What Are the Costs and Benefits of Social Security Investing in Equities?
Some observers believe that investing a portion of the Social Security Trust Fund in equities would strengthen its finances and improve the program’s intergenerational risk-sharing. However, equity investments would also expose the program to greater financial risk and potentially greater political risk. Monte-Carlo simulation methods are used to investigate whether equity investments would likely strengthen the long-term outlook of the Trust Fund relative to the current policy of investing 100 percent of reserves in U.S. government bonds. The issues surrounding equity investments also go beyond expected returns on the Trust Fund portfolio. Concerns of government interference with the allocation of capital in the economy and with corporate decision-making as well as the accounting treatment of equity investments are also discussed.
