Britain is a week away from its historic economic decision on EU membership. Economists have never been more united in supporting a vote to remain, yet the profession increasingly appears incapable of persuading the public of Britain’s national interest.

Economic history is clear. The UK’s growth of national income per head has been the fastest in the G7 since joining in 1973, having been the slowest between 1950 and 1973. EU membership has served Britain well and has not prevented domestic economic renewal.

A battery of evidence shows the EU creates trade rather than diverts it. All other relationships with the EU and others throw up greater tariff or non-tariff barriers. Trade enhances competition and productivity growth, the elixir of prosperity. Britain is not burdened by EU red tape; its most damaging regulations are home grown. Although EU immigration is unlikely to make the British-born much better off, there is no evidence migrants take jobs and precious little that they harm wages or public services.
