This question asks you to compute valuation effects for the United States in 2015 using the same methods mentioned in the chapter. Use the bea.gov website to collect the data needed for this question: look under the “International” heading.
Visit the BEA’s balance of payments data page and obtain the U.S. balance of payments for 2015 in billions of dollars. Be sure to get the correct year, and annual data, not quarterly.
Visit the BEA's net international investment position data page and obtain the U.S. net international investment position for end 2014 to end 2015.
Answers may vary based on data revisions. The data below were obtained in March 2017.
a. What was the U.S. current account for 2015?

b. What was the U.S. financial account for 2015?

c. What was the U.S. change in external wealth for 2015?

d. What was the U.S. total valuation effect for 2015?

e. Does the answer to part (d) equal the answer to part (e) minus the answer to part (c)? Why?

f. What do the BEA data indicate was the U.S. valuation effect due to exchange rate changes for 2015?

g. What were end-2014 U.S. external liabilities? If 5% of these liabilities were in foreign currency and were subject to a 10% exchange rate appreciation, what decrease in U.S. external wealth resulted?

h. What were end-2014 U.S. external assets? If 65% of these assets were subject to a 10% exchange rate appreciation, what increase in U.S. external wealth resulted?

i. Using the answers to parts (g) and (h), what was the 2015 U.S. valuation effect due to exchange rate changes according to your rough calculation? Is it close to the BEA figure in part (f)?
