Do Land Value Taxes Curb Land Prices? Capitalization, Speculation, and Spatial Inequality in Loja, Ecuador (Tubío-Sánchez & Reyes-Bueno, 2026)

Summary

"Do land value taxes curb land prices? Capitalization, speculation, and spatial inequality in Loja, Ecuador," by José María Tubío-Sánchez and Fabián Reyes-Bueno (both affiliated with PLANoSS, Universidad Técnica Particular de Loja), appeared in the Journal of Regional Science as an Early View article, published online 20 April 2026 (DOI 10.1111/jors.70063). The authors describe it as the first empirical Latin American analysis of land tax capitalization effects — a genuine gap the wiki's existing capitalization literature (drawn from Germany, Norway, and Taiwan) had not covered.

Method and Findings

Using 1,419 repeat land sales transactions in Loja, Ecuador, from 2010 to 2017, and combining instrumental-variable methods with spatial error models (SEM) and generalized additive models (GAM) to isolate the tax's causal effect on price, the paper finds that properties in the urban center see land prices fall by roughly 2.5% for each 1 percentage-point increase in the effective tax rate — direct evidence of tax capitalization at work. The effect is not uniform across the city: it decays by roughly 0.6 percentage points per additional kilometer from the city center, consistent with the theoretical prediction that capitalization should be strongest where land value (and thus the tax bill) is highest.

Two Complications

The paper does not stop at confirming capitalization; it complicates the policy story in two ways relevant to Georgist design debates:

• Capitalization does not automatically deliver affordability. Lower nominal land prices near the tax-heavy urban center do not necessarily make land more affordable to buy, because buyers still face the higher long-term tax obligation embedded in owning that land — capitalization shifts when the cost is paid (upfront, in a lower price) rather than eliminating it.
• Assessment quality determines who actually benefits. The authors document a pattern of systematic underassessment of rapidly appreciating areas, which shifts the effective tax burden toward slower-growth zones. This undermines both the tax's price-stabilizing intent and its equity case: the areas capturing the most unearned land-value gain are the ones paying proportionally less, while slower-growth (often lower-income) areas absorb more of the burden.

Relation to the Georgist Case

This is a clean, quantified confirmation of capitalization theory outside the high-income-country settings the wiki's existing evidence base (Germany, Norway, Taiwan) is drawn from — adding Ecuador, and Latin America generally, as a new geography. But the underassessment finding is the more important contribution for Georgist policy design: it is direct evidence that mass appraisal methods matter as much as the tax rate itself. A land value tax whose assessments lag behind actual appreciation in fast-growing areas does not merely lose revenue — it inverts part of the tax's intended distributional logic, understating the tax owed exactly where the unearned increment is largest.

Nuances and Limits

• Single mid-sized Ecuadorian city. Loja is not Ecuador's largest city; findings may not generalize to Quito or Guayaquil's substantially larger, more speculative land markets.
• No effect-size table beyond the urban-center estimate was available to this session — the ~2.5%/1pp and ~0.6%/km figures describe the urban-core gradient specifically; the paper likely reports fuller spatial coefficient tables not captured here.
• Abstract-level source (B-claim). This page is built from the Wiley abstract page and corroborating search results, not the paper's full body text or its underlying data.

Bears On

• Objection: Land Value Can't Be Assessed Accurately — direct empirical evidence that assessment quality, not just the tax's existence, determines whether an LVT achieves its price-stabilization and equity goals.
• Concept: Tax Capitalization — a new, non-OECD confirmation of the capitalization mechanism.
• Concept: Mass Appraisal Methods — the underassessment-of-fast-appreciating-areas finding is a concrete failure mode for assessment practice to guard against.
