This paper provides a comparative study of how U.S. imports and exports prices react to exchange rate changes. It finds, through time series analyses, that while both U.S. and foreign exporters price to market, foreign exporters in general absorb a large portion of exchange rate changes by themselves while U.S.exporters pass through most of the exchange rate change to foreign currency prices. Pricing behavior of U.S. imports and, to a lesser extent, of U.S. exports varies across industries and such variation relates to industry characteristics such as market shares, product differentiation, and capital-to-labor ratio.
