The proliferation of new financial products and services continues to outpace the capacity of individuals and families to make informed financial choices. Financial education geared toward adults has shown low uptake, so the focus has shifted to introducing financial literacy during the schooling years. This research looks at a comprehensive financial education program spanning six states, 868 schools, and approximately 20,000 high school students in Brazil through a randomized control trial. The program increased student financial knowledge by a quarter of a standard deviation and led to a 1.4 percentage point increase in saving for purchases, better likelihood of financial planning, and greater participation in household financial decisions. “Trickle-up” impacts showed improvements in parental financial knowledge, savings, and spending behavior. The evidence suggests the program affected students’ preferences and attitudes about financial decisions well beyond the schooling years. Read the entire paper here.
