中文摘要
新一轮社会服务项目旨在通过帮助服务对象确定自身目标,并在多年间以灵活而密集的方式支持其实现这些目标,从而为其开辟一条脱贫路径。我们对其中一个此类项目——“通往成功之桥”(Bridges to Success)——开展了一项随机对照试验。两批参与者被随机分配至通常持续两年的密集型、整体性、一站式服务组,或分配至仅就当前迫切需求提供帮助的对照组。由于该干预措施具有明确的脱贫目标,同时又具有整体性,我们预先设定了就业结果与非就业结果两类指标。随机分组三年后,就业的处理效应估计值为9±9个百分点。一年后报告住房质量较高者所占比例的处理效应为−2±12个百分点。在探索性分析中,进一步证据表明,就业效应比非就业结果的效应更为有力。一年后的就业处理效应为10±8个百分点。将本研究数据与现有最相似研究的数据合并后,估计精度高于任一单项研究,结果表明此类项目可能产生适度的正向就业效应。另一方面,我们几乎没有发现密集型整体性服务会影响住房以外其他各类非就业结果的证据,即便生活的其他方面是参与者的首要目标。
Abstract
A new wave of social service programs aims to build a pathway out of poverty by helping clients define their own goals and then supporting them flexibly and intensively over multiple years to meet those goals. We conduct a randomized controlled trial of one such program, Bridges to Success. Two cohorts of participants were randomly assigned to intensive, holistic, wrap-around services that typically last two years versus a control offered help with an immediate need. Since the intervention has a clear goal of exiting poverty but is also holistic, we pre-specified both employment and non-employment outcomes. The measured treatment effect on employment three years after random assignment is 9 ± 9 percentage points (pp). The proportion of people reporting high housing quality after one year has a treatment effect of −2 ± 12 pp. In exploratory analysis, additional evidence suggests a stronger case for effects on employment than non-employment outcomes. Employment after one year shows a treatment effect of 10 ± 8 pp. Pooling our data with the most similar existing study increases precision relative to either study alone and indicates that such programs likely generate moderately positive employment effects. On the other hand, we find little evidence that intensive, holistic services affect any of a wide variety of other non-employment outcomes beyond housing, even when other areas of life are participants’ primary goals.
