Measuring Land Value Increments from Public Action: The Case of the Detroit Auction Program (Ortiz Beleño, Alvayay Torrejón & Paredes, 2026)

Summary

"Measuring Land Value Increments from Public Action: The Case of the Detroit Auction Program," by Pabel Ortiz Beleño, Camila Alvayay Torrejón, and Dusan Paredes, is a Lincoln Institute of Land Policy Working Paper (August 2026). It studies whether Detroit's Land Bank Authority's post-2014 program of auctioning vacant, foreclosed homes to buyers who commit to rehabilitation measurably raised nearby land values — a direct empirical test of the mechanism the wiki's public investment capitalizes into land page documents for infrastructure spending, applied here to public land disposition instead.

Method and Findings

Using a synthetic control methodology comparing auctioned-parcel neighborhoods against matched counterfactual areas, the paper finds the auction program positively affected neighboring property prices on average. But the effect is not uniform: the authors document spatially heterogeneous effects, including significant price declines in certain treated neighborhoods — some areas saw the expected uplift from reduced blight and reactivated vacant properties, while others saw prices fall despite the same program design.

Relation to the Georgist Case

This is directly relevant evidence for the wiki's land banking and speculative vacancy coverage: it confirms the basic mechanism Georgists expect — clearing blight and returning vacant land to productive use raises nearby land values — while also cautioning that the effect is not automatic or uniform. A program identical in design can raise values in one neighborhood and depress them in another, depending on local conditions the average treatment effect alone would obscure — a useful complement to the wiki's existing public-investment-capitalizes-into-land literature, most of which documents infrastructure investment rather than land-disposition programs specifically.

Nuances and Limits

• A single US city's specific program design. Detroit's Land Bank Authority program has particular features (auction-plus-rehab-commitment structure, the scale of Detroit's vacant-property stock) that may not generalize to other cities' vacant-land programs.
• The public summary does not report specific magnitude figures or name which neighborhoods saw declines — those details live in the full 51-page working paper body, not independently extracted for this page.
• Full landing-page content read directly, not the complete paper body (B-claim). The paper's own working-paper page (not paywalled) was read directly for its methodology and headline findings, but the full PDF's detailed results tables were not extracted.

Bears On

• Concept: Land Banking — direct empirical evidence on whether a public land-disposition program raises neighboring values, with an honest caveat about spatial unevenness.
• Concept: Speculative Vacancy — the underlying blight/vacancy-clearing mechanism this program targets.
• Problem: Public Investment Capitalizes Into Land — extends the capitalization evidence base from infrastructure spending to land-disposition programs specifically.
