Is the WTO Passé?
综述经济学文献，认为WTO并未过时，仍应得到强力支持，而对近期兴起的特惠贸易协定应持更谨慎态度。
The WTO has delivered policy outcomes that are very different from those likely to emerge out of the recent wave of preferential trade agreements (PTAs). Should economists see this as an efficient institutional hand-off, where the WTO has carried trade liberalization as far as it can manage, and is now passing the baton to PTAs to finish the job? We survey a growing economics literature on international trade agreements and argue on this basis that the WTO is not passé. Rather, and subject to some caveats, our survey of research to date suggests that the WTO warrants strong support while a more cautious view of PTAs seems appropriate.
