A dynamic model for an optimal specific import tariff
The existing literature on optimal specific import tariff only compares the pre- and the post-tariff market equilibriums to account for the efficiency losses. However, when the government imposes a tariff, it affects the import quantity, hence pushing the market out of equilibrium. The supply and the demand of the commodity on which a tariff is imposed then adjust over time to bring the new equilibrium. This article develops a dynamic model and derives an optimal specific import tariff path minimizing the efficiency losses during the adjustment process as well as the post-tariff equilibrium subject to a tariff revenue constraint.
