There seems to be a nexus of academic open knowledge efforts at Yale University. I just heard about a big Access to Knowledge conference that is happening there next month, on the 21st-23rd April.
The first goal of the Yale A2K Initiative is to come up with a new analytic framework for analysing the possibly distortive effects of public policies relying exclusively on intellectual property rights.
The speaker list looks stellar, and I am a couple of hours away from Yale right now, so I should really make an effort to get down there.
