The combined effect of institutional quality and capital flows on food and nutrition security and undernourishment in Sub-Saharan Africa

Issues related to malnutrition, broadly defined, have received a growing attention in recent years, not only in connection with the Sustainable Development Goals but also recently with the unprecedented Covid-19 pandemic. At the same time, there exists a complex interaction between institutions, capital flows, and food and nutrition security that has received less attention in the relevant literature. In this paper we estimate a series of dynamic panel data models to examine the impact of institutional quality and capital flows on food security, nutrition security and undernourishment by using panel data for 25 SSA countries over the period 1996 to 2018. One of the key contributions of the paper is the use of both aggregate and disaggregated capital flows to examine the impact on both food and nutrition security, a dimension that has been surprisingly neglected in most of the relevant literature. We combine this with the interaction of various types of capital flows with an institutional quality index we constructed from various governance indicators to examine the impact of institutions on the overall nexus. Finally, we examine the impact not only on food and nutrition security but also on undernourishment. Our findings clearly demonstrate the importance of a heterogeneity approach and reflect on earlier work regarding the role of institutional quality in the overall nexus between external capital flows and various measures of food and nutrition security which leads, and as expected, to an interesting variation in the results obtained, depending on the type of capital flows and the interaction with the governance indicators.
