What is Trade?

Trade is the voluntary exchange between economic actors of different goods and services. A transaction can only be made if both the parties feel it is in their best interests.


In different contexts, trade can take on additional meanings. Trade is the sale and purchase of securities, commodities or derivatives. International trade is free from tariffs and other trade obstacles.



  • The voluntary exchange of goods and services between economic actors is called trade.
  • Because transactions are consensual they can be viewed as a benefit to both sides.
  • Trading is a financial term that refers to the sale or purchase of securities or assets.
  • The theory of comparative advantage in international trade predicts that trade will be beneficial for all.
  • While most classical economists favor free trade, some development economists see the benefits of protectingionism.




How trade works

Trade can be used to refer to any voluntary exchange. It could include the exchanging of baseball cards between collectors or multimillion-dollar contracts among companies.

In macroeconomics trade is usually used to refer to international commerce, which is the system of imports and exports that connects global economies. An export product is one that is sold to the international market. A product that is purchased from the global marketplace is an import. For well-connected countries, exports can be a significant source of wealth.


International trade results in greater efficiency and allows countries to take advantage of foreign direct investments (FDI). Foreign direct investment (FDI) can help increase the country’s employment and skills by bringing in foreign currency and expertise. FDI can provide opportunities for growth and expansion of a company, which eventually leads to higher revenues.


A trade deficit refers to a situation in which a country pays more for aggregate imports from overseas than it makes from aggregate exports. A trade deficit is an outflow of domestic currency into foreign markets. Also known as a negative balance (BOT), this could be described as a trade deficit.


Trade benefits

Different countries have different natural resources and assets. This means that some countries might be able to produce the same product more efficiently and sell it cheaper than others. Trade can help countries take advantage of lower prices in other countries.


This principle is commonly known as the law of comparative advantage. It was popularly attributed to David Ricardo and the Principles of Political Economy and Taxationin1817. It is possible that Ricardo’s mentor James Mill invented the analysis.

According to the United Nations, the total global trading market’s value is 1.

Ricardo demonstrated how England and Portugal benefit from specializing and trading according their respective advantages. Portugal was able make wine at a lower cost than England, and England could produce cloth cheaply. Both countries could trade more goods if they focused on their relative advantages.


The theory of comparative advantages helps explain why protectionionism can often be counterproductive. Although a country may use tariffs or other trade barriers to benefit specific industries or interests groups, they also block their consumers from accessing cheaper goods from overseas. This would eventually lead to a country being economically less competitive than countries that trade.


Criticisms of trade

Although the law of comparative advantages is a common feature of introductory economics many countries still try to protect local industries by imposing tariffs, subsidies or other trade barriers. . Economists refer to rent-seeking as one possible explanation. Rent-seeking is when one group organizes itself and lobby the government to protect their interests.


Business owners may try to pressure their country’s government to impose tariffs on cheap foreign goods. This could lead them to sacrificing the livelihoods and security of their workers. Even though business owners may understand the advantages of trade, it is possible for them to be reluctant about giving up a lucrative stream of income.


There are strategic reasons countries should avoid over dependence on free trade. A country that depends on trade could be dependent on the global marketplace for key goods.


Some economists advocate tariffs to protect the growth of infant industries that are not yet able to compete on the global marketplace. These industries will move up the learning curve and are likely to attain a comparative advantage.


What does the WTO do to promote global free trade?

The World Trade Organization is an intergovernmental organization that oversees and enforces trade deals between different countries. It’s primary purpose is to mediate and adjudicate trade disputes between countries that are accused of unfair trade practices. The WTO may be called upon to resolve a dispute if a country’s laws make selling foreign products difficult in that country.


Are Trade and Jobs Good?

International trade is not all about winners and losers. Some industries will benefit from the global price differential while others will be struggling to compete. Trade is expected to have a net positive effect on employment, as it allows consumers and businesses to get the best prices, and the savings can be used to support other economic activities.
