The Trade Theory
Trade Based on Absolute Advantage
Absolute advantage a producer (or a country) that uses smaller amount of resources to produce one unit of a certain product has absolute advantage over one that uses more resources to produce one unit of the same product. An Example: US uses 15 units of resources to produce one bushel of tomatoes; Mexico uses 10 units of resources to produce one bushel of tomatoes
An example

Consider Mexico and the US. Suppose that each country has 240 units of resources (say labor) being used in the production of corn and tomatoes. In the absence of trade between the two countries each country uses one half of its resources to produce corn and the other half to produce tomatoes.

            Mexico    U.S.                  Mexico       U.S.           Wld
           Resouces needed
           to produce one unit                     Quantity produced
Tom. :10 hrs       15 hrs                    12               8                 20

Corn:   8 hrs        4 hrs                     15              30                45

After trade each country specializes in one of the two goods.

                     Mexico    U.S.       Total

                                OUTPUT
   Tomatoes    24           0             24
    Corn            0          60             60

Gains from trade: 4 units of  tomatoes ;         15 units of corn.

Trade Based on Comparative Advantage
A country has a comparative advantage in the production of a product over another country if it can produce that product at a lower opportunity cost relative to the other country. Even if a country is less efficient in the production of all goods relative to another country, still it could have a comparative advantage in the production of one good if it is comparatively more efficient in the production of that good compared to the other good.

Again let us use Mexico and the U.S. in an example. We continue to assume that each country has 240 units of resources.

Before Trade:
           Mexico      U.S.         Mexico       U.S.       Wld
              Resources Needed                 Output
Rugs      10 hrs      8 hrs            12              15           27
 

Comtrs  40 hrs      10 hrs           3               12            15

The concept of Relative price:  Pr/Pc
In Mexico the relative price of one computer is 4 rugs; that is 40/10
In the U.S. the relative price of one computer is 1.25 rugs; that ia 10/8

After trade
                            Mexico   U.S.     Total
Rugs                    24             0           24
Computers           0              24          24

Gains: -3  R   ;       + 9 C
Note that to both countries 9 computers are valued a lot more than 3 (lost) rugs.

Study Questions- Test III

1. Explain the determinants of the demand for (real) money.
2. Why is it said that in the long run a one-time increase in the nominal money supply would not lead to a change in the interest rate?
3. Explain the equation of exchange.
4. Explain the concept of “purchasing power parity.”
5. Equilibrium in the money market at home and abroad is represented by:
                            M/P = L ,  M*/P* = L*
 respectively. Where:
   M, M* = Nominal money stock
   P, P*    =  The price level
   L, L*   =  Demand for real money

 a. Explain what the following equation implies.

  ^    ^            ^      ^           ^    ^
 (P – P*) =  ( M – M* ) – ( L – L*)        ( The symbol ^  represents % change.)

 b. Assuming that purchasing power parity holds explain the long-run impact of an expansionary monetary policy by the monetary authorities of foreign
countries on the exchange rate.

6. Outline some of the important reasons why PPP does not hold.
7. Why does there seem to be more empirical support for relative PPP than for absolute PPP?
8. Suppose the rate of growth in the US money stock is around 10 percent per annum whereas the European Central Bank has kept the growth rate of the
euro (money) stock at 6% per year. Assuming that the growth rates of demand for money in the United States and Europe are the same,
a. what does the monetary theory of foreign exchange predict to happen to the exchange rate between the US dollar and the euro in the long run?
b. Suppose the actual changes in the exchange rate indicate a 10% annual rate of depreciation in the US dollar (e^ = .10). What has been the percentage
change in the real exchange rate?

9. We know that an expansionary monetary policy could lead to the depreciation of the home currency in the short run. Would the impact of an accelerated
expansion in the money stock on the expected rate of change in the exchange rate in the long run be the same? Explain.
10. Suppose based on historical trends, the expected inflation rate in the United States is 5% while  in the U.K. it is around 8%. Explain how this inflation
differential could be linked to the interest differential between the two countries in the long run? Be specific about your assumptions.
11. Explain why it is said that if relative purchasing power parity between two countries holds, in the long run the real exchange rate will be expected to remain
unchanged.
12. Demonstrate that in the long run the difference between the expected real interest rates in two countries reflects the rate of change in the real exchange rate
between the countries’ currencies.
13. Explain why the aggregate demand curve is downward-sloping.
14. Identify the short-run, the long-run and the medium run aggregate supply curves and explain the assumptions under which each is constructed.
15. Under what conditions could and economy move beyond its full-employment level of output. Explain briefly.
16. What causes shifts in the medium-run aggregate supply curve? Explain.
17.  Is it possible for the long-run aggregate supply curve to shift? Explain.
18. What are the automatic forces that are expected to push the economy toward full employment in the long run? Explain.
19. Why is monetary policy expected to be ineffective as a macroeconomic policy tool under a fixed exchange rate regime?
20. Assume an economy is operating below its full-employment level of output. Using an aggregate demand and aggregate supply diagram, demonstrate how
under a fixed exchange rate regime with flexible prices fiscal policy can bring the economy to full employment. Compare the results of fiscal policy with the
results of the (possible) long-run automatic adjustments that could bring the economy to full employment.
21. Blueland is a small economy operating at its full-employment level of output. Suppose Blueland’s only trading partner, Redland, devaluates its currency
against the currency of Blueland. Using an aggregate demand and aggregate supply diagram, analyze the medium-run and long-run effects of this devaluation
(which is a revaluation of Bluland’s currency) on Blueland’s economy.  Assume perfectly mobile capital. Assuming that prior to the devaluation of its
currency Redland was also operating at full employment discuss the medium and long-run effects of this policy on Redland’s economy.
22. It is said that under a flexible exchange rate regime fiscal policy is not effective in changing the output level. Explain why.
23. Consider a small country with a flexible exchange rare regime. The country is at full employment. Still its monetary authorities pursue an expansionary
monetary policy. Using an aggregate supply and aggregate demand diagram demonstrate and explain how this policy might affect this economy in the medium
and long run.
24. What is meant by exchange rate overshooting?

23. Consider an open economy with a flexible exchange rate regime. Suppose due to an external disturbance the country is having a balance of payment deficit. Explain the mechanism through which the country’s external balance might be restored.
24. Consider an open economy with a fixed exchange rate regime. Suppose as a result of an external disturbance the country is experiencing a balance of payments deficit. Explain the process by which this country’s external balance would be restored.
25. What do we mean by external and internal balance?
26. Briefly explain the macroeconomic policy tools available to a country’s policy makers.
27. What is sterilization?
28. Explain why under a fixed exchange rate regime monetary policy is generally ineffective.
29. It is argued that when investors consider (domestic) bonds risky, under a fixed exchange rate regime, expansionary monetary policy could be at least partially effective. Explain why.
30. Consider an open economy with a fixed exchange rate regime and high level of capital mobility. The economy is presently at a general equilibrium, but it is suffering from unemployment. To deal with this problem the government resort to fiscal policy (deficit spending). Explain how fiscal policy might or might not remedy the unemployment problem in this country; what will be the effect of this policy on the country’s income level and interest rate? Be sure to use graphs in your analysis.
31. Explain how monetary policy in a reserve-currency country might affect non-reserve currency countries.
32. Consider an open economy with flexible exchange rates and perfectly mobile capital. To reduce the budget deficit the policy makers have reduced government spending by $500 million. The country’s spending multiplier has been estimated to be 2.4. Explain how this expenditure cut would affect the economy’s output, the domestic interest rate, and the exchange rate. First assume the expenditure cut is perceived to be temporary. Next, assume it is perceived to be permanent.
33. Consider an open economy with flexible exchange rates and perfectly mobile capital. The economy is operating below its full-employment level of output.

34. Consider an economy with a flexible exchange rate regime. The country is open to international trade but no capital flow is allowed. Suppose the country is experiencing unemployment. The country’s policy makers are considering their policy options for dealing with the unemployment problem. What would be your recommendation and why? Be as specific as you can in describing how your recommended policy might work and why you consider that preferable to other policy options available to the policy makers.
35. Consider an economy with a flexible foreign exchange market and highly (but not perfectly) mobile capital. The country is operating very close to the full-employment level of output. Fearing possible inflationary pressure, the country’s policy makers decide to undertake concretionary fiscal. They propose a $100 million tax increase in the country’s budget. Carefully explain how this tax increase could affect the country’s income, interest rate and foreign exchange rate. Evaluate the effectiveness of the policy first under the assumption that the tax increase is perceived as temporary. Next discuss the policy assuming that the tax increase is permanent.
36. Consider an economy with a flexible foreign exchange market and highly (but not perfectly) mobile capital. The economy is operating under the full-employment level of output. The country’s policy makers are evaluating the macroeconomic policy tools that could be used to eliminate or at least reduce the unemployment. While they want to make the economy grow to higher levels of output they want to keep the interest rate about the same (to minimize possible structural changes in the economy.) What kind of policy would you recommend and why? Carefully explain how your recommended policy would help this economy achieve both objectives.
 

Review questions for test 1:

After you have completed studying the relevant chapters in the book and your class notes, give yourself a quick test by going over the following questions. Do NOT limit yourself to only studying these questions.

1. Explain the important elements that distinguish economic relations between the residents of two different countries from the economic relations among the residents of the same country.

14. When a speculator expects a currency to depreciate more than what market indicates, should the speculator go long or short on that currency. Explain.
15. Consider an American investor who is not risk averse. This investor observes that the interest rate on a dollar-denominated time deposit is 5 percent whereas the interest rate on a similar euro-denominated deposit is 7 percent. Explain the conditions under which the speculator would still choose to keep her money in a dollar-denominated form of deposit.

Homework Assignment 3
March 24
1. The banking system in Southland, a small country, is made up of a Central Bank and a number of commercial banks whose operations are supervised by the Central Bank. The Central Bank’s assets (holdings) consist of only two types of assets: government bonds and foreign exchange. Commercial banks, whose only functions are accepting deposits and making loans, hold all their (cash) reserves with the Central Banks. Commercial banks are required to hold at least 20 percent of the value of their (checkable) deposits with the country’s Central Bank as “reserves.” Presently, there is $50 billion worth of the Central Bank’s notes in circulation and the commercial banks’ consolidated reserve deposits with the Central Bank also amount to $50 billion. Moreover, the Central Bank has $60 billion worth of government bonds. The commercial banks have collectively made $180 billion worth of loans and hold $200 billion checkable deposits for their customers.
Answer the following questions based on the information given above.
    a. What is the consolidated net worth of the commercial banks?
    b. Determine the country’s money stock.
    c. Are the commercial banks (collectively) meeting their reserve requirements? Explain.
    d. Can the commercial banks make any more loans without exceeding the limits of their     reserves? Explain.
    e. Can you determine the amount of foreign exchange the Central Bank is holding from the information given above?
    f. Now suppose the Central Bank has purchased $20 billion worth of foreign exchange. Assuming no change in the amounts of the notes in circulation, explain how this purchase would affect the Central Banks’ assets and liabilities. Also determine the potential effect of this FX purchase on the money stock of the country.

2. Determine the effect each of the following on the shape (slope) and the position of the IS and/or LM curve, ceteris paribus.
    a. An increase in the marginal propensity to consume
    b. An increase in the domestic price level
    c. Appreciation of the domestic currency
    d. A reduction in government spending
    e. An increase in the income level of the country’s trading partners
    f. Inflation in foreign countries
    g. Recession in foreign countries
    h. A reduction in the marginal propensity to import
    i. A reduction in the sensitivity of investment to changes in the interest rate
    j. An increase in the sensitivity of demand for money to changes in the interest rate



HOMEWORK ASSIGNMENT- Oct 9
1. Consider the following equation representing the equilibrium in the goods market:

Q =Y = E = C + I + G
where:
Y = income
E = expenditure
C = 500 + mpc (Y – T); mpc = 0.80 ; Ca = autonomous consumption; T = lump-sum tax = 300
I =  1500 - 20000 i
G = government expenditures = 400
i = interest rate = 0.05

a. Draw a diagram to demonstrate this equilibrium.
d. Determine the equilibrium income (Y).
c. Now suppose the interest rate is lowered to 0.04. How will this change affect the level of the economy’s output (Y)?
d. Show this change on your diagram.
e. See if you can derive this economy’s IS curve from your analysis.
f. Suppose the lowering of the interest rate is done by the Fed through an expansionary monetary policy (purchase of bonds). Explain how this policy affects economy’s money stock.
 

2. Explain the primary instruments that the Fed (or a central bank) could use to control the money supply.
 

3. Suppose the Fed sells $100 million worth of euro. Show the effect of this transaction on the Fed’s balance sheet and the consolidated balance sheet of commercial banks. Assuming that the required reserve ratio is 10 percent, how does this transaction affect the economy’s money stock?



Answer to HW 2 questions



Homework Assignment (Balance of Payments)

For each of the following show the entries in the US balance pf payments.

a. Boeing sells five passenger airplanes to China for a total price of $200 million. One half of this amount is paid out of the Chinese deposits in a US commercial bank in New York. Export-Import Bank of the United States finances the other half.
b. Microsoft Corporation pays its Indian subsidiary $100 million for software products produced in India. The payment is made by a check on one of Microsoft’s accounts with Bank of America.
c. Bill and Melinda Gates Foundation gives $500 million to a number of African countries for fight against AIDS. This money goes directly to a number of American pharmaceutical companies and American aid agencies that provide health care in developing countries.
d. With government approval, Boeing sells four advanced fighter jets to Saudi Arabia for a total price of $200 million. The Saudis pay $100 million in cash out of their bank account in a British bank. (This transaction reduces the British bank’s deposits in the US.) The balance of the invoice is financed by Export-Import Bank of the United States.
e. A major New York’s spirit merchant buys $15 million worth of vodka from Russia. $5 million of this amount is paid cash by a direct transfer into the Russian exporter’s bank account in an American bank. The American importer has agreed to pay the balance in two equal installments within 9 months.
f. Determine the net effect of the above transactions on each of the following balances:
    i·   The current account balance
    ii·  The non-official capital balance
    iii· The official settlement balance

2. Consider a country with a GNP, Y, of $100 billion. Suppose presently the country is having a currant account balance of $8 billion.
a. Assuming the economy is at equilibrium, demonstrate the country’s national income, Y, and current account balance in a set of diagrams.
b. Now suppose the economy’s marginal propensity to consume is .85 while its marginal propensity to import is .10. Assuming no change in the country’s interest rare, exchange rate, price level, taxes, and its trading partners’ incomes and prices, determine the impact of a $10 billion increase in government spending (deficit spending) on the country’s current account.
c. Now suppose while increasing the government expenditure (as explained above), to correct its current account balance, the government devaluates the country’s currency by 20 percent. The initial effect of this devaluation is an (exogenous) increase in the country’s exports in the amount of $12 billion. The devaluation has also a direct immediate (exogenous) effect on imports; it reduces impotrs by $4 billion. Taking into account the secondary (endogenous) effects of the increased exports and imports determine the total effect of deficit spending and devaluation on the country's current account balance.

A Supplementary Final Assignment
Due: Thursday, May 10, 2001
*********************
1.  Rockland is a small island nation that imports most of its needs, whereas its major source of external revenue is its export of oil. The country’s currency is “ rial”.  Rockland’s demand schedule for imported goods is a follows:
Price (Rials)         Quantity
100                        7500
120                        7000
140                         6500
160                         6000
180                         5500
200                         5000

a. Assuming that the dollar unit price of Rockland’s imports is $10 --i.e., changes in the rial price of imports are the result of changes in the exchange rate— draw up the demand schedule of Rockland for dollars.

b. Presently the price of oil in the international market is $20 per barrel and as a small supplier of oil, Rockland sells its entire output of crude on the open market. Its production capacity is about 3000 barrel a day, and Rockland generally produces to the capacity. Draw the country’s supply of dollar.

c. Presently Rockland’s central bank has fixed the exchange rate at 14 rials per dollar. What is the status of the current account balance of Rockland at this exchange rate?

d. If Rockland's central bank lets its currency float, will it depreciate or appreciate?

e. Now suppose Rockland enters into a bilateral agreement with a neighboring country, Agriland, to sell all of its oil to that country. In return, Rockland agrees to buy most of its imports from that country as long as their prices are in line with international prices. Rockland however does not have the option of selling its oil to other countries. It has agreed to sell all of its oil to Agriland, provided that it can charge whatever price it wants according to that country's market. Agriand's currency is dollar and its demand for oil is as follows:

$P            Quantity (barrels)
24                2460
23                2480
22                2500
21                2520
20                2540
19               2560

At the exchange rate of 14 rials per dollar, to take advantage of its monoply power Rockland charges Agriland's residents 308 rials per barrel for its oil.  Determine the status of Rockland's current account (in rials)?

f. Assuming a fixed rial price for oil (308 rials), plot Rockland's supply of dollars.

g. In order to improve its current account should Rockland's central bank devaluate or revaluate (raise the value of) the country's currency (the rial)?

2. You are given the following national expenditure and income functions:
 

Y = C + I + G + X - M
Y = C + S + T

 where  C = 200 + .75  Yd
             Yd = Y - T
I = 40
G = 80
T = 60
X = 60
M = 20 + .15Y   (Note here that import is directly linked to income (Y) not disposable income, Yd)

a. Determine the equilibrium level of output for this economy.
b. What is the country's balance of trade?
c. Using an injection-leakage graph, show the country's balance of trade.
d. If you were to improve the country's balance of trade through fiscal policy, would you increase taxes, reduce taxes, increase government expenditures, or reduce government expenditures? Explain.

Spot arbitrage practice:

Determine if there is a spot arbitrage oppotunity amoung each of the follwing two sets of spot rates. Next, show how an investor can take advatage of it, if there is one. Assume that the dollar is your home currency.

a.  $/Pound   =    $1.65
     $/DM      =    $.554
     DM/Pound  =  DM 3
Answer:
1.To determine whether or not there an arbitrage opportunity cross two of the rates and compare the cross rate with the third rate. In this case let us cross $/DM and DM/Pound. That will give us cross $/Pound:  3 x .554  =  $1.662/Pound

2. The cross rate $1.662 is greater than the third rate. That tells us that there is an arbitrage oppotunity.

3. We will do our calculation for one dollar. Convert your dollar to pound: 1/1.65 = .6060 pound.

4. Convert the pound to DM:  .6060 x 3 =  1.8181 DM

5. Convert the DM to dollar:  1.8181 x .554 =  1.0072

This mean that you have made $.0072 on each dollar that you engaged in this arbritrage transaction.
If you engaged $1,000,000., you would make $7,200 on the spot.
====================
b. Yen/DM = 65 DM
     $/DM    =  $.554
     Yen/$    =   120 Yen
Answer:
1.To determine whether or not there an arbitrage opportunity cross two of the rates and compare the cross rate with the third rate. In this case let us cross $/DM and Yen/$. That will give us cross Yen/DM: 120 x .554  =  66.48 Yen

2. The cross rate 66.48 Yen is greater than the third rate, 65 Yen/DM. That tells us that there is an arbitrage oppotunity.

3. We will do our calculation for one dollar. Convert your dollar to Yen: 1 X 120 = 120 Yen.

4. Convert the Yen to DM:  120/65  =  1.84615 DM

5. Convert the DM to dollar:  1.84615  x .554 =  1.022

This mean that you have made $.022 on each dollar that you engaged in this arbritrage transaction.
If you engaged $1,000,000., you would make $22,000 on the spot.

Problem Sets on Exchange Rate Determination

1.Assume the six-month forward exchange rate on the Canadian dollar is $.65. The spot rate on this currency is $.63.

a) Assuming that the (annual) interest rate in Canada is 10 percent and in the U.S. it is 9 percent, is there interest parity between these two countries? Explain. If interest parity does not exist, what will happen?

b) Assuming that the (annual) interest rate in the U.S. is 12 percent, what should be the Canadian interest rate for interest parity to prevail?

c) Now assume that the spot rate for the Canadian dollar is $.63. If the (annual) interest rate in the U.S. is 10 percent and in Canada it is 13 percent, what should be the six-month forward rate for the Canadian dollar for interest parity to prevail?

2. The 90-day forward rate for the Canadian dollar is .$67 (or C$1.4925 per US$) which puts it at a discount of 4 percent against the US dollar.

a. Determine the spot rate for the Canadian dollar.

b. Now assume that the interest rate on 90-day certificates of deposit in Canada is 11 per cent whereas in the US the interest rate on similar certificates is 5 percent. Suppose you could borrow up to $5,000,000 for 90 days at 6 percent in the US. Also assume you could borrow the same amount in Canada for the same period at 12 percent. Do you see any interest arbitrage opportunity here? If yes, how would you take advantage of it without any risk? Clearly demonstrate.
