Welfare Effects of a Permanent Unconditional Cash Transfer: Maricá, Brazil (Balakrishnan et al., 2024)

Summary

"Welfare Effects of a Permanent Unconditional Cash Transfer Program: Evidence from Maricá, Brazil," by Sidhya Balakrishnan, Roberta Costa, Johannes Haushofer, and Fábio Waltenberg (NBER Working Paper 33089, 2024), evaluates the Renda Básica de Cidadania (RBC, "Citizen's Basic Income") in the Brazilian city of Maricá. The program is significant for the Georgist case because it is funded from oil royalties channeled through Maricá's municipal sovereign fund (Fundo Soberano de Maricá) — making it, alongside Alaska, one of the very few real-world resource-rent-funded per-capita dividends, and the largest basic income program in Latin America. The authors surveyed 5,182 individuals between September 2021 and April 2022 and used propensity-score matching with inverse-probability weights to build a matched comparison group.

Key Findings

• A permanent, unconditional resource-rent dividend. "The program is unique in that it is both unconditional and permanent, while existing programs typically only have one of these features." At the time of study it "made monthly household-level transfers of USD 180 PPP on average to about a fourth of the city's residents."
• Income and consumption gains. "Household income including transfers increased by 9%; consumption at the per capita level did not change significantly, but the household as a whole experienced a consumption increase of 5%."
• Suggestive child-outcome improvement. "We also observe improvements in an index of children's health and education, although the effect does not survive multiple inference correction and bounding."
• Labor displacement. "There was a notable displacement of other income sources, particularly labor income, which decreased by 17% among recipients, suggesting shifts to lower-paying but potentially more desirable jobs during the pandemic."

Relation to the Georgist Case

Maricá is the most important recent addition to the real-world evidence for rent dividends reducing poverty because it directly addresses that page's largest limitation — that "nearly all direct evidence comes from Alaska." Here is a second long-running, resource-rent-funded, unconditional per-capita dividend, in a large middle-income country rather than a small oil-rich US state, and it too raises recipients' incomes and consumption. The picture is honestly nuanced: the income gain (9%) partly reflects the transfer itself, per-capita consumption did not move significantly, the child-outcome effect does not survive correction, and labor income fell 17% (interpreted by the authors as a shift toward more desirable work during the pandemic, not disengagement). The authors call this "a nuanced picture of the socioeconomic benefits of unconditional cash transfers." It is quasi-experimental (matched comparison), not a randomized or synthetic-control design, so it is corroborating rather than definitive.

Bears On

• Benefit (supports): Rent dividends reduce poverty and inequality — a second real-world resource-rent dividend that raised household income and consumption.
• Benefit: Resource-rent dividends are workable and durable — Maricá's decade-plus, oil-fund-backed operation is a durability case beyond Alaska.
• Concept: Citizen's Dividend · Resource Rents.
