abstract

The aim of this study is to evaluate the operating efficiency and productivity changes of the Greek airports, during the first years of the severe economic crisis in Greece (2010e2014), by using two methods: Data Envelopment Analysis (DEA) and Malmquist Productivity index (MPI). Findings have shown that, despite the dramatic effects of the economic crisis on the socio-economic life of the country, overall airport efficiency and productivity improved, mainly due to exogenous factors such as international tourism growth. The MPI reveals that over the period of the study, airports have experienced an annual average increase in total factor productivity (TFP) of 0.9% (an increase of 3.6% over the examined period). On examining the components of this productivity change, it becomes evident that this is due to the combination of both positive (a slight progress) annual average technology change (0.5%) and technical efficiency change (0.4%). The results also indicate that 65.8% of airports have an increase in average TFP during the period 2010e2014, ranging between 0.4% and 20%. However, as Greek airports operate at poor levels of efficiency, there is still considerable space for improvements in most of the airports.

5. Concluding remarks

The aim of this study is to evaluate the operating efficiency and productivity changes of the Greek airports, during the first five years of the severe economic crisis in Greece. Data analysis showed that during the study period 2010e2014, tourist arrivals in Greece followed an upward trend. During this period Greek airports have strongly supported tourism, making a vital contribution to the Greek economy in the first years of the economic crisis. We applied DEA analysis using panel data for the period 2010e2014 for the 38 Greek airports, which are owned, controlled and managed centrally by the HCAA. It has become evident that overall Greek airports have considerable scope for improvement, as the average efficiency ratio is stable close to 54% in the study period, peaking at 55.6% in 2014. Only seven out of the thirty-eight airports included in the study exhibit the highest level of efficiency and maintain this throughout the whole period (2010e2014). Those are: Thessaloniki, Heraklio, Kos, Chios, Paros, Kastelorizo and Kasos. Year to year efficiency analysis showed no regular trend or variation in the efficiency of the Greek airports during the examined period. Even though there are some differences between the efficiency ratios, the results show that airports are characterized either by a low or a high ratio of efficiency. The analysis showed that noteworthy changes were mainly triggered by exogenous factors such as significant increase in traffic or in infrastructure. However, in cases of very low efficiency not even substantial traffic increase was enough to considerably improve it
