Access for Appraisal: A Systematic Review of Estimating Transport Benefits via Real-Estate Uplift

The paper by Mann and Levinson (2026) argues that real‑estate value uplift can serve as a robust alternative to travel‑time savings in transport cost‑benefit analysis. A systematic review identified fourteen empirical studies, most of which apply difference‑in‑differences for ex‑post appraisal, while ex‑ante applications rely on cross‑sectional hedonic models with limited endogeneity control. Findings show uplift estimates often surpass direct user benefits, yet current approaches neglect supply‑side reactions, externalities, and model validity. The authors propose a research agenda that integrates benefit‑transfer techniques, land‑use dynamics, and stronger causal methods to legitimize real‑estate‑based appraisal.
