The data showing the graphical relationships between U.S. dollar exchange rate changes,
aggregate import prices, and import prices for Japan, the NIEs, the EU, and Japan are shown in
Appendix Figures A.1 to A.6. The exchange rate is denoted as dollars per foreign currency unit
so that an increase in the exchange rate represents a depreciation of the dollar. One would expect
a positive correlation between the exchange rate and import price changes. All data are in natural
log first differences, reported on a quarterly basis. The figures show how import prices have
changed with the exchange rate from 1999 to 2008
