Zusammenfassung
This paper sheds light on the export structure of the four European countries Portugal, Ireland, Greece and Spain, the so called PIGS countries. These countries were all hit by the economic downturn in the course of the financial crisis and have been struggling with the national debt crisis and recession. One way to identify sectoral international competitiveness is provided by the revealed comparative advantage index developed by Balassa (RCA 1). This indicator was evolved through several studies, for example by the German council of experts (RCA 2). Both indicators suggest that the dominant advantages of Portugal and Greece can be found within agriculture and natural resources. The dominant export sectors are located there, too. Ireland stands out from the PIGS, as high-tech and medical/chemical products occur in the top sectors. Spain’s top export sectors do not have the competitiveness that one might expect. The Balassa-Index is than transformed to a standardized and symmetric index RSCA and is plotted against the trade balance index (TBI). Thus, information on country´s trade structure can be depicted. Ireland´s industry is to a certain extent dependent on the world market. Export growth will not have a major impact in Greece and Portugal. Spain does have competitive sectors and a degree of specialization, but in fact the most important export sectors are less competitive. Finally, the level of specialization (β–specialization) and the specialization-process (σ–specialization) are identified by a short OLS-estimation. The β-specialization does not indicate high degrees of specialization in those countries. According to the σ-specialization, there do not seem to be significant specialization or de-specialization trends since 1995.
