The article compares the productivity of Norwegian container ports with similar ports in the Nordic countries and the UK from 2009 to 2014. They used a method called Malmquist Productivity Index to analyze changes in productivity. The main findings are: 1) Norwegian ports are more efficient than their international counterparts; 2) Norwegian ports show productivity growth over time, but they are not statistically better than others; 3) Overall, all ports improved productivity by about 0.6% per year, mainly due to technological advancements rather than efficiency improvements.
