Did one-sided tariff cuts raise incomes while amplifying trade shocks?
Core argument: China's tariff reductions after its WTO accession exceeded the norm of reciprocity, under which exchanged tariff cuts leave relative world prices between countries unchanged.
When countries exchange tariff cuts that abide by reciprocity, relative world prices (the terms of trade between them) do not change. We find the tariff reductions China implemented after its WTO accession exceeded the norm of reciprocity. This deviation from reciprocity increased aggregate real incomes in the United States and in the rest of the world through improvements in their terms of trade, but it also amplified the magnitude of the China Shock. Figure 2 presents the percentage change in employment in the tradable sector and in the non-tradable sector in the rest of the world due to the movement in the terms of trade resulting from the actual changes in tariff between China and the rest of the world from 1990-2007. We find that China exceeding reciprocity resulted in employment shifting from the tradable sector to the nontradable sector in the rest of the world.
