Scarcity  Competition  Discrimination
Property rights are a set of rules
which serves to allocate scarce goods
among the competitors.
No scarcity  Property Rights need not exist.

As property rights should only be applied on
scarce goods, free goods like air, seawater, in
general cases, are not considered with property
rights.
Two kinds of Property Rights
Private Property Rights
1) the exclusive right to use;
2) the exclusive right to income;
3) the right to transfer.
Common Property Rights
A good is a common property if
there is no delimitation or
delineation of its use rights to any party.
Private Property Rights
Houses
Example 1~
Private property
The owner can
- exclude others from
using it or getting into
the house.
- capture income from
renting it out
- freely transfer it to
others by selling it.
Common Property Rights
Beaches~
No one has the right to exclude
others from using it and everyone
is free to compete for its use.
Dissipation of rent
An economic proposition which
asserts that the potential rent is not
captured in which private property
rights are absent or attenuated.

Case 2
Public Basketball court
Transaction cost is increased
No one has the right to exclude others from using it.
Everyone is free to compete for its use.
People form groups and take turns to have it used, thus sometimes queues
are formed and time cost is increased for the consumers.
Case 3
Basketball court in a gymnasium
Consumer who has booked it has the exclusive
right to use it over a period of time, queues are
not formed and the time for waiting can be used
to do something more meaningful.
Case 4
Public toilets
over-exploitation lowering its value
- Everyone is free to use it. They are
always dirtier than private toilets
and the tissue paper and water are
used inefficiently. $

Intellectual Property
Intellectual property refers to creations of the mind:
inventions, literary and artistic works, and symbols,
names, images, and designs used in commerce.
Intellectual property is divided into two categories
Industrial property
nventions (patents), trademarks, industrial
esigns, and geographic indications of source
Copyright
literary and artistic works such
as novels, poems and plays,
films, musical works, artistic
works
Someone said
“If private intellectual property rights are
enforced badly, creation will no longer exist.”

好似圖書館,籃球場同埋洗手間咁。

其實呢d設施對於學校 o黎講
可以話係…但又可以話唔係
係private property,因為學校有權
