Analysis of the Role of Tariff Concessions in East Asia

While there are many studies focusing on the impacts of various trade policy agreements across the world in the recent years, there is not much focus in the literature on the extent to which these agreements are implemented later, in terms of the aspects agreed upon therein. In this paper, we firstly identify the past achievements of the Economic Partnership Agreements (EPAs) in East Asian regions in terms of tariff removals and suggest future rooms for further economic benefits from trade liberalization in the region. Secondly, we provide the tariff concession dataset in the GTAP Data Base, which distinguishes the tariff removals agreed in these EPAs in East Asia but not implemented yet, from the existing overall tariffs in the benchmark year. As the standard GTAP Data Base only incorporates enforced tariff reductions through the base year applied tariffs, to analyse future trade integration, it might be worth it to integer commitments that are not yet implemented. We do that at the HS6 levels for East Asian EPAs that allows us to compare the economic impacts of partial versus complete implementation of the trade liberalization agreed in East Asian EPAs. Our results suggest that taking those commitments into account economically matters and that such satellite dataset might be taken as actual baseline for future policy simulations.
