In this age of overlapping and mutually reinforcing deep global crises (financial convulsions, global warming, mass migrations, militarism, inequality, selfish nation-states, etc.), there needs to be more realistic dialogue about radical alternatives to the status quo. Most literature produced heretofore has focused on the surface causes of these crises without much attention given to the sorts of major societal changes needed in order to deal with the crises we face. This book moves the debate beyond the critiques and the false or not fully realised alternatives, to focus on what can be termed "practical utopias". The contributors to this book outline a range of practical proposals for constructing pathways out of the global economic, ecological and social crisis. Varieties of Alternative Economic Systems eschews a single blueprint but insists on dealing directly with the deep structural problems and contradictions of contemporary global capitalism. It provides a diverse array of complementary proposals and perspectives that can inform both theoretical thinking and practical action. This volume will be of interest to academics and students who study political science, ecological economics, international politics and socialism.
