Are consumers attentive to local energy costs? Evidence from the appliance market

中文摘要
我们估计消费者在购买家电时是否会对当地能源成本作出反应。利用来自一家家电零售商的数据集,我们将需求对随当地能源价格而变化的能源成本指标的反应,与需求对购买价格的反应进行比较。在广泛的假设条件下,我们无法拒绝如下假设:消费者对寿命期能源成本的反应方式与其对购买价格的反应方式相同。这些发现与一种流行观念相悖,即由于各种行为现象,能源成本被系统性低估——这正是能源标准得以推行的动因。这些发现意味着,当电价因未能纳入污染外部性或因费率设计中的其他特征而偏离社会边际成本时,可能对需求产生相当大的扭曲效应。
Abstract
We estimate whether consumers respond to local energy costs when purchasing appliances. Using a dataset from an appliance retailer, we compare demand responsiveness to a measure of energy costs that varies with local energy prices versus purchase prices. We cannot reject that consumers respond to lifetime energy costs in the same way they respond to purchase prices under a wide range of assumptions. These findings run counter to the popular wisdom, which motivates energy standards, that energy costs are systematically undervalued due to various behavioral phenomena. They imply that electricity pricing that deviates from social marginal costs, due to failure to incorporate pollution externalities or due to other features in rate design, can have substantial distortionary effects on demand.
