An Alternative to the Standard Spatial Econometric Approaches in Hedonic House Price Models
指出标准空间计量方法在享乐房价模型中的局限性，并提出空间广义加性模型作为替代，发现参数估计对固定效应尺度和带宽敏感，反映了控制变量空间尺度未知时的不确定性。
Omitted, misspecified, or mismeasured spatially varying characteristics are a cause for concern in hedonic house price models. Spatial econometrics or spatial fixed effects have become popular ways of addressing these concerns. We discuss the limitations of standard spatial approaches to hedonic modeling and demonstrate the spatial generalized additive model as an alternative. Parameter estimates for several spatially varying regressors are shown to be sensitive to the scale of the fixed effects and bandwidth dimension used to control for omitted variables. This sensitivity reflects the uncertainty associated with the estimates when the appropriate spatial scale of the controls is unknown. <i></i>
