Why we still don't know much about housing supply elasticity
从城市空间模型出发,理论分析住房供给弹性如何随城市规模、建筑成本、农村地价等因素变化,并指出规划管制和地形特征若均匀适用则不影响供给弹性,为实证研究提供理论指导。
Abstract This article examines the implications of urban spatial models for estimating the long‐run own‐price elasticity of housing supply. It demonstrates theoretically that housing supply elasticity varies inversely with city size, the cost of structure inputs, and rural land price in both classical and neoclassical models. Notably, planning regulations and topographic features that reduce the share of land available for development do not affect supply elasticity, if they apply uniformly. The effect of transportation costs on supply elasticity is complex. In addition, empirical estimates of supply elasticity depend on the location within the city where housing price changes are measured. These relations can confound direct empirical estimates of housing supply elasticity, but are less problematic for estimates obtained from numerical simulation models or inferred from urban wage premiums.
