摘要

The global urgency to eradicate widespread hunger has become increasingly critical and challenging in the quest to meet sustainable development goals (SDG-2), thereby compelling scholars and policymakers to identify potential factors influencing food security. The preponderance of extant scholarship has predominantly focused on other determinants of food security, with less evidence on the critical role of income inequality in food security. This research seeks to bridge this gap by investigating the linkage between income inequality and food security in ECOWAS countries, which remains scarce in the literature. The empirical investigation was executed using a battery of econometric strategies, such as the panel autoregressive distributed lag model (PARDL), augmented mean group (AMG), fully modified ordinary least squares (FMOLS), dynamic ordinary least squares (DOLS), and Dumitrescu and Hurlin causality test techniques. The empirical outcome reveals that deterioration in income distribution exacerbates food insecurity among households in the ECOWAS member countries. This finding indicates that rising income inequality poses greater challenges to sustainable food security in the countries analyzed. Furthermore, the causality test technique detects bidirectional causality between income inequality and food security. This study offers significant implications for curtailing food insecurity in this subregion.
