_Development Report_ (GFDR) identifies financial education as the leading response to the question “What is the most effective policy to improve access to finance among low-income borrowers?” (See Figure 1.) What still remains to be proven is whether this faith in financial education is substantiated by evidence of impact. Are there approaches to teaching financial skills or modifying financial behaviors through educational programs, training, or other outreach activities which have reliable, positive results? The objective of this paper is to analyze the evidence of impact for financial literacy and capability interventions through a systematic review of the evidence. The review includes the use of meta-analysis, a statistical technique that pools data from different studies to test for significance in the enlarged sample of observations this creates. This paper is also different from most previous narrative reviews in focusing exclusively on research that analyzes the impact of financial education interventions. Key characteristics of 188 papers are coded to create a rich data set with the characteristics of the interventions as well as statistical information on the impact of programs on outcome variables such as general savings, retirement savings, and credit performance. This data set is then used for a descriptive analysis of the literature and for empirical tests using meta-analysis.

More than 140 of the 188 studies identified through this review indicate that financial education can be helpful in improving financial outcomes, although it is important to note that most of these employ nonrigorous empirical methods and may suffer from selection bias or other econometric concerns. Some of the more recent studies employ rigorous analytical tools such as randomized control trials (RCTs), and the impacts reported across these papers are more reliable. Examples of positive impacts come from Cai et al. (2013) who find that financial education sessions for rural farmers increase take-up rates for insurance in China. In South Africa, financial messages delivered through a popular soap opera are shown to improve desirable financial behaviors such as borrowing from formal financial institutions rather than from higher cost options such as retailers (Berg and Zia, 2013). In India, Sarr et al. (2012) find that financial education increases the use of a no-frills savings account even months after the intervention ended. In the U.S. a non-RCT study of the Money Smart financial education curriculum by the FDIC (2007) finds that participants are more likely to open deposit accounts, save money, and adhere to a budget.

However, our review of the literature also finds numerous papers (approximately 40 in our sample) citing either no impact or only a modest impact from the intervention which, may not justify the cost of financial education. Cole et al. (2011) for example, find that a financial education intervention among unbanked consumers in Indonesia is less effective at stimulating savings accounts than a small monetary incentive. Likewise, results from a media intervention in Kenya that included comics with financial literacy messages find no significant impact on key variables including savings rates (Eissa et al., 2013). In the U.S., Cole et al. (2013) evaluate mandated personal finance courses in high schools and find that they have no effect on financial outcomes, while training in mathematics is shown to benefit students through greater levels of financial market participation, more investment income, and better management of debt. Similarly, Hung and Yoong (2010) study retirement savings behaviors of adult populations in the U.S. and find that unsolicited financial advice has no impact on savings and investment decisions.
