Learning Objective 1: To understand theories of international trade.
Why do countries trade? Countries trade in order to meet certain economic objectives, but they struggle with questions on what, how much, and with whom they should trade. They need to ensure that their decisions on what to produce make sense from an efficiency standpoint, and whether there are ways to improve competitiveness.
Some countries allow market forces to determine trade relations, others intervene to control the process.
This Figure shows that trade in goods and services and the movement of the production factors are the means by which countries are linked internationally.
Theories that explain trade patterns explore how much countries depend on trade, in what products, and with which countries. Some theories suggest that governments should influence trade patterns, other support a laissez-faire approach.
This Figure shows the major trade theories and their emphases. Managers can use the theories to predict and understand how government policy decisions could affect business competitiveness.
Factor mobility is also an important issue in trade because it influences a nation’s competitiveness. The three factors of production are land, labor, and capital.
Some theories including mercantilism and neomercantilism explore how governments can interfere with trade flows in order to achieve certain national objectives.
The mercantilist theory suggests that countries should try to achieve a favorable balance of trade. This theory was the basis of economic thought from 1500 to 1800.
Under mercantilism, governments restricted imports and subsidized the production of goods that would otherwise not be competitive in domestic or export markets.
Countries with a neomercantilist approach seek a favorable balance of trade, but do so in order to achieve some social or political objective.
Why shouldn’t countries just be self-sufficient? According to the theories of absolute and comparative advantage, specializing in the things a country does best and trading for everything else can be beneficial.
Adam Smith’s theory of absolute advantage suggested that a nation’s wealth is based on its available goods and services rather than on gold. Therefore, if trade is unrestricted, a country can specialize in what it can produce most efficiently, and trade for everything else.
Consumers benefit from free trade and specialization with lower prices and more choices.
A country’s advantage in the production of a particular good may be a result of a natural advantage like climate, or an acquired advantage like technology.
This Figure illustrates the production possibilities for two countries under the conditions of absolute advantage. Notice that with free trade and specialization both countries benefit.
What happens when a country can produce all products at an absolute advantage? Well, there are still gains to be made from specialization and free trade.
David Ricardo explored this issue in 1817 and discovered that gains from trade occur even in a country that has an absolute advantage in all products because the country gives up less efficient output in order to focus on more efficient output.
This Figure illustrates the production possibilities for two countries under the conditions of comparative advantage. Notice that by specializing in the production of goods in which a country has a comparative advantage and trading for goods in which a country has an absolute disadvantage both countries still gain.
Learning Objective 2: To explain how free trade improves global efficiency.
While the theories of specialization – absolute advantage and comparative advantage – offer policymakers a greater understanding of free trade, they are based on a number of assumptions that may not always be valid.
Specifically, the theories assume that full employment exists, that economic efficiency is the primary goal of countries, that the division of gains is acceptable to both countries, that the world is composed of only two countries and two products, that there are no transportation costs, that advantages are static, and that while resources can move freely within a country, they are immobile internationally.
Keep in mind that the theories can apply to trade in services as well as trade in products and that they apply to situations in which multi-country production takes place.
Learning Objective 3: To identify factors affecting national trade patterns.
Every country produces so-called nontradeable goods like haircuts. When it comes to tradeable goods though, country size can be a determining factor in the production choice. Larger countries typically have more varied climates and natural resources and are usually more self-sufficient than smaller countries.
Moreover, because production and market centers in large countries are more likely to be located farther away from other countries, transportation costs are higher.
What types of products does a country trade? We can use the factor proportions theory to help answer that question. The theory suggests that factor costs are determined by a country’s relative endowments of land, labor, and capital. These costs then determine which goods can be produced most efficiently.
Keep in mind though that not all production factors are equal especially when it comes to labor. Moreover, how a product is produced – with capital or labor – is important as is the size of the production run required for greatest efficiency.
This Figure shows the changing composition of world trade. Most new products are developed in industrialized countries.
With whom do countries trade? Well, developed countries largely trade with other developed countries. Companies create new products in response to market conditions in their home market, and then look for markets that are close to home and most similar to what they’re accustomed to.
Learning Objective 4: To explain why a country’s export capabilities are dynamic.
How do countries develop, maintain, and lose their competitive advantages? The international product life cycle theory, or PLC, offers one explanation.
According to the PLC, companies manufacture products initially in the country where they were developed and researched – typically a developed country. Later, production shifts to foreign locations, and in the later stages of the product’s life, to developing economies.
The theory is based on four stages: introduction, growth, maturity, and decline.
This Figure provides more details on exactly what occurs at each stage in a product’s life cycle. Keep in mind that while the theory holds for many products, it does not explain all products. In fact, today, many products are introduced at home and abroad simultaneously. Moreover, because costs drive production decisions, the initial production location may or may not be in the home country.
Another theory that helps explain why some countries have developed and sustained different competitive advantages is the diamond of national advantage theory. According to this theory, four conditions must be favorable for an industry: demand conditions, factor conditions, related and supporting industries, and firm strategy, structure, and rivalry.
This Figure provides more details on each factor that makes up the diamond of national advantage. Keep in mind though, that the existence of all four factors does not guarantee that an industry will develop, nor is it necessary given globalization. For example, today, because capital and managers are internationally mobile, it may not be necessary to depend on domestic factor conditions. Similarly, thanks to freer trade and advances in transportation, local related and supporting are not as important.
Learning Objective 5: To understand why production factors, especially labor and capital, move internationally.
The mobility of capital, technology, and people affects trade and relative competitive positions. The factor mobility theory helps explain why production factors move, and what that means for transforming factor endowments, as well as the impact of international factor mobility on world trade.
The mobility of capital and population plays a role in a country’s factor endowments. For some countries, the movement of people can be significant. In Luxembourg for example, foreign- born people make up some 20 percent of the total population, but in Japan, account for just 2 percent.
Outward migration can have a negative impact on a country if it involves the departure of educated people, but if these people then send remittances back home, it can have a positive effect.
Finally, keep in mind that the movement of capital and labor is intertwined – think for example, about skilled foreign workers.
Learning Objective 6: To explain the relationship between foreign trade and international factor mobility.
What is the relationship between trade and factor mobility? In general, if free trade is coupled with the free moving factors of production, the most efficient resource allocation should occur.
The most abundant factors should move to areas of scarcity.
This Figure illustrates the substitutability of trade and factor movements under different scenarios.
When companies invest abroad they often stimulate exports from their home country through sales of components, equipment, and complimentary products.
Will the trend toward the freer movement of trade and production factors continue?
We don’t know what the future will hold, but these four interrelated factors could cause product trade to become relatively less significant in the future.
