CHAPTER 7 FUTURES AND OPTIONS ON FOREIGN EXCHANGESUGGESTED ANSWERS AND SOLUTIONS TO END-OF-CHAPTERQUESTIONS AND PROBLEMSQUESTIONS1. Explain the basic differences between the operation of a currency forward market and a futures market.Answer: The forward market is an OTC market where the forward contract for purchase or sale of foreign currency is tailor-made between the client and its international bank. No money changes hands until the maturity date of the contract when delivery and receipt are typically made. A futures contract is an exchange-traded instrument with standardized features specifying contract size and delivery date. Futures contracts are marked-to-market daily to reflect changes in the settlement price. Delivery is seldom made in a futures market. Rather a reversing trade is made to close out a long or short position.2. In order for a derivatives market to function most efficiently, two types of economic agents are needed: hedgers and speculators. Explain.Answer: Two types of market participants are necessary for the efficient operation of a derivatives market: speculators and hedgers. A speculator attempts to profit from a change in the futures price. To do this, the speculator will take a long or short position in a futures contract depending upon his expectations of future price movement. A hedger, on-the-other-hand, desires to avoid price variation by locking in a purchase price of the underlying asset through a long position in a futures contract or a sales price through a short position. In effect, the hedger passes off the risk of price variation to the speculator who is better able, or at least more willing, to bear this risk.3. Why are most futures positions closed out through a reversing trade rather than held to delivery?Answer: In forward markets, approximately 90 percent of all contracts that are initially established result in the short making delivery to the long of the asset underlying the contract. This is natural because the terms of forward contracts are tailor-made between the long and short. By contrast, only about one percent of currency futures contracts result in delivery. While futures contracts are useful for speculation and hedging, their standardized delivery dates make them unlikely to correspond to the actual future dates when foreign exchange transactions will occur. Thus, they are generally closed out in a reversing trade. In fact, the commission thatbuyers and sellers pay to transact in the futures market is a single amount that covers the round-trip transactions of initiating and closing out the position.4. How can the FX futures market be used for price discovery?Answer: To the extent that FX forward prices are an unbiased predictor of future spot exchange rates, the market anticipates whether one currency will appreciate or depreciate versus another. Because FX futures contracts trade in an expiration cycle, different contracts expire at different periodic dates into the future. The pattern of the prices of these cont racts provides information as to the market’s current belief about the relative future value of one currency versus another at the scheduled expiration dates of the contracts. One will generally see a steadily appreciating or depreciating pattern; however, it may be mixed at times. Thus, the futures market is useful for price discovery, i.e., obtaining the market’s forecast of the spot exchange rate at different future dates.5. What is the major difference in the obligation of one with a long position in a futures (or forward) contract in comparison to an options contract?Answer: A futures (or forward) contract is a vehicle for buying or selling a stated amount of foreign exchange at a stated price per unit at a specified time in the future. If the long holds the contract to the delivery date, he pays the effective contractual futures (or forward) price, regardless of whether it is an advantageous price in comparison to the spot price at the delivery date. By contrast, an option is a contract giving the long the right to buy or sell a given quantity of an asset at a specified price at some time in the future, but not enforcing any obligation on him if the spot price is more favorable than the exercise price. Because the option owner does not have to exercise the option if it is to his disadvantage, the option has a price, or premium, whereas no price is paid at inception to enter into a futures (or forward) contract.6. What is meant by the terminology that an option is in-, at-, or out-of-the-money?Answer: A call (put) option with S t > E (E > S t) is referred to as trading in-the-money. If S t E the option is trading at-the-money. If S t< E (E < S t) the call (put) option is trading out-of-the-money.7. List the arguments (variables) of which an FX call or put option model price is a function. How does the call and put premium change with respect to a change in the arguments?Answer: Both call and put options are functions of only six variables: S t, E, r i, r$, T andσ. When all else remains the same, the price of a European FX call (put) option will increase:1. the larger (smaller) is S,2. the smaller (larger) is E,3. the smaller (larger) is r i,4. the larger (smaller) is r$,5. the larger (smaller) r$ is relative to r i, and6. the greater is σ.When r$ and r i are not too much different in size, a European FX call and put will increase in price when the option term-to-maturity increases. However, when r$ is very much larger than r i, a European FX call will increase in price, but the put premium will decrease, when the option term-to-maturity increases. The opposite is true when r i is very much greater than r$. For American FX options the analysis is less complicated. Since a longer term American option can be exercised on any date that a shorter term option can be exercised, or a some later date, it follows that the all else remaining the same, the longer term American option will sell at a price at least as large as the shorter term option.PROBLEMS1. Assume today’s settlement price on a CME EUR futures contract is $1.3140/EUR. You have a short position in one contract. Your performance bond account currently has a balance of $1,700. The next three day s’ settlement prices are $1.3126, $1.3133, and $1.3049. Calculate the changes in the performance bond account from daily marking-to-market and the balance of the performance bond account after the third day.Solution: $1,700 + [($1.3140 - $1.3126) + ($1.3126 - $1.3133)+ ($1.3133 - $1.3049)] x EUR125,000 = $2,837.50,where EUR125,000 is the contractual size of one EUR contract.2. Do problem 1 again assuming you have a long position in the futures contract.Solution: $1,700 + [($1.3126 - $1.3140) + ($1.3133 - $1.3126) + ($1.3049 - $1.3133)] x EUR125,000 = $562.50,where EUR125,000 is the contractual size of one EUR contract.With only $562.50 in your performance bond account, you would experience a margin call requesting that additional funds be added to your performance bond account to bring the balance back up to the initial performance bond level.3. Using the quotations in Exhibit 7.3, calculate the face value of the open interest in the June 2005 Swiss franc futures contract.Solution: 2,101 contracts x SF125,000 = SF262,625,000.where SF125,000 is the contractual size of one SF contract.4. Using the quotations in Exhibit 7.3, note that the June 2005 Mexican peso futures contract has a price of $0.08845. You believe the spot price in June will be $0.09500. What speculative position would you enter into to attempt to profit from your beliefs? Calculate your anticipated profits, assuming you take a position in three contracts. What is the size of your profit (loss) if the futures price is indeed an unbiased predictor of the future spot price and this price materializes?Solution: If you expect the Mexican peso to rise from $0.08845 to $0.09500, you would take a long position in futures since the futures price of $0.08845 is less than your expected spot price.Your anticipated profit from a long position in three contracts is: 3 x ($0.09500 - $0.08845) x MP500,000 = $9,825.00, where MP500,000 is the contractual size of one MP contract.If the futures price is an unbiased predictor of the expected spot price, the expected spot price is the futures price of $0.08845/MP. If this spot price materializes, you will not have any profits or losses from5. Do problem 4 again assuming you believe the June 2005 spot price will be $0.08500.Solution: If you expect the Mexican peso to depreciate from $0.08845 to $0.07500, you would take a short position in futures since the futures price of $0.08845 is greater than your expected spot price.Your anticipated profit from a short position in three contracts is: 3 x ($0.08845 - $0.07500) x MP500,000 = $20,175.00.If the futures price is an unbiased predictor of the future spot price and this price materializes, you will not profit or lose from your long futures position.6. George Johnson is considering a possible six-month $100 million LIBOR-based, floating-rate bank loan to fund a project at terms shown in the table below. Johnson fears a possible rise in the LIBOR rate by December and wants to use the December Eurodollar futures contract to hedge this risk. The contract expires December 20, 1999, has a US$ 1 million contract size, and a discount yield of7.3 percent.Johnson will ignore the cash flow implications of marking to market, initial margin requirements, and any timing mismatch between exchange-traded futures contract cash flows and the interest payments due in March.Loan TermsSeptember 20, 1999 December 20, 1999 March 20, 2000 • Borrow $100 million at • Pay interest for first three • Pay back principal September 20 LIBOR + 200 months plus interestbasis points (bps) • Roll loan over at• September 20 LIBOR = 7% December 20 LIBOR +200 bpsLoan First loan payment (9%) Second paymentinitiated and futures contract expires and principal↓↓↓•••9/20/99 12/20/99 3/20/00a. Formulate Johnson’s September 20 floating-to-fixed-rate strategy using the Eurodollar future contracts discussed in the text above. Show that this strategy would result in a fixed-rate loan, assuming an increase in the LIBOR rate to 7.8 percent by December 20, which remains at 7.8 percent through March 20. Show all calculations.Johnson is considering a 12-month loan as an alternative. This approach will result in two additional uncertain cash flows, as follows:Loan First Second Third Fourth payment initiated payment (9%) payment payment and principal ↓↓↓↓↓••••9/20/99 12/20/99 3/20/00 6/20/00 9/20/00b. Describe the strip hedge that Johnson could use and explain how it hedges the 12-month loan (specify number of contracts). No calculations are needed.CFA Guideline Answera. The basis point value (BPV) of a Eurodollar futures contract can be found by substituting the contract specifications into the following money market relationship:BPV FUT = Change in Value = (face value) x (days to maturity / 360) x (change in yield)= ($1 million) x (90 / 360) x (.0001)The number of contract, N, can be found by:N = (BPV spot) / (BPV futures)= ($2,500) / ($25)= 100ORN = (value of spot position) / (face value of each futures contract)= ($100 million) / ($1 million)= 100ORN = (value of spot position) / (value of futures position)= ($100,000,000) / ($981,750)where value of futures position = $1,000,000 x [1 – (0.073 / 4)]102 contractsTherefore on September 20, Johnson would sell 100 (or 102) December Eurodollar futures contracts at the 7.3 percent yield. The implied LIBOR rate in December is 7.3 percent as indicated by the December Eurofutures discount yield of 7.3 percent. Thus a borrowing rate of 9.3 percent (7.3 percent + 200 basis points) can be locked in if the hedge is correctly implemented.A rise in the rate to 7.8 percent represents a 50 basis point (bp) increase over the implied LIBOR rate. For a 50 basis point increase in LIBOR, the cash flow on the short futures position is:= ($25 per basis point per contract) x 50 bp x 100 contracts= $125,000.However, the cash flow on the floating rate liability is:= -0.098 x ($100,000,000 / 4)= - $2,450,000.Combining the cash flow from the hedge with the cash flow from the loan results in a net outflow of $2,325,000, which translates into an annual rate of 9.3 percent:= ($2,325,000 x 4) / $100,000,000 = 0.093This is precisely the implied borrowing rate that Johnson locked in on September 20. Regardless of the LIBOR rate on December 20, the net cash outflow will be $2,325,000, which translates into an annualized rate of 9.3 percent. Consequently, the floating rate liability has been converted to a fixed rate liability in the sense that the interest rate uncertainty associated with the March 20 payment (using the December 20 contract) has been removed as of September 20.b. In a strip hedge, Johnson would sell 100 December futures (for the March payment), 100 March futures (for the June payment), and 100 June futures (for the September payment). The objective is to hedge each interest rate payment separately using the appropriate number of contracts. The problem is the same as in Part A except here three cash flows are subject to rising rates and a strip of futures is used to hedge this interest rate risk. This problem is simplified somewhat because the cash flow mismatch between thefutures and the loan payment is ignored. Therefore, in order to hedge each cash flow, Johnson simply sells 100 contracts for each payment. The strip hedge transforms the floating rate loan into a strip of fixed rate payments. As was done in Part A, the fixed rates are found by adding 200 basis points to the implied forward LIBOR rate indicated by the discount yield of the three different Eurodollar futures contracts. The fixed payments will be equal when the LIBOR term structure is flat for the first year.• has a principal balance of $100 million on June 30, 1998,• accrues interest quarterly starting on June 30, 1998,• pays interest quarterly,• has a one-year term to maturity, and• calculates interest due based on 90-day LIBOR (the London Interbank OfferedRate).Bower wishes to hedge his remaining interest payments against changes in interest rates.Bower has correctly calculated that he needs to sell (short) 300 Eurodollar futures contracts to accomplish the hedge. He is considering the alternative hedging strategies outlined in the following table.Initial Position (6/30/98) in90-Day LIBOR Eurodollar ContractsStrategy A Strategy BContract Month (contracts) (contracts)September 1998 300 100December 1998 0 100March 1999 0 100a. Explain why strategy B is a more effective hedge than strategy A when the yield curveundergoes an instantaneous nonparallel shift.b. Discuss an interest rate scenario in which strategy A would be superior to strategy B.CFA Guideline Answera. Strategy B’s SuperiorityStrategy B is a strip hedge that is constructed by selling (shorting) 100 futures contracts maturing in each of the next three quarters. With the strip hedge in place, each quarter of the coming year is hedged against shifts in interest rates for that quarter. The reason Strategy B will be a more effective hedge than Strategy A for Jacob Bower is that Strategy B is likely to work well whether a parallel shift or a nonparallel shift occurs over the one-year term of Bower’s liability. That is, regardless of what happens to the term structure, Strategy B structures the futures hedge so that the rates reflected by the Eurodollar futures cash price match the applicable rates for the underlying liability-the 90day LIBOR-based rate on Bower’s liability. The same is not true for Strategy A. Because Jacob Bower’s liability carries a floating interest rate that resets quarterly, he needs a strategy that provides a series of three-month hedges. Strategy A will need to be restructured when the three-month September contract expires. In particular, if the yield curve twists upward (futures yields rise more for distant expirations than for near expirations), Strategy A will produce inferior hedge results.b. Scenario in Which Strategy A is SuperiorStrategy A is a stack hedge strategy that initially involves selling (shorting) 300 September contracts. Strategy A is rarely better than Strategy B as a hedging or risk-reduction strategy. Only from the perspective of favorable cash flows is Strategy A better than Strategy B. Such cash flows occur only in certain interest rate scenarios. For example Strategy A will work as well as Strategy B for Bower’s liability if interest rates (instantaneously) change in parallel fashion. Another interest rate scenario where Strategy A outperforms Strategy B is one in which the yield curve rises but with a twist so that futures yields rise more for near expirations than for distant expirations. Upon expiration of the September contract, Bower will have to roll out his hedge by selling 200 December contracts to hedge the remaining interest payments. This action will have the effect that the cash flow from Strategy A will be larger than the cash flow from Strategy B because the appreciation on the 300 short September futures contracts will be larger than the cumulative appreciation in the 300 contracts shorted in Strategy B (i.e., 100 September, 100 December, and 100 March). Consequently, the cash flow from Strategy A will more than offset the increase in the interest payment on the liability, whereas the cash flow from Strategy B will exactly offset the increase in the interest payment on the liability.8. Use the quotations in Exhibit 7.7 to calculate the intrinsic value and the time value of the 97 September Japanese yen American call and put options.Solution: Premium - Intrinsic Value = Time Value97 Sep Call 2.08 - Max[95.80 – 97.00 = - 1.20, 0] = 2.08 cents per 100 yen97 Sep Put 2.47 - Max[97.00 – 95.80 = 1.20, 0] = 1.27 cents per 100 yen9. Assume spot Swiss franc is $0.7000 and the six-month forward rate is $0.6950. What is the minimum price that a six-month American call option with a striking price of $0.6800 should sell for in a rational market? Assume the annualized six-month Eurodollar rate is 3 ½ percent.Solution:Note to Instructor: A complete solution to this problem relies on the boundary expressions presented in footnote 3 of the text of Chapter 7.C a≥Max[(70 - 68), (69.50 - 68)/(1.0175), 0]≥Max[ 2, 1.47, 0] = 2 cents10. Do problem 9 again assuming an American put option instead of a call option.Solution: P a≥Max[(68 - 70), (68 - 69.50)/(1.0175), 0]≥Max[ -2, -1.47, 0] = 0 cents11. Use the European option-pricing models developed in the chapter to value the call of problem 9 and the put of problem 10. Assume the annualized volatility of the Swiss franc is 14.2 percent. This problem can be solved using the FXOPM.xls spreadsheet.Solution:d1 = [ln(69.50/68) + .5(.142)2(.50)]/(.142)√.50 = .2675d2 = d1 - .142√.50 = .2765 - .1004 = .1671N(d1) = .6055N(d2) = .5664N(-d1) = .3945N(-d2) = .4336C e = [69.50(.6055) - 68(.5664)]e-(.035)(.50) = 3.51 centsP e = [68(.4336) - 69.50(.3945)]e-(.035)(.50) = 2.03 cents12. Use the binomial option-pricing model developed in the chapter to value the call of problem 9.The volatility of the Swiss franc is 14.2 percent.Solution: The spot rate at T will be either 77.39¢ = 70.00¢(1.1056) or 63.32¢ = 70.00¢(.9045), where u = e.142 .50 = 1.1056 and d = 1/u = .9045. At the exercise price of E = 68, the option will only be exercised at time T if the Swiss franc appreciates; its exercise value would be C uT= 9.39¢ = 77.39¢ - 68. If the Swiss franc depreciates it would not be rational to exercise the option; its value would be C dT = 0.The hedge ratio is h = (9.39 – 0)/(77.39 – 63.32) = .6674.Thus, the call premium is:C0 = Max{[69.50(.6674) – 68((70/68)(.6674 – 1) +1)]/(1.0175), 70 – 68}= Max[1.64, 2] = 2 cents per SF.MINI CASE: THE OPTIONS SPECULATORA speculator is considering the purchase of five three-month Japanese yen call options with a striking price of 96 cents per 100 yen. The premium is 1.35 cents per 100 yen. The spot price is 95.28 cents per 100 yen and the 90-day forward rate is 95.71 cents. The speculator believes the yen will appreciate to $1.00 per 100 yen over the next three months. As the speculator’s assistant, you have been asked to prepare the following:2. Determine the speculator’s profit if the yen appreciates to $1.00/100 yen.3. Determine the speculator’s profit if the yen only appreciates to the forward rate.4. Determine the future spot price at which the speculator will only break even.Suggested Solution to the Options Speculator:1. +-2. (5 x ¥6,250,000) x [(100 - 96) - 1.35]/10000 = $8,281.25.3. Since the option expires out-of-the-money, the speculator will let the option expire worthless. He will only lose the option premium.4. S T = E + C = 96 + 1.35 = 97.35 cents per 100 yen.。

Chapter 3Foreign Exchange Determination andForecasting1. Applying expansionary macroeconomic policy, which results in higher goods prices and lower realinterest rates, will not reduce the balance of payments deficit. Higher prices will make the country’s goods less competitive internationally, and lower interest rates will discourage foreign capital. Thus, the balance of payments deficit will worsen instead of improve. On the other hand, (a), (b), and (d) will help in remedying the balance of payments deficit. Accordingly, the answer is (c).2. a. One advantage of a wider band is “emotional.” France could claim that it did not devalue itscurrency. Another advantage is flexibility. If there were no long-term fundamental reasons(inflation, balance of payments deficit, etc.) for a devaluation, the temporary pressure on thefranc could ease and the franc could later revert to its previous level. The disadvantage of a wider band is exchange rate uncertainty for all firms. A “credible” small band is preferable for firmsconducting international trade,b. A wider band makes speculation less attractive, because there is no guarantee that a central bankwill defend its currency until the wide fluctuation margin is reached.3. a. The American investor has paid a 25 percent premium over the price paid by a domestic investor.Yet, he receives the same dividends as the domestic investor. Therefore, his investment bears asmaller yield than it would for a domestic investor.b. Lifting of the exchange controls would be bad news to an existing foreign investor in Paf, sinceher asset could only be repatriated at the normal pif rate (1.00), while she had bought it at thefinancial rate (1.25).c. Lifting of the exchange controls would be good news to foreign investors planning to invest inPaf in the future, because they would no longer have to pay the 25 percent premium when buying assets in Paf.4. Remember that the Eurozone is made up of those countries in the EU that have adopted the euro ascommon currency. Statements I and III are clearly correct. Statement II is clearly not correct, because there is a possibility that more countries may join the Eurozone in future. For example, the British are debating whether to join the Eurozone.5. The statement is true. Because of riskless arbitrage, interest rate parity between two currencies wouldhold if the markets for both are free and deregulated. Developed financial markets tend to be more free and deregulated. A developing country is more likely to impose various forms of capital controls and taxes that impede arbitrage. A developing country is economically not as well integrated with the world financial markets as the developed markets are. Also, some smaller currencies can only be borrowed and lent domestically, and the domestic money markets of developing countries are more likely to be subjected to political risk.Chapter 3 Foreign Exchange Determination and Forecasting 156. a. Using the first-order approximation of PPP relationship, the variation in rupee to dollar exchangerate should equal the inflation differential between rupee and dollar. So, the rupee to dollarexchange rate should increase by 6 − 2.5 = 3.5%. That is, the rupee should depreciate by 3.5%relative to the dollar.b. The nominal dollar return for the U.S. institutional investor is approximately 12 − 5 = 7%. Thereal return for the U.S. investor is approximately 7 − 2.5 = 4.5%. The real return for the Indianinvestor is approximately 12 − 6 = 6%. Thus, the U.S. investor has a lower real return than theIndian investor. This is so because the rupee depreciated with respect to the dollar by more thanwhat the PPP relationship would indicate. Indeed, the difference between the real returns is6 − 4.5 = 1.5%, which is the same as the difference between the actual depreciation of the rupeeand the depreciation that should have occurred as per PPP (5 − 3.5 = 1.5%).7. If a country’s currency is undervalued, it means that the real prices of assets in this country are lowcompared with other countries. Also, the wages are lower in real terms than in other countries. Thus, investors from other countries would invest in this country to take advantage of low prices andwages. This action would help in the appreciation of the undervalued currency and restoration of the PPP in the long run. In terms of foreign trade, an undervalued currency implies that exports from this country would get a boost while imports would become less attractive. This would also help in the appreciation of the undervalued currency and restoration of the PPP in the long run.8. In risk-neutral efficient foreign exchange markets, the forward rate is the expected value of the futurespot rate. The forward rate can be computed using the interest rate parity relation. Because the exchange rate is given in $:SFr terms, the appropriate expression for the interest rate parity relation isSFr $11r F Sr +=+ (that is, r SFr is a part of the numerator and r $ is a part of the denominator). Accordingly, the three-month forward rate is10.00951.4723 1.460010.0180F +==+ thus, the implied market prediction for the three-month ahead exchange rate is SFr1.4600 per $.9. As per the model, one € would be worth $0.9781 six months later. Based on the forward rate, one €would be worth $0.9976 six months later. Therefore, the market participants, who believe that the model is quite good, would buy the dollar in the forward market (sell euros). Consequently, the price of the euro forward would decrease (the dollar forward would increase) and the forward rate would become equal to $0.9781 per €. The spot exchange rate and the dollar and euro interest rates would change so as to be consistent with this forward rate. A look at the interest rate parity relationship— written in the form€$11r F S r+=+ as F and S are in €:$ terms—suggests that with the decrease in forward rate from $0.9976 per € to$0.9781 per €, the spot rate and interest rate in dollars are likely to go down and interest rate in euros is likely to go up.16 Solnik/McLeavey • Global Investments, Sixth Edition10. a. The forward rate can be computed using the interest rate parity relation. Because the exchange rate is given in £:$ terms, the appropriate expression for the interest rate parity relation is$£11r F S r +=+ (that is, r $ is a part of the numerator, and r £ is a part of the denominator). Accordingly, the one-year forward rate is1.02001.5620$1.5283 per £1.0425F .== b. Based on the forward rate, one pound would be worth $1.5283 one year later. The model predictsthat one pound would be worth $1.5315 one year later. Thus, as per the model, the pound isunderpriced in the forward market. Accordingly, Dustin Green would buy pounds forward at$1.5283/£.c. If everyone were to buy pounds forward, the price of pounds forward would increase and becomeequal to $1.5315 per £. The spot exchange rate and the dollar and pound interest rates wouldchange so as to be consistent with this forward rate. A look at the interest rate parity relationship suggests that the spot rate and the interest rate in dollars are likely to go up and the interest rate in pounds is likely to go down, to be consistent with the increase in the forward rate.11. a. If the market participants are risk-neutral, the expected future spot exchange rate would be thesame as the current forward rate. The forward rate is determined based on the current spotexchange rate and the interest rate differential between the two currencies. Thus, the expectedfuture spot exchange rate would depend on the current spot exchange rate and the interest ratedifferential.b. If the market participants are risk-averse, the forward rate would differ from the expected futurespot exchange rate by the risk premium. The risk premium, based on the extent of risk aversionof the market participants, could be positive or negative. So, the expected future spot exchangerate is the forward rate less the risk premium. Since the forward rate is based on the current spot exchange rate and the interest rate differential between the two currencies, the expected futurespot exchange rate would depend on the current spot exchange rate, the interest rate differential, and the risk premium.12. There is some evidence of positive serial correlation in exchange rate movements (real and nominal).Hence, when a currency is going up, a reasonable forecast is that it will continue going up. Similarly, when a currency is going down, a reasonable forecast is that it will continue going down. However, at some point in time, the trend would reverse, and the problem is that a trend-based forecasting model cannot forecast when this turning point would occur. Although these turning points may be infrequent, they can be the occasion of a huge swing. The Mexican peso is a good example. For a few years until the end of 1994, the real value of the peso appreciated steadily. So, forecasters using trendmodels for the real exchange rates were quite successful for many months. However, in December 1994, the peso suddenly crashed and lost around half of its value.13. Statements (a), (c), and (d) are true. Statement (b) is not true, because the objective of central bankactivity in the foreign exchange market is not to profit from trading activities, but to implementmonetary policy and exchange rate targets.Chapter 3 Foreign Exchange Determination and Forecasting 17 14. A mean-reverting time series is one that may diverge from its fundamental value in the short run butreverts to its fundamental value in the long run. Empirical evidence suggests that exchange rates are mean reverting. The real exchange rates (observed exchange rate minus inflation) do deviate from the fundamental value implied by PPP in the short run, but tend to revert to the fundamental value in the long run.15. Most econometric models are unsuitable for short-term exchange rate forecasts, as they model long-term structural economic relationships. For long-term exchange rate forecasts, the use of econometric models has some problems. First, most of them rely on predictions for certain key variables, such as money supply and interest rates. It is not easy to forecast these variables. Second, the structuralcorrelation estimated by the parameters of the equation can change over time, so that even if allcausative variables are correctly forecasted, the model can still yield poor exchange rate predictions.In periods when structural changes are rapid compared with the amount of time-series data required to estimate parameters, econometric models are of little help.16. Technical analysis is more likely to be used for short-term exchange rate movements, while theeconometric approach is more likely to be used for long-term exchange rate movements. The manager of a currency hedge fund and currency traders change their foreign exchange positions quite quickly, and are interested in short-term changes in exchange rates. On the other hand, the manager of an international stock portfolio is unlikely to change his foreign exchange positions quickly, because the transaction costs of buying and selling stocks are quite high. Therefore, the manager of aninternational stock portfolio is more interested in the long-term movements in exchange rates.Similarly, the long-term strategic planner of a corporation is interested in the long-term movements.Accordingly, the answers are:a. Technical analysisb. Econometric approachc. Technical analysisd. Econometric approach17. a. The absolute values of prediction errors are as follows: Forward rate: 1.440 − 1.308 = 0.132;Analyst A: 1.410 − 1.308 = 0.102; and Analyst B: 1.580 − 1.308 = 0.272. Thus, the forecast byAnalyst A was the most accurate.b. The forward rate and Analyst B erroneously predicted that the SFr to $ exchange rate would goup from the then-spot rate of SFr 1.420 per $; that is, the SFr would depreciate. Only Analyst Acorrectly predicted that the Swiss franc would appreciate.18. a. The absolute values of forecast errors are as follows: Forward rate: 148.148 − 144.697 = 3.451;Commerzbank: 148.148 − 142 = 6.148; and Harris Bank: 156 − 148.148 = 7.852. Thus, theforecast as per the forward rate was the most accurate, followed by Commerzbank, and then byHarris Bank.b. Although the forward rate and Commerzbank were more accurate than Harris Bank, both of themerroneously predicted that the yen would appreciate relative to the dollar. Only Harris Bankcorrectly predicted that the yen would depreciate.18 Solnik/McLeavey • Global Investments, Sixth Editionc. Commerzbank’s forecast was ¥142 per $, which was less than the forward rate. Therefore, DavidBrock bought yen forward (sold dollars) at the rate of ¥144.697 per $. Because the actual rateturned out to be ¥148.148 per $, buying yen forward did not turn out to be the right strategy. On the other hand, Harris Bank’s forecast was ¥156 per $, which was more than the forward rate.Therefore, Brian Lee sold yen forward (bought dollars) at the rate of ¥144.697 per $. Because the actual rate turned out to be ¥148.148 per $, selling yen forward turned out to be the right strategy. d. Commerzbank’s forecast had a lower forecast error than Harris Bank’s in Part (a). However, inPart (c), it was right to buy and sell based on Harris Bank’s forecast and not Commerzbank’s.The reason is that Harris Bank’s forecast turned out to be on the right side of the forward rate,while Commerzbank’s did not.19. Let the forecasts made by the Industrial Bank of Japan at the beginning of period t for the beginningof period t + 1 be E (S t + 1|φt ). Let the forward rates quoted at the beginning of period t for thebeginning of period t + 1 be F t , and the actual spot rates at the beginning of periods t and t + 1 be S t and S t +1, respectively. The percentage forecast errors (∈and e ) for each forecast made by the Industrial Bank of Japan and the forward rate are computed as εt +1 = [S t +1 − E (S t +1|φt )]/S t and e t +1 = [S t +1 − F t ]/S t , respectively. The following table details the computations.Pd.

international（国际经济学）课后习题及答案----------------------- Page 1-----------------------Review Questions and Condensed Answers forInternational Trade TheoriesChapter 1 World Trade and the National EconomyReview Questions::::1( What features distinguish international from domestic transactions?2( What can you say about the growth of world trade in both nominal and real terms? Was itfaster than the growth of output?3( Evaluate the statement,” the United States is a closed economy, hence foreign trade is ofno consequence to it.”4( Distinguish between export industries, import-competing industries and nontraded goods.Give examples of each.5( Using the figure in table 1-3, what can you say about the trade structure of the USA andJapan.Condensed Answers to Review Questions::::1. The text discusses ways that international transactions differfrom domestic ones.i. International trade requires that transactions be conductedbetween twocurrencies mediated by an exchange rate. Domestic transactions are conductedin a single currency.ii. Commercial policies that operate to restrict international transactions cannot, ingeneral, be imposed on domestic trade. Such policies include tariffs, quotas,voluntary export restraints, export subsidies, and exchange controls.iii. Countries pursue different domestic macroeconomic policieswhich result indivergent rates of economic growth, inflation, and unemployment.iv. More statistical data exist on the nature, volume, and value of internationaltransactions than exist in domestic trade.v. Factors of production are more mobile domestically than internationally.vi. Countries exhibit different demand patterns, sales techniques,and marketingrequirements. Many of these are due to culture and custom. Someresult fromdifferences in government regulations. Included here are health, safety,environmental, and technical rules.2. The real volume of world exports grew at an annual rate of more than 6 percent between1950 and 2000. Global output grew at an annual rate of 4 percent. Export growth inexcess of output growth reflects the increased openness to trade of many countries.3. The United States is a relatively closed economy since the share of trade in GDP issmaller than that of most other industrial nations. In 2000, U.S. exports of goods andservices were 11 percent of GDP. The U.S. economy is less dependent on the foreignsector than other major economies, but to say that foreign trade is of no consequence is anexaggeration. The U.S. economy has become increasingly open and, therefore, moreimpacted by trade developments over time. This trend is likely to continue. Curtailingimports would, for example, have a big effect on consumers' ability to buy some goods----------------------- Page 2-----------------------(e.g. tropical products) and would raise the prices of others. The absence of certain keycommodities and material inputs would greatly disrupt areas of U.S. industry.4. a. Export industries send a substantial share of their output abroad. Ratios ofexports to GDP are much higher than the average ratio for all industries. Netexporting industries are those for which exports exceed imports. U.S. netexporting industries include farm products, chemicals, certain types of machinery,and aerospace products.b. Import-competing industries are domestic industries that sharethe domesticmarket with a substantial import presence. These activities haveratios ofimports to GDP that are much higher than the average ratio for all industries.U.S. import-competing industries include fuels, automobiles,clothing, footwear,and iron and steel.c. Nontraded goods are those which, because of their nature and characteristics, arenot easily exported or imported. Examples are hair-dressing, movie theaters,meals, construction activity, and health-care.5. Table 1.3 contains figures on the trade structure of the U.S. and Japan. The U.S. is a netexporter of food, certain ores, chemicals, and other machinery and transport equipment,and is a net importer of raw materials, mining products, fuels, nonferrous metals, iron andsteel, semimanufactures, office and telecommunications equipment, automotive products,textiles and clothing, and other consumer goods. Japan is a net exporter of iron and steel,chemicals, semimanufactures, office and telecommunications equipment, automotiveproducts, other machinery and transport equipment, and other consumer goods. Importsexceed exports in food, raw materials, and textiles and clothing.----------------------- Page 3-----------------------Chapter 2 Why Nations TradeReview Questions::::1( a. In what sense are the cost data of footnote 4 related to the figures of scheme 1?b. Based on the figures of footnote 4, determine the:Direction of trade once it develops.Limits to mutually beneficial trade.Limits to a sustainable exchange trade.2. Evaluate the following statements:a. In international trade, domestic cost ratios determine the limits of mutually beneficial trade,whereas demand considerations show where, within these limits, the actual exchange ratio will lie.b. Comparative advantage is a theoretical concept. It cannot be used to explain any real-worldphenomena.c. The opening up of trade raises the price of export goods; hence trade is inflationary.d. The concept of absolute advantage offers explainations for East Germany’s high unemploymentrates in the 1990s.3. a. Use the theory of comparative advantage to explain why it pays for:The USA to export grains and import oil.Russia to export oil and import grains.b. Why does the popular press believe that grain exports are inflnationary? What is wrongwith this porposition?Condensed Answers to Review Questions:1. a. Scheme 1 is based on labor productivity comparisons, while Footnote 4presentsper unit cost data. Production cost ratios are inversely related to productivitymeasures.b. i. Textiles will be exported from the U.K. and wheat from the U.S.ii. The U.S. will trade only if one yard of textiles costs less than3 bushels ofwheat. The U.K. will trade only if 1 yard of textiles can be exchangedfor more than 2 bushels of wheat.iii. The value of the ? must be between $1 and $1.502. a. Consider Figure 2.2. The domestic cost ratios define limits of mutually beneficialtrade. Within the region of mutually beneficial trade the actual exchange rate willbe determined by the relative intensity of each country's demand for the othercountry's product. A full analysis requires an understanding of reciprocal demandcurves, but the following general principle might help heuristically. If the Britishare more eager to buy U.S. wheat than the Americans are eager for British textiles,the exchange ratio falls close to the U.K. domestic cost ratio and the U.S. can beviewed as capturing a greater share of the gains from trade.b. Since the real world does not conform to the convenienttwo-country, two-goodassumptions, the simple theoretical model is not immediately applicable.However, we can generalize the model to many goods and many nations. Thefundamental truth remains. Countries export those goods in which their relativeproduction costs are lower and import those goods for which the relative costs arehigher.----------------------- Page 4-----------------------c. While trade tends to raise the prices of exportables in the domestic economy, theeffect of trade is to lower the average price level of all goods. Trade givesconsumers an opportunity to consume at lower world prices. Many goods will becheaper when purchased from foreign supply sources. Trade also conveysprocompetitive effects, stimulates the adoption of new technologies, and allowsfirms to achieve efficient scale production levels. Thus, trade is anti-inflationary.d. The reunification of the Germany economy in 1990 was undertaken on the basisthat a unit of the deutschmark, the West German currency, should be equal in valueto a unit of the ostmark, the East German currency. At this exchange rate, goodsproduced in East Germany were almost universally more expensive to producethan their counterparts in the West. Labor productivity in East Germanmanufacturing was found to be about 35% of the West German level. Underthese conditions the East German manufacturing sector collapsed. Investors werereluctant to purchase East German factories and large scale closures and dismissalsresulted.3. a. The U.S. enjoys a comparative advantage in grains. It also produces oil, but will gain byspecializing in grain production and using proceeds of exported agriculturalproducts to purchase oil from nations that produce oil relatively more efficiently.Russia is relatively more efficient in the production of oil and will gain bypurchasing grain from the U.S. in exchange for oil.b. The popular press asserts that by exporting grain from the U.S. (say to the former U R)we are lowering the domestic supply of grain and raising the domestic U.S. price of grain. Sincegrain is an important ingredient in many food products, grain exports are believed to increase theprice of those products. However, the price of grain is determined in world markets. U.S.exports alone cannot permanently raise the domestic U.S. price. If the domestic U.S. grainpricerose above the world price, the U.S. would be a net importer of grains and the domestic price wouldfall.----------------------- Page 5-----------------------Chapter 3 The Commodity Composition of TradeReview Questions::::1( Does the factor proportions theory provide a good explanation of intraindustry trade? Ifnot, can you outline an alternative explaination for the growing phenomenon?2( Explain the dynamic nature of comparative advantage using Japan’s experience as anexample.3( Once the United States acquires a comparative advantage in jet aircraft production it canbe sure of a dominant position in the global market forever. Do you agree with thisstatement? Explain.Condensed Answers to Review Questions1. The factor proportions theory is better suited to explain interindustry trade, or the exchangebetween countries of totally different commodities, than intraindustry trade, which is thetwo-way trade of similar commodities. The growth of intraindustry trade is greatest inimperfectly competitive industries characterized by economies of scale. Here, scaleeconomies force firms in each industry to specialize in a narrow range of products withineach industry to achieve efficient scale operations. Intraindustry specialization combinedwith diverse consumer tastes gives rise to two-way trade within the same industryclassification.2. Japan's comparative advantage in the immediate post-war period was in labor intensivegoods. The high level of saving and investment transformed Japan into a relatively capitalabundant country. Its advantage in the labor-intensive industries was lost as wages rose.Moreover, Japan increased its technological capability through high spending on R&D.Now Japan's advantage lies in the production of high-tech, capital intensive goods similar tothe U.S. This in large part explains the increasing trade friction between the twocountries.3. Once the U.S. acquires a comparative advantage in jet aircraft, it is likely to enjoy a dominantposition in the global marketplace for years, but not forever. Jet aircraft production is characterizedby huge economies of scale due largely to research and development costs. High capitalrequirements and scale economies pose large entry barriers. It is extremely difficult for a countryto enter into aircraft production once the U.S. has the lead. The new firm would initially have asmall market share and would be unable to compete on a cost basis. The new market entrant wouldrequire considerable government support and encouragement. This was the case with the EuropeanAirbus.----------------------- Page 6-----------------------Chapter 4 Protection of Domestic Industries: The TariffReview Questions::::1( A tariff on textiles is equivalent to a tax on consumers and a subsidy to the textileproducers and workers.2( Explain the concept of effective rate of protection.a. What does the effective rate on final goods depend upon and how?b. In what way does the effective rate analysis help to illuminate these policy issues:Deepening of production in LDCsEscalation of tariff rates by degree of processing in industrial countries3. A tariff lowers the real income of the country, while at the same time it distributes income fromconsumers to the governments and to the import-competing industry.Condensed Answers to Review Questions:1. The effect of a tariff is comparable to the combined effects of a tax on consumers and a subsidy toproducers. Using Figure 4.3, one can show a tariff results in a transfer of resources from theconsumers (who lose P P fd ) to the producers (who gain P P ec). With a non-prohibitive tariff, the2 3 2 3government will also gain revenue efmn. Whether the two schemes are equivalent depends on theexact nature of the tax and subsidy scheme.2. a. The effective rate of protection measures the percentage increase in domesticvalue added per unit of output made possible by tariffs on the output and onmaterial inputs. Determinants of the effective rate include thetariff on the finalproduct, tariffs on the imported material inputs, and the free trade value added perunit of output which is influenced by intermediate input coefficients. Effectiverates are positively related to the tariff on the final product and negatively related toboth tariffs on imported inputs and the free trade value added. A derivation ofthe formula appears in footnote 10, and footnote 12 interprets that formula.b. "Deepening" of production in LDCs involves import substitution industrializationpolicy. A final assembly plant is given a protective tariff and imported inputs areaccorded duty free treatment. As a second stage, the LDC begins to deepenproduction by manufacturing inputs and according them protection. By imposingtariffs on imported inputs, the LDC is reducing effective protection for the finalgood.Because of relatively high rates of protection on finished goods and low protectionon unfinished goods and raw materials, effective tariff rates in developed countriesmay be as much as double their nominal counterparts. Developing countriesmaintain that such tariff structures fatally harm their efforts to increase exports offinished manufactures.3. Again using Figure4.3, the loss in real income is shown by triangles cen and mfd.Redistribution has been given in 8a.----------------------- Page 7-----------------------Chapter 5 Nontariff Barriers (NTBs) to TradeReview Question::::Suppose the USA steel industry is seeking protection from foreign imports. Compare andcontrast the following measures of restricting steel industries: a tariff, a quota, and voluntaryexport restraints.Condensed Answers to Review Question:There are a variety of ways in which a tariff may be considered to be less harmful than an equivalentquota:i. The revenue effect. Tariffs provide revenue. Quotas do not automatically providerevenue. Under a quota, revenue accrues to holders of import licenses.Depending on the quota scheme, licenses may be held by domestic importers, foreign exporters, foreign governments, or domestic officialswho may use them to encourage bribery. Only through auctioning or selling licenses can the government capture quota rents.ii. Performance under demand and supply changes. Any amount of imports can enterunder a tariff, but with a quota import volumes are fixed. When demandgrows, or there is a shortfall in supply, the quota does not permit a quantityadjustment. The domestic price can depart significantly from the worldprice. Under a tariff, the domestic price cannot rise above the worldprice by more than the tariff rate. Thus, a tariff is less harmful than aquota.iii. Impact on Exporters. When a tariff is levied on an imported good it is usually rebatedwhen the good is exported. The same is not true for a quota. Quotas maytherefore be more harmful to export performance.iv. Curbing monopoly power. Quotas curtail monopoly power less than an equivalent tariff.v. Terms of Trade Effects. Quotas provide no incentive for exporting nations to absorb partof the price increase; tariffs do if the exporting nation wishes to retainmarket share.vi. Quality Upgrading. Quotas give an incentive for the exporting country to engage in qualityupgrading. Ad valorem tariffs do not provide an incentive for this behavior but specific duties do.VERs share all of the undesirable effects of quotas. When the exporter does the restricting, there isno opportunity to sell import licenses. Quota rents accrue toforeign exporters orgovernments under a VER. Therefore, VERs are more costly to society than anequivalent quota with licenses sold or a tariff. Quantitative restrictions like VERsare discriminatory. VERs are also hard to monitor. Since shipments from thirdparty countries are unrestricted, transshipment throughnonrestricted countries is amajor problem. One advantage of VERs is they do not invite retaliation sincethey are profitable to foreign exporters and governments.Tariffs, quotas and VERs may be equivalent in terms of effects on the domestic price and thevolumeof imports. This may be shown using diagram 5-1. However, there are important differencesdiscussed in 1a. above.----------------------- Page 8-----------------------Chapter 6 International and Regional Trade Organizations Among Developed CountriesReview Questions::::1. Explain the following terms:Trade creation of a customs union.Trade diversion of a customs union.2.What are the conflicts between the WTO and the environmental movement?Condensed Answers to Review Questions:1. Trade creation refers to the replacement of high cost production in each member by importsfrom another member. This effect is favorable to world welfare. Tradediversion is the diversion of trade from a nonmember to a higher cost member.This is unfavorable because it reduces worldwide resource allocative efficiency(See Figure 4-8).The basic approach to calculating welfare effects associated with customs union formation is toconstruct hypothetical estimates of what member country trade patterns wouldhave been in the absence of integration, comparing these with actual trade flows,and attributing any difference to integration. Effects ofintegration can be isolatedby using trade flow data pertaining to nonmember "normalizer" countries over thesame period to suggest what trade patterns would have been expected for memberswithout integration. Assume, in the absence of integration, both total (internalplus external) and external member imports would have grown at the same rates asthe corresponding imports in the normalizer. The normalizer's external importsrefer to its imports from third countries (i.e. intra-trade is excluded). Thenormalizer's internal imports are imports of normalizer countries from each other(e.g. intra-trade). The preintegration member country total import level ismultiplied by the corresponding normalizer import growth rate to yield an estimateof hypothetical total imports without integration. When compared with actualtotal imports, an estimate of trade creation is obtained. Trade diversion isestimated by multiplying the member country preintegration external import levelby the normalizer's rate of change of external imports to yield hypothetical membercountry external imports. The excess of hypothetical over actual external importsconstitutes trade diversion. The European Union (EU) is a customs unioncomprised of 15 West European countries.2. WTO rules often conflict with both international environmental agreements and nationalenvironmental laws. For example, a 1991 GATT panel upheld a Mexican challenge to aU.S. law banning importation of tuna caught indolphin-killing purse-seine nets.GATT/WTO provisions are concerned with products and not production methods.----------------------- Page 9-----------------------Chapter 7 International Mobility of Productive FactorsReview Question::::What is the meaning of DFI?

It may be the purchase of an existing company, a substantial part of itsshares, or the establishment of a new enterprise. It should be contrasted with portfolio investmentthat gives, by and large, no control over foreign assets.The motives are diverse and any particular investment may involve one or more of the followingi. investment in extractive industries to secure raw material supplies;ii. investment in manufacturing industry to take advantage of cheaper foreign labor;iii. to locate production close to foreign markets and avoid transportation costs;iv. to take advantage of incentives offered by host countries;v. to circumvent tariff barriers;vi. changes in the exchange values of currencies; andvii. marketing considerations.。

CHAPTER 7 FUTURES AND OPTIONS ON FOREIGN EXCHANGESUGGESTED ANSWERS AND SOLUTIONS TO END-OF—CHAPTERQUESTIONS AND PROBLEMSQUESTIONS1。
Explain the basic differences between the operation of a currency forward market and a futures market.Answer: The forward market is an OTC market where the forward contract for purchase or sale of foreign currency is tailor-made between the client and its international bank. No money changes hands until the maturity date of the contract when delivery and receipt are typically made. A futures contract is an exchange-traded instrument with standardized features specifying contract size and delivery date。
Futures contracts are marked-to—market daily to reflect changes in the settlement price。
Delivery is seldom made in a futures market。
Rather a reversing trade is made to close out a long or short position。

I would cover sections 1-4 in the first lecture. The most difficult part is Section 4 on themeaning and measurement of consumer and producer surplus. Since a clear understanding of the meaning and measurement of consumer and producer surplus is crucial in measuring the welfare effect of tariffs, I would explain these concepts very carefully.2. I would cover sections 5 and 6 in the second lecture. These are the most difficult sections inthe chapter and also the most important.3. The theory of tariff structure is also difficult and important. I found that the best way toexplain it is by using the simple example in the text on the suit with and without imported inputs. This section is likely to generate a great deal of discussion about the trade relations between developed and developing nations. If you do not plan to cover optional Chapter 8 on growth and development, you could spend a bit more time on this topic here , even though it will come up again in Chapter 6.Answer to Problems1. a. See Figure 1 on the next page.b. Consumption is 70X, production is 50X and imports are 20X.c. The consumption effect is –30X, the production effect is +30X, the trade effectis –60X, and the revenue effect is $30 (see Figure 1).2. a. The consumer surplus is $250 without and $l22.50 with the tariff (see Figure 1).b. Of the increase in the revenue of producers with the tariff (as compared with theirrevenues under free trade), $22.50 represents the increase in production costs andanother $22.50 represents the increase in rent or producer surplus (see Figure 1).c. The dollar value or the protection cost of the tariff is $45 (see Figure 1).3. The dollar value or the protection cost of the tariff is $45 (see Figure 2).4. The dollar value or the protection cost of the tariff is $45 (see Figure 3).5. The optimum tariff is the tariff that maximizes the net benefit resulting from theimprovement in the nation’s terms of trade against the negative effect resulting fromreduction in the volume of trade.X Fig 5.1X Fig 5.2XFig 5.36. a. When a nation imposes an optimum tariff, the trade partner’s welfare declines because ofthe lower volume of trade and the deterioration in its terms of trade.b. The trade partner is likely to retaliate and in the end both nations are likely to lose becauseof the reduction in the volume of trade.7. Even when the trade partner does not retaliate when one nation imposes the optimum tariff,the gains of the tariff-imposing nation are less than the losses of the trade partner, so that theworld as a whole is worse off than under free trade. It is in this sense that free trade maximizesworld welfare.8. a. The nominal tariff is calculated on the market price of the product or service. The rate ofeffective protection, on the other hand, is calculated on the value added in the nation. It isequal to the value of the price of the commodity or service minus the value of the importedinputs used in the production of the commodity or service.b. The nominal tariff is important to consumers because it determines by how much the priceof the imported commodity increases. The rate of effective protection is important fordomestic producers because it determines the actual rate of protection provided by thetariff to domestic processing.9. a. Rates of effective protection in industrial nations are generally much higher than thecorresponding nominal rates and increase with the degree of processing.b. The tariff structure of developed nations is of great concern for developing nationsbecause it discourages manufacturing production in developing nations.10. If a nation reduces the nominal tariff on the importation of the raw materials required toproduce a commodity but does not reduce the tariff on the importation of the finalcommodity produced with the imported raw material, then the effective tariff rates willincrease relative to the nominal tariff rate on the commodity.Multiple-choice Questions1. Which of the following statements is incorrect?a. an ad valorem tariff is expressed as a percentage of the price of the traded commodity.b. a specific tariff is expressed as a fixed sum of the value of the traded commodity.c. export tariffs are prohibited by the U.S. Constitution*d. the U.S. uses exclusively the specific tariff2.

If a small nation increases the tariff on its import commodity, its:a. consumption of the commodity increasesb. production of the commodity decreasesc. imports of the commodity increase*d. none of the above4. The increase in producer surplus when a small nation imposes a tariff is measured by the area: *a. to the left of the supply curve between the commodity price with and without the tariffb. under the supply curve between the quantity produced with and without the tariffc. under the demand curve between the commodity price with and without the tariffd. none of the above.5. If a small nation increases the tariff on its import commodity:*a. the rent of domestic producers of the commodity increasesb. the protection cost of the tariff decreasesc. the deadweight loss decreasesd. all of the above6. The imposition of an optimum tariff by a small nation:a. improves its terms of tradeb. reduces the volume of tradec. increases the nation's welfare*d. non of the above7. The optimum tariff for a small nation is:a. 100%b. 50%*c. 0d. depends on the elasticity of demand and supply for the import commodity in the nation8. The imposition of an optimum tariff by a large nation:a. improves its terms of tradeb. reduces the volume of tradec. increases the nation's welfare*d. all of the above9. The imposition of an optimum tariff by a large nation:a. improves the terms of trade of the trade partner*b. reduces the volume of tradec. increases the trade partner’s welfared. all of the above10.

CHAPTER 13 INTERNATIONAL EQUITY MARKETSSUGGESTED ANSWERS AND SOLUTIONS TO END-OF-CHAPTERQUESTIONS AND PROBLEMSQUESTIONS1. Get a current copy of The Wall Street Journal and find the Dow Jones Country Indexes listing in Section C of the newspaper. Examine the year-to-date percentage changes in U.S. dollars for the various national indexes. How do the changes from your table compare with the year-to-date percentage changes from the sample provided in the textbook as Exhibit 13.8? Are the same national indexes positive and negative in both listings? Discuss your findings.Answer: This question is designed to provide an intuitive understanding of the benefits from international diversification of equity portfolios. It is very unlikely that the student will find many, if any, national market indexes that have year-to-date returns that are even close to the same level as in Exhibit 13.8. Over different time periods, different market forces will affect each national market in unique ways and the exchange rates will be different. Some markets that previously yielded a positive return will now show a negative return, and vice versa. Similarly, some markets that had yielded a large positive (negative) return may now show only a small positive (negative) return.2. As an investor, what factors would you consider before investing in the emerging stock market of a developing country?Answer: An investor in emerging market stocks needs to be concerned with the depth of the market and the market’s liqui dity. Depth of the market refers to the opportunities to invest in the country. One measure of the depth of the market is the concentration ratio of a country’s stock market. The concentration ratio frequently is calculated to show the market value of the ten largest stock traded as a fraction of the total market capitalization of all equities traded. The higher the concentration ratio, the less deep is the market. That is, most value is concentrated in only a few companies. While this does not necessarily imply that the largest stocks in the emerging market are not good investments, it does, however, suggest that there are few opportunities for investment in that country and that proper diversification within the country may be difficult. In terms of liquidity, an investor would be wise to examine the market turnover ratio of the country’s stock market. High market turnover suggests that the market is liquid, or that there are opportunities for purchasing or selling the stock quickly at close to thecurrent market price. This is important because liquidity means you can get in or out of a stock position quickly without spending more than you intended on purchase or receiving less than you expected on sale.3. Compare and contrast the various types of secondary market trading structures.Answer: There are two basic types of secondary market trading structures: dealer and agency. In a dealer market, the dealer serves as market maker for the security, holding an inventory of the security. The dealer buys at his bid price and sells at his asked price from this inventory. All public trades go through the dealer. In an agency market, public trades go through the agent who matches it with another public trade. Both dealer and agency markets can be continuous trade markets, but non-continuous markets tend to be only agency markets. Over-the-counter trading, specialist markets, and automated markets are types of continuous market trading systems. Call markets and crowd trading are each types of non-continuous trading market systems. Continuous trading systems are desirable for actively traded issues, whereas call markets and crowd trading offer advantages for smaller markets with many thinly traded issues because they mitigate the possibility of sparse order flow over short time periods.4. Discuss any benefits you can think of for a company to (a) cross-list its equity shares on more than one national exchange, and (b) to source new equity capital from foreign investors as well as domestic investors.Answer: A MNC that has a product market presence or manufacturing facilities in several countries may cross-list its shares on the exchanges of these same countries because there is typically investor demand for the shares of companies that are known within a country. Additionally, a company may cross-list its shares on foreign exchanges to broaden its investor base and therefore to increase the demand for its stock. An increase in demand will generally increase the stock price and improve its market liquidity. A broader investor base may also mitigate the possibility of a hostile takeover. Additional, cross-listing a company’s shares establishes name recognition and thus facilitates sourcing new equity capital in these foreign capital markets.5. Why might it be easier for an investor desiring to diversify his portfolio internationally to buy depository receipts rather than the actual shares of the company?Answer: A depository receipt can be purchased on the investor’s domestic exchange. It represents a package of the underlying foreign security that is priced in the investor’s local currency and in a trading range that is typical for the investor’s marketplace. The investor can purchase a depository receipt directly from his domestic broker, rather than having to deal with an overseas broker and the necessity of obtaining foreign funds to make the foreign stock purchase. Additionally, dividends are received in the local currency rather than in foreign funds that would need to be converted into the local currency.6. Why do you think the empirical studies about factors affecting equity returns basically showed that domestic factors were more important than international factors, and, secondly, that industrial membership of a firm was of little importance in forecasting the international correlation structure of a set of international stocks?Answer: While national security markets have become more integrated in recent years, there is still a tremendous amount of segmentation that brings about the benefit to be derived from international diversification of financial assets. Monetary and fiscal policies differ among countries because of different economic circumstances. The economic policies of a country directly affect the securities traded in the country, and they will behave differently than securities traded in another country with other economic policies being implemented. Hence, it is not surprising that domestic factors are found to be more important than international factors in affecting security returns. Similarly, industrial activity within a country is also affected by the economic policies of the country; thus firms in the same industry group, but from different countries, will not necessarily behave the same in all countries, nor should we expect the securities issued by these firms to behave alike.PROBLEMS1. On the Milan bourse, Fiat stock closed at EUR5.84 per share on Thursday, March 3, 2005. Fiat trades as and ADR on the NYSE. One underlying Fiat share equals one ADR. On March 3, the $/EUR spot exchange rate was $1.3112/EUR1.00.a. At this exchange rate, what is the no-arbitrage U.S. dollar price of one ADR?b. By comparison, Fiat ADRs closed at $7.61. Do you think an arbitrage opportunity exists?Solution:a. The no-arbitrage ADR U.S. dollar price is: EUR5.84 x $1.3112 = $7.66.b. It is unlikely that an arbitrage opportunity exists after transaction costs. Additionally the slight difference in prices is likely accounted for by a difference in information contained in prices since the ADR market in New York closed several hours after the Milan bourse.2. If Fiat ADRs were trading at $7 when the underlying shares were trading in Milan at EUR5.84, what could you do to earn a trading profit? Use the information in problem 1, above, to help you and assume that transaction costs are negligible.Solution: As the solution to problem 1 shows, the no-arbitrage ADR U.S. dollar price is $7.66. If Fiat ADRs were trading at $7, a wise investor would buy the relatively undervalued ADRs. Since the ADRs are a derivative security, one would expect the ADRs to increase in price from $7 to $7.66. Assuming this happens, the position could be liquidated for a profit of $7.66 - $7.00 = $0.66 per ADR.MINI CASE: SAN PICO’S NEW STOCK EXCHANGESan Pico is a rapidly growing Latin American developing country. The country is blessed with miles of scenic beaches that have attracted tourists by the thousands in recent years to new resort hotels financed by joint ventures of San Pico businessmen and moneymen from the Middle East, Japan, and the United States. Additionally, San Pico has good natural harbors that are conducive for receiving imported merchandise from abroad and exporting merchandise produced in San Pico and other surrounding countries that lack access to the sea. Because of these advantages, many new businesses are being started in San Pico.Presently, stock is traded in a cramped building in La Cobijio, the nation’s capital. Admittedly, the San Pico Stock Exchange system is rather archaic. Twice a day an official of the exchange will call out the name of each of the 43 companies whose stock trades on the exchange. Brokers wanting to buy or sell shares for their clients then attempt to make a trade with one another. This crowd trading system has worked well for over one hundred years, but the government desires to replace it with a new modern system that will allow greater and more frequent opportunities for trading in each company, and will allow for trading the shares of the many new start-up companies that are expected to trade in the secondary market. Additionally, the government administration is rapidly privatizing many state-owned businesses in an attempt to foster their efficiency, obtain foreign exchange from the sale, and convert the country to a more capitalist economy. The government believes that it could conduct this privatization faster and perhaps at more attractive prices if it had a modern stock exchange facility where the shares of the newly privatized companies will eventually trade.You are an expert in the operation of secondary stock markets and have been retained as a consultant to the San Pico Stock Exchange to offer your expertise in modernizing the stock market. What would you advise?S uggested Solution to San Pico’s New Stock ExchangeMost new and renovated stock exchanges are being established these days as either a partially or fully automated trading system. A fully automated system is especially beneficial for a small to medium size country in which there is only moderate trading in most issues. Such a system that deserves special note is the continuous National Integrated Market system of New Zealand. This system is fully computerized and does not require a physical structure. Essentially, all buyers and sellers of a stock enter through their broker into the computer system the number of shares they desire to buy or sell and their required transaction price. The system is updated constantly as new purchase or sale orders are entered into the system. The computer constantly searches for a match between buyer and seller, and when one is found a transaction takes place. This type of system would likely serve San Pico’s needs very well. There is existing technology to implement, the bugs have been worked out in other countries, and it would satisfy all the demands of the San Pico government and easily accommodate growth in market activity.。

Suggested answers to questions and problems(in the text)2. a. The euro is expected to appreciate at an annual rate of approximately ((1.005 -1.000)/1.000)⋅(360/180)⋅100 = 1%. The expected uncovered interestdifferential is approximately 3% + 1% - 4% = 0, so uncovered interest parityholds (approximately).b. If the interest rate on 180-day dollar-denominated bonds declines to 3%, thenthe spot exchange rate is likely to increase—the euro will appreciate, thedollar depreciate. At the initial current spot exchange rate, the initial expected future spot exchange rate, and the initial euro interest rate, the expecteduncovered interest differential shifts in favor of investing in euro-denominated bonds (the expected uncovered differential is now positive, 3% + 1% - 3% =1%, favoring uncovered investment in euro-denominated bonds. The increased demand for euros in the spot exchange market tends to appreciate the euro. Ifthe euro interest rate and the expected future spot exchange rate remainunchanged, then the current spot rate must change immediately to be$1.005/euro, to reestablish uncovered interest parity. When the current spotrate jumps to this value, the euro's exchange rate value is not expected tochange in value subsequently during the next 180 days. The dollar hasdepreciated immediately, and the uncovered differential then again is zero (3% + 0% - 3% = 0).4. a. For uncovered interest parity to hold, investors must expect that the rate ofchange in the spot exchange-rate value of the yen equals the interest ratedifferential, which is zero. Investors must expect that the future spot value isthe same as the current spot value, $0.01/yen.b. If investors expect that the exchange rate will be $0.0095/yen, then theyexpect the yen to depreciate from its initial spot value during the next 90 days.Given the other rates, investors tend to shift their investments towarddollar-denominated investments. The extra supply of yen (and demand fordollars) in the spot exchange market results in a decrease in the current spotvalue of the yen (the dollar appreciates). The shift to expecting that the yenwill depreciate (the dollar appreciate) sometime during the next 90 days tends to cause the yen to depreciate (the dollar to appreciate) immediately in thecurrent spot market.6. The law of one price will hold better for gold. Gold can be traded easily sothat any price differences would lead to arbitrage that would tend to push gold prices (stated in a common currency by converting prices using marketexchange rates) back close to equality. Big Macs cannot be arbitraged. If price differences exist, there is no arbitrage pressure, so the price differences canpersist. The prices of Big Macs (stated in a common currency) vary widelyaround the world.}8. According to PPP, the exchange rate value of the DM (relative to the dollar)has risen since the early 1970s because Germany has experienced lessinflation than has the United States—the product price level has risen less inGermany since the early 1970s than it has risen in the United States.According to the monetary approach, the German price level has not risen asmuch because the German money supply has increased less than the moneysupply has increased in the United States, relative to the growth rates of realdomestic production in the two countries. The British pound is the oppositecase—more inflation in Britain than in the United States, and higher moneygrowth in Britain.10. a. Because the growth rate of the domestic money supply (M s) is two percentagepoints higher than it was previously, the monetary approach indicates that theexchange rate value (e) of the foreign currency will be higher than it otherwise would be—that is, the exchange rate value of the country's currency will belower. Specifically, the foreign currency will appreciate by two percentagepoints more per year, or depreciate by two percentage points less. That is, thedomestic currency will depreciate by two percentage points more per year, orappreciate by two percentage points less.b. The faster growth of the country's money supply eventually leads to a fasterrate of inflation of the domestic price level (P). Specifically, the inflation ratewill be two percentage points higher than it otherwise would be. According to relative PPP, a faster rate of increase in the domestic price level (P) leads to a higher rate of appreciation of the foreign currency.12. a. For the United States in 1975, 20,000 = k⋅100⋅800, or k = 0.25.For Pugelovia in 1975, 10,000 = k⋅100⋅200, or k = 0.5.b. For the United States, the quantity theory of money with a constant kmeans that the quantity equation with k = 0.25 should hold in 2008: 65,000= 0.25⋅260⋅1,000. It does. Because the quantity equation holds for both yearswith the same k, the change in the price level from 1975 to 2008 is consistentwith the quantity theory of money with a constant k. Similarly, for Pugelovia, the quantity equation with k = 0.5 should hold for 2008, and it does (58,500 =0.5⋅390⋅300).14.a. The tightening typically leads to an immediate increase in the country'sinterest rates. In addition, the tightening probably also results in investors'expecting that the exchange-rate value of the country's currency is likely to be higher in the future. The higher expected exchange-rate value for the currency is based on the expectation that the country's price level will be lower in thefuture, and PPP indicates that the currency will then be stronger. For both ofthese reasons, international investors will shift toward investing in thiscountry's bonds. The increase in demand for the country's currency in the spot exchange market causes the current exchange-rate value of the currency toincrease. The currency may appreciate a lot because the current exchange rate must "overshoot" its expected future spot value. Uncovered interest parity isreestablished with a higher interest rate and a subsequent expecteddepreciation of the currency.b. If everything else is rather steady, the exchange rate (the domestic currencyprice of foreign currency) is likely to decrease quickly by a large amount.After this jump, the exchange rate may then increase gradually toward itslong-run value—the value consistent with PPP in the long run.。

The Law of One Price states that in a competitive market, if two assets are equivalent they will tend to have thesame price. The law is enforced by a process called arbitrage, the purchase and immediate sale of equivalent assets in order to earn a sure profit from a difference in their prices.? Even if arbitrage cannot be carried out in practice to enforce the Law of One Price, unknown asset values canstill be inferred from the prices of comparable assets whose prices are known.? The quantitative method used to infer an asset’s value from information about the prices of comparable assets iscalled a valuation model. The best valuation model to employ varies with the information available and the intended use of the estimated value. ? The book value of an asset or a liability as reported in a firm’s financial statements often differs from its currentmarket value.? In making most financial decisions, it is a good idea to start by assuming that for assets that are bought and soldin competitive markets, price is a pretty accurate reflection of fundamental value. This assumption is generally warranted precisely because there are many well-informed professionals looking for mispriced assets who profit by eliminating discrepancies between the market prices and the fundamental values of assets. The proposition that an asset’s current price fully reflects all publicly-available information about future economic fundamentals affecting the asset’s value is known as the Efficient Markets Hypothesis.? The prices of traded assets reflect information about the fundamental economic determinants of their value.Analysts are constantly searching for assets whose prices are different from their fundamental value in order to buy/sell these “bargains.〞 In deciding the best strategy for the purchase/sale of a “bargain,〞 theanalyst has to evaluate the accuracy of her information. The market price of an asset reflects the weighted average of all analysts opinions with heavier weights for analysts who control large amounts of money and for those analysts who have better than average information.Instructor’s ManualChapter 7 Page 106Solutions to Problems at End of ChapterLaw of One Price and Arbitrage1. IBX stock is trading for $35 on the NYSE and $33 on the Tokyo Stock Exchange. Assume that the costs of buying and selling the stock are negligible. a. How could you make an arbitrage profit?b. Over time what would you expect to happen to the stock prices in New York and Tokyo?c. Now assume that the cost of buying or selling shares of IBX is 1% per transaction. How does this affectyour answer?SOLUTION:a. Buy IBX stock in Tokyo and simultaneously sell them in NY. Your arbitrage profit is $2 per share.b. The prices would converge.c. Instead of the prices becoming exactly equal, there can remain a 2% discrepancy between them, roughly $.70 inthis case.2. Suppose you live in the state of Taxachusetts which has a 16% sales tax on liquor. A neighboring state called Taxfree has no tax on liquor. The price of a case of beer is $25 in Taxfree and it is $29 in Taxachusetts.a. Is this a violation of the Law of One Price?b. Are liquor stores in Taxachusetts near the border with Taxfree going to prosper?SOLUTION:a. This is not a violation of the Law of One Price because it is due to a tax imposed in one state but not in the other.Illegal arbitrage will probably occur, with lawbreakers buying large quantities of liquor in Taxfree and selling it in Taxachusetts without paying the tax.b. It is likely that liquor stores will locate in Taxfree near the border with Taxachusetts. Residents of both stateswill buy their liquor in the stores located in Taxfree, and liquor stores in Taxachusetts will go out of business.Triangular Arbitrage3. Suppose the price of gold is 155 marks per ounce.a. If the dollar price of gold is $100 per ounce, what should you expect the dollar price of a mark to be?b. If it actually only costs $0.60 to purchase one mark, how could one make arbitrage profits?SOLUTION:a. $100 buys the same amount of gold (1 ounce) as 155 DM, so 1 DM should cost 100/155 or $.645.b. The marks are “cheaper〞 than they should be, so the arbitrage transaction requires you to buy marks at thecheap price, use them to purchase gold, and sell the gold for dollars. Example:1. Start with $1 million, which you borrow for only enough time to carry out the arbitrage transaction.2. Use the million dollars to buy 1,666,667 marks (1,000,000 / 0.60)3. Buy 10,752.69 ounces of gold (1,666,667 / 155)4. Sell the gold for $1,075,269 (10752.69 x 100)Your risk-free arbitrage profit is $75,269.4. You observe that the dollar price of the Italian lira is $0.0006 and the dollar price of the yen is $0.01. What must be the exchange rate between lira and yen for there to be no arbitrage opportunity?SOLUTION:.0006$/lira?.06Yen/lira.01$/YenInstructor’s ManualChapter 7 Page 1075. Fill in the missing exchange rates in the following table: US dollar British pound German mark Yen US dollar $1 $1.50 $.5 $.01 British pound ￡0.67 German mark DM2.0 Japanese ￥100 Yen SOLUTION: US dollar British pound German mark Japanese Yen US dollar $1 $1.50 $.5 $.01 British pound ￡0.67 1 = .67 / 2 = .67 / 100 German mark DM2.0 = 2 / .67 1 = 2 / 100 Japanese ￥100 = 100 / .67 = 100 / 2 1 Yen US dollar British pound German mark Japanese Yen US dollar $1 $1.50 $.5 $.01 British pound ￡0.67 ￡1 ￡.33 ￡.0067 German mark DM2.0 DM3.0 DM1.0 DM.02 Japanese ￥100 ￥150 ￥50 ￥1 Yen Valuation Using Comparables6. Suppose you own a home that you purchased four years ago for $475,000. The tax assessor’s office has just informed you that they are increasing the taxable value of your home to $525,000. a. How might you gather information to help you appeal the new assessment?b. Suppose the house next door is comparable to yours except that it has one fewer bedroom. It just sold for$490,000. How might you use that information to argue your case? What inference must you make about the value of an additional bedroom?SOLUTION:a. You should retrieve as much information as you can about recent sales of comparable homes. If you canconvince the assessor’s office that your home is comparable (and the market value of the recent sales is less than $525,000) you should have a good case. You can gather the information about home sales from a real estate broker.b. The difference between your house’s assessed value and the actual market value of the home next door is$35,000 ($525,000 - $490,000). If you can convince the tax assessor’s office that the value of a bedroom is less than $35,000, then the assessor must agree that your home is worth less than $525,000. For example, if comparable sales figures show that one additional bedroom (all else reasonably equivalent) is worth only $10,000, then you should be able to argue that your home is worth $500,000 rather than $525,000.7. The P/E ratio of ITT Corporation is currently 6 while the P/E ratio of the S&P 500 is 10. What might account for the difference? SOLUTION: There are several possible reasons:? ITT may be riskier than the S&P500 either because it is in a relatively risky industry or has a relatively higherdebt ratio.? ITT’s reported earnings may be higher than they are expected to be in the future, or they may be inflated due tospecial accounting methods used by ITT.Instructor’s ManualChapter 7 Page 1088. Suppose you are chief financial officer of a private toy company. The chief executive officer has asked you to come up with an estimate for the company’s price per share. Your company’s earnings per share were $2.00 in the year just ended. You know that you should look at public company comparables, however, they seem to fall into two camps. Those with P/E ratios of 8x earnings and those with P/E ratios of 14x earnings. You are perplexed at the difference until you notice that on average, the lower P/E companies have higher leverage than the higher P/E group. The 8x P/E group has a debt/equity ratio of 2:1. The 14x P/E group has a debt/equityratio of 1:1. If your toy company has a debt/equity ratio of 1.5:1, what might you tell the CEO about your company’s equity value per share? SOLUTION:It would be reasonable to apply a P/E of 11x earnings (= (8 + 14) / 2) because your leverage is midway between the two groups. Hence, your company’s price per share would be: 11x $2.00 = $22.00 per share.9. Assume that you have operated your business for 15 years. Sales for the most recent fiscal year were $12,000,000. Net income for the most recent fiscal year was $1,000,000. Your book value is $10,500,000. A similar company recently sold for the following statistics: Multiple of Sales: 0.8x Multiple of Net Income 12x Multiple of Book Value 0.9xa. What is an appropriate range of value for your company?b. If you know that your company has future investment opportunities that are far more profitable than thecompany above, what does that say about your company’s likely valuation? SOLUTION:a. Multiple of Sales: .8x = $12 million x .8 Multiple of Net Income 12x = $1 million x 12 Multiple of Book Value .9x = $10.5 million x .9 An appropriate range might be 9 to 12 millionb. Higher end of the range = $9.6 million = $12 million = $9.45 millionEfficient Markets Hypothesis10. The price of Fuddy Co. stock recently jumped when the sudden unexpected death of its CEO was announced. What might account for such a market reaction?SOLUTION:Investors may believe that the company’s future prospects look better(i.e., either higher earnings or less risky) without the deceased CEO.11. Your analysis leads you to believe that the price of Outel’s stock should be $25 per share. Its current market price is $30.a. If you do not believe that you have access to special information about the company, what do you do?b. If you are an analyst with much better than average information, what do you do?SOLUTION:a. If you believe that the market for Outel stock is an informationally efficient one then the $30 market price(which is a weighted average of the valuations of all analysts) is the best estimate of the stock’s true value. You should question whether your own analysis is correct.b. You sell the stock because you think you have superior information. Real Interest Rate Parity12. Assume that the world-wide risk-free real rate of interest is 3% per year. Inflation in Switzerland is 2% per year and in the United States it is 5% per year. Assuming there is no uncertainty about inflation, what are the implied nominal interest rates denominated in Swiss francs and in US dollars?SOLUTION: Switzerland: (1.03 x 1.02) =1.0506 hence nominal interest rate = 5.06% US: (1.03 x 1.05) = 1 .0815 hence nominal interest rate = 8.15%Instructor’s ManualChapter 7 Page 109Integrative Problem13. Suppose an aunt has passed away and bequeathed to you and your siblings (one brother, one sister) a variety of assets. The original cost of these assets follows:ITEM COST WHEN PURCHASEDJewelry $500 by Grandmother 75 years ago House 1,200,000 10 years ago Stocks and Bonds 1,000,000 3 years ago Vintage (used) Car 200,000 2 months ago Furniture 15,000 various dates during last 40 yearsBecause you are taking a course in finance, your siblings put you in charge of dividing the assets fairly among the three of you. Before you start, your brother approaches you and says: “I’d really like the car for myself, so when you divide up the assets, just give me the car and deduct the $200,000 from my share.〞Hearing that, your sister says: “That sounds fair, because I really like the jewelry and you can assign that to me and deduct the $500 from my share.〞You have always loved your aunt’s house and its furnishings, so you would like to keep the house and the furniture.a. How do you respond to your brother and sister’s requests? Justify your responses.b. How would you go about determining appropriate values for each asset?SOLUTION:a. Because the market price of the car is close to the what your brother is willing to give up for it, your brother’srequest is reasonable. It is, however, quite possible (even likely), that the antique jewelry is worth much more today than what your relative’s grandmother paid for it in the past. Assigning only its acquisition cost to your sister’s share is quite likely a gross miscalculation. If she wants the jewelry, she should be “charged〞 an amount equal to today’s market value. It does not matter that your sister does not want to sell the jewelry for a profit, because the jewelry has VALUE even if you do not sell it. Fairness is all about equal VALUE.b. You would probably have to hire a professional appraiser for the furniture and the jewelry. You can look up thevalue of the stocks and bonds in a financial newspaper. You can estimate the value of the house by inquiring for how much similar houses in the same neighborhood have recently been sold. The car was purchased only twomonths ago, so it is probably reasonable to assume that the current market price is very close to what your distant relative paid for the car.
