Semiparametric hedonic price models: assessing the effects of agricultural nonpoint source pollution
比较了多种非参数和半参数特征价格模型，用于分析农业非点源污染对房价的非线性影响，发现集约化畜牧养殖污染对农村房价有显著非线性作用。
Abstract In the area of environmental analysis using hedonic price models, we investigate the performance of various nonparametric and semiparametric specifications. The proposed model specifications are made up of two parts: a linear component for house characteristics and a non‐(semi)parametric component representing the nonlinear influence of environmental indicators on house prices. We adopt a general‐to‐specific search procedure, based on recent specification tests comparing the proposed specifications with a fully nonparametric benchmark model, to select the best model specification. An application of these semiparametric models to rural districts indicates that pollution resulting from intensive livestock farming has a significant nonlinear impact on house prices.
