| dc.description.abstract | The purpose of this study is to estimate the value of Enterovirus 71 vaccine by contingent valuation method. We interview 600 parents who have the kids studying in kindergarten and live in Chungli and Pingchen areas to figure out their preference about Enterovirus 71. By using the payment card method, we discuss the factors that determine the respondents’ willingness to pay from the ordinary least square estimation. We also use the Chow’s test to check whether different type of questionnaire changes the parameter estimates. Furthermore, the differences of respondents’ WTP between high-prevention vaccine and low-prevention vaccine are discussed. Finally, we calculate the value of statistics life of kid through willingness to pay of vaccine.
The empirical result show that Enterovirus knowledge, kids under 6 years of age in the family, the youngest kid’s age and disease experience are negative to WTP; income, disease prevention level and health level are positive to WTP. The result of chow’s test shows that different type of questionnaire won’t change the result. The predicted mean value ranges from 3,448 to 3,515 NT dollars in one high-prevention vaccine; it is about 2,231 NT dollars in one low-prevention vaccine; about 1,204 to 1,372 NT dollars in five-dose high-prevention vaccine; and about 973 NT dollars in five-dose low-prevention vaccine. The empirical result in Tobit model also reveal that respondents who are high income, female, with an unhealthy kid will pay more to buy vaccine, and will pay higher amounts to buy high-prevention vaccine than low-prevention vaccine. Eventually, the predicted VSL is $0.4 to 1.08 million dollars.
