CHAPTER 8 MANAGEMENT OF TRANSACTION EXPOSURE SUGGESTED ANSWERS AND SOLUTIONS TO END—OF—CHAPTER QUESTIONS ANDPROBLEMSQUESTIONS1。
How would you define transaction exposure? How is it different from economic exposure? Answer：Transaction exposure is the sensitivity of realized domestic currency values of the firm’s contractual cash flows denominated in foreign currencies to unexpected changes in exchange rates。
Unlike economic exposure, transaction exposure is well-defined and short-term。
2。
Discuss and compare hedging transaction exposure using the forward contract vs。
money market instruments。
When do the alternative hedging approaches produce the same result？Answer: Hedging transaction exposure by a forward contract is achieved by selling or buying foreign currency receivables or payables forward。
On the other hand，money market hedge is achieved by borrowing or lending the present value of foreign currency receivables or payables, thereby creating offsetting foreign currency positions. If the interest rate parity is holding， the two hedging methods are equivalent。
