This study uses panel data at suburb level to estimates the elasticity water demands in Perth, Australia from 1995 to 2005. After deriving the consumer’s water demand under a non-linear budget constraint, we estimate the water demand model, which accounts for how water (and other purchased...

Appropriate pricing of water is critical for improving the efficiency of pipe-borne water supply systems in many developing countries. However, existing literature on residential, industrial and commercial water demand has primarily focused on developed countries. This paper estimates the demand...

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...

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...

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...

Survey data from over 1,600 households in ten countries were used to analyse the determinants of residential water demand. Results show that in every country the price elasticity is negative and statistically significant. Households that do not have to pay for the water they use (volumetric...
