The evolution of financial literacy over time and its predictive power for financial outcomes: evidence from longitudinal data

Abstract

We administered the FINRA Foundation's National Financial Capability Study questionnaire to members of the RAND American Life Panel in 2012 and 2018. Using this unique, longitudinal data set, we investigate the evolution of financial literacy over time and shed light on the effect of financial knowledge on financial outcomes. Over a six-year observation period, financial literacy appears to be rather stable, with a slight tendency to decline at older ages. Importantly, financial literacy has significant predictive power for future financial outcomes, even after controlling for baseline outcomes and a wide set of demographics and individual characteristics that influence financial decision making.
