የምዕራፍ 4 የመልመጃ ጥያቄዎች

በዚህ ምዕራፍ ላይ የተጻፉ 10 የምርጫ ጥያቄዎች፣ እያንዳንዳቸው መልሱና ምክንያቱ አላቸው። መልሱን ከመክፈትዎ በፊት ይሞክሩ። ጥያቄዎቹ በእንግሊዝኛ ናቸው።

ጥያቄ 1

In a perfectly competitive market, what is the shape of the demand curve faced by an individual firm?

  1. A.Vertical line
  2. B.Horizontal line
  3. C.Downward-sloping line
  4. D.Inverse U-shaped curve
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ B Horizontal line

ምክንያቱ

An individual firm under perfect competition is a price taker and can sell any quantity at the established market price. Therefore, it faces a completely horizontal demand curve.

ጥያቄ 2

Which market structure consists of a single seller producing a commodity for which there are no close substitutes?

  1. A.Oligopoly
  2. B.Monopolistic competition
  3. C.Pure monopoly
  4. D.Perfect competition
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ C Pure monopoly

ምክንያቱ

A pure monopoly exists when only one firm produces and supplies a product with no close substitutes, making the firm and the industry one and the same.

ጥያቄ 3

What is a duopoly?

  1. A.A market with no barriers to entry and exit
  2. B.A market where one single firm controls all strategic inputs
  3. C.A market structure with thousands of small sellers
  4. D.A special case of oligopoly in which there are only two firms
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ D A special case of oligopoly in which there are only two firms

ምክንያቱ

As defined in the textbook, a duopoly is the simplest form of oligopoly, where exactly two firms operate in the industry.

ጥያቄ 4

In a perfectly competitive market, what is the correct relationship between price (P), average revenue (AR), and marginal revenue (MR)?

  1. A.P = AR = MR
  2. B.P > AR > MR
  3. C.MR > AR = P
  4. D.AR > P > MR
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ A P = AR = MR

ምክንያቱ

Because a competitive firm sells every unit at the same market price, the additional revenue from each extra unit equals the price, which also equals average revenue: AR = MR = P.

ጥያቄ 5

A farmer sells 50 quintals of wheat in a perfectly competitive market at a price of 3,000 birr per quintal. What are the farmer's total revenue (TR) and average revenue (AR)?

  1. A.TR = 150,000 birr and AR = 3,000 birr
  2. B.TR = 150,000 birr and AR = 50 birr
  3. C.TR = 3,000 birr and AR = 150,000 birr
  4. D.TR = 75,000 birr and AR = 1,500 birr
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ A TR = 150,000 birr and AR = 3,000 birr

ምክንያቱ

Total revenue is price times quantity: 3,000 birr * 50 = 150,000 birr. Average revenue is total revenue divided by quantity: 150,000 / 50 = 3,000 birr (which equals the price).

ጥያቄ 6

According to the textbook, why does Ambo Mineral Water have monopoly power over its natural mineral water?

  1. A.Due to foreign import quotas
  2. B.Due to ownership of a strategic or key input
  3. C.Due to facing a horizontal demand curve
  4. D.Due to the absence of fixed costs
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ B Due to ownership of a strategic or key input

ምክንያቱ

Ambo Mineral Water maintains monopoly power because it owns and controls the natural mineral water source, which is a strategic key raw material.

ጥያቄ 7

Why is the demand curve faced by a monopolistically competitive firm flatter than that of a pure monopoly?

  1. A.Because entry into the market is completely blocked
  2. B.Because the firm sells homogeneous products
  3. C.Because the firm faces rivals that sell close substitute products
  4. D.Because the firm is a price taker
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ C Because the firm faces rivals that sell close substitute products

ምክንያቱ

A pure monopoly has no rivals, while a monopolistically competitive firm competes against many rivals offering close substitutes, making its demand curve flatter (more price elastic).

ጥያቄ 8

In an oligopoly market such as the cement or sugar industry in Ethiopia, what key feature means one firm's actions directly affect its competitors?

  1. A.Price taking behavior
  2. B.Free entry and exit
  3. C.Perfect market information
  4. D.Mutual interdependence
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ D Mutual interdependence

ምክንያቱ

In an oligopoly, there are only a few dominant firms. As a result, they are mutually interdependent: any price or output decision made by one firm directly influences all rival firms.

ጥያቄ 9

If a monopoly firm faces a linear demand curve given by P = a - bQ, what is the formula for its total revenue (TR)?

  1. A.TR = a - bQ<sup>2</sup>
  2. B.TR = aQ - bQ<sup>2</sup>
  3. C.TR = aQ - bQ
  4. D.TR = a/Q - b
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ B TR = aQ - bQ<sup>2</sup>

ምክንያቱ

Total revenue is price multiplied by quantity: TR = P * Q. Substituting (a - bQ) for P gives TR = (a - bQ) * Q = aQ - bQ2.

ጥያቄ 10

A monopolist sells 4 units of a product at 7 birr each (TR = 28 birr). To sell 5 units, the price is lowered to 6 birr each (TR = 30 birr). What is the marginal revenue (MR) of the 5th unit?

  1. A.1 birr
  2. B.6 birr
  3. C.2 birr
  4. D.7 birr
መልሱንና ምክንያቱን ያሳዩ

መልስ፦ C 2 birr

ምክንያቱ

Marginal revenue is the change in total revenue resulting from selling one extra unit: MR = TR(5) - TR(4) = 30 birr - 28 birr = 2 birr.
