Perception of Price When Price Information Is Costly: Evidence from Residential Electricity Demand
研究居民用电中，由于阶梯电价导致边际价格难以确定，消费者实际感知的是平均价格而非边际价格，并通过实证支持这一假设。
A bstract-Residential electricity consumption is an example of a good for which it is costly to determine marginal price, since price changes with the quantity purchased according to multistep block rate schedules. This paper investigates the effect of the price information problem on consumers' price perceptions. An alternative hypothesis of average price perception is tested against the marginal price postulate which assumes wellinformed consumers. The model, which includes a price perception variable, allows the estimation of the price to which consumers actually respond. The empirical results support the hypothesis that consumers respond to average price perceived from the electricity bill.
