Bayesian Downward Belief Revision of Infectious Risk
"A Bayesian updater, who initially overestimates HIV risk, is likely to revise beliefs downward as more people in his community learn their results because the vast majority learns they are HIV-negative."
Community Incentive and Distance Instrumental Variable Method
"We measure the causal effect of others' testing by utilizing an experiment that randomly offered incentives to individuals to learn their HIV test results at randomly located results centers."
Monetary Incentive and Travel Distance Elasticity in Health Result Acquisition
"After testing, respondents were offered randomly assigned monetary incentives to learn their HIV results ranging from zero to three dollars. Two months later the HIV test results were available at mobile counseling centers that were randomly located within the study sites."
Differential Belief Persistence Between Personal and Peer Health Information
"Thornton (2012) finds that learning HIV results has only short-term effects on subjective beliefs which do not persist after two years."
Private Utility vs. Public Health Externality Trade-Off
"From a strictly individual welfare-maximizing perspective, more accurate beliefs allows for optimal decisions, and in fact, for many whose risk of HIV is low, reduction of condom use may increase personal utility. However, given the negative externalities of HIV/AIDS, reductions in condom use could be a concern for social welfare."
Subjective Expected Utility Decision Making Under Diagnostic Uncertainty
"Savage (1954) advanced a theory that allows decision makers to maximize expected utility based on subjective probabilities of different states when objective probabilities are unknown."
