  1. HMRC commissioned PwC to construct a UK Multi-Regional Computable General Equilibrium (MR-CGE) model. The model extends the current HMRC Tax CGE model and therefore improves the analytical capabilities of HMRC. HMRC will be able to use the new model to capture the inter-regional economic interactions among England, Northern Ireland, Scotland and Wales. This document sets out the documentation of the MR-CGE model describing how it has been constructed, the data used and highlighting the differences with a single country CGE model.
