The website provides an in-depth explanation of international trade, its significance, and its implications for global economies. It outlines key concepts like comparative advantage, which explains how countries benefit from specializing in goods they produce efficiently while trading for others. The site also discusses the benefits of international trade, such as expanding markets, improving competition, and fostering economic growth through foreign direct investment (FDI). Additionally, it addresses challenges like protectionism, rent-seeking behaviors, and trade barriers, emphasizing their impact on efficiency and global economic integration.

This website is highly relevant to international trade as it combines theoretical insights with practical examples, making complex economic concepts accessible and relatable. It highlights the dynamic nature of global markets, showing how factors like tariffs, trade agreements, and global supply chains shape trade outcomes. One particularly useful piece of information is the explanation of comparative advantage, illustrated through both historical (e.g., England and Portugal) and modern examples (e.g., China and the U.S.). This understanding is critical for policymakers, businesses, and students to grasp the benefits and challenges of global trade, as well as its potential to drive economic growth and innovation.

If you can walk into a supermarket and find Costa Rican bananas, Brazilian coffee, and a bottle of South African wine, you're experiencing the impacts of international trade.

International trade is the purchase and sale of goods and services by companies in different countries. Consumer goods, raw materials, food, and machinery all are bought and sold in the international marketplace.

International trade allows countries to expand their markets and access goods and services that otherwise may not have been available domestically. As a result of international trade, the market is more competitive. This ultimately results in more competitive pricing and brings a cheaper product home to the consumer.

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. 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.

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.

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.

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.

A more contemporary example of comparative advantage is China's comparative advantage over the United States in the form of cheap labor. Chinese workers produce simple consumer goods at a much lower opportunity cost.

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.

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.

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 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.

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.

This article on international trade explores the divergence between economists' and the public's views on trade, emphasizing its efficiency-enhancing nature. Economists view trade as a production tool, fostering specialization and resource optimization, unlike the general public's perception of trade as a competitive game. The piece also reviews historical trade theories, such as Ricardo’s comparative advantage and Heckscher-Ohlin's factor proportions and discusses modern perspectives like Krugman’s increasing returns theory.

The article is relevant for understanding trade's impact on global economic dynamics, showcasing how reduced trade barriers boost growth, particularly in developing countries. A key insight is the role of comparative advantage in promoting global efficiency and wealth creation.

# data[].attributes.attachment_link.readable_text
On the topic of international trade, the views of economists tend to differ from those of the general public. There are three principal differences. First, many noneconomists believe that it is more advantageous to trade with other members of one's nation or ethnic group than with outsiders. Economists see all forms of trade as equally advantageous. Second, many noneconomists believe that exports are better than imports for the economy. Economists believe that all trade is good for the economy. Third, many noneconomists believe that a country's balance of trade is governed by the "competitiveness" of its wage rates, tariffs, and other factors. Economists believe that the balance of trade is governed by many factors, including the above, but also including differences in national and investment.

The noneconomic views of trade all seem to stem from a common root: the tendency for human beings to emphasize tribal rivalries. For most people, viewing trade as a rivalry is as instinctive as rooting for their national team in Olympic basketball.

To economists, Olympic basketball is not an appropriate analogy for international trade. Instead, we see international trade as analogous to a production technique. Opening up to trade is equivalent to adopting a more efficient technology. International trade enhances efficiency by allocating resources to increase the amount produced for a given level of effort. Classical liberals, such as Richard Cobden, believed that could bring about world peace by substituting commercial relationships among individuals for competitive relationships between states.

History of Trade Theory

developed and published one of the first theories of international trade in 1817. "England," he wrote, may be so circumstanced, that to produce the cloth may require the labour of 100 men for one year; and if she attempted to make the wine, it might require the labour of 120 men for the same time....

The opportunity to trade with the painter enables the surgeon to paint her house by doing a few hours of surgery. Similarly, international trade enables one country to obtain cloth more cheaply by specializing in the production of wine and trading for cloth, rather than producing both goods for itself.

The Ricardo and Heckscher-Ohlin theories tend to predict clear patterns of specialization in trade. A country will focus on one type of industry for exports and another type of industry for imports. In fact, the types of industries in which a country exports and the types in which it imports are not dramatically different. This fact has led to the emphasis on another theory of trade, developed by Paul Krugman and others. The idea is that patterns of specialization develop almost by accident and that these patterns persist because of positive feedback. This is known as the increasing-returns model of international trade. "Increasing returns" means that the more of something you produce, the more efficient you get at producing it.

In the United States, for example, Detroit became an automobile-manufacturing center. Once the first large automaker located in Detroit, it was natural that other auto companies would be started there because it was easier to find employees with the right skills. Likewise, people with the skills to produce movies were first located in Hollywood. It became uneconomical to try to build an auto plant in Hollywood or a movie studio in Detroit. Thus, Detroit became an exporter of automobiles, and Hollywood became an exporter of movies. The same model of efficiency explains the international arena-why, for example, the Swiss specialize in watches and the Japanese in portable music players.

Gains from Trade

All of the economic theories of international trade suggest that it enhances efficiency. In this regard, international trade is like a new technology. It adds to the productive capacity of all countries that engage in trade. Some of the efficiency is due to comparative advantage, as in the Ricardo and Heckscher-Ohlin theories. In addition, some efficiency comes from taking advantage of increasing returns.

Trade based on comparative advantage should tend to benefit small countries more than large countries. That is because the benefits of comparative advantage are proportional to the difference between the relative prices in world markets and the relative prices that would prevail in home markets without trade. If that difference is large, then a country earns a large advantage from trade. If that difference is small, then there is only a small advantage from trade. Small countries are more likely than large countries to find that relative prices in the world market differ significantly from what would prevail in their home markets.

Another benefit from trade is that it promotes dynamism and innovation within an economy. Improvements in manufacturing quality and productivity in the United States in recent decades have been credited, in part, to the pressure of competition from and elsewhere.

An economy that is closed to trade is one in which inefficient industries and laggard firms are well protected. In fact, studies suggest that barriers to trade are a major cause of extreme underdevelopment. The countries that are most closed to trade tend to be the poorest in the world. Countries that have reduced trade barriers and increased the share of imports and exports in their economies tend to be among the fastest-growing nations.

According to a World Bank study, twenty-four developing countries that became more integrated into the world economy in the 1980s and 1990s had higher income growth, longer life expectancy, and better schooling. Per capita income in these countries, home to half the world's population, grew by an average of 5 percent in the 1990s compared with only 2 percent in rich countries. China, India, Hungary, and Mexico are among the countries that adopted policies that allowed their people to take advantage of global markets. As a result, they sharply increased the amount of their GDP accounted for by trade. Real wages in these countries rose and the number of poor people fell.

The study also points out that two billion people-particularly in sub-Saharan Africa, the Middle East, and the former Soviet Union-are in countries being left behind. These countries' integration into the world economy has not increased, and their ratio of trade to GDP has stagnated or fallen. Their economies have generally contracted, poverty has increased, and levels have risen less rapidly than in the more globalized countries.

The OECD countries, which together have more than $25 trillion in GDP, account for most of world trade. Poor countries account for less than $300 billion in GDP, which is less than one-tenth of world output, and thus account for only a miniscule fraction of world trade.

Purchasing Power Parity

If goods were perfectly tradable across borders, with no trade barriers or transactions costs, then there would be no reason for prices to differ. This gives rise to the idea of purchasing power parity, a theory of exchange-rate adjustment based on the law of one price.

If the same good sells for one hundred dollars in the United States and one hundred euros in Europe, then according to the law of one price the exchange rate between dollars and euros ought to be one. The theory of purchasing power parity is that this relationship holds for an overall market basket of goods and services.

Empirical tests tend to show only a weak tendency for exchange rates to move in the direction of purchasing power parity. This means that cross-border trade is not nearly friction free. The failure of purchasing power parity to hold, except perhaps in the long run, indicates that transportation costs, language-translation costs, and other factors limit the integration of global markets.

Capital Flows and the Balance of Trade

Imagine that all international trade took place in the form of barter of goods and services. If you wanted to buy a Japanese car, you would have to offer something of equivalent value in return. In that case, trade in goods and services would have to balance, and there would be no trade deficits.

Typically, one would expect wealthy countries to have excess saving and to invest in capital-poor countries. From this perspective, it is an anomaly that the United States is a capital importer and China is a capital exporter. However, the United States is a relatively attractive country in which to invest, and American policies tend to encourage consumption rather than saving.

Conclusion

Economic theory indicates that international trade raises the standard of living. A comparison between the performance of open and closed economies confirms that the benefits of trade in practice are significant.

The video by Dr. Azevedo explores how international trade fosters economic efficiency and mutual benefit among nations. It emphasizes the role of trade in promoting specialization, where countries focus on producing goods for which they have the greatest efficiency or lowest opportunity cost. By doing so, trade not only enhances global resource allocation but also supports economic interdependence and cooperation. The video also touches on how these principles translate into real-world policies and decisions, such as the structuring of trade agreements and the reduction of trade barriers.

This video is particularly relevant for understanding the mechanics of international trade as it relates to both theory and practice. Its straightforward explanation of opportunity cost and its impact on trade decisions is especially insightful for learners and professionals. For example, it illustrates how nations can achieve mutual benefits by focusing on comparative advantage, even when one country is more efficient in producing all goods. This concept is vital for crafting strategies that leverage trade to optimize economic growth and international partnerships.

We were particularly surprised by how international trade fosters economic growth and innovation not only through comparative advantage but also by leveraging increasing returns. For example, as industries grow in specific regions, such as Detroit with automobiles or Hollywood with films, their efficiency improves due to concentrated expertise and infrastructure. This dynamic reveals how trade shapes economies beyond traditional theories. Additionally, the stark difference in development outcomes between open and closed economies, especially in developing nations, highlights trade’s transformative potential.

This video explains the rudimentary knowledge of international trade. International trade is an agreement that prioritizes world peace through economic interdependency between nations. This is achieved when a nation focuses on producing what they are good at on a large scale, and export to countries where there is demand, but have less of a competitive advantage to produce them. Importing products from nations that cannot be efficiently produced at home is a win for both sides. This can include minerals and natural resources, agricultural products, knowledge, technology etc.

We chose this website because it breaks down the barrier between economic professionals and someone who genuinely has an interest in understanding how international trade works. Simplifying the concept of international trade to the knowledge of everyone.
