详细说明
该项目将评估一种创新的、具有理论动机的经济干预措施，以减少男性参与性交易和其他危险行为。 利用移动金融服务的创新和对低收入国家储蓄行为的研究，研究人员提议测试一项干预措施，该干预措施旨在激励肯尼亚西部的高风险、赚取收入的男性减少他们在风险行为上的支出，而不是将他们的储蓄存起来。当地银行账户中的可支配收入。 这些银行账户将包括额外的储蓄激励措施，形式为与储蓄金额挂钩的彩票奖励。 干预还将鼓励参与者制定储蓄目标和策略，并定期提醒他们定期储蓄。 通过直接的经济机制（激励将支出从现在转移到未来）和心理机制（增加未来导向），研究人员假设干预将导致储蓄增加、性交易和酒精支出减少、性行为风险降低行为，并降低感染 HIV 和性传播感染 (STI) 的风险。
研究人员将在 HIV 和 STI 感染高风险男性中进行随机对照试验，并确定储蓄干预对健康和经济结果的影响。 该项目的具体目标如下。 目标 1：确定干预措施对储蓄和投资行为、自我报告的性行为以及 HIV/STI 发病率的影响。 目标 2：定量和定性地评估参与者及其女性伴侣样本中行为改变的机制。
