This paper examines the effects of learning HIV status on economic behavior among rural Malawians. According to economic life-cycle models, if learning HIV results is informative about additional years of life, being diagnosed HIV-positive or negative should predict changes in consumption, investment and savings behavior with important micro and macro-economic implications. Using an experiment that randomly assigned incentives to learn HIV results, I find that while learning HIV results had short term effects on subjective belief of HIV infection, these differences did not persist after two years. Consistent with this, there were relatively few differences two years later in savings, income, expenditures, and employment between those who learned and did not learn their status.
本文考察了了解艾滋病毒感染状况对马拉维农村居民经济行为的影响。根据经济生命周期模型,如果了解艾滋病毒感染状况能提供关于剩余寿命的信息,那么被诊断为艾滋病毒呈阳性或阴性应该会预示消费、投资和储蓄行为的变化,这具有重要的微观和宏观经济意义。通过一项随机分配激励措施以了解艾滋病毒检测结果的实验,我发现,虽然了解艾滋病毒检测结果对艾滋病毒感染的主观信念有短期影响,但两年后这些差异并未持续存在。与此一致的是,两年后,了解和未了解自身感染状况的人群在储蓄、收入、支出和就业方面的差异相对较少。
