Decomposing Variations in Quality of Life Through Amenities: Evidence From Korean Cities
利用韩国城市数据估计生活质量，发现首尔2019年生活质量高且持续上升，家庭更愿为密集、高学历、温暖的城市付费，人为便利设施解释了大部分城市间和随时间的生活质量变化。
ABSTRACT We estimate the quality of life (QOL) across Korean cities and decompose the cross‐sectional and temporal variations in QOL through amenities. Using administrative housing transaction data, a city's revealed‐preference QOL is estimated from its cost of living relative to its wage level. Seoul, the biggest city in Korea, had a significantly high QOL in 2019, and its QOL continuously increased from 2015 to 2019. Based on a hedonic framework, households are willing to pay more for denser, more educated, and warmer cities. Decomposing QOL using amenities chosen by LASSO, we find that a large portion of the cross‐sectional variation in QOL across cities is attributable to human‐made amenities. We also show that most temporal variation in QOL can be accounted for by amenities, particularly their increasing value.
