How Strong is the Evidence for the Existence of Poverty Traps? A Multicountry Assessment
利用六个国家八套面板数据，检验资产动态与贫困陷阱的关系，发现长期贫困家庭资产水平较低，但未找到支持多重动态贫困陷阱的非凸性证据。
Introducing this special collection on asset dynamics and poverty traps, this article assesses evidence on these issues across eight panel data sets in six countries generally not previously considered in this perspective. It examines the importance of assets in relation to chronic poverty and uses parametric and non-parametric methods to test for dynamic asset-based poverty traps. The article finds that chronically poor households have lower levels of assets than others, though does not find evidence of the non-convexities which would imply a multiple dynamic poverty trap. From this base the article introduces the remainder of the articles in this collection which set out many promising approaches to further develop and improve methods and approaches for looking at poverty traps in future.
