Opportunity Cost and Comparative Advantage

Vidhi Kalra introduces the Comparative Advantage Theory, also known as Ricardian Theory, on her channel 5-Minute Economics. She explains the concept of opportunity cost and uses a baking example to illustrate how specialization can lead to increased production. The video discusses the assumptions of the theory, such as a two-country model and constant technology, and applies it to a hypothetical trade scenario between India and Nepal. The video concludes with a PPC diagram to visually represent the theory's application.

Who is credited with discovering the Comparative Advantage Theory?

• David Ricardo

• Adam Smith

• Milton Friedman

• John Maynard Keynes

What is opportunity cost?

• The difference between total revenue and total cost

• The total cost of production

• The next best alternative foregone

• The cost of producing one more unit of a good

In the baking example, what is Vidhi's opportunity cost of making one brownie?

• 2 pies

• 0.5 pies

• 1 pie

• 3 pies

What is the main assumption about labor in the Comparative Advantage Theory?

• Labor is the only factor of production

• Labor is mobile between countries

• Labor is immobile within countries

• Labor is not considered in the theory

In the example with India and Nepal, which country has a comparative advantage in producing laptops?

• Neither has an advantage

• Nepal

• Both have the same advantage

• India

How many tons of cotton does India give up to produce one laptop?

• 2 tons

• 4 tons

• 8 tons

• 0.5 tons

According to the Comparative Advantage Theory, which country should produce cotton in the India-Nepal example?

• Nepal

• Both should produce equally

• Neither should produce

• India

What does the PPC diagram help illustrate in the context of comparative advantage?

• The labor mobility between countries

• The opportunity cost and comparative advantage

• The absolute advantage of a country

• The total cost of production

In the PPC diagram, what indicates a comparative advantage?

• The larger gap on the x-axis

• The smaller gap on the x-axis

• The larger gap on the y-axis

• The smaller gap on the y-axis

What is the main benefit of specialization according to the Comparative Advantage Theory?

• Maximized total output and efficiency

• Increased production of all goods

• Reduced labor costs

• Elimination of trade barriers
