However, willingness to pay for a set of substitute and/or complement multiple goods evaluated by a double-bounded dichotomous choice will not only be affected by the offered bids of the goods being evaluated itself but also the offered bids provided for the goods being evaluated sequentially. As a result, if such effect is not taking into account the mean willingness to pay from a double-bounded dichotomous choice evaluation will be biased. The purpose of this study is to construct a model for correcting the starting point bias with the offered bids provided for certain good being evaluated and account for offered bids provided for the potential substitution and complementarity goods proposed beforehand. The empirical examination is then performed for three major risk factors of cardiovascular disease, in which these three factors are evaluated in a sequence and the information is released to respondents one at a time. The mean willingness to pay are computed and compared between the modified and unmodified models. The empirical evidence show that there exists a relationship between risk factors, i.e. these three factors can not be treated separated as if they were irrelevant. A strong anchoring effect results in overestimating the benefits of three major modifiable cardiovascular risk factors in unmodified model. Therefore, the model constructed in this study is an ideal model to estimate the mean willingness to pay for these three major factors in computing the total benefit of preventing the cardiovascular disease.口試委員審定書ⅰ　 謝辭　ⅱ 中文摘要ⅲ 英文摘要ⅳ 第一章 緒論 1 第一節 研究動機 1 第二節 研究目的 5 第二章 多財貨雙界二元選擇評估之起始點偏誤校正模型的建構 6 第一節 以支出差異詮釋雙界二元選擇評估模式 6 第二節 多財貨起始點偏誤校正模型之建構 8 一、僅考慮起始點偏誤之校正模型的建構 9 二、納入多財貨間相關性之起始點偏誤的模型建構 15 第三章 資料來源與變數選擇 25 第一節 資料來源 25 第二節 變數之選擇與處理 26 第四章 估計模型之設立與結果分析 35 第一節 起始點偏誤之初步檢測 35 第二節 願付價值估計模型之設立與估計方法 38 一、三危險因子之罹病風險的估計 38 二、未校正財貨相關性及起始點偏誤之三危險因子願付價值的估計39 三、未校正起始點偏誤但考量財貨相關性之三危險因子願付價值估計 42 四、僅校正起始點偏誤之三危險因子願付價值估計 44 五、考量財貨間相關性之多財貨起始點偏誤校正模型 46 六、各校正模型估計方法 51 第三節 估計結果分析 52 一、罹病風險機率之估計結果 53 二、三高危險因子願付價值之係數估計結果分析 53 三、三高危險因子願付價值及降低心血管疾病之總效益估算結果58 第五章 結論 62 第一節 結論 62 第二節 未來研究方向之建議 63 參考文獻 64 附錄：CVDFACTS部分問卷內容 68627493 bytesapplication/pdfen-US支出差異財貨替代互補個別評估依序評估資訊處理expenditure differencesubstitution and complementarity of goodindependent valuationsequential valuationinformation process[SDGs]SDG3thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/58990/1/ntu-96-R94627006-1.pdf
