Transforming Accessions Data into Knowledge

Accessions to the World Trade Organization (WTO) generate large amounts of data accumulated during accession negotiations and subsequent domestic reforms. Owing to differences in the structure of acceding economies, accession commitments vary across recently acceded, or Article XII, members, in the number of tariff lines bound, the level of bindings and the various accession-specific commitments and obligations. The depth of commitments and extent of post-accession implementation influence the effectiveness of benefits derived by new members from WTO accession. In spite of the generally positive economic performance exhibited by all Article XII members, disparities exist in their country-specific economic performance in terms of trade, foreign direct investment (FDI) and gross domestic product (GDP) growth. This chapter analyses the impact and depth of accession commitments to assess the economic effects of WTO accession. It explores how the data from accessions acquis can assist policy-makers in implementing structural reforms and integrating their countries into regional and global value chains. An Accession Commitment Index is proposed as a basis for a statistical exploration of the impact of WTO accession on a series of variables related to economic growth. Using an extension of the difference-in-difference methodological approach, the chapter finds that WTO accession generally has a positive and significant impact on the acceding economy’s trade and economic performance. The results also show that the impact of WTO membership on the trade/GDP ratio in developing countries is significantly higher than in previous studies.
