The interviews with unconventional economists published in this book are reprints from a bi-annual Germany-/Austria-based journal which started as INTERVENTION. Zeitschrift für Ökonomie / Journal of Economics in 2004 and which was re-launched with Metropolis Publisher in 2008 as INTERVENTION. European Journal of Economics and Economic Policies. The unconventional economists interviewed for the journal from 2004 to 2012 are leading and well-known experts in their fields of research and they have contributed to the development of non-neoclassical economics to a significant degree. Especially for the younger generation of critical economists their work is of particular interest and a point of reference. Philip Arestis Anthony Atkinson Barbara R.
