Principles of Macroeconomics for AP® Courses9.1 Measuring Trade Balances

### Learning Objectives

By the end of this section, you will be able to:

• Explain merchandise trade balance, current account balance, and unilateral transfers
• Identify components of the U.S. current account balance
• Calculate the merchandise trade balance and current account balance using import and export data for a country

### Components of the U.S. Current Account Balance

Table 9.1 breaks down the four main components of the U.S. current account balance for the last quarter of 2014 (seasonally adjusted). The first line shows the merchandise trade balance; that is, exports and imports of goods. Because imports exceed exports, the trade balance in the final column is negative, showing a merchandise trade deficit. How this trade information is collected is explained in the following Clear It Up feature.

Value of Exports (money flowing into the United States) Value of Imports (money flowing out of the United States) Balance
Goods $410.0$595.5 –$185.3 Services$180.4 $122.3$58.1
Income receipts and payments $203.0$152.4 $50.6 Unilateral transfers$27.3 $64.4 –$37.1
Current account balance $820.7$934.4 –$113.7 Table 9.1 Components of the U.S. Current Account Balance for 2014 (in billions) ### Clear It Up #### How does the U.S. government collect trade statistics? Do not confuse the balance of trade (which tracks imports and exports), with the current account balance, which includes not just exports and imports, but also income from investment and transfers. Statistics on the balance of trade are compiled by the Bureau of Economic Analysis (BEA) within the U.S. Department of Commerce, using a variety of different sources. Importers and exporters of merchandise must file monthly documents with the Census Bureau, which provides the basic data for tracking trade. To measure international trade in services—which can happen over a telephone line or computer network without any physical goods being shipped—the BEA carries out a set of surveys. Another set of BEA surveys track investment flows, and there are even specific surveys to collect travel information from U.S. residents visiting Canada and Mexico. For measuring unilateral transfers, the BEA has access to official U.S. government spending on aid, and then also carries out a survey of charitable organizations that make foreign donations. This information on international flows of goods and capital is then cross-checked against other available data. For example, the Census Bureau also collects data from the shipping industry, which can be used to check the data on trade in goods. All companies involved in international flows of capital—including banks and companies making financial investments like stocks—must file reports, which are ultimately compiled by the U.S. Department of the Treasury. Information on foreign trade can also be cross-checked by looking at data collected by other countries on their foreign trade with the United States, and also at the data collected by various international organizations. Take these data sources, stir carefully, and you have the U.S. balance of trade statistics. Much of the statistics cited in this chapter come from these sources. The second row of Table 9.1 provides data on trade in services. Here, the U.S. economy is running a surplus. Although the level of trade in services is still relatively small compared to trade in goods, the importance of services has expanded substantially over the last few decades. For example, U.S. exports of services were equal to about one-half of U.S. exports of goods in 2014, compared to one-fifth in 1980. The third component of the current account balance, labeled “income payments,” refers to money received by U.S. financial investors on their foreign investments (money flowing into the United States) and payments to foreign investors who had invested their funds here (money flowing out of the United States). The reason for including this money on foreign investment in the overall measure of trade, along with goods and services, is that, from an economic perspective, income is just as much an economic transaction as shipments of cars or wheat or oil: it is just trade that is happening in the financial capital market. The final category of the current account balance is unilateral transfers, which are payments made by government, private charities, or individuals in which money is sent abroad without any direct good or service being received. Economic or military assistance from the U.S. government to other countries fits into this category, as does spending abroad by charities to address poverty or social inequalities. When an individual in the United States sends money overseas, it is also counted in this category. The current account balance treats these unilateral payments like imports, because they also involve a stream of payments leaving the country. For the U.S. economy, unilateral transfers are almost always negative. This pattern, however, does not always hold. In 1991, for example, when the United States led an international coalition against Saddam Hussein’s Iraq in the Gulf War, many other nations agreed that they would make payments to the United States to offset the U.S. war expenses. These payments were large enough that, in 1991, the overall U.S. balance on unilateral transfers was a positive$10 billion.

The following Work It Out feature steps you through the process of using the values for goods, services, and income payments to calculate the merchandise balance and the current account balance.

Table 9.2 Calculating Merchandise Balance and Current Account Balance

Use the information given below to fill in Table 9.2, and then calculate:

• The merchandise balance
• The current account balance

Known information:

• Unilateral transfers: $130 • Exports in goods:$1,046
• Exports in services: $509 • Imports in goods:$1,562
• Imports in services: $371 • Income received by U.S. investors on foreign stocks and bonds:$561
• Income received by foreign investors on U.S. assets: $472 Step 1. Focus on goods and services first. Enter the dollar amount of exports of both goods and services under the Export column. Step 2. Enter imports of goods and services under the Import column. Step 3. Under the Export column and in the row for Income payments, enter the financial flows of money coming back to the United States. U.S. investors are earning this income from abroad. Step 4. Under the Import column and in the row for Income payments, enter the financial flows of money going out of the United States to foreign investors. Foreign investors are earning this money on U.S. assets, like stocks. Step 5. Unilateral transfers are money flowing out of the United States in the form of military aid, foreign aid, global charities, and so on. Because the money leaves the country, it is entered under Imports and in the final column as well, as a negative. Step 6. Calculate the trade balance by subtracting imports from exports in both goods and services. Enter this in the final Balance column. This can be positive or negative. Step 7. Subtract the income payments flowing out of the country (under Imports) from the money coming back to the United States (under Exports) and enter this amount under the Balance column. Step 8. Enter unilateral transfers as a negative amount under the Balance column. Step 9. The merchandise trade balance is the difference between exports of goods and imports of goods—the first number under Balance. Step 10. Now sum up your columns for Exports, Imports, and Balance. The final balance number is the current account balance. The merchandise balance of trade is the difference between exports and imports. In this case, it is the difference between$1,046 – $1,562, a trade deficit of –$516 billion. The current account balance is –$419 billion. See the completed Table 9.3. Exports Imports Balance Goods$1,046 $1,562 –$516
Services $509$371 $138 Income payments$561 $472$89
Unilateral transfers - $130 –$130
Current account balance $2,116$2,535 –\$419
