This study presents an evaluation of the relative efficiency of sixteen container ports in Sub-Sahara Africa using three DEA models namely CCR, BCC and Super-Efficiency over the year 2012. The CCR and BCC models are used to estimate the technical and scale efficiency while the super-efficiency technique provides a ranking of efficient ports. The efficiency results indicate that on average the i...
