The Balance of Payments: Linking the United States to the International Economy

• Current account records a country’s net exports, net income on investments, and net transfers... That is, payments for currently produced goods and services including labor services (paid wages) and capital services (paid “investment income”)

• Balance of merchandise trade (sometimes called “balance of trade”)

• Balance of trade in goods and service

Balance of payments The record of a country’s trade with other countries in goods, services, and assets.

• Financial account records a country’s sales of domestic asset to foreign residents and purchase of foreign assets by domestic residents.

• Net foreign investment The difference between capital outflows from a country and capital inflows, also equal to net foreign direct investment plus net foreign portfolio investment.

Balance of payments 0

So how do we pay for the excess of current account payments to foreigners over what they pay to US?

We sell them our IOUs and other assets (stocks, bonds, real estate deeds) Net foreign investment The difference between capital outflows from a country and capital inflows, also equal to net foreign direct investment, FDI, (in “factories”) plus net foreign portfolio investment (stocks and bonds).• The “Balance of Payments” (BoP)is always zero (statistical

discrepancy makes it so)

• Sometimes BoP refers to net private transactions in goods, services, and assets (China’s “BoP” surplus Bank of China buys US bonds)

Exchange Rates in the Financial Pages

That was then…this is now

The Foreign Exchange Market and Exchange Rates

1 Foreign firms and households who want to buy goods and services produced in the United States.

2 Foreign firms and households who want to invest in the United States either through foreign direct investment — buying or building factories or other facilities in the United States — or through foreign portfolio investment — buying stocks and bonds issued in the United States.

3 People doing international business transacted in dollars.

3 Currency traders who believe the value of the dollar will increase.

Sources of demand for the U.S. dollar:

Sources of supply of the U.S. dollar are analogous: US residents who want to buy foreign stuff or paper or hold foreign currencies

Equilibrium in the Market for Foreign Exchange

Currency appreciation An increase in the market value of one currency relative to another currency.

Currency depreciation A decrease in the market value of one currency relative to another currency.

How Do Shifts in Demand and Supply Affect the Exchange Rate?

1 Changes in the demand for U.S.-produced goods and services and changes in the demand for foreign-produced goods and services

2 Changes in the desire to invest in the United States and changes in the desire to invest in foreign countries

3 Changes in the expectations of currency traders about the likely future value of the dollar and the likely future value of foreign currencies

Factors that cause the demand and supply curves in the foreign exchange market to shift:

Shifts in the Demand and Supply Curve Resulting in a Higher Exchange Rate

Some Exchange Rates Are Not Determined by the Market

Some currencies have fixed exchange rates that do not change … until they

are forced to: a payments deficit drains Central Bank foreign exchange

holdings; Ms declines; i rises capital inflows; Y and P fall Im decline

Balance of Payments balances at the fixed exchange rate.

• For economy below potential GDP, real depreciation/devaluation of the currency should increase net exports, aggregate demand, and real GDP.

• Real appreciation/revaluation of the domestic currency should have the opposite effect .

How Movements in the Exchange Rate Affect Exports and Imports

The Foreign Exchange Market and Exchange Rates

Real exchange rate The price of domestic goods in terms of foreign goods.

Domestic price levelReal exchange rate = Nominal exchange rate ×Foreign price level

Some international monetary arithmeticCurrent Account Balance + Financial Account Balance = 0or:Current Account Balance = -Financial Account Balanceor:Net Exports = Net Foreign Investment … NX = NFI

Private Saving = National Income – Consumption - TaxesSprivate = Y – C – T = (C + I + G + NX) - C - T = [I + (G - T) + NX]

• Private saving finances domestic and foreign investment and a government deficit

Public Saving = Taxes – Gov’t Spending = Spublic = T – G National Saving = Private Saving + Public Saving

S = Sprivate + Spublic

S = [I + (G - T) + NX] + (T - G) = I + NFICapital In = - NFI= I - S=I - Sprivate - (T-G)= (I - Sprivate) + (G - T)
