"[The authors] show that people whose only exposure to investment decisions is by virtue of their participation in an employer-sponsored 401(k) plan ... suffer from higher levels of financial illiteracy than other investors. This lack of financial literacy is critical both because of the financial consequences of poor financial decisions and because of a legal structure that relies on participant choice to limit the fiduciary obligations of the employer with respect to the structure and options provided by the retirement plan.... [The authors] propose mandated employer-provided financial education ... [and] identify and discuss three requirements that a financial education program should incorporate."
