Two countries, Great Britain and the U.S., produce just one good: beef. Suppose that the 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 U.S., and to 4.65 in Britain. What should the one-year forward $/ 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? there are two answers for this question on Chegg and I don't know which calculation is correct.
