Effects of Tariffication: Tariffs and Quotas under Monopolistic Competition

  • Jan Jørgensen
  • Philipp Schröder


Recent rounds of GATT and later WTO have advocated widespread tariffication, meaning that existing non-tariff barriers be converted into import equivalent tariffs. From an economic point of view, the effects of such tariffication are not entirely clear. The paper presents a trade model with monopolistic competition to examine the welfare effects of tariffication. The ranking of pre- and post-tariffication welfare crucially depends on the nature of the initial trade barrier and the tariff tool applied. Tariffication using a specific (ad valorem) tariff results in the same (reduced) welfare level compared to an initial sold quota, whereas welfare is increased (the same) compared to an initial shared quota.
