Homelessness may be both a cause of and one of the more extreme outcomes of poverty. Governments at all levels and private organizations have a variety of tools to combat homelessness, and these strategies have changed dramatically over the past quarter century. In this paper, we catalog the policy responses and the existing literature on the effectiveness of these strategies, focusing on studies of individual‐level effects from randomized controlled trial evaluations and the best quasi‐experimental designs. We conclude by discussing outstanding questions that can be addressed with these same methods.

减少和预防无家可归的政策：我们在研究中所知道和存在的空白

无家可归可能是贫穷的原因，也是贫穷的更极端后果之一。各级政府和私人组织拥有各种手段来与无家可归者作斗争，这些战略在过去的25年中发生了巨大变化。在本文中，我们对政策对策和有关这些策略有效性的现有文献进行了分类，重点研究了来自随机对照试验评估和最佳拟实验设计的个体水平效应。最后，我们讨论可以用这些相同方法解决的悬而未决的问题。
