International rules on trade in goods are at the core of the multilateral trading system and have been influential in all areas of trade law. The essays in this collection represent the very best academic writing from six decades of international trade law and policy. They range from seminal analyses of the core non-discrimination principles to explorations of areas that are still evolving, such as rules on trade remedies, regional trade agreements and developing countries. Alongside analytical pieces, the editors have included a number of essays with a comparative, institutional, political or economic perspective with an introduction offering their own perspective on these themes. This volume is an essential guide to the legal complexities, controversies and policy implications of the field.
