This book helps readers identify feasible and morally plausible reforms of global institutional arrangements and international organizations. A distinctive, practically oriented contribution to debates about global justice, this work: helps readers to examine the fairness of global rules and institutions; integrates philosophical thinking about normative responsibility with discussion of practical dilemmas concerning organizations such as the WTO, and rules governing the use of force internationally; brings together original articles by political philosophers, legal theorists, and economists; and, considers the aims of global justice, the institutional arrangements that are required to realise them, and the allocation of responsibilities to promote the required institutional reforms.
