the AI/predictive synthesis22(Section 9) but excluded from the coefficient synthesis.23E5. No standard errors or recoverable inference → retained for the descriptive/qualitative synthesis only (flag).24E6. Duplicate of an included study (same data, same models) → kept as a single study; versions linked.25E7. Full text not retrievable → recorded as "not retrieved" with reason.2627## Outcome families (never pooled across families)28Transaction price; listing price; appraised/assessed value; rent. Within a family, log and level dependent variables are29harmonised into effect-size families (percentage premium, elasticity, semi-elasticity, monetary marginal price, partial30correlation) per `protocol/preregistration.md` §4.3132## Screening33Stage 1 (title/abstract): rule-based scoring (keywords in `scripts/screening/keywords.yaml`) → candidates; LLM-assisted screening34by independent agents with a written reason for every decision; disagreements and "unclear" flagged for human review.35Stage 2 (full text): eligibility checklist I1–I4 / E1–E7 recorded per study in `data/metadata/screening_fulltext.csv`.36
