Is There Any Efficiency Difference between Input and Output Oriented DEA Models: An Approach to Major Ports in India
Dr. T. Rajasekar, Dr. Malabika Deo

Abstract
In this paper, an attempt has been made to measure the efficiency difference between input and output oriented Data Envelopment Analysis (DEA) models for major ports in India over the period of 1993 - 2013. It was assumed that there is no difference between the efficiency of ports based on its orientation i.e. either input oriented or output oriented. Based on the empirical results, the operational efficiency of the ports like JNPT, Kandla, Mormugao and Ennore was observed as efficient ports in both the orientation. Thus can be conclude that there is no difference in efficiency identification of Decision Making Units (DMUs). The results also indicates that steps to be taken to strengthen the operation of inefficient ports, more specifically to upgrade the infrastructure of the ports, some ports need technological improvement. However the caution should be taken while interpreting the efficient ports like JNPT, Kandla, Mormugao and Tuticorin, they may be better in comparison to the other ports in India but may not be the same, when compared with world ports. This should strive for still better operational to be at par with efficient ports in rest parts of the world.
