ABSTRACT

The study draws inference on the impact of agricultural trade openness, total factor productivity (TFP) growth, and domestic agriculture support on food security in Africa. To retain estimates efficiency and consistency in the presence of complex error terms, we employed the Panel-Corrected-Standard-Error (PCSE) estimator on panel data spanning 2005–2016 for 13 African countries. Results suggest that agricultural trade liberalisation and TFP have significant and favourable effects. Moreover, we find that reducing agricultural support beyond distortion-free levels enhances food security. Further to trade openness, we call for export growth-oriented domestic support anchored on agricultural human-capital development, innovation, and research and development.

摘要

该研究推断农业贸易开放、全要素生产率 (TFP) 增长和国内农业支持对非洲粮食安全的影响。为了在存在复杂误差项的情况下保持估计的效率和一致性，我们对 13 个非洲国家 2005-2016 年的面板数据使用了面板校正标准误差 (PCSE) 估计器。结果表明，农业贸易自由化和全要素生产率具有显着且有利的影响。此外，我们发现，将农业支持减少到超出无扭曲水平的水平可以增强粮食安全。在贸易开放的基础上，我们呼吁以出口增长为导向的国内支持以农业人力资本开发、创新和研发为基础。
