Using Contingent-Pricing Analysis to Value Open Space and Its Duration at Residential Locations
融合条件估值和联合分析，提出条件定价框架，直接测量人们对住宅附近开放空间的支付意愿，发现短期开放空间无价值，而永久保护的空间可增加约5%的房价。
<i>To estimate benefits from open space adjacent to residences, this paper blends contingent valuation and conjoint analysis within a housing market context. The resulting framework — “contingent-pricing analysis,” — represents the stated preference counterpart to hedonic-pricing analysis by asking individuals to state prices for hypothetical housing locations, which include an environmental amenity. Then, it asks individuals to state their willingness to pay for a better and longer lasting environmental amenity. As an advantage over hedonic-pricing analysis, it directly isolates willingness to pay. Results indicate that potentially short-lasting open space adds no value, while preserved open space adds $ 5,066 or 5% to housing value.</i>
