Response of residential water demand to dynamic pricing: Evidence from an online experiment
Urban water demand management is key to water supply sustainability in high-density, water-stressed areas throughout the world, and emerging technologies could transform it. In particular, smart metering could allow for conserving water by dynamically changing prices to reflect water scarcity and supply cost variability. Yet, little is known on end-users’ reaction to short-term price changes, an essential determinant of the effectiveness and acceptability of dynamic water pricing. This paper reports on the design and results of an online experiment that measures end-users’ water consumption decisions when confronted with time-varying prices, and investigates the interaction between pricing and water scarcity awareness. We design a series of treatments where players must indicate their shower length given different water prices, price variations, and scarcity scenarios. Beyond corroborating the theory that higher prices lower usage, the experiment finds evidence of a dynamic pricing effect: users respond more strongly to a given price if they have been exposed to a lower price before. This suggests short-term residential price increases could be effective at boosting water conservation.
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.
