Every major regional trade agreement now has a services dimension. Is trade in services so different that we need to modify the conclusions on preferential agreements reached so far in the realm of goods? This paper examines, first, the implications of unilateral policy choices in a particular services market. It then explores the economics of international cooperation and identifies the circumstances in which a country is more likely to benefit from cooperation in a regional rather than multilateral forum. Finally, it reviews some evidence on services liberalization under the European Union's Single Market Program.
