Several African countries have introduced state loan schemes. But governments have struggled to chase up debts. The private sector is now trying to do a better job. Kepler and Akilah, an all-female college in Kigali, are working with Chancen International, a German foundation, to try out a model of student financing popular among economists—Income Share Agreements. Chancen pays the upfront costs of a select group of students. Once they graduate, alumni pay Chancen a share of their monthly income, up to a maximum of 180% of the original loan. If they do not get a job, they pay nothing.
