Rural poverty dynamics: development policy implications
区分了长期贫困和暂时性贫困，探讨了贫困陷阱的存在及其对“货网”政策（积累生产性资产）和“安全网”政策（保护资产）的启示，并以撒哈拉以南非洲的实证为例。
Abstract This article explores the useful distinction between chronic and transitory poverty in understanding rural welfare dynamics, highlighting the possibility of poverty traps and their implications for “cargo net” policies to build up productive assets and “safety net” policies to protect such assets. We discuss the methodological difficulties in identifying and explaining either poverty traps or the critical thresholds that are their defining feature. A few empirical examples from sub‐Saharan Africa illustrate the likely existence of poverty traps that help to explain chronic rural poverty.
