Extractive Fiscal Governance and Subnational SDG Progress: Mining Canon Redistribution in Peru, 2012–2024 (Medrano-Sanchez & Mamani-Salinas, 2026)

Summary

"Extractive fiscal governance and subnational SDG progress: a systemic analysis of mining canon redistribution in Peru, 2012-2024," by Emilio J. Medrano-Sanchez (Universidad Tecnológica del Perú) and Alfredo Mamani-Salinas (University of Calgary), appeared in Frontiers in Political Science 8, published 2 July 2026. The paper is a rigorous 13-year fixed-effects panel study (23 regions × 2012–2024, 299 observations) testing whether Peru's mining canon — the constitutionally mandated redistribution of a share of mining-royalty and tax revenue back to the regions where extraction occurs — has reduced regional poverty, the policy's central justification.

Findings

The results complicate the simple "resource-rent redistribution reduces poverty" premise:

• No significant overall effect. Canon transfers show a negative but statistically insignificant association with regional poverty (β = −0.074, p = 0.530) across the full sample and period.
• Benefits concentrate roughly eightfold more strongly where mining is already intensive — the canon formula rewards regions by the scale of extraction occurring in them, not by measured need, so the transfer's (already-weak) poverty effect is disproportionately captured by already-mining-intensive regions rather than reaching poorer non-mining areas.
• Price-cycle dependence. Only the 2017–2019 moderate-commodity-price period shows a statistically significant poverty-reducing effect — the canon's usefulness as an anti-poverty tool appears to depend heavily on where global mineral prices sit in their cycle, not just on the transfer mechanism's design.
• A counterintuitive employment finding. Formal mining employment correlates positively with local poverty (β = +0.930, p = 0.070) — consistent with an extractive-enclave pattern, where mining jobs coexist with, rather than resolve, surrounding regional poverty, possibly because mining employment is capital-intensive and geographically concentrated relative to the wider regional population it is measured against.

The authors read this as evidence of a subnational resource curse: the mechanics of how extractive rent is redistributed — territorial equity, price-cycle stabilization, and the destination region's institutional capacity — matter as much as the fact that redistribution occurs at all, and recommend redistribution-formula reform, price- stabilization funds, and capacity investment.

Relation to the Georgist Case

This is a valuable, quantitatively rigorous complication of the wiki's resource rent capture works benefit claim: it does not contradict the Georgist case that resource rent should be captured for public benefit, but it demonstrates that capture alone is not sufficient — the design of redistribution (which formula, which level of government, with what price-cycle buffering) determines whether captured rent actually reaches the people it is meant to help. Read alongside Martinez's Colombia study (rent capture strengthens governance where institutions are minimally functional) and the Nasarawa State paper (misaligned rent-capture level weakens governance), Peru's mining canon supplies a third data point: rent is being captured and transferred here, by design, yet the transfer formula's territorial-equity failure means the policy still under-delivers on its own poverty-reduction goal.

Nuances and Limits

• Association, not identified causal effect. This is a fixed-effects panel regression, which controls for time-invariant regional differences but does not by itself rule out omitted time-varying confounders (e.g., unobserved regional development trajectories correlated with both mining intensity and poverty trends).
• The p=0.070 employment finding is only marginally significant at conventional thresholds (just above the standard 0.05 cutoff) — worth treating as suggestive rather than definitive.
• Peru-specific institutional and formula details. The canon's specific redistribution formula is a Peruvian policy design choice; the finding that this particular formula concentrates benefit in already-mining-intensive regions is not necessarily a general indictment of resource-rent redistribution as such, only of this design.

Bears On

• Benefit: Resource Rent Capture Works — where institutions are strong — a rigorous complication showing capture-plus-transfer is not sufficient; redistribution design and territorial equity matter independently.
• Research: Martinez: Colombia's Local Resource Rents — a contrasting Latin American subnational case.
• Research: Namo et al.: Nasarawa State Solid Minerals — a Nigerian case with the opposite structural problem (no local capture at all, rather than poorly-targeted capture).
