Governance quality, remittances and their implications for food and nutrition security in Sub-Saharan Africa
基于15个撒哈拉以南非洲国家1996-2015年的面板数据，研究发现汇款与治理质量的交互作用显著提升了粮食生产价值和膳食能量供给充足率，其中控制腐败的效果最大。
Despite impressive progress in the fight against malnutrition and hunger in recent years, food and nutrition insecurity remains a major concern in Sub-Saharan Africa (SSA) countries. In this study, we employ a panel data covering 15 SSA countries from 1996 to 2015 to investigate the growth effects of remittances and quality of governance on food and nutrition security, proxied by the average value of food production and the average dietary energy supply adequacy, respectively. We use a dynamic empirical model based on system GMM to control for unobserved heterogeneity and potential endogeneity of the explanatory variables. The empirical results emanating from our analysis show that the interaction of remittances and the composite index of governance quality exerts positive and significant effects on the average value of food production, and also contributes to the improvement of average dietary energy supply adequacy in SSA. In addition, the control of corruption, government effectiveness, political stability and rule of law scores increase both measures of food and nutrition security. Albeit, the contribution of control over corruption score is relatively the largest as compared to other indicators of governance.
