. "[Q:] When we spoke in 0000, you said you expected OA to be a cheaper way of publishing research. Is that still your view? [A:] There are good reasons to think that OA publishing costs less, and will continue to cost less, than TA publishing at the same level of quality....However, there are also those who dispute the conclusion, generally without evidence or with misleading evidence, such as the experience of behemoth publishers with legacy overhead from the age of print and subscriptions. I'm happy to leave it an empirical question and wait for more decisive data to emerge. But my hypothesis based on present evidence is that OA publishing will cost less."
