I am incredibly lucky. Last August, I spent three days straight thinking almost exclusively about one topic: prediction markets, mostly algorithms. Even better, I was in great company: eleven incredible visitors from across the country took time out of their busy schedules to join me at Yahoo! Research NYC in an impromptu “prediction market powwow”: Yiling Chen, Sanmay Das, Lance Fortnow, Nicolas Lambert, Abe Othman, Mike Ruberry, Rahul Sami, Florian Teschner, Jenn Wortman Vaughn, Christof Weinhardt, and Lirong Xia. (Plus fellow Yahoos Miro Dudik, Sebastien Lahaie, and David Rothschild.) It’s amazing to have a job that allows this kind of time for research and blue-sky thinking: thanks Yahoo!. It’s humbling to have such stellar colleagues to work with: thanks everyone who came. It’s also wonderful to see “the kids” (former interns and postdocs) doing so well: Rahul now has tenure at U Michigan, Yiling is a professor at Harvard, Jenn is a professor at UCLA, and Nicolas is a professor at Stanford. (Lirong: You’re next!)
