Here is an interesting paper on the economic returns of OA (from Peter Suber's blog). Arun ------ More on the Houghton/Sheehan analysis Stevan Harnad, Maximising the Return on Resource Investment in Research, August 10, 2006. Excerpt: In a recent preprint, Houghton & Sheehan (2006), using estimates from economic modeling, have confirmed the substantial potential enhancement of the return on resource investment in research if the resulting articles are made Open Access:... Excerpts: "Whether applied across the board or to sector specific research findings (e.g. open access to publicly funded research) it seems that there may be substantial potential benefits to be gained from more open access. For example [GERD = Gross Expenditure on Research and Development]... - With Germany's GERD at USD 58.7 billion and assuming social returns to R&D of 50%, a 5% increase in access and efficiency would have been worth USD 3 billion; - With Japan's GERD at USD 112.7 billion and assuming social returns to R&D of 50%, a 5% increase in access and efficiency would have been worth USD 5.8 billion; - With the United Kingdom's GERD at USD 33.7 billion and assuming social returns to R&D of 50%, a 5% increase in access and efficiency would have been worth USD 1.7 billion; and - With the United State's GERD at USD 312.5 billion and assuming social returns to R&D of 50%, a 5% increase in access and efficiency would have been worth USD 16 billion. "While it is impossible to calculate the quantum of benefits with certainty, these simple estimates of the potential impacts of enhanced access on returns to R&D suggest that a move towards more open access may have substantial positive impacts... "Given substantial R&D expenditures and the scale of the potential impacts identified in this preliminary work, these issues represent fertile ground for further policy relevant inquiry." These estimates agree substantially with prior estimates that have been made (e.g., for the UK, Canada and Australia, see below). Research Funding Councils and Universities worldwide are at last beginning to realise that it is high time (indeed well overdue) to maximise the returns on their research investment by mandating Open Access self-archiving....
