Results from rural Kenya are not necessarily applicable to high-income countries. However, there are nearly no similar randomized controlled trial findings of a long-term guaranteed income or a significantly large lump sum in countries like the U.S. While much more expensive in high-income countries, long-term income and large lump sum pilots should be tried and studied to learn if there are better ways to deliver cash that help people build wealth and escape poverty.
To add some more info:
Sample size was 295 Kenyan villages consisting of 73,511 individuals with a control group of 11,000.
Only individuals over 18 received payments. Individuals at least 15y.o. were told they would begin receiving payments once they turned 18.
Money was distributed via mobile cash transfer, to which 96% of Kenyans have access, and which doesn’t require a bank account
Payments averaged $0.75 per day at a time that maize consumption per capita was $0.60 per day.
The lump sum payment was equal to 2 years of monthly payments, reduced by 8%.
