Savings allows households to smooth consumption and make investments. Savings also helps stabilize banking markets and fuel economic growth. Yet much remains unknown about the determinants of savings, particularly in developing countries. Are low savings a consequence of low access to safe, affordable savings product, or do households also need mechanisms designed specifically to help them commit to save?We are working with a rural bank in the Philippines to offer market-driven innovative savings devices with commitment features. The project employs a rigorous experimental research design, with random assignment to treatment and control groups, in order to draw robust policy conclusions about the potential implications for expansion of these client-responsive products on overall economic outcomes for poor, rural Filipinos. We will collect a full set of outcome variables so that we can measure not only changes in savings at the rural bank, but changes in aggregate household savings in both formal andinformal vehicles. Furthermore, we will collect consumption and investment data so that we can observe how additional savings were or were not used, and lastly we will conduct in depth analysis of who decides to take-up the commitment savings products so that we can try to disentangle competing theories of savings behavior.

储蓄使家庭能够平稳消费和进行投资。 储蓄还有助于稳定银行市场和推动经济增长。 然而，关于储蓄的决定因素，特别是在发展中国家，仍有许多未知之处。 储蓄低是因为难以获得安全、负担得起的储蓄产品，还是家庭也需要专门设计的机制来帮助他们储蓄？我们正与菲律宾的一家农村银行合作，提供具有承诺功能的市场驱动型创新储蓄工具。 该项目采用了严格的实验研究设计，随机分配给治疗组和对照组，以便就扩大这些响应客户需求的产品对菲律宾农村贫困人口的总体经济成果的潜在影响得出有力的政策结论。 我们将收集一整套结果变量，这样我们不仅可以测量农村银行储蓄的变化，还可以测量正式和非正式渠道的家庭总储蓄的变化。 此外，我们还将收集消费和投资数据，以便观察额外储蓄的使用情况和未使用情况。最后，我们将对决定购买承诺储蓄产品的人进行深入分析，以便尝试理清储蓄行为的竞争理论。
