Trade and Comparative Advantage Concepts

The video tutorial explains how trade based on comparative advantage can increase world output, allowing countries to consume beyond their production possibilities curve (PPC). It uses a case study of a less developed country (LDC) and a developed country (DC) to illustrate trade benefits. The tutorial discusses how trade shifts the consumption possibilities frontier (CPF) outward, enabling higher consumption levels. Empirical evidence supports trade's positive impact on welfare and income, though diminishing returns and transport costs can limit benefits. Specialization is rarely complete due to these factors.

What is the primary benefit of trade according to the concept of comparative advantage?

• It reduces the cost of production.

• It enables countries to consume beyond their PPC.

• It allows countries to produce more goods.

• It increases the number of trading partners.

In the example provided, which country has a comparative advantage in wheat production?

• The less developed country (LDC)

• Neither country

• Both countries

• The developed country (DC)

Before trade, how much cloth does the LDC consume?

• 200 meters

• 400 meters

• 800 meters

• 600 meters

What is the assumed terms of trade between cloth and wheat?

• 2 meters of cloth for 1 kg of wheat

• 1 meter of cloth for 1 kg of wheat

• 1 meter of cloth for 3 kg of wheat

• 1 meter of cloth for 2 kg of wheat

How does trade affect the consumption possibilities frontier (CPF) for both countries?

• It makes the CPF steeper.

• It makes the CPF flatter.

• It shifts the CPF inward.

• It shifts the CPF outward.

What does the World Trade Organization estimate about the removal of all trade barriers?

• It would increase world income by 10%.

• It would increase world income by 6%.

• It would have no effect on world income.

• It would decrease world income by 6%.

What is a potential limitation of trade due to the diminishing marginal rate of substitution?

• Returns will always increase.

• Returns are unlikely to be constant.

• Returns will always decrease.

• Returns are likely to be constant.

Why might complete specialization not be practical for countries?

• It increases the cost of goods.

• It may not utilize all resources efficiently.

• It requires too much labor.

• It leads to higher transport costs.

What is one reason trade might not occur despite comparative advantage?

• High production costs

• Insufficient labor

• Excessive transport costs

• Lack of demand

Why might Singapore not devote all its resources to high-value-added services?

• It lacks the necessary technology.

• It would increase unemployment.

• It would lead to inefficient resource use.

• It has no comparative advantage in services.
