Comparative Advantage and International Trade Dynamics

The video explains David Ricardo's law of comparative advantage, a key concept in international trade theory. It distinguishes between absolute and comparative advantage, emphasizing the importance of opportunity cost. Using India and Ghana as examples, the video illustrates how countries should specialize in goods they can produce at the lowest opportunity cost. It also covers the role of exchange rates in making trade mutually beneficial and discusses the factors that determine a country's comparative advantage.

What is the key difference between absolute advantage and comparative advantage?

• Absolute advantage is about trading more, while comparative advantage is about trading less.

• Absolute advantage is about using more resources, while comparative advantage is about using fewer resources.

• Absolute advantage is about producing at a lower cost, while comparative advantage is about producing more.

• Absolute advantage is about producing more with fewer resources, while comparative advantage focuses on lower opportunity cost.

In the example of India and Ghana, which country has the comparative advantage in cotton production?

• Ghana, because it produces cotton faster.

• Ghana, because it gives up less to produce cotton.

• India, because it can produce more cotton.

• India, because it has more resources.

What does the Production Possibility Curve (PPC) illustrate in the context of comparative advantage?

• The maximum production of one good only.

• The trade-off between two goods and the opportunity cost.

• The total resources available in a country.

• The absolute advantage of a country.

According to the theory, what should a country do if it has a comparative advantage in a good?

• Produce that good only for domestic consumption.

• Avoid producing that good to focus on other goods.

• Produce and trade that good freely with other countries.

• Trade that good only with countries that have an absolute advantage.

How can a country determine its comparative advantage using PPCs?

• By finding the axis with the smallest gap between PPCs.

• By analyzing the absolute advantage of both countries.

• By identifying the axis with the largest gap between PPCs.

• By comparing the total production of both countries.

Why is a suitable rate of exchange crucial for mutually beneficial trade?

• It ensures that the trade benefits both countries by lying between their opportunity cost ratios.

• It allows countries to trade without considering opportunity costs.

• It allows one country to dominate the trade.

• It ensures that both countries can trade without any cost.

What happens if the exchange rate is outside the opportunity cost ratios?

• Trade becomes more beneficial for both countries.

• Trade becomes less beneficial or not beneficial at all.

• Trade remains unaffected.

• Trade becomes impossible.

What determines whether a country has a comparative advantage in a particular good?

• The quantity and quality of its factor endowments.

• The country's population size.

• The country's political stability.

• The country's geographical size.

What is the role of factor endowments in determining comparative advantage?

• They have no impact on comparative advantage.

• They influence the opportunity cost of producing goods.

• They only affect the quality of goods produced.

• They determine the absolute advantage of a country.

What is the benefit of having a mutually beneficial exchange rate?

• It allows countries to consume beyond their PPC.

• It reduces the need for specialization.

• It increases the absolute advantage of a country.

• It eliminates the need for opportunity cost calculations.
