Financial literacy programs are popular, despite limited evidence that they lead to significant changes in savings behavior. We experimentally test the impact of financial literacy training on clients of a branchless banking program that offers doorstep access to banking to low income households. The intervention had significant impacts: total savings in the treatment group increased by 49% ($39) within a period of one year. The increase in savings is due in part to decreases in expenditures on temptation goods. These results suggest that financial education interventions can be successful in changing savings outcomes, though we are only able to speculate why the program worked in this context. 1 Acknowledgements: We thank FINO PayTech for implementing this program and Prakash Lal of FINO PayTech for his support.

Mass media and social marketing programs are cheap, scalable, and potentially effective means of influencing consumers' financial behavior and decisions. In light of this potential, and in order to provide clear policy direction, this paper provides an overview of the existing and ongoing research efforts in this domain, and highlights the importance of expanding the evidence base by conducting rigorous impact assessments in this field. Exploring four case studies, it provides lessons in designing effective evaluations specifically targeting mass media and social marketing programs on consumer financial management, highlights the value of incorporating insights from behavioral psychology in program design, and suggests avenues for future research.
