Should we have a WTO for international migration?
探讨国际移民自由化能否通过类似WTO的贸易合作机制实现，发现由于移民主要基于绝对优势而非比较优势，缺乏互惠谈判基础，因此WTO式的合作框架难以推动移民自由化。
International migration: The international movement of labour remains much more restricted than movement of goods or capital, and the worldwide economic gains to liberalizing migration are large. This paper asks whether those gains could be realized through better international cooperation on migration along the lines of the WTO for trade. Although public opinion is marginally more negative towards the liberalization of migration than of trade, the key impediment is the lack of a basis for reciprocity in negotiations over migration. And this is because migration is largely driven by absolute advantage rather than by comparative advantage as in the case of trade. Consequently there is no basis for WTO-style negotiations over migration and therefore no grounds for reforming the international architecture in the hope of fostering liberalization.
