One thing leads to another: Evidence on the scope and persistence of behavioral spillovers
通过一项热水节约的自然田野实验，发现干预不仅减少了热水使用，还意外导致房间供暖能耗下降5.6%，且效果持续一年，对福利有重要影响。
Evaluations of economic interventions usually focus on one target behavior. This study extends the evaluation scope to multiple untargeted behaviors. We evaluate a hot water saving intervention in a natural field experiment. Despite an exclusive focus on hot water, the intervention changes multiple behaviors. Notably, we find a 5.6 percent reduction in room heating energy consumption that persists one year after the intervention. We show that the room heating spillover has important welfare implications.
