A meta-regression analysis of benchmarking studies on water utilities market structure

Carvalho, Pedro and Marques, Rui Cunha and Berg, Sanford (2011): A meta-regression analysis of benchmarking studies on water utilities market structure.

Abstract

This paper updates the literature on water utility benchmarking studies carried out worldwide, focusing on scale and scope economies. Using meta-regression analysis, the study investigates which variables from published studies influence these economies. Our analysis led to several conclusions. The results indicate that there is a higher probability of finding diseconomies of scale and scope in large utilities; however, only the results for scale economies are significant. Diseconomies of scale and scope are more likely to be found in publicly-owned utilities than when the ownership is mostly private; as would be expected, multi-utilities are more likely to have scale and scope economies.
