The authors developed and experimentally evaluated four novel educational programs delivered online: an informational brochure, a visual interactive tool, a written narrative, and a video narrative. The programs were designed to inform people about risk diversification an essential concept for financial decision-making. The effectiveness of these programs was evaluated using the American Life Panel. Participants were exposed to one of the programs, and then asked to answer questions measuring financial literacy—in particular, risk literacy—and self-efficacy. All of the programs were found to be effective at increasing self-efficacy, and several improved financial literacy, providing new evidence for the value of programs designed to improve financial decision-making.
