If you walk into a supermarket and are able to buy South American bananas, Brazilian coffee
and a bottle of South African wine, you are experiencing the effects of international trade.
International trade allows us to expand our markets for both goods and services that otherwise
may not have been available to us. It is the reason why you can pick between a Japanese,
German and American car. As a result of international trade, the market contains greater
competition and therefore more competitive prices, which bring a cheaper product home to the
consumer.
Trading globally gives consumers and countries the opportunity to be exposed to goods and
services not available in their own countries. Almost every kind of product can be found on the
international market: food, clothes, spare parts, oil, jewelry, wine, stocks, currencies and water.
Services are also traded: tourism, banking, consulting and transportation. A product that is sold
to the global market is an export, and a product that is bought from the global market is an
import. Imports and exports are accounted for in a country's current account in the balance of
payments. (For more on this, see the articles What Is The Balance Of Payments? and
Understanding The Current Account In The Balance Of Payments.)
Let's take a simple example. Country A and Country B both produce cotton sweaters and wine.
Country A produces 10 sweaters and six bottles of wine a year while Country B produces six
sweaters and 10 bottles of wine a year. Both can produce a total of 16 units. Country A, however,
takes three hours to produce the 10 sweaters and two hours to produce the six bottles of wine
(total of five hours). Country B, on the other hand, takes one hour to produce 10 sweaters and
three hours to produce six bottles of wine (total of four hours).
But these two countries realize that they could produce more by focusing on those products with
which they have a comparative advantage. Country A then begins to produce only wine and
Country B produces only cotton sweaters. Each country can now create a specialized output of
20 units per year and trade equal proportions of both products. As such, each country now has
access to 20 units of both products.
We can see then that for both countries, the opportunity cost of producing both products is
greater than the cost of specializing. More specifically, for each country, the opportunity cost of
producing 16 units of both sweaters and wine is 20 units of both products (after trading).
Specialization reduces their opportunity cost and therefore maximizes their efficiency in
acquiring the goods they need. With the greater supply, the price of each product would
decrease, thus giving an advantage to the end consumer as well.
Note that, in the example above, Country B could produce both wine and cotton more efficiently
than Country A (less time). This is called an absolute advantage, and Country B may have it
because of a higher level of technology. However, according to international trade theory, even if
a country has an absolute advantage over another, it can still benefit from specialization. (For a
review of some of these economic concepts, see the Economics Basics tutorial.)
For the receiving government, FDI is a means by which foreign currency and expertise can enter
the country. These raise employment levels and, theoretically, lead to a growth in the gross
domestic product. For the investor, FDI offers company expansion and growth, which means
higher revenues.
Conclusion
As it opens up the opportunity for specialization and therefore more efficient use of resources,
international trade has potential to maximize a country's capacity to produce and acquire goods.
Opponents of global free trade have argued, however, that international trade still allows for
inefficiencies that leave developing nations compromised. What is certain is that the global
economy is in a state of continual change and, as it develops, so too must all of its participants
