Incentive Incompatibility and Starting-Point Bias in Iterative Valuation Questions
研究了迭代估值问题中激励不兼容和起始点偏差对支付意愿估计的影响,发现两种偏差均存在且会扭曲估计结果,对从事环境价值评估的研究者具有参考价值。
<i>We test for incentive incompatibility and starting-point bias to describe the effects of iterative valuation questions on willingness to pay. We compare double-, triple-, and multiple-bounded models with data from two surveys with similar designs of the valuation questions. We find that incentive incompatibility is present in both sets of data and starting-point bias is present in one. The efficiency of the willingness-to-pay estimate is improved in only one set of data. The potential loss from using iterative questions without controlling for both incentive incompatibility and starting-point bias is biased willingness-to-pay estimates.</i>
