Unformatted text preview: and 1989, Boozer and Philipson (2000) find asymmetric results: those who thought they were at risk and were diagnosed HIV-negative reported increased sexual contact by 20 percent; those who thought they were not at risk but were diagnosed HIV-positive reported decreasing sexual contact by 50 percent. Their findings give important theoretical insights into who benefits from the information provided by HIV testing and potential asymmetric behavior among those with differing prior beliefs of HIV status. Using the same measure of likelihood of infection as Boozer and Philipson, I find no significant relationship between prior beliefs and condom purchases. Table 11 presents the impact of learning HIV results on condom purchases among those who had sex at the baseline, including an indicator of whether the respondent believed there was any likelihood of being infected, as well as an interaction of respondent prior beliefs with learning HIV status.20 Each specification is presented separately for HIV-positives and HIV-negatives. In 20 Likelihood of HIV infection is coded as “one” if the respondent replied there was any chance of being infected or if she did not know. Likelihood of HIV infection is coded as “zero” if she reported no likelihood of infection (see also Table 10, column 1). Results do not change if those reporting “don’t know” are coded as “zero” or if they are omitted. 1856 DEcEMBER 2008 THE AMERIcAN EcONOMIc REVIEW Table 11—Interaction of Prior Belief of Infection and Condom Purchases (Dependent variable: purchased any condoms) 0.484** 1 0.1972 HIV-positive OLS (1) Got results Got results 3 likely to be infected Likely to be infected Constant Sample size R2 p-statistic (got results 1 got results 3 likely to be infected 5 0) 20.064 1 0.2372 0.072 1 0.124 2 0.000 1 0.844 2 52 0.21 0.03 IV (2) 0.535 20.36 20.421 20.399 0.274 20.262 0.389 21.059 52 0.15 0.69 20.048 1 0.030 2 0.054 1 0.0412 20.107 1 0.083 2 0.068 1 0.104 2 956 0.19 0.87 956 0.19 0...
