Policy Simulation Model (original) (raw)
The Policy Simulation Model (PSM) is a static microsimulation model which encapsulates the tax and benefits system, and population, of Great Britain. It is based on survey data from the Family Resources Survey (FRS) which is uprated to simulate the current year, together with several years into the future through a process of static uprating. The uprating process covers a complex range of processes, ranging from simple numerical uprating of financial values, to modelling the draw-down of old benefits through to the implications of the rising state pension age.
