Mortality Risk Information, Survival Expectations and Sexual Behaviours
研究随机提供人口死亡率信息对高风险HIV环境下个体健康投资和主观健康预期的影响，发现干预一年后不安全性行为减少，如禁欲率提高8%。
Abstract We investigate the impact of a randomised information intervention about population-level mortality on health investment and subjective health expectations. Our focus is on risky sex in a high-HIV-prevalence environment. Treated individuals are less likely to engage in risky sexual practices one year after the intervention, with, for example, an 8% increase in abstinence. We collected detailed data on individuals’ subjective expectations about their own and population survival, as well as other important health outcomes. Our findings emphasise the significance of integrating subjective expectation data in field experiments to identify the pathways that lead to behavioural change.
