International trade is the exchange of goods and services between countries. It 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.
International trade can benefit us a lot. Trading globally allows us to expand our markets for both goods and services that otherwise may not have been available to us. If you walk into a supermarket and are able to buy Indonesian bananas, Brazilian coffee and a bottle of French wine, you are experiencing the effects of international trade.
International trade brings us both advantages and disadvantages. For instance, international trade may also make the world economy easily affected by factors like prices, supply and demand, as well as global events. Political change in Asia, for example, could result in an increase in the cost of labor, thereby increasing the manufacturing costs for an American sneaker company based in Malaysia, which would then result in an increase in the price that you have to pay to buy the tennis shoes at your local mall. A decrease in the cost of labor, on the other hand, would result in you having to pay less for your new shoes.
