Monopoly Pricing
1
Perfectly competitive market

Firms are price takers



Price is determined by the price mechanism
If a firm raises its selling price, it will lose all of its
customers.
E.g. Market price = \$6, Quantity demanded = 80 units


In perfectly competitive market


P = \$6
Each additional unit sold, revenue = \$6
Marginal Revenue (MR) = \$6
P = MR
Marginal cost rises when output rises

MC curve is upward sloping
Perfectly competitive market

Condition of profit maximization

Total revenue &gt; Total cost



i.e. P &gt; AC
Price (Marginal revenue) = Marginal cost

i.e. P = MC

If P &gt; MC, firm can earn more profit by raising output

If P &lt; MC, firm can earn by cutting output

Suppose no fixed cost:
If there’s no externality, when
MB = MC, TSS is max.
i.e. Market efficiency
Monopoly

A single supplier in the market

No close substitution

Will not lose all the customers when it raises the price

Price searcher with monopoly powers on price and
determine its output

E.g. MTR in HK, CLP in Kowloon and N.T.

Monopoly pricing

Simple monopoly pricing

A firm set a uniform price for each unit of its output at this price, consumers
can buy as much as they want.


Market demand restricts the market power of a monopolist.

From the demand schedule: When P = \$9, Qd = 1 unit

If Firm A set the price at \$9, 1 unit will be sold only.

If Firm A want to sell 4 units, it has to lower the price to \$6.
One price-output combination based on consumers’ demand.

Price = Average Revenue (AR)

Under simple monopoly pricing:

Total revenue (TR) = P x Q

Since AR = TR  Q, then P = AR


The change in total revenue as a
result of selling an additional unit

MRn = TRn – TR(n-1)
At Q = 1 unit,

MR = P = \$9

At Q = 2 units

MR = \$7, P = \$8
 MR &lt; P
When output increases, MR falls
Hence, MR curve is downward sloping
below the AR (demand) curve

Price discrimination

Definition

A situation where seller sells identical goods produced at
the same cost to different customers at different prices.

Examples

MTR: Lower prices for children and elderly

Fast-food shop: Special offer for students

University scholarship
Reason for practising price discrimination

In simple monopoly pricing, buyers have consumer surplus.

Sellers may try to capture the consumer surplus to increase profits.


i.e. From consumer surplus to producer surplus
Price discrimination is a pricing arrangement a firm uses to
increase profit.

Price setting based on the different consumers’ demand curves.
How does price discrimination increase profit?

Given MB of a flower:

Suppose cost = \$0


If the selling price of the flower is:
Price (\$)

Total revenue (\$)

50
2
100
80


Then the profit-maximizing price is \$50 and quantity is 2 units

Consumer surplus: A: \$80 - \$50 = \$30 and B: \$50 - \$50 = \$0

Producer surplus: \$50 x 2 = \$100

Total social surplus: \$100 + \$30 = \$130


Price to A = \$80, Price to B = \$50 and Price to C = \$20
Total revenue = Producer surplus = \$80 + \$50 + \$20 = \$150
Consumer surplus: A: \$80 - \$80 = \$0, B: \$50 - \$50 = \$0 and C: \$20 - \$20 = \$0
Total social surplus = \$150 + \$0 = \$150
Total sales = 3 units

How to identify price discrimination?

Key 1: Whether the goods and their costs are the same?

Price discrimination is found if


No price discrimination if



Same product sold in different price to different customers
Quality is different
Costs are different
However, Price discrimination is found if


Difference in price is disproportionate to the different in quality or cost
E.g.
Normal Set Lunch: Soup + Curry Chicken + Tea ( \$30 )
Student Set Lunch: Curry Chicken + Tea ( \$16 )
[The bowl of soup is disproportionately expensive.]
How to identify price discrimination?

Key 2: Whether the unit prices are the same?

Example: Telecommunication Plan

Plan A: \$51 – 1100 minutes [i.e. \$0.0464 per minute]



Plan B: \$73 – 1600 minutes [i.e. \$0.0456 per minute]
Plan C: \$88 – 2100 minutes [i.e. \$0.0419 per minute]


More preferable to common users, like students, for leisure usage
More preferable to businessman for occupational needs
Who has higher price elasticity in buying
Different in price is not necessarily price discrimination

Peak hour surcharge



E.g. Minibus fare
 Higher cost in running on the road
 Higher demand
E.g. Salon before CNY
 Higher cost in hiring additional workers
 Higher demand
Special offer to privileged customers

E.g. Loan with lower interest rate
 Loyal customers: lower chance of bad debt (cost)
 With stable occupation: stable income, less possibility of late
repayment
Types of goods can price discrimination be more
easily practised

Easy to separate the consumers

Low cost of preventing resale


If consumers can resell the goods, they can buy at a
lower price and resell at a higher price, so sellers can’t
capture the consumer surplus
In general, price discrimination is more common in
services than commodities.



Immediate consumption
Hard to resell
For commodities, it’s hard for the sellers to prevent resale.
3 Types and examples of price discrimination

First degree price discrimination

Second degree price discrimination

Third degree price discrimination
Third degree price discrimination

A situation where the seller separates customers with different
price elasticity of demand into two or more groups and charges
them different prices.

Also known as market segmentation

Different elasticity suggest that

Different willingness to pay

More elastic demand, lower willingness to pay.

Less elastic demand, high willingness to pay.
Third degree price discrimination

Suppose MC of the good is constant.

When MC = MR,

PB (inelastic demand) &gt; PA (elastic demand)
Third degree price discrimination
Examples
 Discount for students and the elderly




E.g. MTR, restaurants, etc.
Less income
 Lower willingness to pay
 Higher elasticity of demand
Easy to be identified
Local and overseas market



E.g. Kindle sold in amazon.com (US\$109) and amazon.co.uk (&pound;89)
Easy to separate the market according to the price elasticity of demand
Geographical separations can effectively prevent resale
Third degree price discrimination

Profit = (\$50 - \$10) x 3000 + (\$15 - \$10) x 2000 - \$50,000 = \$80,000
 If the law requires a uniform price, books will be sold locally only.
Total revenue = (\$50 - \$10) x 3000 - \$50,000 ) = \$70,000
 Publisher will lose. Less profit.
 Overseas consumers will lose. They can’t buy the books.
 Hence, less consumer surplus.
Conclusion
 Prohibition of price discrimination will reduce the choices that producers and
consumers have. This may lead to Overall loss to society.

Second degree price discrimination

A situation where the seller charges buyers higher prices for
quantities with greater marginal benefits and lower prices for
quantities with small marginal benefits.

Not to charge according to different customers,
but different quantities.

Also known as multipart pricing.

Customers have the power to do ‘self-selection’.
Second degree price discrimination

Mutlipart pricing: sellers charges different prices for different
amounts (or blocks) of a good, with higher prices for the first few
units and lower prices for subsequent one.

Sellers do not need to separate their customers into different groups
A quantity-based pricing arrangement to the customers.
Customers will do the self-selection.


Second degree price discrimination
Examples
1. Provide discount for specified quantity


\$100 per piece  First two average \$100 per piece
Buy 3  10% discount, i.e. \$100 x 3 x 90% = \$270
Average price = \$90 per piece
2. Provide discount package





First 2 units: \$100 each  Average \$100 per piece
Third unit: \$\$70
Total: \$100 + \$100 + \$70 = \$270 Average \$90 per price
Both methods have the same effect of multipart pricing.
They are second degree price discrimination.
Second degree price discrimination
Examples
3. Two-part tariffs
inclusive of 50 tokens
Amusement Park
After entering the park, 10
 Tokens before entrance at higher price
tokens for every \$20
 Tokens after entrance at lower price
 The more tokens customers buy, the lower the average price.
Token\$100 per piece  First two average \$100 per piece
Video rental clubs
 Membership fee (fixed) + Coupons (variable)
 The more coupons customers buy, the lower the average price
First degree price discrimination

A situation where the seller charges each consumer the maximum
price who prepared to pay for each unit, which is along the
demand curve of different consumers.

Extract the consumer surplus.

i.e. Consumer surplus becomes producer surplus

Producer surplus = Total social surplus

Also known as perfect price discrimination.
First degree price discrimination

According to the buyers’ marginal benefit, the seller charges



\$9 for the 1st unit, \$8 for the 2nd unit, \$7 for the 3rd unit, \$6 for the 4th unit
\$5 for the 5th unit, where profit-maximization achieved (MC = MB)
No consumer surplus. All surplus becomes producer surplus.


Seller has to know the willingness to pay of all consumers.
Quite impossible to practise the first degree price discrimination in the reality.


Ada: 2 units, TR=\$4+\$3=\$7, average price=\$72=\$3.5, consumer surplus =\$0
(Therefore, Ada will accept a package of 2 apples at \$7.)
First degree price discrimination
Examples

First degree discrimination takes place when bartering exists

The bid and offer system in the housing market where potential
home buyers put in an offer on an individual property

Negotiating prices with dealers for second hand cars

Haggling for the price of a hotel room (mostly foreign countries)

Dutch auctions

The sellers begins with a high asking price for an item. If nobody responds to it, he lower the price, until
the item to be sold to the first person who accept the price.
Differences among 3 types of price discrimination
1. First degree vs. Second degree price discrimination

Whether the firm can extract the consumer surplus from each consumer
complete.

First degree: Complete extraction. Different price for each unit.

Second degree: Multipart pricing, consumer surplus still found.
2. Second degree vs. Third degree price discrimination

Whether market segmentation exists.

Third degree: Different groups face different price arrangement.

Second degree: Consumers can choose different price arrangement according
to their willingness to pay, but the firm may not know which groups do they
belong to and how much they are willing to pay.
Other examples of price discrimination
1. Coupon clipping


Customers can have lower price by using coupon.
The firm does not cut the price because


Customers with higher elasticity of demand and lower willingness to pay will
try hard to use the coupon.
The customers separate themselves into different groups.
2. Medical fees



Cost of providing the treatment of same illness to the rich and the poor is
the same.
Rich people: higher income, higher willingness to pay
Poor people: lower willingness to pay
Other examples of price discrimination
3. Air ticket


Different prices for tickets



Passengers for leisure



lower elasticity, higher price
don’t want to stay over the weekend
Higher price elasticity, lower price
Don’t‘ mind staying over the weekend, so lower price for ticket for travellers to
stay for the weekend.
However, different prices of first class, business class and economy class
may not be price discrimination because of different costs for providing
services
Conditions for price discrimination
General conditions
1.
Monopoly or market power


2.
Can effectively prevent resale

3.
If consumers can resell the products easily, buy low sell high. Take away the firm’s
customers who are willing to pay higher prices.
Consumers’ willingness to pay is different

4.
The firm can influence the market price by changing its output.
Price search, facing a downward sloping demand curve.
If no difference, products will be sold in the same price.
Low cost is practising price discrimination


Price discrimination involves complicated pricing arrangement.
If cost is too higher, simple monopoly pricing will be better than price
discrimination
Conditions for price discrimination
Specific conditions
For first degree price discrimination
 Aim at extracting all consumer surplus
 Seller must have perfect information on each customer’s willingness to pay.
For third degree price discrimination
 Aim at put different consumers into different group according to their elasticity
of demand.
 Consumers’ price elasticity of demand must be different.
For second degree price discrimination
 No need to have perfect information on consumers’ willingness to pay. (1st)
 No need to group consumers according to their price elasticity of demand. (3rd)
 Need to have a general idea about consumers’ preferences or consumption
patterns before making different price arrangement
Conditions for price discrimination
Consumers’ market information and price discrimination
In tradition economics, for third degree price discrimination
 Different price elasticity of demand of consumer is necessary.
Argument from Steven N.S.Cheung
 Not necessarily have different price elasticity of demand
 Different information cost can help price discrimination to be practised


Consumers have different information about the market
E.g.
 Tourists and local residents might have the same elasticity of demand on camera.
 However, tourists have less information, i.e. higher information cost, and would
likely to pay higher than local residents.
Monopoly and anti-competition
In traditional economics, ‘Monopoly’ is often labelled as

anti-competitive

harmful to the interest of consumers and society
However, economists argue that

monopoly may be anti-competitive,

but might not be harmful to the society.
Monopoly and anti-competition
1. Is monopoly necessarily anti-competitive?


No, the reasons are:

Monopoly because of economies of scale

Elimination of weak competitors under normal market competition.
Not necessarily anti-competitive, but beneficial to the society

Natural monopoly  lower average cost, so lower price

Dominate the market because of high quality, e.g. MS Windows XP in 2001
Monopoly and anti-competition
2. Why is monopoly often seen as being anti-competitive and harmful?


Monopolists, who’s dominate the market, aimed at more profit

have the ability and

Different types of anti-competitive practice
Anti-competitive practices refer to all behaviours that distort or restrict
market competition.
4 Types of anti-competitive practices

Mergers (合併)

Horizontal agreement (橫向協議) [also known as ‘Cartel’]


Vertical agreement (縱向協議)


Competitors in the same industry make agreement on price and output in order to
jointly control the market price.
Agreement on purchasing or sales conditions made between firms in different stages in
production (producers) or sales chain (distributors)
Abuse of dominance (縱向協議)

Aim at reduce competition

Increase the power of the newly merged enterprise in controlling the price

Examples: Toyota and Lexus (motor vehicle), HP and compaq (computer)

Guideline in US case:

Large horizontal mergers are often perceived as anticompetitive.

If one company holding 20% of the market share combines with another company also holding 20% of the
market share, their combined share holding will then increase to 40%.

This large horizontal merger has now given the new company an unfair market advantage over its competitors.

The amalgamation of Daimler-Benz and Chrysler is a popular example of a horizontal merger.
Mergers
2. Potential competition mergers

the merging of a firm and another firm that plans to enter the market and
compete with it.

Justification and concerns for competition policy
The Hong Kong SAR Government set up Competition Policy Review
Committee (CPRC) in June 2005.

Review the policy and law overseas

Propose competition policy and law for legislation
Justification and concerns for competition policy
Major justification

To provide a legal basis for the investigation and sanctioning of anticompetitive conduct

To strengthen the competition regulatory framework in order to promote market
discipline.

To improve the business environment and provide a level playing-field for

To improve transparency through delineating what constitutes anti-competitive
conduct so that firms and the public are fully aware of them and can prevent
their occurrence in society.

Without such regulation through legislation, in the long run there might be an
adverse effect on the relative competitiveness of HK, especially in those sectors
with high entry barriers.
Justification and concerns for competition policy
Concerns
1. Does HK need a competition policy?

Interference with the market structure


Increase in the cost of doing business



Harmful to the famous free and competitive market in HK?
Higher cost of production  Lower HK’s regional competitiveness
Effects on the development of small- and medium-size enterprises (SMEs)

SMEs may not fully understand their responsibilities under the new law  Easy to break the law

SMEs may have high legal fee

SMEs may under the threat of facing a lot of lawsuits. Large enterprises may make use of the law
to kick out SMEs.
Use of alternative ways to enhance market competition

Legislation should be the last option. Any other better ways to achieve the target?
Justification and concerns for competition policy
Concerns
2. Should it be a cross-sector or a sector-specific competition law?

Existing sector-specific anti-competition provision could not stop cross-sector
anti-competitive practices

The property management company bundled management fee with telecommunication service
charge

However, Telecommunication Ordinance does not regulate the practices of property management
companies.

Anti-competitive practices can be found in different sectors.

Legislation to tackle cross-sector bundling effectively and avoid discrimination
against certain business sectors and consumers.
Justification and concerns for competition policy
Concerns
3. What scope of behaviour should be covered by the competition law?

The new law should not point against market structures or natural monopolies.

Focus on stopping specific anti-competitive practices that hinder economic
efficiency or free trade and are not in the interest of consumers.

The CPRC recommended 7 types of anti-competitive practices to be covered in
the new law

Price-fixing

Bid rigging

Market division

Sales and production quotas

Joint boycotts

Unfair and discriminatory standards

Abuse of dominance
However, the CPRC added that these
practices are not illegal unless they are
found:
1. To have been carried out with the
intent to distort the market; or
2. To have the effect of distorting normal
market operation and lessening
competition
Justification and concerns for competition policy
Concerns
4. Should there be exclusions or exemptions?

The new law is aimed at avoid anti-competitive practices in business sectors.

Government should be exempted from being sued under the new law.

Since the new law may be abused to suppress lawful competitive business
activities, the CPRC also suggested that the regulatory authority should have the
discretion to ignore complaints that are inappropriate.
5. Should it be a civil or criminal offence?

Heavy fine and disqualification from holding a directorship in a company should
be enough.

Since the law is first enacted, civil penalties are more appropriate.
