We present results from six randomized control trials of an integrated approach to improve livelihoods among the very poor. The approach combines the transfer of a productive asset with consumption support, training, and coaching plus savings encouragement and health education and/or services. Results from the implementation of the same basic program, adapted to a wide variety of geographic and institutional contexts and with multiple implementing partners, show statistically significant cost-effective impacts on consumption (fueled mostly by increases in self-employment income) and psychosocial status of the targeted households. The impact on the poor households lasted at least a year after all implementation ended. It is possible to make sustainable improvements in the economic status of the poor with a relatively short-term intervention.
我们介绍了六项随机对照试验的结果，这些试验采用综合方法改善赤贫人群的生计。该方法将生产性资产的转移与消费支持、培训和辅导相结合，同时鼓励储蓄以及提供健康教育和/或服务。对同一基本方案的实施结果进行了调整，以适应广泛的地理和制度背景，并由多个实施伙伴执行，结果表明，对消费（主要由自营职业收入的增加推动）和目标家庭的社会心理状况产生了具有统计学意义的成本效益影响。在所有实施工作结束至少一年后，这种影响仍持续存在于贫困家庭中。通过相对短期的干预，可以使贫困人口的经济状况得到可持续改善。
