摘要：

This study estimates the price elasticity of the demand for water using a panel data model for 5570 Brazilian municipalities in the period 2011-2017. Given the country's environmental and socioeconomic heterogeneity, regional demand elasticities are also estimated for each unit of the Federation. The results suggest demand for water is inelastic to the price. Since water is essential to life, it is reasonable to assume that the demand for water is relatively inelastic to the price level. However, for Brazil as a whole, the parameter associated to real tariff variations was significant at the 1%. The estimates effects also suggest that users tend, to some extent, to change water consumption levels. This may occur mainly, where consumption levels are relatively higher compared to the minimum required for survival. This relationship was significant in 25 of the 27 Brazilian states. It is concluded, therefore, that tariff policy could be an effective instrument in reducing water consumption.
