La mobilit? come common ambientale: uno schema per la valutazione delle politiche

La mobilit? come common ambientale: uno schema per la valutazione delle politiche - The debated issue of sustainable mobility has become one of the main points on every decision-maker agenda since the last thirty years. The idea proposed in this work is to redefine the resource ?mobility? as a common good, which is produced by a collective action. In other words, the mobility of people and goods is both a structural aspect of the issue of environmental common reconstruction and a fundamental asset of a community of agents? social capital. The common good is thus socially constructed through the system of rights related to its use, reproduction or destruction, generated by the relationship network between agents. In the literature the debate seems mainly focused on the regulation of competition under conditions of ?externalities ? or market ?failures?, or on regulator failures, while a careful consideration of the strict linkage between structural generators (economic growth, demographic pressure, infrastructural weaknesses) and simultaneous failures both of the market and of the regulation policies can be rarely found. For this reasons, the aim of the present work is the construction of appropriate methodologies for the evaluation of scalable mobility policies suitable to be adopted from local level decision-makers to wider areas. Using an institutional framework that includes this social and iterated definition of the resource ?mobility?, we build indicators capable of modelling a traffic jam in its subjective determinants, and in order to check their reliability we test them against several case studies. The paper is completed by the formalisation of an example mobility policy, carried out using the proposed indicators. JEL Q01, D62, D85, L91, K23
