Antonioli, Barbara Fazioli, Roberto Filippini, Massimo 2000 The purpose of this study is to analyse the cost structure of a sample of Italian refuse collection firms in order to assess economies of scale and density so to estimate economic rationality of competition in the refuse collection. A translog cost function was estimated using panel data for a sample of 12 firms of refuse collection operating at provincial level over the period 1992-1995. The results indicate the existence of economies of density and scale for most output levels. The empirical evidence suggests that franchised monopolies, rather than side-by-side competition, is the most efficient form of production organisation in the refuse collection sector. application/pdf https://susi.usi.ch/global/documents/317974 https://n2t.net/ark:/12658/srd1317974 https://susi.usi.ch/documents/317974/files/1_wp0007.pdf ita info:eu-repo/semantics/altIdentifier/ark/12658/srd1317974 info:eu-repo/semantics/openAccess License undefined info:eu-repo/classification/udc/33 Il servizio di igiene urbana tra concorrenza e monopolio http://purl.org/coar/resource_type/c_816b
