Last lecture
Why do firms differ from one another?
1.
2.
Industry factors (strategic assets)
Firm specific factors (resources)
Today:
 Innovation as a valuable source of competitive advantage
 The free rider problem
 Patents
The ‘Analytical Engine’

First general purpose mechanical
computer

Designed by Charles Babbage in
1837

Deemed too expensive to build at
the time

100 years until general purpose
computers could be cost-effectively
built

What is innovation?
Two types of innovation:

Product innovation: the introduction of entirely new products
–

(e.g. Telephone)
Process innovation: the production of existing goods at lower cost
–
(e.g. Low cost airlines)
There is less to the distinction than would appear at first sight:


A process innovation lowers the cost of producing an existing good below the
previous level
A product innovation lowers the cost of producing a new good below some
level that was previously prohibitive
A Product Innovation
A new product has become cheap
enough to be supplied/demanded.

Costs have decreased to a level
consumers are willing to pay

(It may have been that previous
products were not desirable at
any price)
A Process Innovation
An existing product becomes
cheaper to supply.

Process innovation is simply a
continuation of product
innovation
Does Innovation Add Value to the Firm?
Innovation would seem like the best guarantee of a firm’s
competitive advantage.
 Continuous innovation -> continuous cost advantage
 Provides a source of product differentiation
 May spill over to reputation/brand
Does Innovation Add Value to the Firm?
But…on closer inspection it is likely to be costly, uncertain,
and hard to manage
 May not work technically
 If it works, is there a market?
– How elastic is demand when price falls?
 If it works and there is a market, can it be defended
against competitors?
‘Public goods’
In competitive markets, innovation and knowledge creation
are public goods
Public goods are goods such that:
1.
2.
They are not depleted the more people use them
It is difficult to prevent others using them
Production of these public goods is very often subject to
free rider problems
The free rider problem
Firm B Invest in innovation
Wait and try to copy
Firm A
Invest in innovation
Wait and try to copy

The free rider problem
A free rider problem exists.
 Little or no investment in innovation without a solution
Q: Why is this bad for society?
…Let’s consider two cases, a competitive and a monopolised
industry
Innovation in a Competitive Industry
Effects of the innovation
Costs and Prices: Down
Output: Up
Consumer Surplus: Up
Producer Surplus: Unchanged
 The innovation has added no
value to the firm!
Innovation in a Monopolised Industry
Effects of the innovation
Costs and Prices: Down
Output: Up
Consumer Surplus: Up
Producer Surplus: Up
 Firm has incentive to innovate
Innovation
We are faced with a dilemma…
On the one hand: Competitive industries provide maximum
total gain from innovation
On the other: Monopolised industries provide firms with the
much needed incentives to undertake (costly) innovation
Can we have both?
An idea to solve this problem: Patents
 Patents are government enforced temporary
monopoly power!
Violating a patent can be very costly for a firm
Apple v. Samsung
Patent war waged since 2011
– Multiple jurisdictions
– Many competing claims and counter-claims
Apple’s main claim is Samsung copied physical design and
design of menu
Apple v. Samsung
 Judges in US ruled in favour of Apple in 2012 ($1.05bn)
 Series of appeals, currently with Supreme Court
– (Oct. 2016)
 Rulings in favour of Samsung in Korea, Japan and UK
Patents may encourage innovation
…But they also bring new problems
Problems with patents
–
–
–
–
–
–
–
–
Costs of litigation
Length
Breadth
Patent races
Can all ideas be patented?
Should all ideas be patented?
Ethical issues
Patent trolls
(all to be discussed in Seminar 2)
Optimal patent length
Q:
How long should a patent last?
A:
Long enough to incentivise innovation
…but not prolong monopoly power
Optimal patent length
But, how do we determine
true costs? Usually private
information.
Profit
Patent -> Monopoly profit
Time
Imitators enter
Cost of the
innovation
Would we trust firms to
report them?
Patent races
Firm B Invest in innovation
Do not invest
Firm A
Invest in innovation
Do not invest

Can all ideas be patented?
E.g. Restaurant Industry
Menu and signature dishes are a major source of competitive advantage
But a restaurant’s menu cannot be patented!
 However, chefs around the world continue to be innovative
Why?
– Tacit knowledge
– Fast moving product line
– Relational contracts?
Should all ideas be patented?
E.g. Software industry
Innovation occurs organically without patents (open source software)
Software innovations are strongly complementary with other innovations
– Restricting diffusion may limit innovation elsewhere
Software patents often broad and abstract, vagueness can lead to ‘patent
wars’ and costly litigation
Other solutions to secure innovations
Company secrecy
– (e.g. Coca-Cola)
Resources which allow firms to bring an innovation to market
quicker than competitors
– (e.g. superior sales force)
