price of beef in the U.S. is $2.80 per pound, and in Britain it is £3.70 per pound.
a. According to PPP theory, what should the $/£ spot exchange rate be?
b. Suppose the price of beef is expected to rise to $3.10 in the United States, and to £4.65 in
Britain. What should the one-year forward dollar/pound exchange rate be?
c. Given your answers to parts a and b, and given that the current interest rate in the United
States is 10 percent, what would you expect the current interest rate to be in Britain?
or 0.67$/£.
c. Since the dollar is appreciating relative to the pound, and given the relationship of

for the Brazilian real?
b. Is a decline in value of the real against the U.S. dollar good for Embraer, bad for
Embraer, or a mixed bag? Explain your answer.
c. What kind of foreign exchange risks is Embraer exposed to? Can Embraer reduce these
risks? How?
