摘要

我们利用边际电价方案的突然变化，利用雅加达大都市区坦格朗县的家庭和公司数据来估计水需求的价格弹性。由于城市人口和工业活动的增长，坦格朗县的水需求管理势在必行。在我们的研究中使用了消费者层面的月度用水量数据集。利用时间不连续回归(RDiT)方法，我们发现家庭消费者用水需求的价格弹性为- 0.32，对价格变化无弹性。相比之下，工业和商业消费者的弹性为- 1.16，意味着更有弹性的反应。研究结果引起了人们的担忧，即企业会替代更便宜的水源，危及该地区水资源的可持续性。

Exploiting unanticipated change in block rate pricing for water demand elasticities estimation: Evidence from Indonesian suburban area

We exploit sudden changes in the marginal tariff scheme to estimate the price elasticity of water demand using households' and firms' data in Tangerang Regency, a part of the Jakarta Greater Metropolitan Area, where water demand management is imperative due to the city's growing population and industrial activities. A monthly water consumption dataset at the consumer level is used in our study. Using the regression discontinuity in time (RDiT) approach, we find the price elasticity of water demand is −0.32 for household consumers and inelastic to changes in price. In contrast, elasticity for industrial and commercial consumers is −1.16, implying a more elastic response. The results raise concerns that firms substitute for a cheaper water source, endangering the water resources sustainability in the area.

期刊介绍： Water Resources and Economics is one of a series of specialist titles launched by the highly-regarded Water Research. For the purpose of sustainable water resources management, understanding the multiple connections and feedback mechanisms between water resources and the economy is crucial. Water Resources and Economics addresses the financial and economic dimensions associated with water resources use and governance, across different economic sectors like agriculture, energy, industry, shipping, recreation and urban and rural water supply, at local, regional and transboundary scale. Topics of interest include (but are not restricted to) the economics of: Aquatic ecosystem services- Blue economy- Climate change and flood risk management- Climate smart agriculture- Coastal management- Droughts and water scarcity- Environmental flows- Eutrophication- Food, water, energy nexus- Groundwater management- Hydropower generation- Hydrological risks and uncertainties- Marine resources- Nature-based solutions- Resource recovery- River restoration- Storm water harvesting- Transboundary water allocation- Urban water management- Wastewater treatment- Watershed management- Water health risks- Water pollution- Water quality management- Water security- Water stress- Water technology innovation.
