Major Reforms in Electricity Pricing: Evidence from a Quasi-Experiment
利用西班牙电价改革数据，通过准实验发现消费者无法区分固定成本和边际成本，导致政策制定者未能实现成本回收目标。
Abstract The global energy mix and cost structure of the power industry are experiencing a redefinition. Many countries are revamping electricity-pricing systems to guarantee fixed-cost recovery, often by raising the fixed charge of two-part tariff schemes. However, a key assumption of two-part tariff schemes and associated fixed-cost recoveries is that consumers discriminate fixed from marginal costs. We conduct a quasi-experiment with data from a major electricity price reform recently implemented in Spain and find robust evidence indicating that consumers fail to distinguish between fixed and marginal costs. As a result, policymakers are not achieving the goal of cost recovery.
