Urban growth and housing supply
指出城市是物理结构，但现代城市经济文献很少承认这一点。住房供给弹性决定了生产力提升是导致城市规模扩大，还是仅提高工资和房价。模型和实证分析表明，住房供给的空间差异不仅推高房价，还影响城市对生产力增长的反应。
Cities are physical structures, but the modern literature on urban economic development rarely acknowledges that fact. The elasticity of housing supply helps determine the extent to which increases in productivity will create bigger cities or just higher paid workers and more expensive homes. In this article, we present a simple model that provides a framework for doing empirical work that integrates the heterogeneity of housing supply into urban development. Empirical analysis yields results consistent with the implications of the model that differences in the nature of house supply across space are not only responsible for higher housing prices, but also affect how cities respond to increases in productivity.
