Financial development is critical for growth, but its micro-determinants are not well understood. We test leading theories of low demand for financial services in emerging markets, combining novel survey evidence from Indonesia and India with a field experiment. We find a strong correlation between financial literacy and behavior. However, a financial education program has modest effects, increasing demand for bank accounts only for those with low levels of education or financial literacy. In contrast, small subsidies greatly increase demand. A follow-up survey confirms these findings, demonstrating the newly opened accounts remain open and in use two years after the intervention.
