Analysis of technical efficiency and productivity of water and sewage services in Brazil, 2006 to 2013

Abstract

The regulatory framework of the National Basic Sanitation Law introduces fundamental changes in the provision of water supply, sewage collection and treatment services. The objective of this text is to study the efficiency and productivity of the sector after this law applying the Data Envelopment Analysis (DEA) method in a sample with 27 representative providers of each entity of the federation between the years of 2006 and 2013. The results for the static analysis indicate low efficiency scores with great disparity between the regions. The dynamic analysis showed that the period of greatest productivity improvement occurred between the years of 2010 and 2013 led by the expansion of the frontier.
