Group liability is often portrayed as the key innovation that led to the explosion of the microcredit movement, which grew with the Grameen Bank in the 1970s and continues on today with hundreds of institutions around the world. Group liability claims to improve repayment rates and lower...

We worked with two microlenders to test impacts of randomly assigned reminders for loan repayments in the "text messaging capital of the world". We do not find strong evidence that loss versus gain framing or messaging timing matter. Messages only robustly improve repayment when they include the...

The ex ante theory of collateral states that better informed lenders, such as informal lenders, rely less on collateral. We test this by contrasting the use of collateral between formal and informal lenders in the same market. Indeed, formal lenders rely more often on collateral, controlling for...

If the demand for credit by the poor changes little when interest rates increase, lenders can raise fees to cost-covering levels without losing customers. This claim is at the core of sustainable microfinance strategies that aim to provide banking services to the poor while eschewing long-term...

Auction mechanisms are widely recognized to improve allocation efficiency in various economic environments, but the literature on rotating savings and credit associations (ROSCAs) has yet to identify circumstances in which bidding ROSCAs achieve first-best allocations of funds. This paper...
