The results indicate that the reduction in import tariff of Malaysian RBD Olein by 10 percent will cause the price to decrease by around 7.3 percent. The decline in Malaysian RBD olein price will increase its demand in Pakistan by around 4.4 percent. While import demand of Indonesian RBD Olein in Pakistan estimated to increase by only 0.35 percent, this is because the price of Indonesian RBD Olein rises by 0.17percent.
