This is more of a personal update than anything else, because I posted a lot of comments questioning whether Bernie Sanders was actually going to speak at this conference---the conference program did not list him as a speaker.
The conference agenda (same URL as before) has been updated, and it now has him giving a talk between 16:00 and 16:10 titled, “The Urgency of a Moral Economy: Reflections on the 25th Anniversary of Centesimus Annus”
Thanks to Kossacks Greg Dworkin and Laurence Lewis for pointing out this update in a recent discussion thread.
Strategically, this is important because if he wasn’t actually speaking, it would have contradicted statements the Sanders campaign made to the press.
