Building on a recent groundbreaking OECD/World Bank seminar, this volume explores whether and how trade liberalisation can contribute to achieving universal service goals and the types of complementary policies required.  It focuses on experiences in four sectors - telecommunications,  water and sanitation, financial services, and electricity. The unique multi-sector perspective taken in this book, together with the national case studies, yield insights which can help countries promote their universal access goals. A horizontal assessment also helps determine how far the current services negotiations in the WTO, under the General Agreement on Trade in Services, can aid the attainment of universal service goals.
