This trilogy deals with an epistemology of economics, arguing for a radical overturning of conventional analysis and providing an alternative to political economy and social sciences, based not on positivism, but on a normative and programming paradigm. Volume II builds on the work presented in Volume I to explore oppositions to the traditional and conventional teaching of economics, and presents testimonies that are favourable to a trend towards a programming approach, thereby giving substance to the epistemological overturning of conventional analysis. Such oppositions studied include the work of Ludvig von Mises and his theory of praxeology; Ian Tinbergen and Wassily Leontifs preference for planning over forecasting science; Bruno de Finetti and Daniel Bells support for the base of utopia in economics; the trend from the theory of planning towards the methodology of planning, by Andreas Faludi; neoclassic curiosity about the multi-purposes approach and non-economic commodities as investigated by Walter Isard, as well as theories expressed by Herbert Simon, Robert Lucas, George Soros and Mark Blaug. Volume III takes studies further and presents a concrete and practical example of how to build a Planning Accounting Framework (PAF), as associated with Frischs plan-frame (explored in Volume II), to demonstrate the extent to which decisions and negotiations can be routed in the social sciences.
