Abstract
Intervention policies for HIV/AIDS differ in their approaches, and acceptability to control the spread of the epidemics. We introduce a theoretical model to depict how several factors may determine an individual's maximum willingness to pay for any HIV/AIDS policy. Heterogeneous baseline risks, through risky sexual activities, operate so that those individuals with higher exposure to risky activities are inclined to pay for any policy that reduces the risk. However, given the epidemiological and economic context of a geographic region, the perceived effectiveness of a policy implies that it will reach some level of risk reduction outcome and then, not contribute any further to the control of epidemics. What comes into play is whether individuals observe the risk change generated by the policy and implications for behavioral changes. Finally, we also introduce altruistic motives as a determinant of the WTP.
期刊介绍：
The Economic Bulletin is an open-access letters journal founded in 2001 with the mission of providing free and extremely rapid scientific communication across the entire community of research economists. EB publishes original notes, comments, and preliminary results. We are especially interested in publishingmanuscripts that keep the profession informed about on-going research programs. Our publication standard is that a manuscript be original, correct and of interest to a specialist. Submissions in these categories are refereed and our objective is to make a decision within two months. Accepted papers are published immediately. It is expected that in many cases, manuscripts published in these categories will form the foundation for more complete works to besubsequently submitted to other journals. In all cases, submissions are restricted to seven printed pages exclusive of references, tables, figures, and appendices, and must be in PDF format. EB also publishes non-refereed letters to the editor, conference announcements and research announcements.
