The economic costs of open access

Publishers could take a big hit if the government starts requiring open access, after an embargo, to journal articles based on federal funding, David Wojick writes on the Scholarly Kitchen: "The starting point is that a great many of the downloads of journal articles occur more than 12 months after publication. Making these articles freely available has the potential to reduce the value of journals to a similar degree. Thus revenue losses of 50% or more are possible."
