Marking Social Security's Open Group Liability to Market
by Paul Anton Koehler and Laurence J. Kotlikoff
WP 2009-217
|
- We find that the market value of Social Security’s open group liability may be many times larger than the $15.1 trillion stated in the Trustees’ 2009 Report.
- The open group liability refers to what it will cost to keep the system operating as is indefinitely.
- We treat the growth rates of benefits and contributions as returns from a hypothetical security.
- We achieve mixed results -- some show the unfunded liability to be much larger than the Trustees’ Report, while some scenarios feature positive numbers.
