Abstract

Este trabalho objetivou analisar as mudanças ocorridas na despesa com água e esgoto, em resposta à alteração na renda das famílias nas regiões Norte, Nordeste, Centro-Oeste, Sudeste e Sul. Para isso, estimou-se a elasticidade-renda da despesa por meio de um modelo econométrico que consiste em ajustar uma poligonal com três segmentos, com vistas em mostrar como a despesa com água e esgoto varia em decorrência de uma alteração no recebimento familiar. Os dados foram extraídos da Pesquisa de Orçamento Familiar de 2002/2003, realizada pelo IBGE. Os valores encontrados para elasticidade-renda situaram-se entre 0 e 1, o que indica que a água pode ser considerada um bem normal nas regiões analisadas e no Brasil, onde o valor encontrado foi de 0,4263. As estimativas mostraram ainda que, quase sempre, a elasticidade-renda das despesas com água e esgoto no meio rural é maior do que no meio urbano.----------------------The objective of this paper was to analyze the expense changes with water and sanitation taxes in response to change in households’ income in the main Brazilian regions (North, Northeast, Central-West, South East, and South). The data were collected from the Household Budgetary Research (POF) of IBGE for the period 2002/2003. Elasticity-income of expenditure was estimated through an econometric model which consisted of an adjusted polygonal with three segments. The values encountered for the elasticity-income of expenditure are between 0 and 1, indicating that water can be considered a normal good in the regions analyzed, and, for the country as a whole, the value encountered was 0.4263. The estimations show also that, in general, the elasticity-income of expenditure of water and sanitation taxes is higher in rural areas than in urban areas.
