摘要

目的验证非正式性与贫困关系中的阈值理论。最近的文献和政策都认为这种关系中存在一个门槛。设计/方法/方法本研究采用动态面板阈值分析,在系统广义矩量法(SGMM)框架内估计,以控制内生性和同时性。该研究使用了1991年至2018年40个撒哈拉以南非洲国家的数据。实证结果证实,存在一个平均阈值,即非正规行为占GDP的比例为31%。此外,本文还发现,解决轻度和重度贫困的非正式性阈值在24.32和36.75%之间。研究局限/启示这项工作仅限于非洲经济体。来自其他新兴和发达经济体的证据可供进一步研究。总体而言,实证结果表明了非正式性与贫困关系的阈值。因此,过度的非正式性水平不利于非洲的增长进程。建议政策制定者和政府在减少贫困和改善非洲经济增长进程的非正式门槛范围内开展工作。据作者所知,这篇论文是第一个对非正式性与贫困关系中的非线性和阈值论点提供实证结果的研究。

What levels of informality tackle poverty in Africa? Evidence from dynamic panel threshold analysis
PurposeThe paper validates the threshold argument in the informality–poverty nexus. Recent literature and policy have argued the existence of a threshold in the relationship.Design/methodology/approachThe study adopts dynamic panel threshold analysis, estimated within the framework of system Generalized Method of Moments (SGMM) to control for endogeneity and simultaneity. Data from 40 selected sub-Saharan African countries between 1991 and 2018 are used for the study.FindingsEmpirical results confirm the existence of an average threshold of 31% share of informality in GDP. Also, the paper finds that threshold of informality that addresses mild and severe poverty varies between 24.32 and 36.75%.Research limitations/implicationsThe work is limited to African economies. Evidence from other emerging and developed economies is suggested for further research.Practical implicationsOverall, the empirical results indicate a threshold in the informality–poverty nexus. Therefore, an excessive informality level does not benefit the African growth process. Policymakers and governments are advised to operate within the bounds of the threshold of informality that reduces poverty and improve the African economic growth process.Originality/valueThe paper is the first study to provide empirical findings on the nonlinear and threshold argument in the informality–poverty nexus, as far as the authors know.
