Substantial attention has been devoted to the disasterous effects of implementing a Donald Trump agenda of imposing 45% tariffs on imports of goods from China. To gain some perspective, consider the implications for prices of goods imported from China if such a tariff were imposed (and a large country assumption used, so that only half of the tariff increase manifested in increased prices).
Figure 1: Price of Chinese commodity imports, 2003M12=100, with 2016M03 values at 2016M02 values (bold blue), and a 22.5% higher price level as of 2017M02 assuming the half of incidence falls on the US (red). Light green shaded area denotes projection period. Vertical axis is logarithmic. Source: BLS, and author’s calculations.
Obviously, drop the large country assumption, and the resulting price increase can be up to 45%.
