International trade is the trade between two or more countries.
The essence of international trade is specialization.
That is, a country should specialize in the production of those things for which it has the greatest advantage over others.
Such specialization results in a greater volume of output for the world than would be possible if each country tried to produce everything it needed.
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 be available to us.
It is the reason you can pick between a Japanese, German or 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.
As it opens the opportunity for specialization and therefore more efficient use of resources international trade has the potential to maximize a country’s capacity to produce and acquire goods.
Opponents of global trade have argued, however, that international trade 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.
