This paper investigates how pre-existing preferential trade agreements (PTAs) dilute the trade creation effect and shield the trade diversion effect of new PTAs. Countries having pre-existing PTAs enjoy smaller gains in intra-bloc trade because of the dilution effect and experience smaller losses or even gains in extra-bloc trade because of the shielding effect. The findings support the proposition that PTAs could be used to fend off future trade diversion.
