Mr. Heald
To ask the Secretary of State for Work and Pensions if he will make a statement on the use of the policy simulation model by his Department; and if he will place its specifications in the Library. [125950]
Malcolm Wicks
The Department for Work and Pension's Policy Simulation Model is a static microsimulation model used by analysts within the department to estimate the budgetary and distributional impacts of a range of hypothetical and actual policy changes. The model is similar in purpose and functionality to those maintained by HM Treasury (IGOTM), the Institute for Fiscal Studies (TAXBEN) and the Cambridge Microsimulation Unit (POLIMOD). An overview of the model has been placed in the Library.
