Trade Agreements

Question: To ask the Secretary of State for Business and Trade, whether his Department has updated its computable general equilibrium models to incorporate post-2024 trade flow data.

Answer: DBT uses data provided by the Global Trade Analysis Project (GTAP) for CGE modelling. The latest publicly available data is GTAP 11 with the latest reference year 2017. As a consortium member of the Project, we have early access to forthcoming newer versions before they are published. Making use of this we used the pre-publication GTAP 12 dataset, with latest reference year 2019, for the modelling presented in the Impact Assessment of the UK-India Free Trade Agreement.
