Abstract

Imperfect information and inattention to energy costs are important potential motivations for energy efficiency standards and subsidies. We evaluate these motivations in the lightbulb market using a theoretical model and two randomized experiments. We derive welfare effects as functions of reduced-form sufficient statistics capturing economic and psychological parameters, which we estimate using a novel within-subject information disclosure experiment. The main results suggest that moderate subsidies for energy-efficient lightbulbs may increase welfare, but informational and attentional biases alone do not justify a ban on incandescent lightbulbs. Our results and techniques generate broader methodological insights into welfare analysis with misoptimizing consumers. (JEL D12, D83, H21, H31, L67, Q41, Q48)
评估行为激励政策:来自灯泡市场的实验证据
信息不完善和对能源成本的忽视是制定能效标准和补贴的重要潜在动机。我们使用一个理论模型和两个随机实验来评估灯泡市场中的这些动机。我们将福利效应作为捕获经济和心理参数的简化形式充分统计的函数来推导,我们使用新颖的主题内信息披露实验来估计这些参数。主要结果表明,对节能灯泡的适度补贴可能会增加福利,但仅凭信息和注意力偏见并不能证明禁止使用白炽灯泡是合理的。我们的结果和技术产生了更广泛的方法见解与不当优化的消费者福利分析。(jel d12, d83, h21, h31, l67, q41, q48)
