Microcredit is an innovative financial tool designed to reduce poverty and fix credit market imperfections. We use experimental measures of time discounting and risk aversion for villagers in south India to highlight behavioral features of microcredit. Conditional on borrowing from any source, women with present-biased preferences are more likely than others to borrow through microcredit institutions. Microcredit contracts require loan repayments in regular, fixed installments and they harness peer pressure to encourage discipline. These innovations mirror mechanisms highlighted in behavioral approaches to saving, suggesting that microcredit's popularity stems partly from modes of encouragement and self-discipline absent in typical lending mechanisms.
