Preference reversals in Contingent and Inferred valuation methods
研究了条件估值法和推断估值法在食品市场中引发的偏好排序不一致，发现推断估值法更易出现弱不一致，且在高承诺成本下估值更高，但能减少社会期望偏差。
We examine inconsistencies in preference orderings using the Contingent valuation (CV) and the Inferred valuation (IV) methods. We find that in the context of a food market we do not observe strong inconsistencies. Weak inconsistencies are observed for the IV method, indicating that IV is slightly more susceptible to inconsistent preference orderings than the CV method. We also find that the IV method generates higher valuations than CV in the case of consumers with high commitment costs (that is, low familiarity with the product) but successfully mitigates social desirability bias in the case of low commitment costs and high normative motivations.
