Alexander Graham Bell would be astonished at the power of today’s smart phones. Yes, the app that makes it possible to find a Starbucks along an unfamiliar highway can feel like a miracle, but the true revolutionary power of the telephone is felt most in developing countries. In Kenya, for example, the mobile phone has, to some extent, stabilized the economy for many citizens and transformed quality of life.
Nearly all Kenyan households own at least one mobile phone—not state-of-the-art smart phones, but phones “smart” enough to accommodate at least one M-Pesa account. Available to any customer of Safaricom, Kenya’s mobile network leader, M-Pesa is a money transfer service that allows a daughter at one corner of the country to send money safely and securely to her mother in a village seven hours away. Previously, she would have entrusted an envelope of cash to a bus driver heading to her mother’s village (at considerable risk) or relied on a money transfer that took days—and a daunting amount of red tape—to process.
Of course, to withdraw funds through an M-Pesa account you must have access to an agent who can disperse the cash. Happily, in response to the popularity of M-Pesa, the network across Kenya has mushroomed to 150,000 agents. Working with Innovations for Poverty Action, Associate Professor of Applied Economics Tavneet Suri, a native Kenyan, and her colleague William Jack have been tracking incomes in regions where new agents have opened for business. They compared the financial health of those regions with that of regions where agents are not as accessible.
