Lifetime PV measures for OASI program [.=r] and DI program [.=d]:
(monetary measures expressed in thousands of dollars)[PV=present-value]
(present values discounted to year in which cohort is 65 years old)
(present values expressed in COHORT.cpi_year dollars)
(present values calculated using Treasury bond yields as discount rates)
pvearn = PV of all earnings [PVE]
pvtax. = PV of payroll taxes and account contributions [PVT]
pvben. = PV of DB benefits & DC withdrawals & annuity payments [PVB]
> Note: two items NOT included in PVB are as follows:
(a) DC acct withdrawal used to buy an annuity
(b) DC acct balance at death
> Note: withdrawals & annuity payments are net of clawbacks & offsets
ratio. = payback ratio [PVB/PVT] in percentage terms
net\$.  = dollar net program PV [PVB-PVT]
net%.  = relative net program PV [(PVB-PVT)/PVE] in percentage terms
nirr%. = percentage discount rate that makes PVT equal PVB
rirr%. = percentage discount when PVT and PVB terms are in real \$

Note that these IRR statistics are calculated for each scenario
and then the scenario values of IRR are averaged to get a mean
just like all other statistics.  This differs from the IRR
statistic computed by others (e.g., Steuerle & Bakija, Retooling
Social Security for the 21st Century, Urban Institute, 1994) who
calculate one IRR for a single cashflow stream that has been
averaged over all the lifetime contingencies.  The two statistics
are not mathematically equivalent if the cashflow arrays contain
more than two time periods because of the nonlinearity introduced
by raising one plus the IRR to a power.  Examples suggest that
the IRR of the all-scenario average cashflows is somewhat higher
than the average of the scenario IRR values, creating an upward
bias in the estimate produced by the actuarial method.
On the other hand, the all-scenario mean of the other lifetime
present-value statistics computed here using the Monte Carlo
method are mathematically equivalent to those computed by others
(e.g., Steuerle & Bakija and Advisory Council Report) using
actuarial methods because the present-value function is linear
in the cashflows that are averaged in the actuarial method.
Unlike the Monte Carlo method, the actuarial method of computing
the mean present value provides no information about the
variability of the statistic across the different life histories
represented in the Monte Carlo scenarios.
