If you ask someone in the international development field what technology has improved foreign aid the most in the last 50 years, you’d probably hear that its been the cell phone. Even in places with dilapidated schools, poor governments, and little infrastructure, cell service can be strong and more and more rural populations own and use the little devices.
Cell phones allow rural farmers and craftsmen to connect to international markets which helps them receive a better price for their product. They have opened up the world of banking to millions of people with no local branch. Now, they’re being used for direct cash transfers from international development organizations in times of crisis.
Within the field, the idea of direct cash transfers is hotly debated. The basic idea goes, what poor people need are resources and so the more constraints you put on those resources (it has to be used for seeds, education, housing) the less effective they are. But cash transfers have huge hurdles that need to be overcome. Its costly in terms of the labor required to literally hand out money to individuals. To reduce the cost on the organization they often hand out money in centralized villages, which make it costly for villagers to access the money because they often need to travel for it.
A new research paper looks at how effective it might be for an NGO to give direct transfers via cell phone. They studied the efforts of Concern Worldwide, which offered unconditional, direct cash transfers to approximately 10,000 households in Niger following a drought in 2009-2010.
Instead of following the traditional method of direct cash transfer, they tried a randomized experiment. In 1/3 of targeted villages participants received monthly cash transfers through a mobile program called Zap; in 1/3 they received manual cash transfers, and in 1/3 manual cash transfers plus a cell phone.
Beyond just the ease of the Zap transfers they found that recipients of the mobile transfer actually used the money slightly differently. From the abstract:
“We show that the zap delivery mechanism strongly reduced the variable distribution costs for the implementing agency, as well as program recipients’ costs of obtaining the cash transfer. The zap approach also resulted in additional benefits: households in zap villages used their cash transfer to purchase a more diverse set of goods, had higher diet diversity, depleted fewer assets and grew more types of crops, especially marginal cash crops grown by women. We posit that the potential mechanisms underlying these results are the lower costs and greater privacy of the receiving the cash transfer via the zap mechanism, as well as changes in intra-household decision-making. This suggests that m-transfers could be a cost-effective means of providing cash transfers for remote rural populations, especially those with limited road and financial infrastructure.”
It is unclear why exactly, the recipients of the Zap transfer used the money differently but this is an exciting advancement in international development.
Thanks to Freakonomics for turning me on to the paper.
