Selv om disse forskelle i nogen udstrækning kan skyldes forskelle i udenrigshandelsstrukturen, er der også noget der taler for, at udenlandske leverandører som en reaktion på de store valutakursændringer har mindsket deres fortjenstmargen på markeder i lande, hvis valuta er blevet nedskrevet, og forhøjet deres salgspriser (i deres egen valuta) i De forenede Stater i 1981 og 1982.
Although these differences may be due, to some extent, to divergences with respect to the structure of foreign trade, it would also seem likely that foreign suppliers have reacted to the large exchange rate changes by reducing their profit margins in markets where the currency has depreciated and by raising their sales prices (in their own currency) in the United States in 1981 and 1982.
