Improving efficiency in the MSW collection and disposal service combining price cap and yardstick regulation: The Italian case.

Municipal solid waste collection and disposal service is a key element of the European strategy aimed at moving towards a circular economy. An efficient municipal solid waste collection and disposal is closely related to both lower waste tax and higher welfare of the interested population. In Italy, the lack of a centralized regulatory framework has determined heterogeneous performances of sector operators across the country. Firstly, we estimate the productive efficiency in different optimal territorial areas and secondly we forecast the economic benefits that would arise under a new regulatory regime. Our approach combines the well-known yardstick competition and the price-cap mechanisms. Results suggest that if all territorial areas converged to the most efficient ones, a potential saving between 12% and 19% emerges, i.e., up to €2bn savings out of €10.05bn total tax revenue in 2015, the reference year.
