| The objective of this work was to analyze the cost allocation of improvements in river basins among the water users. It was used, as example, the Paraíba do Sul river basin, located in the states of Minas Gerais, São Paulo and Rio de Janeiro, and, as criteria of allocation of costs, they were used the volumes of water extracted and consumed, and the quantity of pollutants deposited in the basin area by water users. The methodology used consists of the rule of allocation known as Shapley value, which belongs to the cooperative branch of game theory. In the case of Paraíba do Sul river basin, the values found indicated that the urban users should pay the higher part of the costs of improvements, given that these users are responsible for most of the... |

| 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... |
