Vox's Dylan Matthews reports on a large-scale IPA study in partnership with GiveDirectly on the impact of universal basic income in Kenya. Universal basic income (UBI) is a specific type of cash transfer—long term, sized to be sufficient for basic needs, and given to all members of a society, making this type of research potentially more scaleable. Matthews highlights some of the results so far: while the group who received a larger lump sum did better overall than the group that received monthly payments, long-term monthly payments also had the advantage of providing greater flexibility and less pressure on investment options.
