A game of two halves? Incentive incompatibility, starting point bias and the bidding game contingent valuation method
研究了竞价博弈条件价值评估法是否同时存在激励不相容和起始点偏差问题，基于布基纳法索样本发现两种效应均存在，但平均支付意愿值在多变量分析中基本不受影响。
The bidding game (BG) method of contingent valuation is one way to increase the precision of willingness to pay (WTP) estimates relative to the single dichotomous choice approach. However, there is evidence that the method may lead to incentive incompatible responses and be associated with starting point bias. While previous studies in health using BGs test for starting point bias, none have also investigated incentive incompatibility. Using a sample of respondents resident in Burkina Faso, West Africa, this paper examines whether the BG method is associated with both incentive incompatibility and starting point bias. We find evidence for both effects. However, average WTP values remained largely unaffected after accounting for both factors in multivariate analyses. The results suggest that the BG method is an acceptable technique in settings where prices for goods are flexible.
