Re: Institutional Journal Costs in an Open Access Environment
Bill's revised figures don't change the conclusions I explained
in my post of April 27.
It remains true that a Spring Open Choice model ($3,000 per
article author fee) , if adopted across all of the journals Bill
studied, would result in substantial savings for all of the
institutions, including the large research university. That
institution (University of Michigan) would only pay more under an
open access model if authors' fees exceeded $3,363 (assuming no
authors fees were paid from grant funds). It is true that
research universities will pay more than non-research
universities under an author pays model (as they do now), but
(judging from Bill's data) it's not necessarily true that they
will pay more than they currently do under a subscription or
licensing model. That depends on the size of the authors' fees
-- and also the extent to which authors' fees can be supported by
grant funds.

Good afternoon.
I have discovered and corrected a methodological error in my
study that has some bearing on the results. I've posted the
corrected paper -- the version that will appear in JASIST -- at
<http://www.library.millersville.edu/public_html/walters/
journal_costs.pdf>
The correction affects the total system-wide revenue estimates
as well as the results for the Equal-Revenue Model -- the model
in which total Open Access revenue (from all institutions
combined) is held equal to total subscription revenue under the
current system.
My original paper ensured that the Equal-Revenue assumption
held true *for my sample* -- a stratified random sample that
includes two or three institutions from each U.S. News & World
Report category (Doctoral Universities, Master's Universities,
etc.).
The problem with the old version of the paper is that the the
sample does not reflect the true distribution of colleges and
universities among the various institutional categories. The
sample includes three doctoral institutions and two master's
institutions, for example, although there are actually more
than twice as many Master's Universities as Doctoral
Universities. The aggregate revenue estimates must therefore be
adjusted to account for the actual number of institutions
within each category. (The new, adjusted, revenue estimates
are presented in Table 4 and described on pages 11 and 12.)
In the old version of the paper I relied strictly on the sample
data, underestimating the relative number of small colleges --
institutions with low publishing productivity. I therefore
overestimated the total (systemwide) PLoS-Model revenue and
consequently underestimated the amount that would need to be
paid by the research universities in order to "make up the
difference."
My general conclusions are not affected by this correction, and
the abstract for the paper remains the same as before. There
are substantial changes in the quantitative results, however.
Specifically, I now estimate that within the four disciplines
included in the study,
-- the PLoS Model brings in only 15% as much revenue as the
Conventional Model -- not 28%, as reported earlier
-- a switch from the current pricing model to the Equal-Revenue
Model would increase the University of Michigan's costs by 237%
-- not 83%, as reported earlier
-- in general, institutions larger than Brandeis (about 1.1
million volumes) can expect to pay more under the Equal-Revenue
Model -- not institutions with more than 3.9 million volumes,
as reported earlier.
As several people have mentioned, these results are valid only
if we assume that all Open Access journals charge publication
fees, and that academic institutions are responsible for paying
those fees (with tuition money, grant money, government
funding, or some other source of income).
These corrections do not alter the main conclusion of the paper
-- that the wholesale implementation of either Open Access
model would reduce costs for the vast majority of institutions
while dramatically increasing the proportion of the total
system-wide cost paid by the major research universities.
