近年來在運用雙界二分選擇法(double-bounded dichotomous choice elicitation method)來估計受訪者願付價格(willingness to pay)的研究中，不再僅局限於單一非市場財貨的探討。這類型的模型中雖然納入了相關性的考量，但並未考慮財貨的願付價格間可能存在明確的大小關係。再者，針對抗議性樣本，以往的作法多半是丟棄不用，然而這顯然不是理想的作法。本文中，我們將建構一個模型來同時探討這兩項議題。此外我們也利用「竹東及朴子地區心臟血管疾病長期追蹤研究」第五循環中「肥胖之願付價格」的資料來進行實證分析。結果顯示，居住於竹東、有工作、曾以特定活動控制體重的受訪者願意支付較高的金額來參加減肥療程。 / Recent studies on estimating WTP prices in terms of the double-bounded dichotomous choice elicitation method are no longer restricted to the situations that discuss only one non-market good. Although a couple of models have been proposed to take the correlations into consideration when multiple scenarios are presented to the respondents, none of them pay attention to the possibilities that the prices themselves might be inherently ordered. This is one of the issues that need to be addressed. Another is about the protest samples. A common but apparently problematic approach is simply ignoring them completely. In this study, we propose a model that is able to take care of both issues simultaneously. In addition, the model is used to estimate WTP values for data collected in CVDFACTS about two weight loss treatments. The results indicate that respondents residing in Chu-Dong County, employed, and ever tried any weight controlled programs are willing to pay a higher price for the new treatments.
