Abstract

This study was an investigation of the utility of behavioral economic demand curves (quantitative models showing how consumption changes with price) in assessing acceptance of hypothetical HIV vaccines among sexual and gender minorities (SGMs). Two experiments used simulated purchase tasks (hypothetical scenarios measuring purchasing decisions). SGMs were recruited through Reddit and LGBTQ+ community organizations across the United States. In Experiment 1, participants were randomly assigned to nine instructional sets combining varying vaccine administration modes (oral, mucosal, or subcutaneous) with different dosage schedules (one dose, two doses, or one dose annually). Experiment 2 examined how bundling HIV vaccines with one of nine health commodities affected demand. Participants also responded to questions assessing demographics, HIV risk behaviors, experiences of racial discrimination, and trust in institutions. The results demonstrated that the exponentiated demand equation effectively modeled vaccine acceptance across conditions (median R2 = 0.92). Contrary to expectations, vaccine characteristics had a minimal influence on demand (Q₀: R2 = 0.007; log α: R2 = 0.001). Instead, individual factors significantly influenced demand intensity (consumption when price = 0; Q₀) and price sensitivity (sensitivity of consumption to increasing price; α). Significant predictors of Q₀ included injection drug use history, experiences of racial discrimination, and trust in science. Low household income was the strongest predictor of log α. Bundling HIV vaccines with other health commodities showed subtle effects on acceptance, with condoms and dental examinations significantly differing from the reference category. These findings suggest that behavioral economic approaches can inform policy decisions about pricing, bundling strategies and targeted interventions to maximize HIV vaccine uptake among SGMs who face disproportionate HIV risk without requiring exposure to non-market-ready vaccines.

超越注射:用行为经济需求模拟性和性别少数群体接受艾滋病毒疫苗的情况
这项研究是对行为经济需求曲线(显示消费如何随价格变化的定量模型)在评估性少数群体和性别少数群体(SGMs)对假设的艾滋病毒疫苗的接受度方面的效用的调查。两个实验使用了模拟的购买任务(测量购买决策的假设场景)。sgm是通过美国各地的Reddit和LGBTQ+社区组织招募的。在实验1中,参与者被随机分配到9个教学组,这些教学组结合了不同的疫苗给药模式(口服、粘膜或皮下注射)和不同的剂量计划(一次剂量、两次剂量或每年一次剂量)。实验2考察了将艾滋病毒疫苗与九种保健商品中的一种捆绑在一起如何影响需求。参与者还回答了评估人口统计、艾滋病毒风险行为、种族歧视经历和对机构信任的问题。结果表明,指数需求方程有效地模拟了不同条件下的疫苗接受度(中位数R2 = 0.92)。与预期相反,疫苗特性对需求的影响最小(Q 0: R2 = 0.007;log α: R2 = 0.001)。相反,个体因素显著影响需求强度(价格= 0时的消费;Q 0)和价格敏感性(消费对价格上涨的敏感性;α)。Q 0的显著预测因子包括注射用药史、种族歧视经历和对科学的信任。低家庭收入是log α的最强预测因子。将艾滋病毒疫苗与其他保健商品捆绑在一起对接受度产生了微妙的影响,避孕套和牙科检查与参考类别有很大不同。这些发现表明,行为经济学方法可以为有关定价、捆绑策略和有针对性干预措施的政策决策提供信息,以便在不需要接触非市场准备疫苗的情况下,最大限度地使面临不成比例艾滋病毒风险的SGMs接种艾滋病毒疫苗。
