Shadow economy-income inequality nexus: a panel analysis of West African countries

This paper examines the nexus between shadow economy and income inequality in the West African region. The study applies second-generation panel estimation techniques to analyze the effect and the direction of causation between the variables. The results reveal that the shadow economy reduces income inequality in the region in both short-run and long-run estimations. A similar result is documented when alternative estimation techniques are employed. In addition, the panel causality results show a bidirectional relationship between shadow economy and income inequality in the West African economy. The implications of the study are discussed.
