The Peculiar Economics of
Scientific Information

Traditional Goods
• With automobiles or
shoes, you have to
make a new item for
each user.
• Average cost is close
to marginal cost, with
some lumpiness for
factory size.
Traditional goods---allocation
and efficiency
How much to produce?
– Competitive solution: supply equals demand.
Who gets the output?
– Those who are willing to pay price
How are sellers induced to produce?
– Equilibrium price covers their costs.
Outcome is approximately efficient.
Information goods
• Scientific information,
once produced, can be
extended almost
costlessly to any
number of people.
• With electronic
technology, cost of
adding marginal user
is almost zero.
Cost structure for publications
• First copy cost
– Composing text and/or collecting data
– Editing and refereeing
– Type-setting
For paper journals about $100 per page
• Marginal cost per additional user
– Paper publishing---printing, handling, postage
– Electronic publishing---almost zero
– For paper journals about $.01 per page per user.

Information Goods Dilemma
• Since the social cost of allowing access to
additional user is zero, efficiency suggests
free access.
• But if access is free, how are suppliers
repaid for bearing first-copy cost?
Allocation Decisions
• For information goods, as for manufactured
goods decisions must be made about:
• How much and what to produce?
• Who gets the output?
• How to get sellers to produce desired
amounts?
Common Institutions for
Scientific Information

•
•
•
“Non-profit” Professional Societies
University Presses
For-profit publishers
Government agencies
Non-profit publishers
• Professional Societies societies publish journals,
books, data sets
• Usually charge subscriptions to libraries and
individuals to cover their costs.
– Some make a profit from their journal subscriptions and
use it for other activities
• Example: Science AAAS
• University presses, non-profit, enhance prestige of
university
For profit publishers
• Commercial publishers own journals,
charge subscriptions to libraries and
individuals in order to make profits.
• Since they own the copyrights to the articles
in their journal, they have a monopoly on
these articles.
• Prices are usually much higher than nonprofit journal prices.

Advantages of Professional
Society Journals
• Societies lend prestige and attract top
authors
• Society journals are non-profit and usually
very cheap
• Society journals maintain very high quality
standards.
Disdvantages of Professional
Society Journals
• Societies tend to be conservative. Often
slow to adopt new ideas.
• Often controlled by an aging elite.
• Little incentive for officers of society to
invest effort.
• Too slow to expand into new fields.
New Economic Journals
• In 1960 there were 30 economics journals, all
non-profit, all cheap.
• In 1980, 120 economics journals, half forprofit, half non-profit.
• In 2000, 300 economics journals, 2/3 forprofit.
• Between 1985 and 2000, top ten for-profits
almost doubled their pages, top ten nonprofits increased 20%.
Entrepreneurship
• In the 1970’s economics profession was
growing rapidly. Society journals expanded
slowly.
• Specialized field journals were rare.
• North-Holland (and other companies now
merged into Elsevier) started about 30 new
journals.
• About 12 of these could now be called leading
field journals.
Disadvantages of Commercial
journals
• High prices to libraries mean access
only for the wealthiest.
• Scientists do the work. Publishers
collect the money.
• Great inefficiency in restricting access
to science when marginal cost of access
is zero.
What about tax-supported
government provision?
• Government could pay for scientific
publication without charge to users.
• But the answer is not so simple.
• There remain some
Tough
Questions
• How much to publish?
• When to start new
journals?
• How to decentralize
and avoid fiefdoms?
• How to control quality
without stifling
innovation?
