Q2.10: If the economy is operating at point C, which one of the following is the opportunity cost of producing an additional 15 units of bacon?

Background

Topic: Production Possibilities Frontier (PPF) and Opportunity Cost

This question tests your understanding of how opportunity cost is represented on a PPF, specifically when moving between points and increasing production of one good.

Key Terms and Formulas

• Production Possibilities Frontier (PPF): A curve showing the maximum attainable combinations of two products that may be produced with available resources and technology.

• Opportunity Cost: The value of the next best alternative foregone when a choice is made.

Step-by-Step Guidance

1. Identify the coordinates for point C on the PPF (units of eggs and units of bacon).

2. Find the point on the PPF where bacon production increases by 15 units from point C (look for the corresponding point along the curve).

3. Calculate the decrease in eggs as you move from point C to the new point with more bacon. This decrease represents the opportunity cost.

4. Compare the change in eggs to the change in bacon to determine the opportunity cost per 15 units of bacon.

Q3.8: From the production data, which one of the following statements can be made about absolute advantage?

Background

Topic: Absolute Advantage in International Trade

This question tests your ability to interpret production data and identify which country has an absolute advantage in producing each good.

Key Terms and Formulas

• Absolute Advantage: The ability of a country to produce more of a good with the same resources than another country.

Step-by-Step Guidance

1. Compare the output per worker per month for food between Australia and Korea.

2. Compare the output per worker per month for electronics between Australia and Korea.

3. Determine which country produces more of each good with the same resources.

4. Identify which country has an absolute advantage in food and which in electronics.

Q3.17: For which one of the following does Argentina have a comparative advantage in production?

Background

Topic: Comparative Advantage and Production Possibilities

This question tests your understanding of comparative advantage using PPFs for two countries and two goods.

Key Terms and Formulas

• Comparative Advantage: The ability of a country to produce a good at a lower opportunity cost than another country.

• Opportunity Cost: The amount of one good that must be given up to produce more of another good.

Step-by-Step Guidance

1. Calculate the opportunity cost of producing beef in Argentina and Peru using their PPFs.

2. Calculate the opportunity cost of producing fruit in Argentina and Peru.

3. Compare the opportunity costs for each good between the two countries.

4. Identify which country has the lower opportunity cost for each good, indicating comparative advantage.

Q4.5: Referring to the graph above, which one of the following describes the initial equilibrium price and quantity?

Background

Topic: Market Equilibrium in Supply and Demand

This question tests your ability to read a supply and demand graph and identify the equilibrium point.

Key Terms and Formulas

• Equilibrium Price: The price at which quantity demanded equals quantity supplied.

• Equilibrium Quantity: The quantity at which supply and demand intersect.

Step-by-Step Guidance

1. Locate the intersection point of the supply and demand curves on the graph.

2. Read the price (P) and quantity (Q) values at the intersection.

3. Match these values to the answer choices provided.

4. Verify that the intersection represents the equilibrium point.

Q4.9: Referring to the graph above, which one of the following describes the initial equilibrium price and quantity?

Background

Topic: Market Equilibrium in Supply and Demand

This question tests your ability to interpret a supply and demand graph for hand-held calculators and find the equilibrium.

Key Terms and Formulas

• Equilibrium Price: The price at which quantity demanded equals quantity supplied.

• Equilibrium Quantity: The quantity at which supply and demand intersect.

Step-by-Step Guidance

1. Find the intersection of the supply curve (S1) and the demand curve (D) on the graph.

2. Read the price (P) and quantity (Q) at the intersection point.

3. Compare these values to the answer choices given.

4. Confirm that this intersection is the equilibrium point.
