We employ provincial data from China on the incidence rate of AIDS between 2002 and 2008 to test the theoretical predictions. The findings are： （1） a rise in personal income/wealth induces more safe sexual activities and reduces the prevalence of AIDS; and （2） increases in public health expenditure do not have a significant positive impact on individuals＇ preference of risky sexual activity over safe sexual activity.展开更多
