The objective of this thesis outlines an attempt to evaluate the productive & financial efficiency, of 30 Greek and International shipping companies, listed in the New York Stock Exchange (NASDAQ) with Data Envelopment Analysis (DEA) for the period 2014-2016. The sample that has been used in our analysis, contains the aggregate of the Greek shipping companies that are listed in NASDAQ, as well as the most international ones, which offer international seaborne transportation services in multiple industry sectors such as dry bulk, liquid bulk and container. For the assessment of the efficiency of the shipping companies, numerous inputs and outputs has been used, whereas the data has been derived from Clarkson’s database, the companies’ websites and their annual reports for the aforementioned period of time. In the analysis there has been used multiple DEA model of CCR & BCC, oriented either on inputs or outputs. In addition there has been checked if there is a correlation between the size of the shipping companies and the model results and how the results is being affected by this parameter. This hypothesis has been checked by dividing the sample into two smaller groups, of small-medium and large shipping companies. The evaluation of the results of our analysis came to the conclusion that large sized shipping companies are more efficient, with the year 2014 being the most efficient year for all the shipping companies of the sample. Finally, an important observation that has emerged and deserves to be highlighted is that, large-scale shipping companies with high profitability does not necessarily suggest high efficiency.
