The phenomenal success of Kenya’s M-PESA system, which allows people to store and transfer funds via electronic accounts that they access via mobile phones, has raised hopes that mobile money may provide a way for the poor to access basic banking services. In an earlier post, I presented findings from my recent working paper with Aaron Thegeya, showing that a remarkable 73% of Kenyan adults use mobile money, and nearly a quarter use it every day.
We also show that savings with a simple M-PESA account is common, with 2/3 of M-PESA users reporting that they save in some form with M-PESA. We see some mild evidence that M-PESA may increase savings: controlling for various characteristics, those who are registered for M-PESA are 32 percent more likely to report some savings activity.
Why do people save with M-PESA when it doesn’t pay interest? A possible explanation comes from an experimental study on health savings (not involving M-PESA).
