Open access to 2013 work: "Open access versions of a couple of my 2013/4 publications and talks have recently been made available through the University of Edinburgh. These versions are the best possible permitted under the terms of the relevant publishers – peer reviewed but not fully formatted for (print) publication in the journal in question. They are accessible without registration or charge to all.
Earlier publications continue to be available via my SSRN page without a need for a subscription, in various forms." 'via Blog this'
