SSASIM Output Statistics Overview (2/17/16)

The benchmark runs in CBA mode and OLC mode automatically produce .asm, .ssa, .sti, and .sto SSASIM output files. All other SSASIM output files must be explicitly requested in a run specification file using SSASIM input parameters located in the OUTPUT table. And all of the four listed above (except for the .ssa output file) can be turned off in a run specification file. The benchmark runs in CBA mode also automatically produce five output files related to exemplary cohort individuals, which should be handled using the ECI Toolkit.

All SSASIM output files can be viewed and/or compared via the RSF Toolkit Analyze menu.

All SSASIM output files are listed below:


.ASM file contains average, post-transition values for fifteen key assumption variables for each scenario.

.AST file contains annual values of fifteen key assumption variables for one simulation scenario that is specified by the SSASIM OUTPUT.ast_sc input parameter.

.ASX file contains values of fifteen key assumption variables for each scenario in one simulation year that is specified by the SSASIM OUTPUT.asx_yr input parameter.

.BEN file contains numbers of beneficiaries for OASI and DI for each calendar year from RUN.year_zero on in each scenario, as well as AWI, CPI, and MTE-related parameters for each calendar year in each scenario.

.CAP file contains annual capital market statistics for one scenario that is specified by the SSASIM OUTPUT.cap_sc input parameter.

.CAX file contains extra capital market statistics for each scenario.

.COH file contains life-expectancy and low-benefit thresholds for cohort individuals born in COHORT.birth_year.
NOTE: this output file is not available in the OLC mode of model operation.

.C?? files contain social security money's worth statistics for exemplary cohort couples specified in the SSASIM INDS and IND tables using the ECI Toolkit.
NOTE: these output files are not available in the OLC mode of model operation.

.C?F/.C?M files contain social security money's worth statistics for exemplary cohort individuals specified in the SSASIM INDS and IND tables using the ECI Toolkit.
NOTE: these output files are not available in the OLC mode of model operation.

.CXH file contains identity of cohort individuals and couples, and the output file name containing results for each individual and couple, all of which information is used by the ECI Toolkit, which is the best way to work with exemplary cohort individuals and couples.
NOTE: this output file is not available in the OLC mode of model operation.

.EST file contains annual aggregate establishment (that is, economy-wide) statistics for each year of one scenario specified by the SSASIM OUTPUT.est_sc input parameter.

.MRD file contains values for age- and gender-specific mortality rates for each year of each scenario.
NOTE: this output file is not available in the OLC mode of model operation.

.OLC file contains aggregate values for each birth cohort at every age.
NOTE: this output file is available only in the OLC mode of model operation.

.PAY file contains values of payable-benefits percents for the OASI and DI program for each scenario year until the end of the actuarial test period. This output file is most often used to simulate payable (as opposed to scheduled) social security benefits. For details, see SSASIM input parameter documentation on RUN.paypctfile, OUTPUT.pay, and OUTPUT.pay_preyears.

.PFP file contains PIA formula parameters for each year of each scenario.

.POP file contains population statistics for each year of each scenario.

.SSA file contains program solvency statistics for OASI, DI, and OASDI trust funds for each scenario.

.STI file contains annual values of fifteen key assumption variables and three asset rates of return for each scenario year until the end of the actuarial period. See SSASIM input parameter documentation of TRND_MV table and the Operations section of the "Getting Started with the RSF Toolkit" for details on how to control the values of these assumption variables.

.STO file contains annual values for income rate, cost rate, and trust-fund ratio, for the combined OASDI program and for the OASI and DI programs separately, for each scenario year until the end of the actuarial period. And only when the SSASIM OUTPUT.sto_dollar input parameter is true, it also contains annual dollar income and cost amounts, plus taxable earnings and GDP in nominal dollars.

.TF? files (.TFC/.TFD/.TFR) contain annual values of OASDI/DI/OASI trust fund statistics for one scenario specified by the SSASIM OUTPUT.tfc_sc, OUTPUT.tfd_sc, and OUTPUT.tfr_sc input parameters.
