Two countries, Great Britain and the United States, produce just one good: beef. Suppose the price of beef in the United States is $$\$ 2.80$$ per pound and in Britain it is $? 3.70$ per pound.
a. According to PPP theory, what should the dollar/pound 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?
