Question 1

The problem with monopolies is their ability to do which of the following? (i) profiteer at the expense of consumers
(ii) price their product at a level that forces consumers to pay more than they are willing or able
(iii) restrict output below the socially efficient level of production

Accepted Answer

The answer of The problem with monopolies is their ability...

Question 2

Consider a profit-maximising monopoly pricing under the following conditions. The profit-maximising price charged for goods produced is $32. The intersection of the marginal-revenue and marginal-cost curves occurs where output is 10 units and marginal cost is $16. The socially efficient level of production is 12 units. The demand curve and marginal-cost curves are linear. What is the deadweight loss?

Accepted Answer

The answer of Consider a profit-maximising monopoly pricing under the...

Question 3

It is very rare for monopolies to arise from exclusive ownership of a resource because:

Accepted Answer

Monopolies are rare due to the fact that few firms own a resource for which there are no close substitutes. In most cases, there are alternatives to the exclusive resource, making it difficult for a single firm to achieve a dominant market position. Additionally, local markets and small economies limit the potential for monopolies to arise.

Question 4

What is the monopolist's profit under the following conditions? The profit-maximising price charged for goods produced is $16. The intersection of the marginal-revenue and marginal-cost curves occurs where output is 10 units and marginal cost is $8.

Accepted Answer

The answer of What is the monopolist's profit under the...

Question 5

The simplest way for a monopoly to arise is for a single firm to:

Accepted Answer

When a single firm owns a key resource, it can potentially control the entire supply of that resource, making it difficult for other firms to compete in the market. This can lead to the firm becoming a monopoly.

Question 6

If a monopolist sells 500 units at $20 per unit and realises an average total cost of $8 per unit, what is the monopolist's profit?

Accepted Answer

The monopolist's profit is calculated as (Price - Average Total Cost) x Quantity. Here, it is ($20 - $8) x 500 = $12 x 500 = $6000.

Question 7

A perfectly price-discriminating monopolist is able to:

Accepted Answer

A perfectly price-discriminating monopolist charges each consumer the maximum they are willing to pay, thus capturing all consumer surplus as producer surplus. This leads to an efficient allocation of resources, where the quantity produced is more consistent with the socially optimal level, and the monopolist maximizes profit.

Question 8

Consider the market for water in a small town in Western Australia. Assume that the only source of water is the underground aquifer that lies directly below the town. Wells are used to supply water to the entire town.
-According to the information provided, suppose only one resident owns all the wells in town. Which of the following statements is most likely going to be true of the market for water?

Accepted Answer

Since the resident owns all the wells, they have a monopoly over the supply of water in the town. As such, they can set the price higher than the marginal cost of producing the water in order to maximize their profit. Therefore, the price of a gallon of water is likely to exceed its marginal cost.  Option A is not necessarily true, as the seller may face some constraints on their ability to raise prices. Option B is unlikely, as a monopoly seller has no incentive to sell at marginal cost. Option D is also not necessarily true, as consumers may be willing to reduce their consumption of water if the price increases too much.

Question 9

Consider the market for water in a small town in Western Australia. Assume that the only source of water is the underground aquifer that lies directly below the town. Wells are used to supply water to the entire town.
-According to the information provided, if dozens of residents have their own wells, which of the following statements most adequately describes the behaviour of sellers of water?

Accepted Answer

If many residents have their own wells, the sellers of water will face stiff competition, which will force them to lower prices so as to compete effectively in the market. As such, the price of water will be driven to be equal to its marginal cost, since the sellers will need to cover their costs while still keeping the prices low enough to be competitive. Therefore, option B is the correct answer.

Question 10

Consider the market for water in a small town in Western Australia. Assume that the only source of water is the underground aquifer that lies directly below the town. Wells are used to supply water to the entire town.
-Refer to the information provided. Jack, the sole owner of all the wells in town, decides to move to a more suitable climate, so he sells the wells to a couple of dozen different town residents. Which of the following is likely to occur?

Accepted Answer

When Jack sold the wells to different town residents, it created competition in the market for water. With multiple sellers, buyers will have more options to purchase water, and sellers will have to lower their prices to stay competitive. This means the price of water is likely to fall (choice A). Additionally, since no one seller has control over the market, individual water sellers will not have as much pricing power as Jack had (choice B). Finally, since prices are likely to fall, town residents will likely be better off (choice C). Therefore, all of the above will occur (choice D).

Question 11

The difference in total surplus between a socially efficient level of production and a monopolist's level of production is:

Accepted Answer

The difference in total surplus between a socially efficient level of production and a monopolist's level of production is a deadweight loss, meaning it represents a loss of welfare to society. Choices A and B are incorrect as there may not always be regulatory revenues, and the difference in total surplus can be significant. Therefore, the correct answer is C, a deadweight loss.

Question 12

Monopoly pricing prevents some mutually beneficial trades from taking place. These unrealised mutually beneficial trades are:

Accepted Answer

Deadweight loss refers to the loss of economic efficiency when equilibrium is not achieved, resulting in some mutually beneficial trades not taking place (i.e. unrealised gains from trade). Monopoly pricing can lead to deadweight loss as the higher price set by the monopolist reduces the quantity of goods traded, resulting in some potential trades not taking place. Therefore, the unrealised mutually beneficial trades are a deadweight loss to society.

Question 13

Given that monopoly firms do not have to compete with other firms, the outcome in a monopoly market is best described as:

Accepted Answer

Monopoly firms have the power to set prices higher than their marginal cost, resulting in lower output and higher prices than in a perfectly competitive market. This often leads to a reduced output and allocative inefficiency, not in the best interest of society. Monopolies also have less incentive to innovate and improve their products, which can lead to a lack of consumer surplus. Therefore, the outcome in a monopoly market is not in the best interest of society. The other choices (B and C) may or may not be applicable depending on the specific industry or situation.

Question 14

An appropriate way to measure the economic inefficiency of a monopoly is the:

Accepted Answer

Deadweight loss is an appropriate way to measure the economic inefficiency of a monopoly because it represents the loss of consumer and producer surplus that occurs when a monopolist restricts output and charges a higher price than the competitive market price. This inefficiency results in a reduction of overall economic welfare and is a direct consequence of the monopolist's market power. Choices A, C, and D are not directly related to measuring economic inefficiency and do not capture the full extent of the negative effects of monopoly power on the economy.

Question 15

A government created monopoly arises when:

Accepted Answer

A government created monopoly arises when the government gives a firm the exclusive right to sell some good or service. This can be done through legislation, regulations, or licensing requirements. Government spending or encouraging competition among sellers does not necessarily lead to a monopoly.

Question 16

The socially efficient level of production occurs where the marginal-cost curve intersects which of the following curves?

Accepted Answer

The answer of The socially efficient level of production occurs...

Question 17

When the price of a good increases, which of the following happen(s) to the quantity sold for a monopoly firm? (i) customers are forced to buy at the higher price
(ii) quantity sold will stay the same
(iii) revenue will necessarily increase
(iv) quantity sold will fall

Accepted Answer

When the price of a good increases for a monopoly firm, the customers are not forced to buy at the higher price as they have no other alternatives. However, the quantity sold will fall as consumers will reduce their demand due to the higher price. As a result, revenue may or may not necessarily increase, depending on whether the increase in price compensated for the decrease in quantity sold. Therefore, only option (iv) is correct.

Question 18

For a profit-maximising monopolist, output should be increased to enhance economic wellbeing as long as:

Accepted Answer

The answer of For a profit-maximising monopolist, output should be...

Question 19

A monopoly market:

Accepted Answer

A monopoly market generally fails to maximise total economic wellbeing as it can set higher prices and restrict output, resulting in a deadweight loss and a reduced level of consumer surplus. Additionally, the lack of competition may lead to a decrease in innovation and efficiency, which can distort the allocation of resources and harm overall economic welfare.

Question 20

Which of the following scenarios best represents a monopoly situation?

Accepted Answer

A monopoly situation occurs when a single company or entity has complete control over the supply of a particular good or service. In scenario B, Bill owns the only grocery store in a small community, which means he is the sole provider of groceries in the area, making it a monopoly situation. Scenario A only involves two sellers, while scenario C involves competition between different brands of fishing equipment.
