Malmquist productivity index

Measuring seaports' productivity: A Malmquist productivity index decomposition approach. MPRA Paper. 40174, University Library of Munich, Germany.

This paper uses three different Malmquist Productivity Index (MPI) decompositions to measure Greek seaports’ productivity for the time period 2006-2010. In addition bootstrap techniques are applied in order for confidence intervals of the MPIs and their components to be constructed and therefore to verify if the indicated changes are significant in a statistical sense. Finally, a second stage nonparametric analysis has been applied identifying the effect of seaports’ size on their productivity levels.
