我们的研究调查了住宅能源效率审计项目对后期家庭用电量的影响程度。这些项目旨在通过个性化的反馈来提高人们对家庭能源消耗的认识,最终导致行为的改变。在这种类型的调查中,自愿参与的住户与调查者之间只有一次互动。这项研究的目的是确定这些调查是否以及在多大程度上导致行为改变。我们认为,调查反馈的感知复杂性将决定后续行为是否可持续。然后,我们分析干预的持久性,以及影响是减弱还是增强。然而,这些调查的主要评价问题是自我选择偏差。为了纠正这种偏差,我们使用基于核的倾向评分匹配方法提出了两个非参数估计器。在第一种方法中,我们使用“差异-无差异”(DID)估计。第二个估计器是分位数DID,它产生对分布的估计。 The comparison group consists of households who were not yet participating in the survey but participated later. The evidence suggest that the customers who participated in the survey reduced their electricity consumption by 6.7%, compared with customers who had not yet participated in the survey. In addition, as the quantiles of the distribution increase, the effect of the program decreases.
