We provide empirical evidence from India's PMJDY program, a “big bang” supply shock that gives bank accounts to virtually all of its 280 million unbanked. Proprietary data from individual bank account statements shows that there is significant uptake, usage, usage growth, and balance...

We study theoretically and empirically the demand for microcredit under different liability arrangements and risk environments. A theoretical model shows that the demand for joint-liability loans can exceed that for individual-liability loans when risk-averse borrowers value their long-term...

Using data from a randomized controlled trial in 300 public high schools in Peru, this paper studies the potential of school-based financial education programs for youth. The intervention improves students' and teachers' financial knowledge by 0.14 SD and 0.32 SD, respectively. The impact of the...

We investigate whether trust in different financial institutions influences the choice of saving instruments. Is trust a significant determinant of household saving behavior? How does trust in different financial institutions affect the composition of household savings? Using unique survey data...

Although one of the primary objectives of microfinance has been the reduction of poverty through the provision of credit for income-generating purposes, evidence of its impact on poverty has been mixed. Even if there is no direct impact of microfinance, there may be an indirect positive impact...

Digital loans are a source of fast, short-term credit for millions of people. While digital credit broadens market access and reduces frictions, default rates are high. We study the role of the speed of delivery of digital loans on repayment. Our study uses unique administrative data from a...

We examine a randomized trial that allows separate identification of peer screening and enforcement of credit contracts. A South African microlender offered half its clients a bonus for referring a friend who repaid a loan. For the remaining clients, the bonus was conditional on loan approval....

This paper empirically examines the behavioral precautionary saving hypothesis by Koszegi and Rabin (2009) stating that uncertainty about future income triggers saving because of loss aversion. We extend their theoretical analysis to also consider the internal margin, i.e., the strength, of loss...

We experimentally test the impact of expanding access to basic bank accounts in Uganda, Malawi, and Chile. Over two years, 17%, 10%, and 3% of treatment individuals made five or more deposits, respectively. Average monthly deposits for them were at the 79th, 91st, and 96th percentiles of...

We examine the generalizability of internally valid estimates of causal effects in a fixed population over time when that population is subject to aggregate shocks. This temporal external validity is shown to depend upon the distribution of the aggregate shocks and the interaction between these...
