Will Wilkinson's looking for budding libertarian grad-student types to attend this summer's (free) Social Change Workshop on institutions and rationality. I attended myself back in 2002 (as did Sasha Volokh of Volokh Conspiracy fame) and can verify that it's a fascinating week. Last time around there was philosophisin' with David Schmidtz, economizin' with (Nobel laureates) James Buchanan and Doug North, and evolutionary psychologizin' with Leda Cosmides. I assume this year's roster will be similarly spiffy. You can apply here if you're interested.
