Impact of RTA and PTA on Bangladesh’s Export: Application of a Gravity Model

As part of its growth strategy, Bangladesh instituted a trade liberalization process in the early 1990s which gained momentum in later years. Trade grew from 24.4 to 45% of GDP between 1980–81 and 2007–08, an indicator of increased liberalization as well as the growing importance of the external sector in Bangladesh. Apart from its unilateral liberalization, Bangladesh participates in three different regional trade agreements (RTAs): the South Asian Free Trade Agreement (SAFTA), the Asia Pacific Trade Agreement (APTA) and the Bay of Bengal Initiative for Multisectoral Technical and Economic Cooperation Free Trade Area (BIMSTEC FTA). In addition, Bangladesh signed preferential trade agreements (PTAs) with the member countries of the Developing 8 (D8). Because of the growing importance of RTAs, this study investigates their contribution to the export flows from Bangladesh using the gravity model that has become the primary tool for estimating the trade effects of regional integration. Regression results of bilateral exports for 40 countries from 1992–2009 indicate two crucial aspects. Firstly, all the RTAs consistently maintained statistically significant negative signs, except the BIMSTEC FTA and SAFTA, which showed insignificantly positive and insignificantly negative effects respectively. Secondly, the intensity of negative effects and the level of significance have shown a declining trend as the status of those blocs has changed from political or economic cooperation agreements to preferential agreements and from preferential agreements to free trade agreements. Thus, the intensity of tariff liberalization and the degree of sectoral coverage seem to be the important determinants of the RTAs’ performance. Therefore, experts expect that full-fledged implementation of FTA provisions and the elimination of all tariff and non-tariff barriers might result in a higher degree of integration.
