Why Has House Price Dispersion Gone Up?
构建空间动态均衡模型，发现生产率离散度上升导致美国都市区间房价离散度增加，模型匹配了30年数据。
We set up and solve a spatial, dynamic equilibrium model of the housing market based on two main assumptions: households with heterogenous abilities flow in and out metropolitan areas in response to local wage shocks, and the housing supply cannot adjust instantly because of regulatory constraints. In our equilibrium, house prices compensate for cross-sectional productivity differences. We increase productivity dispersion in the calibrated model in order to match the 30-year increase in cross-sectional wage dispersion that we document based on metropolitan-level data. We show that the model quantitatively matches the observed 30-year increase in dispersion of house prices across US metropolitan areas. It is consistent with several other features of the cross-sectional distribution of house prices and wages.
