Test on Microeconomics Core Concepts and Problems

Question 1: Does a decrease in the price of pasta lead to changes in consumption decisions due to both income and substitution effects?

A. Ano

B. Ne

Explanation: The study materials explicitly ask to describe the income and substitution effects affecting the consumption decision when the price of pasta decreases, indicating that both effects are relevant in this scenario.

Question 2: Based on the provided job offer, where the hourly wage is €15 and an individual works 40 hours per week, resulting in 128 hours of free time, what is the weekly wage corresponding to point A in a diagram where free time is on the horizontal axis and weekly wage is on the vertical axis?

A. €15

B. €40

C. €128

D. €600

Explanation: The individual works 40 hours per week at an hourly wage of €15. Therefore, the weekly wage is 40 hours * €15/hour = €600.

Question 3: If Roast-Master increases its price, the demand for Bean-Point's coffee becomes more elastic.

A. Ano

B. Ne

Explanation: The study materials ask 'How does this affect the Elasticity of Demand for Bean-Point's coffee?' but do not provide an explicit answer or explanation for how an increase in Roast-Master's price affects Bean-Point's demand elasticity. Therefore, it cannot be confirmed that it makes the demand more elastic.

Question 4: Based on the provided study materials, which of the following statements is true regarding a hypothetical scenario involving farmers and a Nash Equilibrium?

A. The study materials describe a specific outcome that makes both farmers better off than the Nash Equilibrium.

B. The study materials explain why farmers would not choose an outcome that makes them both better off than the Nash Equilibrium.

C. The study materials include a table detailing farmer outcomes related to a Nash Equilibrium.

D. The study materials pose a question about whether an outcome exists where farmers are better off than the Nash Equilibrium, but do not provide the answer or specific scenario details.

Explanation: The study materials explicitly ask, 'Is there another outcome in the table that makes both farmers better off than the Nash Equilibrium? If yes, why don't they simply choose that outcome?' However, the materials do not provide the table, the specific outcomes, or the explanation for this scenario, only the question itself.

Question 5: Offering a 10% discount to Group B customers would increase Novels.com's total revenue from that group.

A. Ano

B. Ne

Explanation: For Group B, the volume of sales before the 10% discount was 1.5 million units and after the discount it was 1.7 million units. Assuming the price before the discount was P and after was 0.9P, the total revenue before was P * 1.5 million and after was 0.9P * 1.7 million = 1.53P million. Since 1.53P million is greater than 1.5P million, total revenue from Group B would increase with the discount. This implies that demand for Group B is elastic, meaning a price decrease leads to a proportionately larger increase in quantity demanded, thus increasing total revenue.
