On the Virtues of Multilateral Trade Negotiations*

Abstract

Phasing out distortionary government subsidies and barriers to international trade will yield extraordinarily high benefits relative to any adjustment costs, notwithstanding the considerable reforms that have already taken place over the past two decades. The present paper surveys recent estimates, using global economy-wide simulation models, of the benefits of reducing remaining distortions by means of unilateral reform, multilateral trade negotiations and preferential trading arrangements. Distortionary trade policies harm most the economies imposing them, but the worst of them (in agriculture and clothing) are particularly harmful to the world's poorest people. Opportunities to reduce remaining distortions, including by means of the WTO's Doha Development Agenda as compared with subglobal preferential reform, are examined, before drawing out the implications of liberalisation for poverty and the environment.
