Re: Springer Open Choice uptake affects 2011 journal pricing

[Mike Rossner <rossner@mail.rockefeller.edu>]

Are there any data indicating that librarians have canceled 
subscriptions to journals
offering an open access option, specifically because a certain 
fraction of the articles
are available to the public immediately after publication?

The presumed linearity of the relationship between subscription
price and OA uptake is problematic.

Suppose the subscription price is $1500 and the OA fee $3000 per
article. If an uptake of 10 articles coincides with the
cancellation of 20 subscriptions, the net income difference for
the publisher is nil (ignoring agents fees and discounts). So why
would it then be justified to expect a reduction in subscription
price?
