Abstract

AbstractThis paper studies the existence of non-linear dynamics and chaos in the Spanish maritime transport services for the period 1992–2007. Using monthly time series data and the Box-Jenkins approach for time series analysis as a preparatory step in order to obtain linear model and applying the BDS test to residuals obtained, we find that a number of sea traffic series – total cargo, solid bulk, liquid bulk, containered and non containered general cargo – do not show significant nonlinear dependence and hence chaos cannot be inferred.
