Comparative Advantage and Trade Theories

The video discusses the comparative advantage theory of international trade, introduced by David Ricardo in 1817. It builds on Adam Smith's absolute advantage theory, explaining how countries can benefit from trade even if one has an absolute advantage in producing all goods. The video uses a numerical example involving India and England to illustrate the concept. Criticisms of the theory, such as its assumptions about labor and transportation costs, are also addressed. Despite these criticisms, the theory remains a cornerstone of international trade economics.

Who introduced the Comparative Advantage Theory?

• Milton Friedman

• David Ricardo

• Adam Smith

• John Maynard Keynes

What is the main idea behind Adam Smith's Absolute Advantage Theory?

• Countries should produce goods they can make most efficiently.

• Countries should produce goods they have a comparative advantage in.

• Countries should trade only if they have an absolute advantage in all goods.

• Countries should focus on self-reliance.

According to Ricardo's theory, how can a country with an absolute disadvantage still benefit from trade?

• By avoiding trade altogether.

• By specializing in goods with less competitive disadvantage.

• By focusing on self-reliance.

• By producing goods it has an absolute advantage in.

In the numerical example, which commodity does India have a comparative advantage in?

• Cloth

• Wheat

• Both cloth and wheat

• Neither cloth nor wheat

What does England gain by exporting cloth to India in the example?

• More labor than it would domestically

• More money than it would domestically

• More cloth than it would domestically

• More wheat than it would domestically

Which assumption of the Comparative Advantage Theory is criticized for being unrealistic?

• Labor is the only factor of production.

• Trade is always beneficial.

• Countries have infinite resources.

• All countries have the same technology.

Why is the assumption of labor immobility criticized in Ricardo's theory?

• Labor is always homogeneous.

• Labor is the only factor of production.

• Labor is actually mobile among nations.

• Labor costs are negligible.

What is a major criticism regarding the transportation costs in the Comparative Advantage Theory?

• Transportation costs are too high to consider.

• Transportation costs are ignored in the theory.

• Transportation costs are the only factor considered.

• Transportation costs are always constant.

Despite its criticisms, why is the Comparative Advantage Theory still relevant?

• Many countries still engage in trade based on it.

• It considers all factors of production.

• It is the most recent theory.

• It is the only theory of international trade.

What is a potential drawback of countries focusing on self-reliance according to the theory?

• It increases the efficiency of production.

• It reduces transportation costs.

• It makes the Comparative Advantage Theory irrelevant.

• It leads to higher international trade.
