  • The most efficient clusters of Brazilian water companies

    Usually water utilities provide their services under natural monopoly, with few incentives to become efficient, therefore affecting customers in the form of expensive tariffs. Hence, it is extremely important to find out the sources of inefficiency. The present study aims to identify the most efficient water utility groups in Brazil. For this purpose, a robust non-parametric method was ...
