## What you’ll learn to do: describe how nations measure global trade

In the same way that nations measure their own economic productivity, they use specific tools to measure their trade with other nations. In this section you’ll learn what some of those tools are and how they’re used.

### Learning Objectives

• Differentiate between balance of trade and balance of payments

## Balance of Trade and Balance of Payments

In this section we’ll look at two key measurements of trade: balance of trade and balance of payments.

One of the ways that a country measures global trade is by calculating its balance of trade. Balance of trade is the difference between the value of a country’s imports and its exports, as follows:

value of exports – value of imports = balance of trade

NOTE: It’s important to use this formula just as it’s presented, without altering the sequence of values.

### Imagine Nation’s Balance of Trade

Let’s look at the balance of trade for “Imagine Nation.”

Imagine Nation is located in a region that lacks phosphate as a natural resource. However, it does have an abundance of sugarcane. As a result of its comparative advantages, Imagine Nation imports phosphate from Christmas Island (it’s a real place in Australia—look it up!) to fertilize the sugarcane it grows, and it uses the sugarcane to manufacture saltwater taffy, which it exports to Christmas Island. The following table shows Imagine Nation’s imports and exports with Christmas Island in 2017.

 Imports (phosphate) Exports (taffy) 2017 $45,000,000$75,000,000

Using these figures, we can easily calculate Imagine Nation’s balance of trade in 2014:

$75,000,000 (exports) −$45,000,000 (imports) = $30,000,000 This means that Imagine Nation had a trade surplus of$30,000,00 with Christmas Island, since exports exceeded imports. We can also say that Imagine Nation was a “net exporter,” meaning they exported more than they imported.

However, the picture changed in 2018 when the Australian government closed the phosphate mine on Christmas Island. Imagine Nation had to import phosphate from Morocco, instead, and was not able to get the same favorable pricing as before. Consequently, sugarcane farmers paid more for fertilizer, the price of sugarcane went up, and Imagine Nation had to raise the price on its saltwater taffy. Sadly, the people of Morocco aren’t really big fans of saltwater taffy, so exports fell. The following table shows Imagine Nation’s imports and exports with Morocco in 2018.

 Imports (phosphates) Exports (taffy) 2018 $65,000,000$55,000,000

We can use the figures to calculate Imagine Nation’s balance of trade:

$55,000,000 (exports) −$65,000,000 (imports) = −$10,000,000 The negative number indicates a trade deficit of$10,000, showing that Imagine Nation’s imported more from Morocco than it exported. We would say that Imagine Nation became a “net importer”—importing more than it was exporting.

Obviously this is a simple example. A country’s global business doesn’t amount to just trading phosphate and taffy or cell phones and blue jeans. It includes all kinds of financial transactions: goods and services imported and exported, foreign investments, loans, transfers, and so on. Tracking all these payments provides another way to measure the size of a country’s international trade: the balance of payments.

### Balance of Payments

Balance of Payments is the difference between the total flow of money coming into a country and the total flow of money going out of a country during a period of time. Although related to the balance of trade, balance of payments is the record of all economic transactions between individuals, firms, and the government and the rest of the world in a particular period. Thus the balance of payments includes all external transactions of a country, including payments for the country’s exports and imports of goods, services, foreign investments, loans and foreign aid, financial capital, and financial transfers.

• For instance, if a US company buys land or a factory in another country, that investment is included in the US balance of payments as an outflow. Likewise, if a US company is sold to a foreign company, it’s included in the balance of payments. Just recently, Didi Chuxing, the Chinese ride-hailing service, bought Uber’s subsidiary in China in a deal valued at $35 billion. This sale will create a cash inflow to the United States, but over the long term it will decrease the revenue flowing in from China through Uber. • If a nation receives foreign aid or borrows money from another country, this amount is also reflected in its balance of payments as a cash inflow. For example, the bailout Greece received from the Eurozone and IMF in 2010 to help stabilize its failing economy affected the balance of payments for all of the nations involved. Greece recorded the €110 billion loan as an inflow in its balance of payments, while the Eurozone members recorded it as an outflow in their balance of payments. A country’s balance of payments is calculated as follows: total money coming into a country (inflow)− total money going out (outflow) = balance of payments NOTE: It’s important to use this formula just as it’s presented, without altering the sequence of values. ### Imagine Nation’s Balance of Payments Let’s examine Imagine Nation’s balance of payments in 2018. The following table shows all of its external transactions during the year.  Imports (phosphates) Exports (taffy) Foreign aid (loan) from Hooperland Purchase of Wandaland assets 2018$65,000,000 $55,000,000$25,000,000 $30,000,000 When we calculated Imagine Nation’s balance of trade in 2018, we did not take into account the following two transactions: 1. Imagine Nation received foreign aid in the form of a loan from the government of Hooperland in the amount of$25,000,000. This inflow of funds will affect Imagine Nation’s balance of payments.
2. Imagine Nation invested in a factory in Wandaland and purchased the factory from the government for $30,000,000. This outflow of funds will affect Imagine Nation’s balance of payments. When we calculate Imagine Nation’s 2018 balance of payments, by taking the inflows (revenue from exports and foreign aid) and subtracting the outflows (payments for imports and purchase of foreign assets), the balance is negative, as shown below: ($55,000,000 + $25,000,000) (total inflow) – ($65,000,000 + $30,000,000) (total outflow) = −$15,000,000

What effect will this have on Imagine Nation? Well, when Imagine Nation’s leader is briefed by her council of international economic advisers, they will inform her that the country currently has an “unfavorable balance of payments.” That is, less money is coming into the country than is going out. If, on the other hand, the balance of payments were a positive number (inflow exceeded outflow), Imagine Nation could say that it has a “favorable balance of payments.”

At this point it’s tempting to make judgments about these different types of trade measurements and conclude that trade surpluses and favorable balance of payments are always indicators of a strong economy, but unfortunately it’s not so cut and dried. Balance of trade and balance of payments are starting points—much in the way that an individual’s credit rating might be a starting point for seeking a loan. How the numbers are interpreted and viewed by the country’s leaders, other countries, and the world depends on many factors, such as where a country is in its economic development, the factors contributing to the balance of trade or payments, the health of the overall global economy, what the country is doing with its imports, and so on. As you might guess, assessments of these factors can be intensely political. You’ll learn more about these considerations later in this module when we discuss how nations attempt to restrict or control trade.

### Practice Questions

So far we have discussed global trade measured in dollars, euros, or other traditional currency, which is the way that everyone assumes business is conducted today. For example, here in the United States, we express the size of the global market, or Global World Product (GWP), as U.S. \$107.5 trillion. If we lived in Japan, we’d measure GWP using Japanese currency, yen (¥).

However, when we measure global trade only in terms of currency-based transactions, we omit a portion of the market known as countertrade. Countertrade is a system of exchange in which goods and services are used as payment rather than money. There are many types of countertrading. Some of the most common types are described below:

1. Barter: Exchange of goods or services directly for other goods or services without the use of money as means of purchase or payment. Example: One party trades salt for sugar from another party.
2. Switch trading: Practice in which one company sells to another its obligation to make a purchase in a given country. Example: Party A and Party B are countertrading salt for sugar. Party A may switch its obligation to pay Party B to a third party, known as the switch trader. The switch trader gets the sugar from Party B at a discount and sells it for money. The money is used as Party A’s payment to Party B.
3. Counterpurchase: Sale of goods and services to one company in another country by a company that promises to make a future purchase of a specific product from the same company in that country. Party A sells salt to Party B. Party A promises to make a future purchase of sugar from Party B.
4. Buyback: This occurs when a firm builds a plant in a country, or supplies technology, equipment, training, or other services to the country, and agrees to take a certain percentage of the plant’s output as partial payment for the contract. Example: Party A builds a salt-processing plant in Country B, providing capital to this developing nation. In return, Country B pays Party A with salt from the plant.
5. Offset: Agreement that a company will offset a hard-currency purchase of an unspecified product from that nation in the future. Agreement by one nation to buy a product from another, subject to the purchase of some or all of the components and raw materials from the buyer of the finished product, or the assembly of such product in the buyer nation. Example: Party A and Country B enter a contract where Party A agrees to buy sugar from Country B to manufacture candy. Country B then buys that candy.

### PRactice Question

Countertrading is common among countries that lack sufficient hard currency (i.e., cash) or where other types of market trade are impossible. In developing countries, whose currency may be weak or devalued relative to another country’s currency, bartering may be the only way to trade. For example, if the value of Venezuela’s currency, the bolívar fuerte, falls relative to the U.S. dollar (as it has in recent years), the exchange rate makes it unfavorable for Venezuela to sell its oil to the United States. Countertrade may be a much more financially beneficial arrangement.
