The effects of using mobile money in delivering a cash transfer program in Niger is studied. In response to a devastating drought, targeted households in 96 villages received a monthly unconditional cash transfer, with women as the primary beneficiary. The delivery channel provided the cash transfer in hand as well as electronically, whereby program recipients received the transfer via the m-transfer system, as well as m-transfer-enabled mobile phone. The households in the m-transfer group used their cash transfer to buy more diverse types of goods and were more likely to purchase protein and energy-rich foods. These diverse uses of the transfer also resulted in a 9%-16% improvement in diet diversity, primarily due to increased consumption of beans and fats, and children consumed an additional one-third of a meal per day. M-transfer program recipients traveled shorter distances to obtain their transfer as compared with their manual cash counterparts. Program recipients, all of whom were women, reported that the m-transfer was less observable to other household members, thereby allowing them to temporarily conceal the arrival of the transfer.
