We show that FTA members retain positive internal tariffs even if they seek to maximize their joint welfare. Requiring FTAs to eliminate internal tariffs — as stipulated by current WTO rules — makes the non-member better o§ although it simultaneously reduces the likelihood of achieving global free trade by encouraging free-riding on its part. While the WTO’s non-discrimination constraint is not necessarily conducive to reaching global free trade, it raises welfare in a tariff-ridden world.
