Preference Erosion, Government Revenues and Non‐tariff Trade Barriers

Developing countries benefiting from developed country unilateral trade preferences fear that Doha Round tariff cuts will erode the value of those preferences. That these programmes confer significant benefits, however, is not clear. Studies indicate that the impact of preference erosion would be minimal for most developing countries. But for a small subset of middle‐income and least‐developed countries, concern may be warranted. WTO members, should address affected countries’ concerns, perhaps by tailoring WTO tariff negotiations to lessen adjustment pressures and providing development assistance. Developing countries also are anxious that lower tariffs will reduce government revenues. Dependence on tariff revenue is diminishing and trade liberalisation need not result in lower total tax revenues or even lower customs revenues. Much depends on a country's current tariff and trade regime, its tax structure and its overall economic structure. At some point, a country does need to broaden its tax base and look to other revenue sources to offset declining tariff revenues. Tax reform, therefore, complements trade reform. A third area of developing country concern is non‐tariff barriers (NTBs), which may limit market access even after tariffs are reduced. Despite prior WTO work in this area, NTBs remain a thorny issue for all WTO members.
