This study provides experimental evidence about the barriers to adoption of formal savings in Africa. In collaboration with a large commercial bank, I conduct an experiment designed to measure the relative importance of convenience and information on the adoption of formal savings. When individuals can open an account at their place of business they are much more likely to open an account. Novel information about the benefits of savings has a slight but insignificant negative effect on account opening. While over half (55%) of individuals report an interest in opening an account when initially approached, only 2% of individuals are using the accounts 2 months later. I explore several potential explanations between individuals’ selfreports of interest in the accounts and their later behavior. I argue that individuals’ behavior in the experiment is consistent with social pressure to conform to the encouragement to open an account and some projection bias in predicting their future behavior. The results illustrate that for individuals struggling to save, encouraging enrollment in formal finance may be less effective than tools which help individuals follow-through with self-reported savings intentions.

Standard models of investment predict that credit-constrained firms should grow rapidly when given additional capital, and that how this capital is provided should not affect decisions to invest in the business or consume the capital. We randomly gave cash and in kind grants to male- and female-owned microenterprises in urban Ghana. Our findings cast doubt on the ability of capital alone to stimulate the growth of female microenterprises. First, while the average treatment effects of the in-kind grants are large and positive for both males and females, the gain in profits is almost zero for women with initial profits below the median, suggesting that capital alone is not enough to grow subsistence enterprises owned by women. Second, for women we strongly reject equality of the cash and in-kind grants; only in-kind grants lead to growth in business profits. The results for men also suggest a lower impact of cash, but differences between cash and in kind grants are less robust. The difference in the effects of cash and in-kind grants is associated more with a lack of self-control than with external pressure. As a result, the manner in which funding is provided affects microenterprise growth.

Farmers face a particular set of risks that complicate the decision to borrow. We use a randomized experiment to investigate (1) the role of crop-price risk in reducing demand for credit among farmers and (2) how risk mitigation changes farmers’ investment decisions. In Ghana, we offer farmers loans with an indemnity component that forgives 50 percent of the loan if crop prices drop below a threshold price. A control group is offered a standard loan product at the same interest rate. Loan uptake is high among all farmers and the indemnity component has little impact on uptake or other outcomes of interest.
