Returns to Regionalism: An Analysis of Nontraditional Gains from Regional Trade Agreements
分析了区域贸易协定可能带来的非传统收益，包括可信度、信号传递、谈判力、保险和协调，并评估了这些收益的适用条件和整体可信度，最后以北美自由贸易协定和欧洲协定为例进行检验。
The past decade has witnessed a renewed interest in regional trade agreements, with many policymakers and academics seeming to believe that these provide more than the traditional gains from trade. This article examines several possible benefits that regional trade agreements may confer on their partners, including credibility, signaling, bargaining power, insurance, and coordination. It assesses the necessary conditions for each possible channel to work, gives stylized examples of specific types of policy where the benefit might be applicable, examines cases where the explanation might be relevant, and discusses their overall plausibility. It concludes by examining the North American Free Trade Agreement and the Europe Agreements.
