This study aims to draw on insights from behavioral economics to conduct a rigorous impact evaluation of alternative unconditional cash transfer designs in Kenya. The study's implementing partner, GiveDirectly, which provides unconditional cash transfers to poor households in rural Kenya, will be experimentally varying several features of these transfers. One area of focus will be the timing of transfers, where GiveDirectly will vary the structure and schedule of transfer payments, as well as recipients' control over these timing aspects. A second area of focus will be the role of social information and norms, varying the amount and kind of information recipients receive about assets purchased by their peers. This study will exploit the variation across these different designs to quantify impacts on 1) household-level socio-economic outcomes (income, assets, etc.), 2) measures of well-being (food security, intra-household discord/conflict, various psychosocial scales), and 3) recipients' decision-making process and cognitive ability.
