Convergent Validity of Satellite and Secchi Disk Measures of Water Clarity in Hedonic Models
研究对比了卫星遥感和传统塞氏盘法测量的水质透明度在享乐价格模型中的表现,发现卫星数据对房价的统计拟合更强,且隐含价格高出11%。
Budget-constrained environmental agencies across the United States are limited in their ability to monitor water quality changes using traditional in situ sampling. Satellite-based monitoring systems represent a lower-cost alternative. It is unclear, however, how this transition will impact nonmarket valuation estimates of perceived water quality. To answer this question, we merge housing information with Secchi depth and satellite estimates of water clarity from over 100 lakes in Wisconsin. A comparison of hedonic price functions reveals satellite estimates of water clarity provide a stronger statistical fit of housing price and produce implicit prices up to 11% larger in magnitude.
