Filippini, Massimo Kuenzle, Michael 2003 In this paper we have examined the scale and cost efficiency of Italian and Swiss regional bus companies. For this purpose, we have used the estimation of a frontier cost model using a fixed effect approach. Two translog cost frontier models were specified and estimated using panel data. The first model was estimated for a sample of 58 Italian bus companies, whereas the second model was estimated for a sample of 55 Swiss bus companies. The findings on efficiency were discussed in the political and regulatory setting under which the Swiss and the Italian regional bus companies are operating. application/pdf https://susi.usi.ch/global/documents/318006 https://localhost:5000/ark:/12658/srd1318006 https://susi.usi.ch/documents/318006/files/1_wp0301.pdf ita info:eu-repo/semantics/altIdentifier/ark/12658/srd1318006 info:eu-repo/semantics/openAccess License undefined info:eu-repo/classification/udc/33 Analisi dell’efficienza di costo delle compagnie di bus italiane e svizzere http://purl.org/coar/resource_type/c_816b
