What are public goods?
Public Good

Generally, goods that:
(1) when made available can be
consumed by others at little (or
perhaps no) marginal cost (non-rival
goods or jointness of supply) and,
 (2) are non-excludable.

Tragedy of the commons (Hardin
1968)

Non-Excludability and the ‘free-rider’
problem
 Non-excludability
creates the freerider problem
 Yet,
If free-riding is
rampant the
collective good will
not be produced

Discretionary Databases as Public Good?

See: Connolly and Thorn 1990;
Markus, 1990

Information Goods are Public Goods (Kollock
1999, Shapiro and Varian 1999, Cheshire 2005)



When distributed online, it is
difficult to keep people from
benefiting from information
goods
Free-riding in such a context
may be normative behavior–
simply using the information
provided by others.
Cost of contribution is a central
to understanding the
production of information
goods
12
Economics of Information Goods

Some key features of
many information goods:

Non-rival (high jointness
of supply)

Replicability (varies; DRM
vs. non-DRM)

Low cost of production
(especially relative to use
value)
13
If we are tempted to free-ride, then why are
public information goods produced?
A single information good can
be a public good

This has a significant impact on
the production function
14
Problem of Social Loafing

Social Loafing: Phenomenon
whereby individuals exert less
effort on a collective task than
they do on a comparable
individual task.
 Across
a range of settings, people
contribute less than the optimal
amount to public goods and
consume more than their ‘fair’
share of common pool resources
(see Beenan et al 2004)
15
Social Psychological Benefits?


Some individuals are willing to
contribute to a public good even when
the costs appear to outweigh the
benefits (i.e., Coleman 1988, Piliavin
1990, Simmons 1992, etc)
 Altrusim, rational zealotry
Other motivations (Kollock 1999):
 Sense of efficacy (making an impact;
belief that we will succeed)
 Anticipation of reciprocity
 Effect on personal reputation
16
Privileged Groups
"The fact that many digital public
goods can be provided by a single
individual means that in these cases
there are no coordination costs to
bear and that there is no danger of
being a sucker, in the sense of
contributing to a good that requires
the efforts of many, only to find that
too few have contributed [...]”
-Peter Kollock

Information Goods on the Internet: The Issue
of Group Size

Generally, smaller groups tend to
have a better chance of producing
a public good (Olson 1965)

Why?
More benefits for each person
 Larger impact of any single
contribution
 Generally, lower costs of organization

18
But what about VERY LARGE groups?

Why “free-riding” is not necessarily a
bad thing (Rafaeli and Raban)
20
• It is better for the group if many
members free ride than if they
contribute negatively (poor
knowledge, unexamined sources,
etc.).
• Information sought tends to be
unique. A free-rider on a substantial
portion of exchanges may become
an active contributor in a particular
question.
20
Rafaeli and Raban (continued)
• Free-riders are virtually invisible
in online systems and tend to be
ignored. They are not perceived as
free-riders.
• Connectivity does not mean that
everyone who is connected actually
has information to contribute. Yet,
these “free-riders” get a unique
learning opportunity and can feel
part of the community, generating
community level positive effects
