Preference Uncertainty in Non‐Market Valuation: A Fuzzy Approach
提出用模糊逻辑替代概率论来处理非市场商品估值中的偏好不确定性，将效用视为模糊数，并以瑞典森林估值数据展示该方法能提供比标准概率方法更丰富的资源价值估计。
Abstract In this article, we consider uncertain preferences for non‐market goods, but we move away from a probabilistic representation of uncertainty and propose the use of fuzzy contingent valuation. We assume that a decision maker never fully knows her own utility function and we treat utility as a fuzzy number. The methodology is illustrated using data on forest valuation in Sweden. Fuzzy contingent valuation provides estimates of resource value in the form of a fuzzy number and includes estimates obtained using a standard probabilistic approach.
