Prospect theory is a very simple, but reasonably predictive, model of actual human decisions. This Sunday, I'll give a short presentation on prospect theory -- in particular, what kinds of predictions it makes, what ways agents using it exhibit irrational behavior, and what we can do with this knowledge. Probably, I'll ramble about some other bits of behavioral economics, too. :)
Also, of course: general discussion, and probably some board games.
This Sunday, we'll meet at David's place. If you're in town, or near it, but you don't have an easy way to get to David's place, then ask for a ride, either here or on the mailing list. Someone will surely offer; if no one else does, I will pick you up. :)
Also, also: if you're near Madison, do join our mailing list! There's some discussion there that never quite reaches this forum.
