This paper compares cost efficiencies of Brazilian public and private companies of water supply. To measure efficiency a Cobb-Douglas stochastic cost frontier model including technical effects is estimated by maximum likelihood to a panel of Brazilian firms for the period 2002 -2004. The statistical results indicate that there is evidence that public firms are more efficient although the difference in efficiency is declining over time. Overall the system of water and sewerage supply is becoming more efficient over time.

This paper explores the link between voters’ information, corruption, and efficiency in the context of a career concern model, where politically connected local monopolies are in charge of the provision of a local public service. We find that both a corrupt environment and a low level of voters’ information on managerial actions induce managers to reduce effort levels, thereby contributing to drive down efficiency. We test our predictions using data on solid waste management services provided by a large sample of Italian municipalities. We estimate a stochastic cost frontier model that provides robust evidence that services produced in more corrupted regions with low voters’ information are substantially less cost-efficient.
