| Abstract: | This paper provides evidence on intra-industry trade (IIT) in the Portuguese case from 1994 onwards by disentangling vertical from horizontal IIT with two different indexes - the Grubel-Lloyd and the so-called CEPII index - and analyses the determinants of both IIT types. Distinct explanatory factors are identified for each IIT type and the comparative advantage explanation in the vertical case is confirmed. The regression results are robust to different estimation methods and to alternative IIT indexes. Nonetheless, sensitivity of the IIT levels to the arbitrary criterion of the CEPII measurement points out to the Grubel-Lloyd index as a preferable method. |
