'This interdisciplinary volume provides a fresh look at a perennial problem: the role of economic inequality in producing intergroup conflict. Its wealth of insights from its distinguished authors will stimulate academic and policy debate for years to come.' - Donald L. Horowitz, James B. Duke Professor of Law and Political Science, Duke University, USA 'Innovative and insightful, this is a timely book now that both the disequalising forces of globalisation and internecine conflicts over resources have heightened ethnic and racial conflicts in many countries. This is not only an excellent academic text but also an accessible source for all engaged in peace building and conflict prevention.' - Thandika Mkandawire, Director, United Nations Research Institute for Social Development '...high-quality, innovative empirical research...' - Journal of Peace Research
