This paper develops a model of residential water demand under a nonlinear budget constraint. The theoretical model for an individual consumer is adapted to yield an aggregate model that preserves the structure of the individual demand function, and that can be used with aggregate (water district...

This study uses panel data at suburb level to estimates the elasticity water demands inPerth, Australia from 1995 to 2005. After deriving the consumer’s water demand under anon-linear budget constraint, we estimate the water demand model, which accounts forhow water (and other purchased goods)...

This paper formulates a demand model for residential water in Sri Lanka using the Stone-Geary functional form. This functional form has two main advantages when compared with Cobb-Douglas: non-constant price elasticities and; it considers water consumption as two components – a fixed and a...

Water demand management requires the implementation of instruments and strategies that consider pricing, mandatory water conservation requirements and the engagement of the public and private sectors as well as of the society at large. In the case of Singapore, water is treated as an economic...

This paper formulates a demand model for residential water in Sri Lanka using the Stone-Geary functional form. This functional form considers water consumption to be composed of two parts—a fixed and a residual component. The presence of these two components means it is possible to estimate a...

A panel of monthly aggregate data from the Northwest of Spain is used to estimate domestic water demand functions under linear and non-linear tariffs. Price, billing, climatic, and sociodemographic variables are used as explanatory variables. The use of intraannual data constitutes a relevant...

The price specification suggested by Nordin (1976) for theanalysis of demand under block tariffs is applied to estimatewater demand functions using aggregate data from the Northwest ofSpain. The traditional way of using Nordin's specification whenonly aggregate data are available (using values...

This paper explains the economic conception of water - how economists think about water. It consists of two main sections. First, it reviews the economic concept of value, explains how it is measured, and discusses how this has been applied to water in various ways. Then it considers the debate...
