The Case Against IntellectualProperty
By
MICHELEBOLDRINAND DAVID LEVINE*
According to a common argument,the pres-
ence of strong intellectualpropertyrights spurs
innovation leading to higher economic growth
and increasing benefits for
all. The argument
seems coherent. No economic agent exercises
productive effort without the certainty of con-
trollingits fruits.Whatis truefor physical effort
must be true for the intellectual one: if strong
propertyrights provide good incentives for the
productionof potatoes, they must also provide
good incentives for the productionof ideas.
Why then do we argue a "case against intel-
lectual property?"Are we arguing that, while
stealing potatoes is bad, stealing ideas is good?
We are not. Economic efficiency and common
sense argue that ideas should be protected and
available for sale, just
like any
other commod-
ity. But "intellectual property" has come to
mean not only the right to own and sell ideas,
but also the right to regulate their use. This
creates a socially inefficient monopoly, and
what is commonly called intellectual property
might be better called "intellectualmonopoly."
When you buy a potato you can eat it, throw it
away, plant it, or make it into a sculpture.Cur-
rent law allows producersof CDs and books to
take this freedom away from you. When you
buy a potato you can use the "idea"of a potato
embodied in it to make better potatoes or to
invent french fries. Currentlaw allows produc-
ers of computer software or medical drugs to
take this freedom away from you. It is against
this distortedextension of intellectual property
rights that we argue.
It is a long jump from the assertion that
inventorsdeserve the fruitsof theirefforts to the
conclusion that current patent and copyright
protection are the best way of providing such
reward.Statementssuch as "A patentis the way
of rewarding somebody for coming up with a
worthy commercial idea..."'' abound in the
business, legal, and economic press. In arguing
the case against "intellectual monopoly" we
will examine this argument with care.
I. Downstream Licensing
Intellectual property has two components.
One is the right
to own and sell
ideas. The other
is the rightto controlthe use of those ideas after
sale. The first,sometimes called the rightof first
sale, we view as essential. The second, which
we referto as downstreamlicensing, we view as
economically dangerous.
All producers would
impose downstream-licensingagreementsif they
could: producersprefer not to compete against
their customers. But the absence
of competi-
tion leads to monopoly.
That the downstream-
licensing provisions of patent, copyright,
and
other private
contractslead to monopoly is
well
understood. Among economists,
the argument
has been that it is only throughmonopoly that it
is possible to rewardinventive activity. There is
a seemingly compelling logic: the cost of inno-
vation is a fixed cost, and ideas are distributedat
zero, or at least constant, marginalcost. Since
perfect competitionprices at marginalcost, the
fixed cost cannot be recouped.Consequently,if
producersof intellectual propertyare forced to
compete with their customers, they will not be
able to recoup the cost of creation.This point is
forcefully made, for example, in Paul Romer
In other work (Boldrin and Levine, 2001) we
have pointed out that creationis not a fixed, but
a sunk, cost. Since only ideas embodied in peo-
ple or productsmatter,the cost of creationis the
cost of producing the first unit. Such a "sunk
cost" is very ordinaryin economics and poses
no particular threat to perfect competition.
As far as we know there is no organizedmove-
ment to provide producersof potatoes, or any
other commodity involving sunk costs, with

property protection is associated with higher,
ratherthan lower levels of cooperationbetween
incumbentsand start-upinnovatorentrant."
Ultimately, the case against monopoly rests
less upon the welfare triangle from monopoly
pricing than upon the rent-seekingactivity
used
to get and keep
a monopoly.
In the brief exam-
ple of Section IV we show how, with govern-
ment enforced monopoly, the incentives for
rent-seeking
lead to large
welfare costs in the
production
of ideas.
III. Competition Without
Downstream Licensing
We provide an example to illustrate the
idea in Boldrin and Levine (2001) that inno-
vation can thrive in a competitive economy
even in the face of indivisibility. In this econ-
omy, individuals live forever. There are many
consumers, indexed by c < 0. In each period,
consumers either consume one unit of the
good, or not. The benefit to consumer c of
consuming a unit of the good is c - + with
q
- Consumers also prefer to consume early
rather than later: a unit of good consumed
today is worth 6 < 1 of a unit of the same
good consumed next period.
Initially, there is a single prototype of a du-
rable commoditythat generatesthe flow of con-
sumption service. The inventor or producer
owns this prototype.Once sold, no downstream
licensing is possible. At each moment of time
the prototype can either be used to generate a
flow of consumptionor be reproduced.To make
things less abstract,let us imagine that the new
good is a recordingof a new musical piece that
is embodied
in an MP3 file. Copying takes one
period,
and each MP3 that is copied produces
additional
MP3's. A technology such as
Napster increases ,B.
Under competitive conditions, in the tth pe-
riod each MP3 sells for a marketpricePt or may
be rented for one period at a rental rate rt.
Notice that consumers for whom c-+q > rt
value the song more highly than the rental cost
and will choose to listen to an MP3 that period;
consumersfor whom c
rt
will choose not
to listen to the MP3: if they have a copy, they
preferrenting
out their copy
to someone else.
In
a competitive environment,
everyone is poten-
tially a buyer and a seller.
We are interested in two questions. Is the
price of the very first copy enough to compen-
sate the producer for its sunk cost? Does the
price of the firstcopy increase or decreasewhen
new technologies increase ,B?
According to standardcompetitive theory the
sale price
of an MP3 is just the presentvalue of
the rental rates. A simple calculation2 shows
that
( 1 + ta/3-
61/t3(iI)/
)
Po=
For finite values of
po,
Po is a positive and finite
number.Since po
is what the producercan earn
from the first sale when he has no downstream
protectionat all (in practicehe should be able to
do better than this), there is money to be made
for producersof intellectual products.
Is this competitive value of intellectualprod-
ucts enough to motivate the producersto spend
the effort and time required?We do not know.
To answer this question one needs to know the
particularopportunitycost of time of the par-
ticularcreator,which clearly varies from case to
case. It seems to us, though,thatthereis no hard
empiricalevidence supportingthe view that this
value would not be enough.
We also want to understandthe social impact
of a technology that facilitates the reproduction
of "idea-goods." Does it increase or decrease
the value of intellectual productsin a competi-
tive market?Basically, received wisdom argues
that cheap copying makes it impossible for in-
novatorsto earn back their productioncosts. If,
in a competitive setting, increasing
/ lowered
po,
received wisdom would be correct:without
downstream protection, fewer "idea-goods"
would be createdas a result of the adventof the
new technology.
What does happen
to po
as / grows larger?
The answer depends on 4'.If
< 1, demandis
elastic. This is the empirically interesting
case.
As
/ grows larger, it is easy to check from the
equation above that the price of the initial copy

goes to infinity as more of it is allocated to
reproduction. In fact, this happens as ,B ap-
proaches a finite
value, but this is a special
implicationof the analytic forms we are using.
Notice that, in all cases,
the rate at which the
price falls over time is proportionalto ,B.Nev-
ertheless, with elastic demand and large (3,the
increase in the rate with which price falls over
time is associatedwith a higher initial price and
greaterrent for the innovator.
In summary, under competition and in the
empirically interesting case where demand is
elastic, improvingthe technology for reproduc-
tion increases the first sale price withoutbound.
The improvedtechnology makes it much easier
for a producerto recover sunk costs in a com-
petitive market. This does not mean that the
producerwill argue against downstreamlicens-
ing and in favor of increased competition. She
will still be able to earn more revenues with a
monopoly than under competition. However, it
is a good argument for not giving in to the
producersand grantingthem the monopoly: the
social benefit of the monopoly (the ability to
cover sunk costs and produce a socially desir-
able good) is reduced by the new technology.
This establishes competitive
marketsas a vi-
able institutionalsetting
for fostering
innovative
activity.3 We
move now to consider the viabil-
ity
of alternative
institutional settings.
IV. The Hidden Costs of Imperfect Monopoly
What happens when competitive rent is in-
sufficientto cover the cost of producingthe first
unit? Let us considerthe starkcase traditionally
consideredin economic theoryin which thereis
a fixed cost that must be recovered, and in
which the marginalcost of productionis zero.
With demand that is perfectly elastic up to an
upper bound, there is no cost of monopoly, so
this would seem the ideal environmentto im-
pose downstream-licensingrestrictions.
This is correct
only if it is not possible to
produce
similar items. In the case of textbooks,
for example,
it is easy to producebooks that are
sufficiently differentto be entitled to a separate
copyright,but sufficientlysimilaras to make no
difference to consumers. When there are many
firms competing for monopoly rents, and mar-
ket conditions are such that rents can be ob-
tained even with some degree of competition,
the rent-seeking behavior
of competing monop-
olists dissipates the social surplus by overpro-
duction of too many similar items. When we
allow for creativity in the use of markets by
having consumers submit contingent bids, then
no copyright is unambiguously better than
copyright.
Suppose in particular that firms are identi-
cal, face a fixed cost, and produce at zero
marginal cost. Suppose also that there are H
identical risk-neutral customers with fixed
reservation price who may reproduce the
good at marginal cost ( ' 0. When intellec-
tual monopoly is legally enforced through
copyright, we assume that the post-entry price
lies between the price needed to recover costs
(for each firm) and the monopoly price in a
way that depends on the number of firms and
consumers. This particular form of market
arrangement(call it "copyright-inducedcom-
petition for niches") results in what we de-
scribe as the Pareto worst outcome.
Without copyright
therewill be no outputand
no social surplusonly
if (H
< FN; otherwise,
social surplus
will be higher
than under copy-
right. This, however,
does not do justice
to the
competitive
instinct: we have excluded
the im-
portant possibility
that consumers may
submit
contingent
bids prior
to production.
In a sym-
metric equilibrium of a contingent-bidding
model, with copyright, the Pareto worst out-
come is still an equilibrium, while without
copyright, the first best is obtained.
