Abstract

This paper analyses the extent of technical change and technical efficiency in Portuguese seaport costs between 1990 and 2000, using a stochastic cost frontier method. A translog frontier and the maximum likelihood estimation technique are employed to estimate the empirical model. The results show that the average score of inefficiency is 39.6%, denoting a high degree of waste in the use of resources, despite the fact that technical change contributed to a reduction of costs. Maritime Economics & Logistics (2005) 7, 297–315. doi:10.1057/palgrave.mel.9100140
