Microeconomics and Pricing Questions

Multiple choice

Consider an economy with two goods, X and Y, and two consumers, A and B. The utility functions of the consumers are given by U_A(X, Y) = X + Y and U_B(X, Y) = 2X + Y. The initial allocation of goods is X_A = 10, Y_A = 10, X_B = 20, and Y_B = 20. Suppose that consumer A and consumer B agree to trade one unit of good X for one unit of good Y. Will this trade make the allocation Pareto efficient?

  1. Yes

  2. No
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The trade will make the allocation Pareto efficient because it makes both consumers better off. Consumer A will be better off because he will have more of good Y, which he values more than good X. Consumer B will be better off because he will have more of good X, which he values more than good Y.

The initial allocation of goods is X_A = 10, Y_A = 10, X_B = 20, and Y_B = 20. Suppose that consumer A and consumer B agree to trade two units of good X for one unit of good Y. Will this trade make the allocation Pareto efficient?

  1. Yes

  2. No
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The trade will not make the allocation Pareto efficient because it makes consumer A worse off. Consumer A will be worse off because he will have less of good X, which he values more than good Y. Consumer B will be better off because he will have more of good Y, which he values more than good X. However, the trade makes consumer A worse off, so it is not Pareto efficient.

Multiple choice

Consider an economy with two goods, X and Y, and two consumers, A and B. The utility functions of the consumers are given by U_A(X, Y) = X + Y and U_B(X, Y) = 2X + Y. The initial allocation of goods is X_A = 10, Y_A = 10, X_B = 20, and Y_B = 20. Suppose that the government imposes a price ceiling on good X. How will this affect the Pareto efficiency of the allocation?

  1. The allocation will become Pareto inefficient.

  2. The allocation will remain Pareto efficient.

  3. The effect of the price ceiling on Pareto efficiency is indeterminate.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The price ceiling on good X will make consumer A worse off because he will have to pay more for good X. This will reduce his utility. The price ceiling will also make consumer B worse off because he will have to pay more for good X. This will also reduce his utility. Therefore, the allocation will become Pareto inefficient.

Multiple choice

Consider an economy with two goods, X and Y, and two consumers, A and B. The utility functions of the consumers are given by U_A(X, Y) = X + Y and U_B(X, Y) = 2X + Y. The initial allocation of goods is X_A = 10, Y_A = 10, X_B = 20, and Y_B = 20. Suppose that the government imposes a price floor on good X. How will this affect the Pareto efficiency of the allocation?

  1. The allocation will become Pareto inefficient.

  2. The allocation will remain Pareto efficient.

  3. The effect of the price floor on Pareto efficiency is indeterminate.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The price floor on good X will make consumer A better off because he will be able to sell good X for a higher price. This will increase his utility. The price floor will also make consumer B worse off because he will have to pay more for good X. This will reduce his utility. Therefore, the allocation will become Pareto inefficient.

Multiple choice

Consider an economy with two goods, X and Y, and two consumers, A and B. The utility functions of the consumers are given by U_A(X, Y) = X + Y and U_B(X, Y) = 2X + Y. The initial allocation of goods is X_A = 10, Y_A = 10, X_B = 20, and Y_B = 20. Suppose that the government gives consumer A a lump-sum transfer of 10 units of money. How will this affect the Pareto efficiency of the allocation?

  1. The allocation will become Pareto inefficient.

  2. The allocation will remain Pareto efficient.

  3. The effect of the lump-sum transfer on Pareto efficiency is indeterminate.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The lump-sum transfer will make consumer A better off because he will have more money to spend on goods X and Y. This will increase his utility. The lump-sum transfer will not affect consumer B because he does not receive any money. Therefore, the allocation will remain Pareto efficient.

Multiple choice

What is the impact of excise duty on the price of a good?

  1. It increases the price of the good

  2. It decreases the price of the good

  3. It has no impact on the price of the good

  4. It depends on the elasticity of demand for the good
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Excise duty increases the price of a good because it is a tax levied on the production or sale of the good. The producer or seller of the good typically passes on the cost of the excise duty to the consumer in the form of a higher price.

Multiple choice

What is the efficient market hypothesis?

  1. The hypothesis that all available information is reflected in the prices of securities.

  2. The hypothesis that all available information is not reflected in the prices of securities.

  3. The hypothesis that the prices of securities are determined by supply and demand.

  4. The hypothesis that the prices of securities are determined by the intrinsic value of the underlying assets.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The efficient market hypothesis is the hypothesis that all available information is reflected in the prices of securities. This means that it is impossible to consistently beat the market by buying and selling securities.

Multiple choice

  1. Law of Supply

  2. Law of Demand

  3. Law of Diminishing Returns

  4. Law of Comparative Advantage
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The law of demand states that as the price of a good or service increases, the quantity demanded decreases, assuming other factors remain constant.
