The Spatial Proximity of Metropolitan Area Housing Submarkets
研究了住房子市场划分中地理区域是否必须空间相邻的问题，比较了两种划分方法（相邻与允许空间不连续）对特征价格预测准确性的影响。
An important question related to housing submarket construction is whether geographic areas must be spatially adjacent in order to be considered the same submarket. Housing consumers do not necessarily limit their search to spatially concentrated areas and may search similarly priced neighborhoods located throughout a metropolitan area when making housing consumption decisions. This article examines two alternative procedures for delineating submarkets: one that combines adjacent census block groups into areas with enough transactions to estimate the parameters of a hedonic house price equation and a second that permits spatial discontinuities in submarkets. The criterion used to evaluate the alternative techniques is the accuracy of hedonic house price predictions.
