“…In Seroa daMotta and Moreira (2006), the authors compute returns to scale using a DEA approach with data from Brazil. Findings from this study will be discussed later.2 The International Benchmarking Network (IBNET) is developed and managed by the World Bank with the objective to improve the service delivery of water supply and sewerage utilities through the provision of international comparative benchmark performance information.…”

RESUMO O presente trabalho visou avaliar, por meio de regressão linear múltipla (RLM), os indicadores que melhor exprimem a realidade dos sistemas de abastecimento de água de municípios de pequeno porte, com base nos desempenhos financeiro, operacional e de qualidade da água como variáveis de resposta. A organização e a seleção dos dados fiaram-se no Sistema Nacional de Informações sobre Saneamento de 2014, tendo sido selecionados os referentes a 182 municípios de Minas Gerais com população inferior a 10 mil habitantes e 56 indicadores como variáveis explicativas. Por meio da RLM, verificou-se que o comprometimento das receitas com a despesa (margem da despesa de exploração) e a razão entre a arrecadação e as despesas (índice de suficiência de caixa) são as variáveis mais relevantes para descrever o desempenho financeiro. Para descrição do desempenho operacional, os índices de perdas por ligação e de faturamento de água foram os mais recorrentes. Por fim, no que tange ao desempenho de qualidade da água, os modelos apresentaram baixos coeficientes de determinação e a não aderência dos resíduos à distribuição normal.

“…Setting up the regulatory framework for sanitation services is a challenge since the sector exhibits natural monopolies, low technological dynamism, different degrees of technology adoption, and movement toward the productive frontier [13] (Galvao Junior 2009). All of these reasons lead to differences in service provision.…”

a b s t r a c tChildren are prone to the contagion of waterborne diseases without adequate water and sanitation services. When not sick, children and their caregivers without proper access to such services have to allocate their leisure time in order to meet their water and sanitation needs. It is through these health and leisure time use changes that access to water and sanitation services impacts the educational attainment of children. This paper proposes a household utility maximization model in which access and sanitation services determine the child's health, which in turn affects the child's education and the household welfare.Comparative statics indicate that households consider the health gains to the market value of their leisure time, and the changes in the consumption of other goods. The model is applied to data from Brazil. In order to sort out the endogeneity between provision of water and sanitation services, and educational attainment, the paper uses an instrumental approach, based on the technical features of the water systems and an instrument that measures a proxy of water availability within the municipality territory. Estimates suggest that access to water and sanitation services has a positive and significant effect on schooling, when measured by the completed number of school years. These positive effects call for the expansion of the laggard sewerage systems in the country, both at home and at school.
