Some retirement plans allow the participant to choose how funds are invested. Having to direct investments may provide the participant with financial education. This paper finds that U.S. households covered by pension plans in which the employee chooses investments are significantly more apt to hold stock outside of their retirement plan than are households with pension plans offering no such choice. The effect of investment choice upon non-pension asset allocation is not explained by portfolio rebalancing or observable differences in income and saving preferences across households. This provides some evidence that the design of a pension plan may influence an employee's financial decisions outside of the pension plan, although unobserved heterogeneity in worker's preferences could also explain the result.
