“…In general, composite indicators are very familiar in country performance comparison in globalization, competitiveness, education, health, human rights, ecological footprint, corruption, quality of work, technology achievement, social cohesion and trust in public institutions (OECD 2008;Marozzi 2012;Isljamovic et al 2014). Other fields where composite indicators have been successfully used are: quality assessment of industrial products (Lago and Pesarin 2000), customer satisfaction (Arboretti et al 2007;Marozzi 2009) and analysis of industrial development policies (Barbieri et al 2012). Interesting reviews on composite indicator computation are Hochbaum and Levin (2006), Aiello and Attanasio (2004), the key-point is the selection of methods to transform, aggregate and weight the variables at the basis of a composite indicator, in particular both linear and non linear transformation methods are described.…”
