Abstract EN:

The purpose of this work is to study the effectiveness of non-reciprocal preferential agreements. To do this we conducted a comparative analysis between the beneficiary countries of the Lomé agreements and a sample of developing countries in Latin America, Asia and the Middle East. The empirical approach uses a gravity model applied to the panel data over a period of 29 years. The sample used is composed by the group of developing countries already mentioned, including members of the Lomé Convention, and a group of industrialized countries, a total of 122 countries The 2 approaches, cross sectional and longitudinal analysis, among other things, confirm that the membership of Lomé has not been a positive factor for bilateral trade, the influence of historical factors (the common language and the colonial past) remain important, other things being equal. Belonging to the developing countries of Asia and Latin America is a positive factor in bilateral trade, after controlling other variables
