本文研究了当根据过去的用电量提供电费账单信息时，人们对电费计划的态度的差异。我们对开放前后的电价选择进行了陈述偏好（SP）和揭示偏好（RP）的随机对照试验。在SP实验中，我们测量了参与者对其电价计划的估值。我们发现，提供有关参与者从转换中获益的信息可以减少过度自信的倾向。当资料显示转换会造成损失时，估值会大幅下降。RP和SP实验的结果不同。我们发现，在RP实验中，即使提供了会产生损失的信息，选择也没有改变。
This paper examines differences in attitudes towards electricity fee plans when information is provided on electricity bills based on past electricity consumption. We conducted randomized controlled trial stated preference (SP) and revealed preference (RP) experiments on the choice of electricity rates before and after liberalization. In the SP experiment, we measured participants' valuations of their electricity pricing plans. We found that providing information about the participants' benefit from switching diminished the tendency towards overconfidence. The valuation decreases substantially when information shows that a loss will be incurred from switching. The results of the RP and SP experiments differ. We found that the selection was not changed in the RP experiment even when providing information that a loss would be incurred.
