A key conclusion is that shocks would have to be very large in order to materially reduce the US external deficit. In part, this is because second-round effects, including domestic policy responses, tend to offset the shocks’ initial impact. In addition, it is clear that each of the channels for narrowing the deficit involves risks to growth in the rest of the world, particularly in Japan where the authorities have limited room to use monetary or fiscal policy to offset any contractionary pressures. The exchange rate simulations highlight the fact that more exchange rate flexibility in Asia would spread the burden of adjustment more evenly across US trading partners. Attention is also ...
