Model Specification and Data
This chapter focuses upon the definition of the output and input variables that are required for developing a precise model specification, for the task of data collection and for estimating the efficiency measures for the sample from the port sector. Specifying erroneous or ill-defined variables for collection and analysis will inevitably lead to the wrong conclusions emerging, however elaborate the models employed may be. Sections 4.2-4.4 apply the performance measurement theory suggested by Norman and Stoker (1991) as guidance and utilise the existing literature as a basis for variable justification. DEA model orientation and the specification of the alternative functions for the testing of the parametric models are then discussed in Section 4.5. The detailed procedure to be employed for data collection is reported in Section 4.6 and, finally, Section 4.7 summarises this chapter.
