Behavioral economic-based interventions are emerging as powerful tools to help individuals accomplish their own goals, including weight loss. Deposit contract incentive systems give participants the opportunity to put their money down toward losing weight, which they forfeit if they fail to lose weight; lottery incentive systems enable participants to win money if they attain weight loss goals. In this paper, we pool data from two prior studies to examine a variety of issues that unpublished data from those studies allow us to address. First, examining data from the deposit contract treatments in greater depth, we investigate factors affecting deposit frequency and size, and discuss possible ways of increasing deposits. Next, we compare the effectiveness of both deposit contract and lottery interventions as a function of participant demographic characteristics. These observations may help to guide the design of future, longer-term, behavioral economic-based interventions.
基于行为经济学的干预措施正在成为帮助个人实现自身目标的有力工具，包括减肥。存款合同激励系统为参与者提供了一个机会，让他们把钱投入到减肥中，如果他们未能减肥，就会失去这笔钱；彩票激励系统则使参与者如果达到减肥目标就能赢得奖金。在本文中，我们汇集了两项先前研究的数据，以研究这些研究的未发表数据使我们能够解决的各种问题。首先，我们更深入地研究存款合同治疗的数据，调查影响存款频率和金额的因素，并讨论增加存款的可能方法。接下来，我们比较存款合同和彩票干预作为参与者人口统计学特征的函数的有效性。这些观察结果可能有助于指导未来更长期的基于行为经济学的干预措施的设计。
