基于行为经济学的干预措施正在成为帮助个人实现自己目标的强大工具，包括减肥。存款合同激励系统让参与者有机会把钱放在减肥上，如果他们减肥失败，他们就失去了这个机会;彩票激励系统让参与者在达到减肥目标时赢钱。在本文中，我们汇集了两项先前研究的数据，以研究这些研究中未发表的数据使我们能够解决的各种问题。首先，更深入地检查来自存款合同处理的数据，我们调查影响存款频率和规模的因素，并讨论增加存款的可能方法。接下来，我们比较了存款合同和彩票干预的有效性，作为参与者人口统计学特征的函数。这些观察结果可能有助于指导未来长期行为经济干预措施的设计。(C)2012 Elsevier Inc.

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 In this paper, we pool data from two prior studies to examine a variety of issues that unpublished data from those studies allow us to address.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. (C) 2012 Elsevier Inc. All rights reserved.
