Kenya
GiveDirectly, a US-based nonprofit, runs the world's largest and longest-running universal basic income study in rural Kenya, launched in 2017-2018. Roughly 23,000 adults across 195 villages in Siaya and Bomet Counties receive unconditional cash via mobile money (M-PESA), split across a 12-year monthly UBI arm, a 2-year monthly UBI arm, and a one-time lump-sum arm, compared against 100 control villages. The $30M initiative is funded by philanthropic donors and independently researched by economists from MIT, UCSD, and Princeton with Innovations for Poverty Action (IPA). Early 2023 results found long-term UBI encouraged saving and investment while lump sums drove more business creation, with no evidence of reduced work effort in any arm.
