SSASIM input table DIBEN

Contains specification of dynamic policy parameters used in calculation of DI benefits.

Parent table is: POLICY

There are no child tables.

Go to SSASIM input parameters overview

SSASIM:   DIBEN . id
Identifies set of DI benefit policy parameters specified on this row of table, so id value should be unique for each group of rows that has a collection of cal_year values (see below).

Valid values: 1 to 999999999 (nine digits), Integer

Source code: policy.h and policy.cpp

SSASIM:   DIBEN . notes
Describes specification of table row in free-form note.

Valid values: any ASCII text (Note: do not copy and paste from a word processor because of the possibility of embedded non-ASCII characters.)

Source code: notes are not read by the model

SSASIM:   DIBEN . cal_year
Identifies calendar year during which the DI benefit policy parameters specified on this table row are in effect. Calendar years for which no row exists have their parameter values calculated by linear interpolation between the closest prior year and closest subsequent year for which table rows have been specified for this id. Values for years following the last specified year are taken to be equal to values in the last specified year.

Valid values: 1992 to (1992+RUN.num_years), Integer

Source code: policy.h and policy.cpp

SSASIM:   DIBEN . lastkidage
Specifies maximum age of disability onset for a child to be considered a disabled adult child beneficiary.

Valid values: 0 to 99, Integer

Source code: policy.h and policy.cpp for reading the parameter from the input database and oasdiben.cpp for using the parameter in DI benefit computations.

SSASIM:   DIBEN . iben_pia_f
Specifies percentage (not decimal) fraction of disabled worker's PIA that is paid to disabled worker as a benefit.

Valid values: 0.0 to 100.0, Real

Source code: policy.h and policy.cpp for reading the parameter from the input database and oasdiben.cpp for using the parameter in DI benefit computations.

SSASIM:   DIBEN . sben_pia_f
Specifies percentage (not decimal) fraction of disabled worker's PIA that is paid to spouse of disabled worker as a benefit (before application of maximum family benefit rules for disability benefits).

Valid values: 0.0 to 100.0, Real

Source code: policy.h and policy.cpp for reading the parameter from the input database and oasdiben.cpp for using the parameter in DI benefit computations.

SSASIM:   DIBEN . kben_pia_f
Specifies percentage (not decimal) fraction of disabled worker's PIA that is paid to each kid of disabled worker as a benefit (before application of maximum family benefit rules for disability benefits).

Valid values: 0.0 to 100.0, Real

Source code: policy.h and policy.cpp for reading the parameter from the input database and oasdiben.cpp for using the parameter in DI benefit computations.

SSASIM:   DIBEN . cabr_a_pct
Specifies convert-age benefit-reduction avoidance percent per year of disability. This policy parameter is relevant in two cases: (a) when the PIA formula fractions for the disability event produce a higher PIA than if the PIA formula fractions for a non-disability event were applied to the same AIME, as in the Kolbe-Stenholm proposal, and (b) when the OAI PIA is lower than the DI PIA at convert age, as in the Graham proposal.

In either case, the micro model will reduce the benefit at the NRA (when DI-to-OAI conversion takes place) with the amount of the benefit reduction depending on the number of years of disability. IMPORTANT NOTE: read the DIBEN.ks_br_type documentation below to see how to specify which benefit-reduction (or benefit-blending) type is used at the DI-conversion age.

This parameter is an avoidance percentage, which means that if it is zero there is no avoiding the benefit reduction at DI conversion. A value of 100 means the benefit reduction is avoided completely. A value of 2.5 means that forty years of disability are required for complete avoidance and that ten years of disability causes a benefit reduction at conversion that is 75 percent of the difference between the disability-event PIA and the retirement-event PIA.

Valid values: 0.0 to 100.0, Real

Source code: policy.h and policy.cpp for reading the parameter from the input database and oasdi.cpp for using the parameter in DI benefit computations.

SSASIM:   DIBEN . oabr_pct
Specifies DI-onset-age benefit-reduction percent for each year between DI-onset and age 22. This is not an avoidance percent. This policy parameter is relevant when two things are true: (a) the PIA formula fractions for the disability event produce a higher PIA than if the PIA formula fractions for the retirement event were applied to the same AIME, and (b) the policy regime calls for the reduction in the DI PIA to be made at the DI-onset age (rather than at the DI-conversion age).

In such a case, the micro model will reduce the PIA at DI-onset age down toward the OAI PIA by a percent that equals the product of the oabr_pct parameter and (DI_onset_age-22). So, for example, if oabr_pct is zero, there is no reduction in the DI PIA at any DI-onset age (which is the appropriate setting if the DI PIA reduction is being done at DI-conversion age as in the Kolbe-Stenholm and Graham proposals). Or, in another example, if DIBEN.cabr_a_pct=100 (i.e., there is no conversion-age reduction in the PIA), an oabr_pct value of 2.5 will produce a 100 percent reduction in the DI PIA (all the way down to the OAI PIA) when the DI-onset age is 62, no reduction when the DI-onset age is 22, and a 50 percent reduction when the DI-onset age is 42.

Valid values: 0.0 to 100.0, Real

Source code: policy.h and policy.cpp for reading the parameter from the input database and oasdi.cpp for using the parameter in DI benefit computations.

SSASIM:   DIBEN . nraconvert
Specifies whether or not disabled-worker beneficiaries are converted to retired-worker beneficiaries at their normal retirement age (NRA). The value of this policy parameter under current law through at least 2004 is true. Setting it to false implies DI beneficiaries are not converted to OAI beneficiaries at their NRA, and therefore, remain on the DI program until they die.

Valid values: T (=1) or F (=0) (for true or false), Logical

Source code: policy.h and policy.cpp for reading the parameter from the input database and oasdi.cpp for using the parameter in DI benefit computations.

SSASIM:   DIBEN . erainelig
Specifies whether or not people are ineligible to become disabled-worker beneficiaries at their early retirement age (ERA) and after. The value of this policy parameter under current law through at least 2004 is false: people can become disabled-worker beneficiaries up until their NRA. Setting it to true causes the model to simulate an early retirement event for those who become disabled at any age ranging from their ERA up to just before their NRA.

Valid values: T (=1) or F (=0) (for true or false), Logical

Source code: policy.h and policy.cpp for reading the parameter from the input database and oasdi.cpp for using the parameter in DI benefit computations.

SSASIM:   DIBEN . ks_br_type
Specifies whether or not DI-conversion-age benefit reduction called for by setting DIBEN.cabr_a_pct less than 100 is implemented using a Kolbe-Stenholm-type benefit reduction scheme. If this parameter is false, then a Graham-type benefit reduction scheme is used instead. The Kolbe-Stenholm scheme reduces benefits in proportion to the difference in the disabled-worker PIA and the retired-worker PIA at the DI-onset age. The Graham scheme reduces benefits in proportion to the difference in the disabled-worker PIA and the retired-worker PIA at the DI-conversion age. This parameter comes into play only when DIBEN.cabr_a_pct is less than 100 and when the PIA formula for disabled workers produces a larger PIA than does the PIA formula for retired workers.

Valid values: T (=1) or F (=0) (for true or false), Logical
