Land Values in a Newly Zoned City
利用1923年芝加哥新分区条例作为自然实验，控制初始用途和分区内生性后，发现住宅分区比商业分区带来更高的土地价值增长率。
The introduction of a new zoning ordinance to Chicago in 1923 offers a natural experiment that allows us to determine the effects of zoning on relative land-value growth rates. Policymakers claimed at the time that land-use zoning would raise aggregate land values by reducing negative externalities associated with mixed land use. After controlling for initial land use and the endogeneity of zoning decisions, we find that residential zoning led to higher land value growth rates than commercial zoning. © 2002 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
