The Economic Theory of Property
We understand physical property rights well. Economists have already studied how ownership
of physical things (like land, buildings, or objects) works, and the basic principles are pretty
clear. These ideas help us understand intellectual property too—but we have
to adjust them a bit. These same principles can be used to understand intellectual
property (like inventions, songs, or logos), but they don’t transfer perfectly.
There's a risk of disconnecting the two. As people study intellectual property more deeply,
they sometimes forget how closely it's related to physical property. That’s a problem because
lessons from physical property can still be useful.
A common oversimplification: "Incentive vs. Access."
Many economists boil the issue of intellectual property down to this tradeoff:
Incentive: Creators need motivation (like the promise of legal protection) to create
things.
Access: But giving too much protection makes it harder for others to access or use
those creations.
For example: If I invent a drug and no one else can copy it, I’ll be motivated to invent.
But that also means people who need the drug may not afford it.
But this is too simple. The real picture is more complex. Just focusing on “incentive vs. access”
leaves out big areas of law (like trademarks) and ignores how intellectual and physical
property share a deep legal and economic foundation.
What is a property right ? It’s the power to legally stop others from using something without
needing a contract.
Example: If you own a field, you can stop others from using it without having to make
deals with every passerby. And if someone wants to use your field exclusively, they
have to buy or rent it from you.
You also have the right to transfer your ownership (sell or give it away).
Benefits
There are two major types of economic benefits that come from having property rights — both
in physical property (like land) and intellectual property (like inventions, books, or
trademarks):
📌 1. Static Benefit: Preventing Overuse (The “Tragedy of the Commons”)
Imagine a natural pasture that no one owns.
If anyone can use it, it will be overgrazed — everyone brings their cattle, but no one
takes responsibility for the damage.
This is a classic case of the "tragedy of the commons": individuals act in their own
interest, which ends up hurting everyone.
📖 Real-world example:
In England, the enclosure movement turned shared pastures into private property.
It’s often criticized for being unfair, but it dramatically increased agricultural
productivity, not only by reducing overgrazing but by cutting transaction costs (e.g., not
needing permission from every user to change land use).
🔁 Parallel to intellectual property:
1
, The intellectual public domain (ideas, knowledge, works not protected by IP laws) is like
the common pasture.
Critics of IP expansion say making more things private (like more patents, copyrights,
etc.) restricts access to ideas — similar to how enclosures restricted access to land.
BUT: we can’t assume that turning all ideas into private property will always be as
beneficial as enclosing land was — it might actually block innovation and access.
📌 2. Dynamic Benefit: Incentive to Invest and Innovate
If you own a resource, you're more likely to invest in it, because you know you'll benefit
later — others can’t just take your harvest.
The dynamic benefit of a property right is the incentive that possession of such a right
imparts to invest in the creation or improvement of a resource in period 1 (for example,
planting a crop), given that no one else can appropriate the resource in period 2 (harvest
time)
In IP: a company is more likely to develop new products if competitors can’t copy and
sell the same thing without paying the R&D costs.
Without protection, competitors would just duplicate the product and sell it at the same
marginal cost, pushing the price down — the inventor wouldn’t recover their costs.
This is the traditional economic justification for IP: it rewards innovation.
⚠️
But There Are Limitations:
1. IP isn’t like physical property.
o Ideas aren’t “used up” when more people access them — they are non-rivalrous.
This is why IP is called a "public good": one person’s use doesn’t stop others
from using it too.
2. Still, overuse can occur in a different sense.
o For example: if too many trademarks exist, it becomes hard to create new
brands without legal conflicts.
o So even though ideas don’t wear out, congestion can still happen in economic or
legal terms.
3. The term “public good” is misleading.
o It sounds like something the government provides (like national defense). But
many public goods — like IP — are excludable: you can charge money for access
(e.g., software behind a paywall).
📌 3. When Property Rights Aren’t Worth It
Property rights aren’t always needed or beneficial:
When transaction costs (the effort to make and enforce contracts) are low, private
contracts may be enough. (cf. Ronald Coase theory: analysis of transaction costs /
social cost)
If something has no scarcity or no market value, ownership rights might not make
sense.
If enforcing the property right costs more than its value, it’s not worth it.
If appropriating the resource is already very hard (e.g., it’s practically impossible to
steal), property rights aren’t adding value.
➡️ These insights suggest that “depropertizing” intellectual property — allowing free access
— is sometimes the better economic choice.
Real-Life Example: Judicial Decisions
Court rulings are not copyrighted, they are in the public domain and thus a “commons”
available for all to use without a license
Why?
o They're a byproduct of the legal system.
o More court rulings wouldn’t necessarily be better rulings.
o If judges were paid per use of their opinions, yes, they might improve — but also
produce too many, increasing legal confusion and research costs.
2
, o Licensing court rulings would involve massive transaction costs for all users
(lawyers, judges, academics, etc.).
o So: keeping them public is more efficient.
Costs
This part of the text explores three main economic costs of establishing and
enforcing property rights, with special attention to how these apply differently — and often
more problematically — to intellectual property (IP). The core argument is that while property
rights offer benefits (like incentivizing innovation), they aren’t free: they bring economic
burdens that can, in many cases, outweigh their advantages.
Let’s go step by step.
📌 1. Transaction Costs: When Transferring or Reallocating Property Rights Becomes Too
Costly
A. What Are Transaction Costs?
Transaction costs are all the frictions in a market: the costs of negotiating, enforcing,
and transferring ownership rights.
These include costs for:
o Negotiating deals, Gathering information, Hiring lawyers, Coordinating among
multiple parties, Legally transferring rights,..
B. Example from Physical Property:
Suppose a factory is legally given the right to pollute a river because initially, this is
considered more valuable than recreational use. Over time, society values clean rivers
more (e.g., for tourism or public health). To reallocate the river to recreational users,
they would have to buy the rights from the factory.
But if there are many recreational users, coordinating a purchase becomes very
expensive (high transaction costs).
Result: The property right prevents efficient change.
👉 Better solution? A liability rule: let the factory keep polluting but make it pay damages to
those harmed. This realigns incentives without requiring difficult negotiations.
C. In the Context of Intellectual Property:
Transaction costs are often even higher for IP than for physical goods — and here’s
why:
❗Challenges in IP Transactions:
1. Non-physical nature:
o IP doesn’t exist in a fixed location like land — it’s intangible, hard to define
clearly, and hard to track.
2. Copying and derivation problems:
o A painting can be copied and printed on mugs, shirts, calendars. Is a similar-
looking painting a copy or independent creation? This can be hard to judge
legally.
3. Divisibility of rights:
o IP rights can be divided into tiny pieces (e.g., performance rights, display rights,
adaptation rights) — each with its own rules and owners.
🧠 So when you try to license or buy IP, it’s unclear what exactly you’re buying, and from
whom, and whether it includes all uses — this creates huge transaction costs.
📌 2. Rent-Seeking: Competing for Rights for Profit, Not Productivity
A. What is Rent-Seeking?
Economic rent is the extra income you get beyond what’s needed to incentivize your
effort or investment.
Rent-seeking is when people spend resources (money, time, legal fees) to gain these
monopoly privileges, rather than to create new value.
Example:
3
, There’s a shipwreck worth $1 million in gold. Recovering it costs $100K. Potential profit
= $900K.
If many salvagers compete to claim it, they collectively spend more than the gold is
worth (on lawyers, equipment, speed races, etc.) → social waste.
B. IP’s Version: Patent Races
Many companies race to be the first to patent an idea or invention, not because they
want to use it productively, but to lock others out and collect monopoly profits.
These races duplicate effort, over-invest in research, and often deliver less net social
benefit than the total resources spent.
📘 George Stigler (economist): warned that patent monopolies cause firms to over-invest to
secure legal exclusivity, and in the end, the return is no better than if there had been
competitive, shared innovation.
📌 3. Enforcement and Protection Costs: Guarding Property Rights Isn’t Free
A. Physical Property Protection Costs:
Think of:
o Fences, gates, toll booths — to block access
o Courts, police, lawyers — to enforce rights
o Registries — to record who owns what
These tools and services cost money — sometimes more than the benefit they provide.
Example:
A shopping center might not charge for parking, even though it could, because the cost
of collecting fees (machines, staff, lost customers) would exceed the gains.
B. Why IP Is Much Harder (and Costlier) to Protect:
❗ Key Issues:
1. IP is invisible and intangible:
o You can’t “fence in” an idea the way you can with land.
2. It’s difficult to detect theft / unauthorized uses:
o If someone steals your car, you know it — you can’t drive it anymore.
If someone copies your software or poem, you might never know, because the
reproduction does not deprive him of the use of his work but only of the exclusive
use of it. Moreover, this reproduction may take place in another state or country.
3. Copying doesn’t remove the original:
o So there’s no immediate loss — only loss of exclusive use, which is harder to
measure and detect.
4. Infringement can happen globally:
o A copy of your song might be sold online in another country — enforcing rights
across borders is legally complex and costly.
📌 4. Crowding, Waste, and the Price of Exclusion in IP
In physical property:
Limiting use (e.g., via fences) makes sense — additional users can create congestion or
wear and tear.
Example: a parking lot has limited space. Charging for it helps manage demand.
Enforcing property rights (for example, through a fence or by charging a price) not only
involves direct costs but can also reduce output by restricting use.
For example, if a shopping center charges for parking, the parking lot will be used less than if
it were free. This can be inefficient on quiet days, since additional users would impose no
extra cost but may still be deterred by the price. On busy days, however, charging a price can
