Trends in Agricultural Production Efficiency and their Implications for Food Security in Sub‐Saharan African Countries.

The main objective of this paper is to estimate the agricultural sector production efficiency using data envelopment analysis based on a cross‐section of 49 African countries over the 1995–2012 period in order to analyze the determinants of annual efficiency scores to assess the impact of agricultural efficiency on food security. We find that agriculture aid, agricultural sector infrastructure, sanitation, and good governance serve the main drivers of agriculture efficiency and its growth. Our findings also suggest that a large portion of Africa's agricultural sector growth can be attributed to technical progress as opposed to efficiency changes. [ABSTRACT FROM AUTHOR]
