Measuring and comparing the efficiency of water utility companies: A data envelopment analysis approach
چکیده انگلیسی

This study provides an analysis of Italian water utilities to determine the effects on their efficiency of certain relevant variables that have been broadly discussed in the existing literature. We reviewed the annual financial statements of 43 Italian water utility companies and obtained other technical data from Co.n.vi.r.i., the Italian national authority for water. Using data envelopment analysis we assessed their cost efficiencies and, using non-parametric statistic methods, we discuss the significant differences among clusters.We found that ownership structure, size and geographical location had an impact on the performance of water utilities, although with different degrees of significance.


► Public owned firms are more efficient compared with mixed owned companies.
► Companies located in central-southern Italy are more efficient than northern ones.
► Economies of scale exist and involve medium firms, with more than 50,000 customers.
