Chapter 1

Keeping Up With a Changing World-Trade Flows, Capital Flows, and the Balance Of Payments

1. The balance on merchandise trade is the difference between exports of goods, 719 and the imports of goods,

1,145, for a deficit of 426. The balance on goods, services and income is 719 + 279 +284 – 1145 - 210 –269, for a deficit of 342. Adding unilateral transfers to this gives a current account deficit of 391, [-342 + (-49) = -391]. (Note that income receipts are credits and income payments are debits.)

2. Because the current account balance is a deficit of 391, then without a statistical discrepancy, the capital

account is a surplus of 391. In this problem, however, the statistical discrepancy is recorded as a positive amount (credit) of 11. Hence, the sum of the debits in the balance of payments must exceed the credits by

11. So, the deficit of the current account must be greater than the surplus on the capital account by 11.

The capital account, therefore, is a surplus of 391 – 11 = 380.

3. A balance-of-payments equilibrium is when the debits and credits in the current account and the private

capital account sum to zero. In the problem above we do not know the private capital account balance.

We cannot say, therefore, whether this country is experiencing a balance-of-payments surplus or deficit or if it is in equilibrium.

4 The current account is a deficit of $541,830 and the private capital account balance is a surplus of $369,068.

The U.S., therefore, has a balance of payments deficit.

5 Positive aspects of being a net debtor include the possibility of financing domestic investment that is not

possible through domestic savings; thereby allowing for domestic capital stock growth which may allow job, productivity, and income growth. Negative aspects include the fact that foreign savings may be used to finance domestic consumption rather than domestic savings; which will compromise the growth suggested above.

Positive aspects of being a net creditor include the ownership of foreign assets which can represent an

income flows to the crediting country. Further, the net creditor position also implies a net exporting

position. A negative aspect of being a net creditor includes the fact that foreign investment may substitute for domestic investment.

6 A nation may desire to receive both portfolio and direct investment due to the type of investment each

represents. Portfolio investment is a financial investment while direct investment is dominated by the

purchase of actual, real, productive assets. To the extent that a country can benefit by each type of

investment, it will desire both types of investment. Further, portfolio investment tends to be short-run in nature, while FDI tends to be long-run in nature. This is also addressed in much greater detail in Chapter 7.

7. Domestic Savings - Domestic Investment = Current Account Balance

Domestic Savings - Domestic Investment = Net Capital Flows

Therefore, Current Account Balance = Net Capital Flows

8 Using the equations above, private savings of 5 percent of income, government savings of -1 percent, and

investment expenditures of 10 percent would results in a current account deficit of 6 percent of income and a capital account surplus (net capital inflows) of 6 percent of income. This could be corrected with a

reduction in the government deficit (to a surplus) and/or an increase in private savings.

The Market for Foreign Exchange

1. Because it costs fewer dollars to purchase a euro after the exchange rate change, the euro depreciated relative

to the dollar. The rate of depreciation (in absolute value) was [(1.2168 – 1.2201)/1.2201]100 = 0.27 percent.
