Stuart Lawson et al. have self-archived "Opening the Black Box of Scholarly Communication Funding: A Public Data Infrastructure for Financial Flows in Academic Publishing."
Here's an excerpt:
In this paper we present work to trace and reassemble a picture of financial flows around the publication of journals in the UK in the midst of a national shift towards open access. We contend that the current lack of financial transparency around scholarly communication is an obstacle to evidence-based policy-making—leaving researchers, decision-makers and institutions in the dark about the systemic implications of new financial models. We conclude that obtaining a more joined up picture of financial flows is vital as a means for researchers, institutions and others to understand and shape changes to the sociotechnical systems that underpin scholarly communication.
