HIV/AIDS Contamination Risk, Savings and the Welfare Effects of Diagnostic Testing
AbstractThis paper models the effect of a HIV/AIDS epidemic on saving behavior and studies the welfare effects of testing for HIV. The model specifies a utility function that includes both regular consumption, and medical expenditures. Medical expenditures generate more utility if individuals are HIV infected, but they are only able to purchase the optimal medical consumption after being tested HIV positive. The paper describes different effects on aggregate savings according to different stages of the epidemic. We show that the HIV epidemic decreases savings if especially young individuals are (perceived to be) affected by the virus, but may increase savings if individuals perceive a sizable probability of getting infected later in life. By the same token, the welfare effects of testing young individuals differs greatly from the welfare effects of testing older individuals, the reason being that the savings responses to testing differ according to whether old or young individuals are tested.
