Elicitation Effects in Contingent Valuation: Comparisons to a Multiple Bounded Discrete Choice Approach
开发了一种多重有界离散选择诱导技术，让受访者对一系列投票阈值表达确定性程度，并通过实证比较发现该方法能覆盖三种标准诱导方法（二分选择、支付卡、开放式）的价值范围。
This paper develops a multiple bounded discrete choice elicitation technique that allows respondents to express their level of voting certainty for a wide range of referendum thresholds. The paper concludes with the results of an empirical study comparing values obtained from a multiple bounded model with values derived from three standard contingent valuation elicitation formats: dichotomous choice, payment card, and open-ended. The multiple bounded discrete choice format covers the range of values associated with the other three predominantly used elicitation methods. Moreover, alternative parameterizations of the multiple bounded discrete choice model correspond to these standard elicitation techniques.
