本研究係利用Contingent Valuation Method (CVM),以問卷方式詢問民眾對環境風險降低的願付金額。研究中的環境風險區分成空氣污染與水污染兩種污染源所引發的肺部器官與肝器官疾病,風險程度區 分成慢性與急性病症,另外,疾病類型區分成癌症與非癌症。在願付金額部份,問卷中採用Double Bounded Discrete Choice方式,問卷中隨機設定金額(分別是台幣50元、100元、300元與500元),若受訪者照答願意支付,則調高一倍金額繼續詢問受訪者願不願 意支付;相反地,若受訪者在第一次回答不願意支付,則將金額減半,繼續詢問受訪者願不願意支付。實證結果發現避免空氣污染所造成的肺部器官疾病的願付金額 遠高於飲用水污染所引發的肝部器官疾病,而避免癌症的願付金額高於非癌症疾病,至於急性病症與慢性病症的願付金額並沒有明顯差異。

We evaluate the effects of disease type and latency on own willingness to pay (WTP) to reduce environmental risks of chronic, degenerative disease. Contingent-valuation data were collected from approximately 1,250 respondents in Taiwan. These data suggest the existence of a ancer premium:” WTP to reduce risk of cancer is estimated to be about 30 percent larger than WTP to reduce risk of a similar chronic degenerative disease. The value of risk reduction also depends on the affected organ, environmental pathway, or payment mechanism: WTP to reduce risk of lung disease due to industrial air pollution is estimated to be twice as large as WTP to reduce risk of liver disease due to contaminated drinking water. Finally, we find that WTP is insensitive to the latency period between exposure to environmental contaminants and manifestation of disease. This insensitivity suggests that respondents anticipate their value per statistical life will grow over time at a rate about equal to their discount rate
