Berkeley, January 2007
The Economics
of Monopolization
A Simple (as possible) Antitrust Analysis
Timothy F. Bresnahan
Stanford University
Slide 2
Much Recent Action in
the Courts
- Boundary with law or regulation
- Trinko (Supreme Court)
- Xerox (Federal Circuit)
- Pricing
- Spirit (6th
Circuit)
- AA (District Court)
- Bundling & c.
- LePage's (3rd
Circuit)
- Microsoft (DC
Circuit)
- Dentsply (3rd
Circuit)
|
All working on the standards
for monopolization / exclusion under § 2
Slide 3
A Rule of Reason Enquiry
- Structure is economic
- Economics enters at two
key junctures
- Market power (should
be competitive effects!)
- Causation from alleged
anticompetitive acts to changes in market power
- Much can be gained by
thinking carefully about the competitive effects and causation arguments
first
Consistent with judicial analysis in bundling cases
|
Slide 4
Difficult!
- Most exclusionary conduct
would be an ordinary and competitive business practice in some or
even most industries.
- Legal Perspective
- § 2 leads to an unstructured
rule of reason analysis
- Economic Perspective
- Monopolization leads
to a highly structured competitive effects analysis
Slide 5
Dentsply:
Economic Analysis of Monopoly Maintenance
- There is
a monopoly in prefab artificial teeth.
- There could be
competition in the market from a number of far smaller and lower priced
competitors.
- But exclusive contracts
with dealers block smaller competitors from offering consumers effective
tooth choice.
Slide 6
… Horizontal competitive
effects
- The impact of Dentsply’s
contracts is to reduce competition in the market for prefab artificial
teeth.
…Vertical restraints
logic
- Dentsply’s contracts are
with third parties, the dealers. Their economic effect is to prevent
valuable distribution contracts between the third parties and Dentsply’s
competitors.
- vs. Efficient Vertical
Contracts
Slide 7
Theory of (Anti)Competitive
Effects
More Market
Power for Defendant(s)
Exclusionary
Act
Less Market
Power for Defendant(s)

Slide 9
Much for Plaintiff
to Show
Market Power (Competitive Effects) & Causation
- There is
market power, but there could be competition…
- Usual investigation
of market power (analysis of substitution to competitors, entry
barriers) ..
- … rendered more difficult
for plaintiff by the requirement to show that a more competitive
regime could arise.
- The most direct route
for plaintiff: show that entry barriers arise from challenged
acts
- Bulk up this enquiry of
causation
- Why do third parties
go along with anticompetitive contracts?
- Why is use of third
parties an effective barrier?
Slide 10
Much for Plaintiff
to Show
Test vs. Efficiency Theories
- (v.1) Would the anticompetitive
acts be profitable for defendant and make business sense without diminishing
competition?
- aka the “sacrifice”
test.
- Does the act involve
a departure from ordinary business (competitive) behavior
that is costly to the firm?
- Will the firm
recoup that cost only through monopoly power?
- (v.2) (Called for by
every monopolization defendant in living memory.) Calculate how well
off is society (or are consumers) with and without the conduct.
- My theoretical colleagues’
“assume you have a can opener”
Slide 11
x v. Microsoft
3.1
US v. Microsoft (Browser Case)
Slide 12
Microsoft Monopoly
Maintenance Example
|
There is
a Windows monopoly.
|

[D]
|
|
There could
be dynamic competition for the operating system market
if Internet entrepreneurs built standards in
new markets.
|

[D]
|
|
But contracts with
distributors and with other complementors kept the Internet
entrepreneurs from getting a market test.

Slide 13
Economics of
the PC Industry Very Relevant
- Internet Entrepreneurs
were not horizontal competitors for Windows.
- Browser from Netscape,
Java from Sun not operating systems
- Industry experience
is that vertical disintegration leads to competition for the market
- Microsoft Internal
documents foreground this (rare) feature of this industry

A new competitor
"born" on Internet is Netscape Their browser is dominant with
70% usage share, allowing them to determine shich network
extensions will catch on. They are pursuing a multi-platfrom strategy
where they move the key API into the client to commoditize
the underlying operating system. They have attracted anumber
of public network operators to use their platform to offer information
and directory services. We have to match and beat thier offerings
including working with MCI, newspapers, and other who are considering
thier products.
One scary possibility
being discussed by Internet fans is whether they should get together
and create something far les expensive that a PC which is powerful
enough for Web browsing. This new platform would optimize
for the datatypes on the Web Gordon Bell and other approached
Intel on this and decided Intel didn't care about a low cost device
so they started suggesting that General Magic or another operating
system with a non0Intel chip is the best solution.

Slide 16
Antitrust in
Network Industries
… is ordinary antitrust
Government’s theory of the
case: competition for the market against Windows.
Competition in the
market is rare in industries like this.
Slide 17
… the rest
of Microsoft is much like Dentsply
- Anticompetitive contracts
were with third parties, such as sellers of computers and providers
of online access.
- Prevent widespread
distribution of browser, java
- Plaintiff needed to show
lack of distribution was causal and Defendant could show (as in Dentsply)
that it was not
Slide 18
Microsoft’s
Trial Defenses
- We have no market
power
- Competition
or the imminent threat of competition from everything
(down to the electric toaster) against Windows
- Our reaction to
the browser wasn’t strategic
- No competitive
threat from the Internet entrepreneurs, the CEO “had no
idea what Netscape was doing at that time.”

States Go On
Class Action Attorneys Emerge
Slide 20
Defense Options
Argue that vertical restraints
can’t ever be anticompetitive.
Argue that vertically restricting
the existing distribution system isn’t anticompetitive because (either)
Entry barriers in
distribution are low.
Distributors could refuse exclusive contracts if they were anticompetitive.
Present affirmative efficiencies story of exclusivity (free riding?)
Argue that there is never
monopoly power.
Argue that there is no monopoly
power (no entry barriers and no efficient entrants)
Argue that competition would
not change absent exclusive contracts (causation)
Slide 21
Common Elements
in
Dentsply and Microsoft
Potential of Existing Monopoly
to Change
Dentsply, Competition
in the market for teeth
Microsoft, Competition for the operating system market
Causal Link Between Alleged
Acts and Monopoly Maintenance
Dentsply,
Exclusive contracts nakedly excluded competitor
Microsoft, Exclusive (de facto) contracts excluded browser
& java; entry barriers in operating system market would have fallen
othewise
Both changes in market power
and causal links are amenable to economic analysis
Slide 22
Easy Errors
to Make (Ignoring Economics)
- Proper Assessment of
Competitive Effects requires proof of harm to competition, not just
to competitors
- Plaintiff error: we were
harmed,
…so competition must have been harmed.
- Defendant error: they
were harmed,
…so this is case about harm to competitors, not harm to competition.
- Plaintiff: Prove market
power but not that it could go away
- Defendant: Attempt, implausibly,
to disprove market power pretrial
- Leaves economist expert
incredible
Slide 23
Lessons from
Dentsply and Microsoft
Monopolization is dependent
on highly industry specific conditions.
- Market must be capable
of having two competitive regimes.
- Economic Analysis
relevant
- Exclusionary practices
must have enough causal heft to move market to less competitive regime.
- Economic Analysis
relevant
- …monopolization cases
will be rare (≠ nonexistent).
- …enquiry will be highly
specific to industry and will turn on economic analysis of changes
in competition and of causal impact of alleged exclusionary practices
