Ricardian Theory and Opportunity Cost

The video introduces the Ricardian theory of comparative advantage, explaining that trade should be based on producing goods at a lower opportunity cost. It defines opportunity cost and uses a hypothetical example of the USA and UK to illustrate the concept. The video discusses the assumptions of the theory, such as perfect competition and no transport costs, and provides a diagram to show comparative advantage. It concludes with criticisms of the theory, noting its limitations in real-world applications.

What is the main idea behind the Ricardian Theory of Comparative Advantage?

• Countries should trade based on comparative advantage.

• Countries should trade based on absolute advantage.

• Countries should avoid trade to protect local industries.

• Countries should trade only with neighboring countries.

What does opportunity cost refer to in the context of this theory?

• The cost of importing goods from another country.

• The cost of choosing one alternative over another.

• The cost of labor in producing goods.

• The cost of producing goods at a higher price.

Which of the following is an assumption of the Ricardian Theory?

• There is perfect competition.

• Government intervention is necessary.

• Labor can move freely between countries.

• Multiple factors of production are considered.

In the hypothetical example, what is the opportunity cost for the USA to produce one mobile?

• Sacrifice of 0.5 tablets

• Sacrifice of 1.25 tablets

• Sacrifice of 0.8 tablets

• Sacrifice of 2 tablets

According to the example, which country has a lower opportunity cost in producing tablets?

• USA

• UK

• Neither has a lower opportunity cost

• Both have the same opportunity cost

Why should the USA focus on producing tablets according to the example?

• USA has a surplus of tablets.

• USA has a lower demand for tablets.

• USA is more efficient in producing tablets.

• USA has a higher opportunity cost in producing tablets.

What does the analysis of productive capacity reveal about the USA's efficiency?

• USA is equally efficient in producing both goods.

• USA is more efficient in producing tablets.

• USA is more efficient in producing mobiles.

• USA is less efficient in producing both goods.

Which of the following is a criticism of the Ricardian Theory?

• It considers multiple factors of production.

• It assumes perfect competition and full employment.

• It accurately predicts real-world trade patterns.

• It includes government intervention in its assumptions.

What is one limitation of the Ricardian Theory mentioned in the video?

• It assumes that transport costs are significant.

• It assumes that exchange rates are variable.

• It assumes that labor is the only factor of production.

• It assumes that there are more than two countries involved.

Why is it difficult to apply the Ricardian Theory in real life?

• Because it considers too many goods.

• Because it ignores the role of government.

• Because it requires perfect competition.

• Because it assumes variable exchange rates.
