Zoning, Nonconvexities, and T. Jack Foster′s City
重新审视Crone（1983）对加州福斯特市样本的研究，指出其发现的分区效率证据实际上支持大规模私人开发而非公共分区的效率。
In a 1983 article in this Journal, Theodore Crone (Journal of Urban Economics, 14, 184–205, 1983) used a sample from Foster City, California, to test for nonconvexities, the presence of which he correctly argued is the basis for the efficiency rationale for municipal zoning. Foster City, however, was privately developed by a single landowner. The apparently value-maximizing configuration of homes and apartments that Crone found is not evidence against the efficiency of zoning, but evidence in favor of the efficiency of large-scale private development.
