How should we address today's big problems, and what we can take from icons of economics past? How would John Maynard Keynes have resolved today's debt problem, or how would Adam Smith have assessed the European carbon emission trading market? This book applies the ideas of ten renowned economists (Marx, Minsky, Keynes, Knight, Bergmann, Veblen, Sen, Myrdal, Smith, Robinson) to real world economic problems, directly or indirectly related to the causes and consequences of the 2008 financial crisis. Each chapter presents an economist, and structures the 'problem', the 'insight' (the economist's idea), the 'economist' (short bio), and two 'practices' offering real-world alternatives. This book presents a lively and original approach that will be of interest to economists and non-economists alike, discussing key elements of an economics for a postcapitalist economy and connecting policy insights to real-world problems of today.
