Response to Extreme Energy Price Changes: Evidence from Ukraine
研究了乌克兰2013-2016年天然气和电价大幅上涨（最高达300%）对家庭电力需求的影响，发现短期价格弹性约为-0.3，且弹性在价格变化后三个月内增强50%，但关注消费或账单的用户反应并不更敏感。
Large but temporary price increases are sometimes deployed on days when the demand for electricity is extremely high due to exceptionally warm or cold weather. But what happens when the extreme price changes are permanent? Between January 2013 and April 2016, natural gas and electricity prices in Ukraine increased dramatically (up to 300% of the initial rates). We exploit variation in tariffs over time and across customers to estimate the price elasticity of electricity demand using a panel dataset with monthly meter readings from households in Uzhhorod in Ukraine. The price elasticity of electricity demand is -0.2 to -0.5, with the bulk of our estimates around -0.3. The elasticity becomes up to 50% more pronounced over the first three months since prices change. We find only limited evidence that persons who are attentive about their consumption levels, their bills, or the tariffs are more responsive to the price changes.
