Electricity Consumption and Durable Housing: Understanding Cohort Effects
研究发现，加州1960-70年代建造的房屋在2000年电力消费较高，因当时电价低；而1990年代初建造的房屋因电价高而消费较低。建房时电价弹性为-0.22，随着老旧房屋占比下降，平均家庭用电量将减少。
We find that households living in California homes built in the 1960s and 1970s had high electricity consumption in 2000 relative to houses of more recent vintages because the price of electricity at the time of home construction was low. Homes built in the early 1990s had lower electricity consumption than homes of earlier vintages because the price of electricity was higher. The elasticity of the price of electricity at the time of construction was -0.22. As homes built between 1960 and 1989 become a smaller share of the housing stock, average household electricity purchases will fall.
