It is by now common wisdom that our current financial crisis is due in large part to misplaced incentives in our financial system. Analysts and fund managers were rewarded for short-term thinking and risk-taking.

Can’t really complain about that. Tomorrow I get to hear mini-presentations on everyone’s research proposals, which should be very interesting. My own project will be on the long term, gradual evolution of cooperation in spatially structured populations, using a mathematical framework known as adaptive dynamics.

I’m expecting to learn a lot here, and I’ll share as much as I can with you readers. Looking forward to it!

Everyone seems to have an opinion on the future prospects of Facebook and Twitter. Some of us even feel strongly enough to want to bet on it.
