‘Everyone loses’ if Britain exits EU

If Britain leaves the European Union, it could knock up to 14% off its GDP by 2030, taking into account all negative factors including lost economic dynamism, a study by two leading German institutes has found.

Based on 2014 values, Britain’s GDP could be €313bn lower — or €4,850 per capita — by 2030 in a worst-case scenario, the study released yesterday by the Bertelsmann Foundation and Ifo economic research institute said.

Under more favourable circumstances, such as Britain forging free trade agreements with the EU from outside the bloc, real per capita GDP could end up between 0.6% and 3% lower, or between €220 to €1,025 per capita.
