Résumé
This article proposes to model seasonal patterns of residential waterdemand using the techniques of seasonal integration and cointegration.The methodology is applied to quarterly aggregate time series data forTunisia (1980–2007), applying the same increasing, multi-step pricingscheme in the whole country. First, a seasonal cointegration analysisdemonstrates the relevance of a pricing policy that increases the size ofthe lower consumption block in summer. Second, the nonseasonal cointegrationanalysis reveals a relatively high price elasticity for the highestconsumption block. Therefore, we also propose to increase the tariffprogressivity to promote water savings. This modified pricing schemewill help to achieve goals of environmental protection and social equity.
