Tabarrok on Arrow

Arrow showed that when a group chooses, there are no underlying preferences to uncover--not even in theory. In one sense, the theorem is trivial. We know or should always have known that a group doesn't have preferences anymore than a group smiles. What Arrow showed, however, is that without invoking special cases we can't even rationalize group choices as if leviathan had preferences. Put differently, the only leviathan that rationalizes group choice has the preferences of a madman.

I gave an e-interview to Mike Lee a while back for his website, GGGOZU.COM. His photographer turned up shortly before the Elevenses at Three at McNally-Jackson. The whole thing here.

elevenses at 3

Sara Ortiz of McNally Jackson Books has very kindly offered to let me turn up there and see if anyone else turns up. Had been thinking of something along the lines of brunch but it looks as though the afternoon of Saturday the 9th works better (it's understood in civilised society, of course, that a matinée takes place in the afternoon), so:

I'll be turning up at the café at McN J at 3pm on Saturday Oct 9, and if anyone else wants to come it will be great to see you.

The address is
