Achieving persistence in household behavior modification has been a central but elusive goal of environmental conservation attempts that rely on behavioral interventions. We implemented a habit change intervention, designed to achieve persistent change in household water conservation behavior in an affluent residential community in urban India. We found a 15 to 25% reduction in household water consumption in the absence of any volumetric pricing. Most importantly, the effects of our 5-wk intervention persisted for more than a year, after which marginal pricing was introduced. The treatment gap was not bridged even after a year under the marginal price regime.
实现家庭行为改变的持久性一直是依赖行为干预的环境保护努力的核心但难以实现的目标。我们实施了一项习惯改变干预措施，旨在实现印度城市一个富裕居民区家庭节约用水行为的持久改变。我们发现，在没有任何体积定价的情况下，家庭用水量减少了 15%至 25%。最重要的是，我们 5 周干预措施的效果在引入边际定价一年后仍持续存在。即使在边际价格制度下一年后，治疗差距仍未缩小。
