70 -- DYNAMIC MICROSIMULATION MODELS SOL WTO98DMM DUE 032598 POC Wanda T. Owens (410) 965-8095/Michelle Burgesen (410)965-9462 E-MAIL: Contracting Officer, Wanda.Owens@ssa.gov. Social Security Administration (SSA) intends to evaluate the benefits of using dynamic microsimulation models to assist in performing cost and distributional analysis on Social Security solvency proposals. SSA intends to purchase the rights to an existing microsimulation model, including appropriate technical support. SSA will perform a hands-on evaluation of the model, with the goal of determining if SSA should bring the model in on a long-term basis. The microsimulation model must have the following functionality: 1) a robust Social Security sector with the capacity to: a) model the three scenarios for restoring SSA's financial solvency as presented by the Advisory Council on Social Security, b) evaluate earnings sharing proposals, and c) analyze the money's worth for individuals and various demographic groups. 2) Treats individuals and families as fundamental economic units. 3) Is modularly structured so that modifications can be made to single modules without compromising the overall model's integrity. 4) Uses current information. 5) Has adequate documentation. 6) Is a commercially available off-the-shelf product. SSA knows of only one dynamic microsimulation model that meets all of the above requirements; Corsim, which is owned by Strategic Forecasting, Inc. Any responsible firm that has the capability to provide this requirement to SSA may send complete information discussing such capabilities; i.e., descriptive literature/brochures; and, if applicable, GSA Schedule information. Please refer to WTO98DMM. Responses may be transmitted via facsimile to either 410-965-9560 or 410-966-5982. The information respondents provide shall pertain to this synopsis only. Respondents will not be notified of the results of the evaluation of the source data received. No cost or pricing data is required or requested. This is not a request for proposal and requests for copies of a solicitation will not be honored or acknowledged. Interested partiesmust respond in writing within 15 calendar days from the date of this publication. If after 15 days of this Notice no viable responses have been received, SSA shall negotiate with Strategic Forecasting, Inc. on a sole source basis for its proprietary software product. (0070)
