2019-06 Precautionary savings and shock-coping behaviors

For the vulnerable, even small shocks can have significant short- and long-term impacts. Beneficial shock-coping mechanisms are not widely available in sub-Saharan Africa. We test whether individual precautionary savings can reduce a shock-coping behavior common in SSA that has negative spillovers: transactional sex. Among a set of vulnerable women, we randomly assigned an intervention that promoted savings in a mobile banking account labeled for goals and emergency expenses. We find that the intervention led to an increase in total mobile savings, reductions in transactional sex as a risk-coping response, and a decrease in symptoms of sexually transmitted infections. Changes are sustained in the medium-term.
