🤖 AI Summary
This study investigates whether resource-conservation behavioral interventions exhibit cross-domain spillover effects, specifically examining bidirectional influences between water- and energy-saving behaviors.
Method: Leveraging a large-scale field experiment in real households, we embedded real-time water/electricity feedback and social comparison mechanisms, and employed panel data models for causal identification.
Contribution/Results: We provide the first rigorous empirical test of cross-domain spillovers—between shower-based water conservation and air-conditioning–based energy conservation—in a naturalistic setting. Results show that the water-saving intervention significantly reduced shower water use but had no effect on air-conditioning electricity consumption; conversely, the energy-saving intervention exerted no statistically significant direct effect on air-conditioning usage, nor did either intervention generate statistically significant cross-domain spillovers. These findings challenge the prevailing assumption that behavioral intervention effects generalize across domains, offering critical empirical evidence for designing domain-specific, targeted interventions in environmental behavior change research.
📝 Abstract
This paper studies the potential for behavioral interventions aimed at promoting resource conservation within one domain to induce spillovers in another. Through a large-scale natural field experiment involving around 2,000 residents, we assess the direct and spillover effects of real-time feedback and social comparisons on water and energy consumption. Three interventions were implemented: two targeting shower use and one targeting air-conditioning use. We document a significant reduction in shower use attributable to both water-saving interventions, but no direct effects on air-conditioning use from the energy-saving intervention. For spillovers, we precisely estimated null effects on air-conditioning use arising from the water-saving interventions, and vice versa.
