That approach didn't wipe out poverty for participants, but they became "significantly less poor," said economist Dean Karlan of Yale University and the nonprofit Innovations for Poverty Action.
"There's no panacea," Karlan said, but the approach is "better than anything else I'm aware of."
Karlan and colleagues conducted an independent evaluation of the anti-poverty strategy, which is widely used in Bangladesh, to see if it would work in a variety of settings. Their review included more than 10,000 households in Ethiopia, Ghana, Honduras, India, Pakistan and Peru.
Key components of the programs include providing assets like livestock and training in how to manage them, a regular stipend to provide basic support, and encouragement to save money.
To evaluate the programme, the study randomly assigned eligible households to participate or not, and then compared the outcomes for the two groups over three years.
Most of the programme's activity was in the first few months. At the two-year mark, when the programme ended, the participating group was doing better across a wide range of measures.
