The focus of our analysis is on how the UK government's proposed Brexit deal is likely to affect the economy. First, we assess how trade, migration, foreign direct investment, productivity and contributions to the EU budget might change by reviewing current proposals against historical evidence. Second, we use the National Institute Global Econometric Model (NiGEM) to analyse the macroeconomic effects. Our assessment is that trade with the EU, especially in services, would be more costly after Brexit. This would be likely to have adverse effects on living standards in the UK. Our central estimate is that if the government's proposed Brexit deal is implemented, then GDP in the longer term will be around 3% lower per head than it would have been had the UK stayed in the EU. If the UK were to stay in a customs union with the EU, or if the Irish backstop position was to be invoked, there would still be a hit to GDP per capita of 2%. These estimates represent our considered view of the economic impact of the government's proposed Brexit deal, but they are themselves uncertain as there is no historical precedent of a country leaving a major trading block such as the EU.
