Climate Amenities, Climate Change, and American Quality of Life
利用2000年人口普查和天气数据,估计美国家庭对当地气候的偏好,发现美国人偏爱日均65华氏度,且气候变化在2100年将导致年福利损失占收入的1%至4%。
We present a hedonic framework to estimate US households’ preferences over local climates, using detailed weather and 2000 Census data. We find that Americans favor a daily average temperature of 65 degrees Fahrenheit, that they will pay more on the margin to avoid excess heat than cold, and that damages increase less than linearly over extreme cold. These preferences vary by location due to sorting or adaptation. Changes in climate amenities under business-as-usual predictions imply annual welfare losses of 1%–4% of income by 2100, holding technology and preferences constant.
