''Welfare Effects of Access to Water Service in Cambodia''
( 2011, Vol. 31 No.3 )
From data collected by questionnaire survey of three communes in the Kandal province of Cambodia, where public water supply remains inaccessible, this study estimates the demand function for drinking water and finds that the price elasticity is between -0.26 and -0.29. Based on this, and given the price set by the Phnom Penh Water Supply Authority, expansion of service would increase per capita water consumption by 9.8 liters per day, increase consumer surplus by 4.6 percent of total expenditure and decrease the number of households surviving on less than 30 liters of water per day by 5.3 percent. A simulation is used to calculate the water price such that the benefit of water connection exceeds the cost.
