The impacts of non-tariff barriers on the export price of Vietnamese catfish
AuthorKhuu, Thi Phuong Dong
The aims of this study to identify the impacts of non-tariff barriers (NTBs) on Vietnamese catfish export price in the international market. The time-series monthly data from 1999 to 2011 was used in our paper. Base on the demand and supply equilibrium theory, we constructed the function of Vietnamese catfish export price. The unit toot test results showed that our data was stationary at differenced level. Therefore, the econometric models, such as first-differenced model, Error correction model (ECM) and the lagged transformation model were employed to estimate the effects of NTBs on the Vietnamese catfish export price. The antidumping, the labeling law and the technical barriers were the most popular of NTBs used for Vietnamese catfish products. The NTBs were considered in our model under the dummy form with. Beside the NTBs, some other macroeconomic variables were added to the model as the demand and supply shifters, such as exchange rate, income per capita, the price of substitute goods (poultry, salmon, the US catfish), the price of input cost (fishmeal, fuel). The estimated of the econometric models showed that, in the short run, the US catfish price was the alternative goods of Vietnamese catfish. We found that the NTBs were not significant in the dynamics of Vietnamese catfish export price in the short run. However, in the long run, the antidumping had the negative effects on the Vietnamese catfish export price. The estimated ECMs model demonstrated that the Vietnamese catfish export price decreased about 9% after antidumping be effective. However, the labeling law and the imposed of HACCP standards did not have more significant in the change of Vietnamese catfish. The application of GLOBAL GAP in catfish producing process did not illustrated negative effects as our expected results. This could be argued that the application of GLOBAL GAP had the positive effects on the consumer’s belief in the long run.
