Shipping the good fish out? An empircal study on the EU seafood imports under the EU's Generalized System of Preferences

The impact of the EU (European Union) Generalized System of Preference (GSP) on the relative EU's demand for seafood quality was evaluated in the study. We first explored the theoretical Alchian-Allen result of change in ad valorem tariffs in an n-good world, and then tested this result in the empirical study The theoretical analysis suggests that whether a reduced ad valorem tariff in an n-good case raises the relative demand for high-value goods depends not only on the substitutability between high value and low-value goods but also on the substitutability between these similar goods with their weak substitutes. In the empirical sections, we first estimated the elasticities of the substitutions and then used these elasticities to evaluate the quality composition of the EU's seafood imports from the beneficiary countries. The empirical results, in general confirm the occurrence of 'shipping the good fish out' due to the reduced tariff rates under the EU's GSP arrangements.
