Can information about energy costs affect consumers’ choices? Evidence from a field experiment☆
通过在瑞士入户收集家电数据，向消费者提供定制化的节能省钱信息，发现该信息显著提升了新购家电的能效等级，且潜在节省金额越大，消费者选择越高效。
Whether consumers are fully informed and attentive when investing in energy efficiency is still hotly debated. We experimentally evaluate the role of imperfect information about or limited attention to energy costs in the demand for energy-consuming household durables in Switzerland. Using in-home visits, we collect unique data on the characteristics of participants’ current home appliances and light bulbs. Our intervention exploits this data to provide customized information about the potential of monetary savings from adopting new, comparable, and efficient durables. We find a substantial information treatment effect on the energy efficiency of the newly purchased durables. A larger potential of monetary savings induces larger durables choices responses. These findings provide suggestive evidence that the informational content of our intervention played a significant role in determining the observed durables choices responses.
