What we know about conditional cash transfers in LMICs
Progresa, Bolsa Família, BRAC graduation, and direct cash to the ultra-poor — what the strongest evidence base in development economics says.

Conditional and unconditional cash transfers in low- and middle-income countries are among the most carefully studied policy interventions of the last 30 years. Mexico's Progresa (1997) was designed from the start as a randomized rollout; the resulting body of evidence has shaped programs that now reach hundreds of millions of households across Latin America, Asia, and Africa.
The pattern is robust: well-targeted cash transfers — whether conditional or unconditional — increase school enrollment, reduce child labor, improve nutrition, and have small or no effects on adult labor supply. The strongest evidence is for transfers paired with health/education conditions (Progresa, Bolsa Família) and for graduation programs that bundle cash with productive assets, training, and savings (BRAC).
The implementation lesson is that targeting matters more than conditionality. Cash transferred to women, conditioned on observable health and education behaviors, has produced the largest documented gains.
Takeaway
In LMIC contexts, cash transfers — especially when bundled with assets or targeted at women — produce some of the most reliably positive effects in the development literature.

Positive findings
4 experiments- Positive
GiveDirectly — Large-Scale Basic Income in Rural Kenya
GiveDirectly / Princeton / MIT / UC Berkeley · Siaya County, Kenya · 2016
Effect: Consumption: +30% vs. baseline; assets: +40% in asset values; food security: significantly improved; psychological wellbeing: large positive effects on stress and happiness; hours worked: no reduction; local economic spillovers: significant — control villages within treated areas also showed consumption increases (~$2.50 for every $1 transferred, via multiplier effects)
- Positive

Effect: Child school enrollment: +4 pp; vaccination: +3 pp; household food consumption: +16% for extreme poor; poverty headcount: contributed to 29% reduction in extreme poverty 2002–2011 (program component)
- Positive
BRAC Graduation Programme
BRAC / MIT / multiple governments · Bangladesh (original); replicated in 10 countries · 2007
