正确理解贫困陷阱-定义为由于穷人的平衡行为而自我强化的贫困-及其基本机制，对于制定旨在帮助穷人的政策和干预措施至关重要。我们回顾了宏观、中观、特别是微观层面上的单一均衡和多重均衡贫困陷阱的理论和经验证据。此外，我们回顾了文献探索的各种机制，已被假定为永久贫困。我们发现足够的证据支持贫困陷阱假说，这表明，旨在中断这些自我延续的机制值得认真关注的政策。
A sound understanding of poverty traps-defined as poverty that is self-reinforcing due to the poor's equilibrium behaviors-and their underlying mechanisms is fundamentally important to the development of policies and interventions targeted to assist the poor. We review the theoretical and empirical evidence on single equilibrium and multiple equilibria poverty traps at the macro-, meso-, and, especially, microlevels. In addition we review the literature exploring the various mechanisms that have been posited to perpetuate poverty. We find sufficient evidence to support the poverty traps hypothesis, suggesting that policies designed to interrupt those self-perpetuating mechanisms merit serious attention.
