Question 9

A cartel refers to:

Accepted Answer

A cartel is a group of independent market participants who collude with each other in order to improve their profits and dominate the market by fixing prices, limiting supply, or other means.

Question 10

A group of producers that collude to restrict the quantity of output to maximize profits is called a:

Accepted Answer

A cartel is a group of independent market participants who collude with each other in order to improve their profits and dominate the market by fixing prices, limiting supply, or other means. This definition directly matches the description given in the question.

Question 11

A market where two large firms dominate is known as a:

Accepted Answer

A duopoly is a market structure where two companies have dominant control over an industry, which is the scenario described.

Question 12

In which one of the following markets do firms face a horizontal demand curve?

Accepted Answer

In a perfectly competitive market, firms face a horizontal demand curve because each firm is a price taker, meaning they can sell as much as they want at the market price but cannot influence the price by their own actions. This implies that the demand curve they face is perfectly elastic.

Question 13

In which one of the following markets do firms NOT face a downward-sloping demand curve?

Accepted Answer

The answer of In which one of the following markets...

Question 14

Firms that have market power face a _____ demand curve.

Accepted Answer

Firms with market power face a downward-sloping demand curve because they can set prices above marginal cost, and the quantity demanded decreases as the price increases.

Question 15

In any type of market, the profit per unit of output for a firm is equal to:

Accepted Answer

Profit per unit is calculated as the price at which the good is sold minus the average total cost of producing that good. This difference gives the profit earned on each unit sold.

Question 16

If a monopolist that is maximizing its profits charges a price of $16, has an average total cost of $10 and a marginal cost of $8, and sells 50 units of output, then its marginal revenue is _____, and its profit is:

Accepted Answer

For a monopolist maximizing profit, marginal revenue (MR) equals marginal cost (MC), so MR is $8. Profit is calculated as (Price - Average Total Cost) * Quantity = ($16 - $10) * 50 = $300.

Question 17

The difference between the price of a good and the average total cost of producing it is the:

Accepted Answer

The difference between the price of a good and the average total cost of producing it is the profit per unit. This is because profit per unit is calculated by subtracting the cost to produce one unit of a good (average total cost) from the selling price of that good.

Question 18

Why is the marginal revenue for a monopolist different from the price or the average revenue? Given this, show why the profit-maximizing quantity for a monopolist is different from the socially optimal output. Provide a graph for your explanation.
