The adjustment of global external imbalances

"Recent papers have found evidence of a decline in exchange rate pass-through to import prices in the United States and in a number of other industrial countries as well. This paper examines the implications of a decline in pass-through for the prospective adjustment of global external imbalances. We find that a decline in pass-through to trade prices may mute the responsiveness of the nominal trade balance to shifts in the exchange rate, but that a decline in pass-through does not shut down nominal adjustment completely. We also find that the channels of adjustment vary with pass-through. When pass-through is high, nominal adjustment is driven by moves in trade quantities. When pass-through is low, nominal adjustment mainly reflects shifts in the terms of trade (i.e., export prices relative to import prices). Our work employs a forward-looking, optimizing model in which firms set their prices with an eye toward maintaining their competitiveness against other producers; this feature of the model generates a variable desired markup and, hence, exchange rate pass-through that is less than complete"--Federal Reserve Board web site.
