| dc.description.abstract | This study explored the issue of public support for the provision of a “oneyear, free HIV vaccination programme”. Of all the contingent the valuation method (CVM) studies, this study has led the way in estimating how much the public, the general population, would be willing to pay for supporting this free scheme, targeting only commercial sex workers (CSWs), with a “one-off” payment as part of their yearly income tax. Thailand now faces a changing pattern of HIV/AIDS transmission into low risk groups, as a result of their direct and indirect contact with either male or female CSWs. This free scheme would be regarded as public good as it would reduce the risk of HIV/AIDS infection and prevalence among individuals in society, if an HIV/AIDS vaccine existed. With the use of a double bounded CVM format followed by an open-ended question, a 600-split sample survey study asked 20-60 year old taxpayers in Bangkok to elicit their willingness to pay (WTP) to support this scheme using either a 30% or 70% effective vaccine with an initial tax payment of either 500, 1,500, 2,000, 3,500, 5,000, or 6,000 baht. The study not only pioneered technique of a “storyboard” to guard against misspecification bias, but also applied “cheap talk scripts” to eliminate hypothetical bias during the interview. As for the measure of total economic benefit, the study divided respondents into “beneficiary” and “non-beneficiary” based on their responses to the questions about their sexual behavior. The results of the probit model found that the mean WTP values for a vaccine with 70% effectiveness were 2,515 and 2,050 baht as for single and double bounded format estimates, while a vaccine with 30% effectiveness had a mean WTP of 2,147 baht and 1,746 baht respectively. Personal income and the rate of tax payment were the most influential factors when individuals made their decisions on whether to sponsor this scheme. The study recommends that the Thai government should use a progressive tax to fund this scheme when a vaccine becomes available. It also suggests that the condom use campaign should be relaunched, along with the provision of more information about HIV/AIDS, to help halt this infectious disease. | th |
