Advantages and Disadvantages of International Trade
Advantages
Increase in Revenue: International trade boosts revenue and business growth by increasing the number of potential clients and opening opportunities for expansion into new markets.
Better Availability of Goods and Services: International trade provides a country with access to goods and services that it cannot produce locally, creating a wider choice for customers at competitive prices.
Improved Relations: Foreign trade widens the scope of communication between the trading nations. It makes sharing information and ideas easier, encourages goodwill, and leads to more cooperation and understanding. Also, it gives a reason to improve transportation between the countries for a smooth trade.
Improve Foreign Exchange Reserve: Some countries have ample resources, which promote production at comparatively cheaper costs. They can make many things to sell in their own country and on the international market to build up their foreign exchange reserves.
Increased Efficiency: International competition allows producers to make better goods at the lowest possible cost. It increases overall efficiency and provides benefits to consumers worldwide. It also strengthens the quality and standard of products available for consumption.
Relief at the Time of Emergency: Natural calamities like droughts, famines, earthquakes, or floods can adversely affect a country’s production capacity by hitting available resources, resulting in a supply deficit. Importing goods from other countries can help meet demand in such situations.
Increase in Employment Opportunities: Expanding the market for goods through trade increases employment opportunities. International trade generates employment by establishing industries to meet the manifold demands of various nations, contributing to reducing the unemployment rates in different countries.
Disadvantages
Taxes, Customs, and Duties: Customs and duties, along with additional shipping fees, make international products expensive and unaffordable, deterring potential customers.
Language Barrier: Even though there are translators, language still needs to improve in international trade. One can find poorly translated product descriptions that are prone to be misunderstood. In the same way, it’s hard to figure out the mystery behind the unquoted expression of products.
Poor Customer Service: Only some customers can be satisfied with the company’s products and services. In such a case, the process of return and refund is quite complicated and costly. After selling a product, most companies don’t care about customer complaints and think any flaws are the customer’s responsibility.
Risk of Uncertainty: International distribution of products can lead to illegal copying by competitors, making it difficult for producers to prosecute. Political risks and changing policies add to the uncertainty, making it challenging for producers to retain customers and sales globally.
Shortage in Domestic Markets: Exporting goods allows producers to earn more foreign currency and gain a cost advantage. Due to this reason, goods run short in domestic supply, causing inflation. It makes people angry and could cause problems in both domestic and international trade.
Economic Dependence: Most countries depend on imports and exports for their economic development. It provokes political & socio-economic implications and exploitation of the dependent government. The standard of living in such countries is comparatively low, further inducing poverty.
Unwanted Restrictions: Imposing restrictions on trade can lead to the smuggling of harmful goods. Such transactions can also lead to human trafficking by making the workers prone to manipulation and overwork with the most negligible benefits.
Understanding International Trade
International trade was key to the rise of the global economy. In the global economy, supply and demand—and thus prices—both impact and are impacted by global events.
Political change in Asia, for example, could result in an increase in the cost of labor. This could increase the manufacturing costs for an American sneaker company that is based in Malaysia, which would then result in an increase in the price charged for a pair of sneakers that an American consumer might purchase at their local mall.
Imports and Exports
A product that is sold to the global market is called an export, and a product that is bought from the global market is an import. Imports and exports are accounted for in the current account section of a country's balance of payments.
Global trade allows wealthy countries to use their resources—for example, labor, technology, or capital—more efficiently. Different countries are endowed with different assets and natural resources: land, labor, capital, technology, etc.
This allows some countries to produce the same good more efficiently; in other words, more quickly and at a lower cost. Therefore, they may sell it more cheaply than other countries. If a country cannot efficiently produce an item, it can obtain it by trading with another country that can. This is known as specialization in international trade.
Comparative Advantage
For example, England and Portugal have historically been used, as far back as in Adam Smith's The Wealth of Nations, to illustrate how two countries can mutually benefit by specializing and trading according to their own comparative advantages.1
Dimand, Robert W. "Adam Smith on Portuguese wine and English cloth." The European Journal of the History of Economic Thought, vol. 25, no. 6. 2018, pp. 1264-1281.
In such examples, Portugal is said to have plentiful vineyards and can make wine at a low cost, while England is able to more cheaply manufacture cloth given its pastures are full of sheep.2
According to the theory of comparative advantage, each country would eventually recognize these facts and stop attempting to make the product that was more costly to generate domestically in favor of engaging in trade. Indeed, over time, England would likely stop producing wine, and Portugal stop manufacturing cloth. Both countries would realize that it was to their advantage to redirect their efforts at producing what they were relatively better at domestically and, instead, to trade with each other in order to acquire the other.
These two countries realized that they could produce more by focusing on those products for which they have a comparative advantage. In such a case, the Portuguese would begin to produce only wine, and the English only cotton.
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 both products at lower costs. We can see then that for both countries, the opportunity cost of producing both products is greater than the cost of specializing.
Comparative advantage can contrast with absolute advantage. Absolute advantage leads to unambiguous gains from specialization and trade only in cases wherein each producer has an absolute advantage in producing some good.
If a producer lacked any absolute advantage, then they would never export anything. But we do see that countries without any clear absolute advantage do gain from trade because they have a comparative advantage.
According to international trade theory, even if a country has an absolute advantage over another, it can still benefit from specialization.
Origins of Comparative Advantage
The theory of comparative advantage has been attributed to the English political economist David Ricardo. Comparative advantage is discussed in Ricardo's book On the Principles of Political Economy and Taxation, published in 1817, although it has been suggested that Ricardo's mentor, James Mill, likely originated the analysis and slipped it into Ricardo's book on the sly.345
Comparative advantage, as we have shown above, famously showed how England and Portugal both benefit by specializing and trading according to their comparative advantages. In this case, Portugal was able to make wine at a low cost, while England was able to cheaply manufacture cloth. Ricardo predicted that each country would eventually recognize these facts and stop attempting to make the product that was more costly to generate.5
A more contemporary example of comparative advantage is China’s comparative advantage over the United States in the form of cheap labor. Throughout much of the 20th century, Chinese workers produced simple consumer goods at a much lower opportunity cost.6
The comparative advantage for the U.S. is in specialized, capital-intensive labor. American workers produce sophisticated goods or investment opportunities at lower opportunity costs. Specializing and trading along these lines benefit each country. However, it should be noted that Chinese manufactures are now able to produce goods that span all levels of the value chain, including high quality, higher cost products.
The theory of comparative advantage helps to explain why protectionism has been traditionally unsuccessful. If a country removes itself from an international trade agreement, or if a government imposes tariffs, it may produce an immediate local benefit in the form of new jobs; however, this is rarely a long-term solution to a trade problem.
Eventually, that country will grow to be at a disadvantage relative to its neighbors: countries that were already better able to produce these items at a lower opportunity cost.
The U.S. international trade deficit in September 2023 was $61.5 billion, meaning imports exceed exports.7
Criticisms of Comparative Advantage
Why doesn't the world have open trading between countries? When there is free trade, why do some countries remain poor at the expense of others? There are many reasons, but the most influential is something that economists call rent seeking. Rent seeking occurs when one group organizes and lobbies the government to protect its interests.
Say, for example, the producers of American shoes understand and agree with the free-trade argument but also know that cheaper foreign shoes would negatively impact their narrow interests. Even if laborers would be most productive by switching from making shoes to making computers, nobody in the shoe industry wants to lose their job or see profits decrease in the short run.
This desire could lead the shoemakers to lobby for special tax breaks for their products or extra duties (or even outright bans) on foreign footwear. Appeals to save American jobs and preserve a time-honored American craft abound—even though, in the long run, American laborers would be relatively less productive and American consumers relatively poorer as a result of such protectionist tactics.
Other Possible Benefits of Trading Globally
International trade not only results in increased efficiency but also allows countries to participate in a global economy, encouraging the opportunity for foreign direct investment (FDI). In theory, economies can thus grow more efficiently and become competitive economic participants more easily.
For the receiving government, FDI is a means by which foreign currency and expertise can enter the country. It raises employment levels and, theoretically, leads to a growth in the gross domestic product (GDP). For the investor, FDI offers company expansion and growth, which means higher revenues.
Free Trade vs. Protectionism
As with all theories, there are opposing views. International trade has two contrasting views regarding the level of control placed on trade between countries.
Free Trade
Free trade is the simpler of the two theories. This approach is also sometimes referred to as laissez-faire economics. With a laissez-faire approach, there are no restrictions on trade. The main idea is that supply and demand factors, operating on a global scale, will ensure that production happens efficiently. Therefore, nothing must be done to protect or promote trade and growth because market forces will do this automatically.
Protectionism
Protectionism holds that regulation of international trade is important to ensure that markets function properly. Advocates of this theory believe that market inefficiencies may hamper the benefits of international trade, and they aim to guide the market accordingly.
Protectionism exists in many different forms, but the most common are tariffs, subsidies, and quotas. These strategies attempt to correct any inefficiency in the international market.
As international trade opens up the opportunity for specialization, and thus more efficient use of resources, it has the 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. Thus, as it develops, so too must its participants.
What Are the Benefits of International Trade for a Business?
The benefits of international trade for a business are a larger potential customer base, meaning more profits and revenues, possibly less competition in a foreign market that hasn't been accessed as yet, diversification, and possible benefits through foreign exchange rates.
What Creates the Need for International Trade?
International trade arises from the differences in certain areas of each nation. Typically, differences in technology, education, demand, government policies, labor laws, natural resources, wages, and financing opportunities spur international trade.
What Are Common Barriers to International Trade?
The barriers to international trade are policies that governments implement to prevent international trade and protect domestic markets. These include subsidies, tariffs, quotas, import and export licenses, and standardization.
The Bottom Line
The world economies have become more intertwined through globalization and international trade is a major part of most economies. It provides consumers with a variety of options and increases competition so that businesses must produce cost-efficient and high-quality goods, benefiting these consumers.
Nations also benefit through international trade, focusing on producing the goods they have a comparative advantage in. Though some countries limit international trade through tariffs and quotas to protect domestic businesses, international trade has shown to benefit economies as a whole.
