Money-back guarantees in individual retirement accounts: Are they good policy?

Abstract

Embedding mandatory investment guarantees in individual retirement accounts (IRAs) can protect workers from equity market shortfalls, but policymakers must understand the economic costs of such guarantees as well as their incidence. Using a life cycle model calibrated for Germany, where investors have access to stocks, bonds, and tax-qualified IRAs, we show that abandoning the guarantee could enhance old-age consumption for over 75% of retirees without harming pre-retirement consumption. Investors averse to equity losses accumulate only moderately more in guaranteed accounts, as these offer only limited protection against market crashes.
