Conclusion

Following earlier reservations concerning the use of Glejser et al.’s index, this paper has attempted to show that Glejser et al.’s basic ideas concerning the measurement of the extent of specialization in imports and exports did not depend on the use of a specific index. Any measure of the inequality of the ratios (M i/Mgi) defined earlier (and similarly for exports) could, in fact, be used. The empirical section of this paper, which looked at the commodity composition of the exports and imports of Denmark, Ireland and the United Kingdom, before and after they joined the EEC, confirmed that there was a positive correlation between the various indices proposed.
