Question

An argument frequently used against free trade is that it throws Americans (or Germans or Italians) out of work and lowers the wages of those who remain employed. It is argued that American labor cannot compete against cheap, exploited, foreign labor. Evaluate this argument using the principle of comparative advantage.

Short answer

In conclusion, the argument against free trade may have some validity in the short term, as some domestic workers could lose jobs and experience wage reductions. However, by applying the principle of comparative advantage, we can see that the long-term benefits of international trade, such as increased production, resource reallocation, and higher wages, should outweigh these negative impacts. To ensure workers benefit from free trade, it is crucial for governments to provide support such as job training and educational programs to aid workers in transitioning to new industries.

Step-by-step solution

Understanding the principle of comparative advantage

The principle of comparative advantage states that countries should specialize in producing goods and services in which they have a lower opportunity cost. In other words, they should produce goods and services they are relatively more efficient at, even if their absolute ability to produce is not necessarily the highest.

Application of comparative advantage to free trade

We will evaluate the argument against free trade by applying the principle of comparative advantage. Suppose we have two countries: the United States (high-wage country) and a low-wage foreign country. Each country has the following opportunities to produce two goods (X and Y): USA: - One unit of good X requires 10 labor hours - One unit of good Y requires 20 labor hours Low-wage Country: - One unit of good X requires 30 labor hours - One unit of good Y requires 60 labor hours From these data, we can calculate the opportunity costs for producing the goods in both countries: USA: - Opportunity cost of good X: 10/20 = 0.5 units of good Y - Opportunity cost of good Y: 20/10 = 2 units of good X Low-wage Country: - Opportunity cost of good X: 30/60 = 0.5 units of good Y - Opportunity cost of good Y: 60/30 = 2 units of good X In this case, the opportunity costs are the same in both countries. However, the United States has an absolute advantage in producing both goods as it requires fewer labor hours to make the products. Despite this absolute advantage, the principle of comparative advantage suggests that both countries should specialize in the goods they have a lower opportunity cost in producing and engage in international trade.

Results of free trade

Here are the results when free trade is allowed between the two countries: 1. Specialization: The United States will specialize in producing good X, while the low-wage country specializes in good Y. Through trade, both countries can then obtain the other product more efficiently. 2. Increase in output: Total output of goods X and Y will increase due to each country specializing and trading. Consequently, consumers in both countries will have access to more goods at lower prices. 3. Reallocation of labor: Domestic laborers in industries with higher opportunity costs may lose their jobs. However, the resources and employees should eventually be reallocated to sectors where the country has a comparative advantage, leading to higher overall employment levels. 4. Wage adjustments: Although in the short term, some workers may experience job losses and lower wages, long-term wage adjustments and shifts to industries with comparative advantages will lead to overall higher wages and increased productivity.

Conclusion

Using the principle of comparative advantage, we can conclude that the argument against free trade might not be entirely valid. While it is true that some domestic workers may lose jobs and experience wage reductions in the short term, the long-term benefits of international trade (increased production, reallocation of resources, and higher wages) should outweigh those temporary negative impacts. However, it's essential for governments to provide support (e.g., job training, educational programs) to assist workers in transitioning to new industries and benefiting from the advantages of free trade.

Key concepts

Economic Principles

Economic principles play a crucial role in understanding how societies allocate their scarce resources. These principles are rooted in the concept that resources are limited, and therefore, choices must be made about their use. The principle of comparative advantage illustrates precisely that, as it informs us on how to make such choices most efficiently in order to maximize output and overall economic welfare.

Considering the application in free trade, economic principles enable countries to evaluate the benefits and costs associated with producing different goods and services. By following these fundamental concepts, countries can optimize their production based on their resources and thus, engage beneficially in the global market.

Opportunity Cost

Opportunity cost is a key concept in economics that refers to the next best alternative foregone when a choice is made. Simply put, it's what is given up to do or acquire something else. In the context of international trade and comparative advantage, understanding opportunity costs allows countries to determine which goods they can produce at the lowest relative cost.

In the exercise solution, by calculating the opportunity costs for producing goods X and Y, we see that each country should specialize in the production of the good for which it has the lower opportunity cost, despite how it compares in absolute terms. This concept supports the argument that instead of competing solely on wage levels, countries should trade based on where they hold a comparative efficiency, ensuring that all involved parties benefit from the trade.

International Trade

International trade describes the exchange of goods and services between countries. It is the backbone of the global economy, enabling countries to expand their markets and pursue economic growth beyond their borders.

When countries engage in free trade, they benefit from the concept of comparative advantage by specializing in the production of goods they can make most efficiently. Thus, trade allows for an increase in the overall availability of goods and can lead to a higher standard of living, as seen in our exercise where both countries end up with more goods at possibly lower prices. However, it also leads to labor market adjustments and requires countries to address the potential short-term impacts on employment and wages.

Labor Market Adjustments

Labor market adjustments occur when changes in the economic environment cause shifts in the demand for labor across industries. Free trade may lead to certain industries shrinking and others growing, as countries specialize according to their comparative advantage.

This adjustment process can be challenging for workers who find their skills in less demand, as outlined in steps 3 and 4 of the solution. In the long term, though, the labor market should adjust, with workers transitioning into industries where the country has a comparative advantage, potentially leading to improved employment levels and wages. Nevertheless, it's crucial for policymakers to facilitate these transitions with appropriate support and training programs.

Absolute vs Comparative Advantage

Understanding the difference between absolute and comparative advantage is essential in international trade. An absolute advantage occurs when a country can produce a good using fewer resources than other nations. Comparative advantage, on the other hand, exists when a country can produce a good at a lower opportunity cost relative to others.

The exercise demonstrated that even if a country, like the United States in this case, has an absolute advantage in producing both goods, it may not be the most efficient allocation of resources to do so. Instead, engaging in trade based on comparative advantages allows countries to specialize and maximize their production potential. This economic interdependence can lead to more efficient global production and a higher level of overall economic welfare.
