Multilateral Tariff Cooperation during the Formation of Free Trade Areas
研究自由贸易协定的形成如何影响多边关税合作，发现初期会因平衡被打破而出现多边贸易政策倒退，但长期看随着自贸协定对贸易格局的影响充分显现，自由的多边贸易政策可恢复。
We consider the impact of the formation of free-trade agreements on multilateral tariff cooperation. We assume that countries are limited to selfenforcing multilateral arrangements that balance the gains from deviating against the costs of an ensuing trade war. We find that the emergence of free-trade areas will be accompanied by a temporary retreat from liberal multilateral trade policies, as the initial balance supporting multilateral cooperation is upset. Eventually, however, as the full impact of the emerging free-trade agreement on multilateral trade patterns is felt, this initial balance tends to reemerge, and liberal multilateral trade policies can be restored.
