“Beyond GDP”: A fuzzy way to measure the Country Wellbeing

This paper presents the development of two of the eight indicators to evaluate the Country Wellbeing. We start from the Stiglitz document (2009) that for the first time puts a fixed point on what are the indicators that, aggregated, produces a multidimensional description of wellbeing that goes beyond GDP. Following the document indications, we present a fuzzy approach for this measure as a proposal that overcome the deficiencies that the usual statistical methods produce. The country we have in mind is Italy, but the instrument we propose is not calibrate on this country, but may be useful for every country that share the Stiglitz document indications. The fuzzy instrument we propose is a fuzzy inference system that, by its rule-blocks, let the possibility to use verbal judgement about the importance of one input respect the others.
