Mikael Laakso and Bo-Christer Björk have published "Anatomy Of Open Access Publishing: A Study of Longitudinal Development and Internal Structure" in BMC Medicine.
Here's an excerpt:
The primary aim of this study was to measure the volume of scientific articles published in full immediate OA journals from 2000 to 2011, while observing longitudinal internal shifts in the structure of OA publishing concerning revenue models, publisher types and relative distribution among scientific disciplines. The secondary aim was to measure the share of OA articles of all journal articles, including articles made OA by publishers with a delay and individual author-paid OA articles in subscription journals (hybrid OA), as these subsets of OA publishing have mostly been ignored in previous studies.
