Regional Integration as Diplomacy [PDF]

open access: yesThe World Bank Economic Review, 1998
Regional integration agreements (RIAs) are examples of second best and have an ambiguous impact on welfare, contend the authors. They build a model in which RIAs unambiguously raise welfare by correcting for externalities. It assumes that trade between neighboring countries increases trust between them and reduces the likelihood of conflict.
