2. BACKGROUND
The theory of public goods was first developed and
debated by the continental public finance
economists, notably Ugo Mazzola, Knut Wicksell,
Erik Lindahl, Emil Sax and others. However, the
theory of public goods stayed in its infancy until the
1950's. Modern public goods theory can be
attributed to Paul A. Samuelson.
Following Samuelson, other important contributions
to the public goods theory were by R.A.Musgrave
and J.M Buchanan. Their contributions were the
cornerstones of the modern public goods theory.
3. DEFINITION
Samuelson's definition gives two characteristics of
public goods: Indivisibility ("...can not be parcelled out
among different individuals") and Joint Consumption
("all enjoy in common."). The result of those two
characteristics is that once a public good, in
Samuelson's terminology "collective consumption
good" is produced, any given unit of the good can be
made equally available to all. According to the definition
of Samuelson, extention of the supply to one individual
facilitates its extention to all. In other words, supply of a
given unit to one individual, and supply of the same unit
to other individuals are clearly joint products.
4. The goods can be classified mainly into
two groups
Pure goods and impure goods . A pure public
good, what Samuelson calls "collective consumption
good" has mainly two characteristics: Indivisibility
and non-exclusion. Indivisibility refers to the utility of
a good which can not be parcelled out among
different individuals.
Since a pure public good is consumed collectively, it
is impossible to exclude some individuals to benefit
them. For example, exclusion is infeasible for such
goods as air pollution control, street lighting,
national defense, broadcasting TV, law and order
etc.
5. Pure Public Good
Professor James M. Buchanan, in his classic book
on public goods gives the orthodox definition of a
pure public good.
According to the orthodox analysis of public goods,
the polar case of a pure public good is pure private
good which is defined as "divisable" and
"excludable.”
A pure public good has some other characteristics
that a pure private good usually has not. These are:
Externality,
Free rider poblem
Forced rider
6. External Economies-Free Rider-Forced Rider
External economies are defined as the consumption and/or
production activities of an economic unit which affects, the benefit/and
or cost functions of other economic units either positively or negatively
Another important characteristic of a pure public good is that a
"free rider" problem. Individuals do not need to reveal their
preferences concerning which pure public good should be provided,
since they know that even without revealing their preferences they
benefit from services.
On the other hand, a pure public good may have a "forced rider"
characteristic: The term of "forced rider" explains that the supply and
the demand for some particular public goods may be obligatory.
7. Impure Goods
Basides the polar cases of pure goods -that
is pure public and pure private -there are also
some other type of public goods. The other
type of goods under the rubric of "impure
goods".
"Club goods", "common-pool goods” and
"merit/demerit goods" are the main types of
impure public goods.
11. Main Characteristic of a Club Good
A club good is an impure public good whose
benefits are excludable, but partially nonrival. The
main characteristic of a club good are two:
1.Excludable benefits: An exclusion mechanism
could be installed at a reasonable cost.
2.Partially non -rivalness: Benefits are shared by
club members. In other words, there is no rivalness
among club members.
Club goods can be classified into two groups; quasi-
public goods and toll goods.
12. Quasi Public Good
A quasi -public good is akin to the pure
private good in the sense that it has both
divisibility and exclusion features. However, a
quasi -public good generates either positive
or negative external economies. As a matter
of fact, externalities are the distinguished
feature of a quasi -public good. Education
and health are two main examples of quasi -
public goods.
13. Toll Goods
Another type of impure public good is "toll
goods" or it can be called "exclusive club
goods". Toll goods are partially indivisible
(non-rival) goods whose benefit are shared
by club members. Exclusion mechanism
could be installed in return for a fee or a user
charge, that is "toll".
14. Common Pool Goods
Common-pool goods, on the other hand are
divisible, however exclusion is difficult or
sometimes expensive to implement. There is
no need of payment to obtain or to use this
type of goods.
Fishing in the sea or ocean, extracting
minerals from nature, hunting in wild
mountains or jungles etc, are some examples
for common pool goods.
15. Merit Goods and Demerit Goods
Merit goods and Demerit goods are another type of
public goods. The concept of merit goods or "merit
wants" was first introduced by R.A. Musgrave.
"...Merit goods may be defined as those of which,
due to imperfect knowledge, individuals would
choose to consume too little. Symmetrically,
"demerit" goods may be defined as those of which,
due to imperfect knowledge, individuals would
choose to consume too much."

25. ALTERNATIVE DELIVERY
METHODS OF PUBLIC GOODS
Public goods can be provided via many arrangements. First,
govenment itself can provide all type of goods and services.
However, markets fail to provide pure public and common pool
goods. Markets are unable to supply a pure public good-say,
national defense or judiciary-due to their characteristics of
indivisibility and non-exclusion.
Market also fails to supply common pool goods now that their
consumption is free as long as individuals can spend effort to
obtain them.
The reason why this type of goods can not be provided by
marketplace is that exclusion mechanism can be hardly
implemented or sometimes it is too expensive to implement. As a
result of this, free rider usually occurs for this type of goods and
therefore market is not interested in production.
26. Key Terms with Alternative Delivery
Methods of Goods and Services
Government production
Private pruduction

Voucher system
User charges
Voluntary organizations
Build-operate-own
Build-operate-transfer
27. Although a pure public good can only be provided by
public, a pure private good can be delivered via
numerous arrangements.
First, government itself can produce this type of goods
by establishing public economic enterprises.
Secondly, government can make a contract agreement
with a private firm to supply some private goods and
services.
Third, government can transfer the management of a
specific public service to a private firm (management
contract) or transfer both management and operation
(leasing).
