Measuring Seaports' Productivity: A Malmquist Productivity Index Decomposition Approach

This paper uses three different Malmquist productivity index (MPI) decompositions to measure Greek seaports' productivity for the period 2006–10. Bootstrap techniques are applied in order for confidence intervals of MPIs and their components to be constructed, and to verify if the indicated changes are statistically significant. Finally, a second-stage nonparametric analysis is applied identifying the effect of seaports' size on their productivity levels. The results reveal that the number of terminals is a crucial determinant of seaports' productivity levels. Additionally, it appears that the high length of Greek seaports has a negative influence on their productivity levels over the years.
