A very important issue regarding the evaluation of performance of shipping
companies is the measurement of a company’s operational efficiency. The majority of
studies and relevant projects concerning the evaluation of efficiency have mainly
focused in traditional statistical techniques, such as regression analysis and
performance indicators, accordingly. In this project, we use the super efficiency
model of Data Envelopment Analysis, a relatively new non- parametric method, in
our attempt to measure the operational efficiency of the major listed shipping
companies in the wet market. Specifically, we have used financial data from the
annual reports of 23 shipping companies in the LNG/LPG & the tanker sector, for the
period 2010-2013. We have also examined the relationship between economies of
scale and efficiency in the shipping market. Finally, we have used the “efficiency
profitability” matrix (another form of the “Boston Consulting Group” matrix) in order
to determine if there is any correlation between high financial profits and improved
efficiency for a shipping company. The results suggest that the majority of shipping
companies have been performing efficiently during the last 4 years and that, indeed,
achieving economies of scale can enhance efficiency for a shipping company. Finally,
our analysis for the wet shipping market suggests that being profitable enough does
not necessarily impose that a company performs efficiently in the market and as such,
managers must also emphasize in achieving profitability with the lowest mix of
inputs, in order to ensure long term sustainability and growth for their companies.
