The Economic Structure of International Trade-in-Services Agreements
构建了一个模型来解释《服务贸易总协定》强调“深度一体化”等关键特征，并指出服务贸易自由化可能在深度与浅度一体化之间存在中间地带。
The existing economics literature on international trade agreements focuses on tariff agreements covering trade in goods and explains core features of the General Agreement on Tariffs and Trade (GATT). Tariffs play almost no role in services markets, however, and the literature cannot account for the strikingly different approach to trade liberalization in agreements such as the World Trade Organization’s General Agreement on Trade in Services (GATS). We develop a model through which key features of GATS, including its emphasis on “deep integration” can be understood. And we use this model to suggest that there may also be a middle ground for services trade liberalization between the GATS deep-integration approach and the traditional “shallow-integration” approach of GATT.
