Abstract

The informal economy is often seen as marginalized and thought to aggravate the poverty situations of the agents within the sector. However, in sub–Saharan Africa, the informal economy is a dominant feature which can help reduce poverty, provided the sector is moderated by institutional quality, which is a knowledge gap. The study's novelty lies in the moderating effect of quality of institutions in the informal economy‐poverty debate. The paper uses cross‐country panel data from 41 sub‐Saharan African countries from 2005 to 2019 and the two‐step system generalized method of moments estimation technique. Principally, the results indicate that in both the short and the long run, improvement in the quality of institutions is not only crucial for poverty reduction but is also important in complementing informality to reduce poverty in sub‐Saharan Africa. 非正规经济通常被视为边缘化经济, 并被认为会加剧该部门从业人员的贫困状况。然而, 在撒哈拉以南非洲, 非正规经济是一个主导性特征, 如果该部门受到制度质量的调节 (而制度质量是目前知识的空白), 则有助于减少贫困。本研究的创新之处在于探讨了制度质量在非正规经济与贫困关系中的调节作用。本文使用2005年至2019年41个撒哈拉以南非洲国家的跨国面板数据, 并采用两步系统广义矩估计法(SGMM)进行估计。结果表明, 无论从短期还是长期来看, 提高制度质量不仅对减贫至关重要, 而且对于补充非正规经济以减少撒哈拉以南非洲的贫困也具有重要意义。 A menudo se percibe la economía informal como un sector marginado y se considera que agrava las situaciones de pobreza de los agentes que lo integran. Sin embargo, en el África subsahariana, la economía informal constituye un rasgo predominante que puede contribuir a reducir la pobreza, siempre y cuando el sector se vea moderado por la calidad institucional, aspecto que representa una laguna en el conocimiento actual. La originalidad de este estudio radica en el efecto moderador que ejerce la calidad de las instituciones en el debate sobre la relación entre la economía informal y la pobreza. El artículo emplea datos de panel de corte transversal de 41 países del África subsahariana, abarcando el periodo comprendido entre 2005 y 2019, y utiliza la técnica de estimación del método generalizado de momentos (MGM) en sistema de dos pasos. Fundamentalmente, los resultados indican que, tanto a corto como a largo plazo, la mejora en la calidad de las instituciones no solo resulta crucial para la reducción de la pobreza, sino que también desempeña un papel importante al complementar la informalidad con el fin de mitigar la pobreza en el África subsahariana.
