DP1705 Protection and Trade in Services: A Survey
This paper surveys the literature on trade in services, focusing on the policies that are used to restrict such trade, the gains from liberalization, and the institutional mechanisms that have been adopted in the pursuit of liberalization. It argues that technological progress and international trade negotiations are likely to keep liberalization of trade in services a high profile policy issue. It also suggests that the research agenda should focus on developing better estimates of the welfare costs of protectionism in the service sector. This will require the quantification of barriers to the international exchange of services.
