IV.) Monopoly RegulationSummary of some of the problems of
monopolies...Rent Seeking
Though it can mean more is produced in the market, it often is seen that monopolies are taking advantage of those less fortunate
Inefficient Market Outcomes
Price Discrimination
歧视 Discrimination: treating people differently based on some characteristic, e.g. race or gender.
The characteristic used in price discrimination is willingness to pay (WTP):
A firm can increase profit by charging a higher price to buyers with higher WTP.
IV.) Monopoly Power
Price Discrimination: selling the same good at different prices to different buyers.
It is sometimes possible for a monopoly to charge different people difference prices
What can public policy do about the problems and issues that occur with monopolies?
There are three common answers…
- Public Ownership- Price Regulation and Anti- Trust Laws- Do nothing- Give them a Subsidy
IV.) Monopoly Regulation
the good is supplied by the government or by a firm owned by the government.

Some companies can do things cheaper being large and we typically
think governments can do this best (but do they?)

Airlines are often oligopolistic and not monopolies, but can act like monopolies and are
often regulated for safety and prices
The Good:
- Can prevent unfair price discrimination and monopoly profit seeking that hurts consumers and also create more output that a profit maximizing firm might not do.
IV.) Monopoly Regulationthe good is supplied by
the government or by a firm owned by the government.
- Public Ownership- Price Regulation and Anti- Trust Laws- Do nothing- Give them a Subsidy
The Good:- Can prevent unfair price discrimination and monopoly
profit seeking that hurts consumers and also create more output that a profit maximizing firm might not do. The Bad:- Often poorly run, no profit motive,
can be very inefficient and end up performing worse.
- Sometimes doing nothing is better.
IV.) Monopoly Regulation
- No desire to innovate even if they have the ability.

Public Ownership
Rent Seekingis the act of obtaining special
treatment by the government to create economic profit or to divert consumer surplus or producer surplus away from others.
Rent seeking does not always create a monopoly, but it always restricts competition and often creates a monopoly.
IV.) Monopoly and Competition
Rent Seeking behavior is just another fancy word
for Corruption
Rules that control the prices that monopolies can charge or will break them into smaller companies so they will lose their monopoly power.
Most common strategy used in the U.S.
IV.) Monopoly Regulation- Public Ownership- Price Regulation and Anti- Trust Laws- Do nothing- Give them a Subsidy
Rules that control the prices that monopolies can charge or will break them into smaller companies so they will lose their monopoly power.
The Good:- Can prevent price discrimination,
break up monopolies and benefit consumers and give them more choices.

Price Regulations and Anti-Trust Laws
Rules that control the prices that monopolies can charge or will break them into smaller companies so they will lose their monopoly power.The Good:
- Can prevent price discrimination, break up monopolies and benefit consumers and give them more choices.
The Bad:- Price controls are hard to
determine and sometimes hurt monopolies too much.
- Best answer is usually to break up the monopoly.

Problem behavior that will come up again and
again…
Two most commonly used price controls
IV.) Monopoly RegulationWith private companies selling
durable goods, it is most common to break up the company somehow.
With other private companies or even publicly owned companies that produce a service such as, utilities like water and power, price controls are usually more common.

IV.) Monopoly Regulation1. Socially optimized pricing also called Marginal cost
pricing
The Good:- It is allocatively efficient, more is
produced at a lower price for everyone.The Bad:
- The price is so low that most monopolies would go out of business, so the government would have to give them a subsidy.
- A price that would be like if it was a perfectly competitive firm

*** More then a monopoly would like to produce and less then society would like to have. Most common way to regulate a monopoly since they still get a normal profit.
A price ceiling that it is productively efficient, though not allocatively efficient for society and still allows the monopoly to get at least a normal profit
Fair return price
P = ATC
IV.) Monopoly Regulation
The Good:- The output is higher and the price
is lower then an unregulated monopoly.
- The firm would still get a normal profit so a subsidy is usually not needed.

regulations
IV.) Monopoly Regulation
The Good:
- It is productively efficient, the output is higher and the price is lower then an unregulated monopoly.
- The firm would still get a normal profit so a subsidy is usually not needed.The Bad:
- It may still be not enough output or low enough prices for society’s desires. Also calculating the price is very difficult and inefficient and prone 倾向于 to rent seeking.

IV.) Monopoly and Competition
By doing something, you promote more of this behavior in trying to make the new rules in your favor
IV.) Monopoly Regulation- Public Ownership- Price Regulation and Anti- Trust Laws- Do nothing- Give them a Subsidy
Monopolies usually don’t produce enough of what society wants, mostly because it is not profitable for them. One market oriented solution to get the to produce more is to make it more profitable for them.
This basically means that the government gives them money to produce more.
Examples are: water company, power company, many public goods.
IV.) Monopoly RegulationSome goods and services are considered natural monopolies
and are the best way to provide people what they desire.
In the case of the electric company, it is most desirable to produce as much as possible (allocative efficiency) and not necessarily worry about profit, even though they still must cover their costs.
1. Lump Sum Subsidies (can be a bad idea)2. Subsidies per Unit (usually a better idea)
To get the monopoly to produce more (and not price discriminate) the government will have to pay the monopoly to do so.
Two ways to do so:
IV.) Monopoly Regulation
A one time payment to the monopoly to do with as they wish.
This only affects fixed costs

The output stays the same, it’s just now that the costs are lower. To produce more what is needed is the shift the marginal cost line to the right.

So a little summary…
IV.) Monopoly Regulation
IV.) Monopoly Regulation
Price Discrimination - Good for Society as more is produced
Capturing Economies of Scale-Economies of scale can lead to natural monopoly.-It is more efficient to regulate natural monopoly than to break it up and make the industry competitive.
Strengthening the Incentives to Innovate- Monopoly might be more innovative than competition.-Innovation can create a monopoly.
Benefits of a Monopoly
IV.) Monopoly Regulation
Price Discrimination - Bad for consumers and high prices
Not efficient from a society’s perspective - Does not produce as much as people want
Loses the Incentives to Innovate -Monopoly might not innovate because it doesn’t have to.

Per unit subsidies can increase output in the market
Lump sum subsidies might not increase output in the market
That’s all for nowThanks
