'In this fine book, Armstrong has filled a significant gap in the literature by providing a very clear, learned, and comprehensive discussion of different approaches to global distributive justice and some of their apparent implications for pressing policy issues such as trade, immigration, and climate change.' Christian Barry, Australian National University 'This is a lively, clearly written and very helpful textbook that is accessible and yet philosophically engaging. It is not only of interest to undergraduates, new to the subject, but [it] also develops fresh arguments on various aspects of the debate, which will be of interest to people immersed in the literature.' Margaret Moore, Queen's University, Kingston, Canada 'This book does an excellent job of introducing students to some of the most interesting and significant philosophical arguments about global distributive justice. It also uses cases studies very well to demonstrate what is at stake in the abstract normative debates. It does students a tremendous service.' Darrel Moellendorf, Professor of Philosophy and Director of Institute for Ethics and Public Affairs, San Diego State University
