Analyse impact on the UK Cheapest world supplier was not EU but say New Zealand, represented by Sworld + tariff so price is Pw + tariff Creation of FTA, we now buy at PFTA from eg France, so consumer surplus increases by A+B+C+D Producer surplus falls by A, and we lose C + E in revenue from the tariff So welfare gain is B + D - E, so if E is greater than B + D there is an overall loss in welfare The loss in revenue will be greater the greater the original difference in prices between France and NZ
