Professor Maskin, I've gone through your written submission a couple of times. Something that I'm not seeing, and it may be a subtle difference, is the difference between what you call majority rule and alternative voting. You note that majority rule deals with five of the five problems; alternative voting deals with only four of the five.
I'm trying to figure out how nuanced the differences are. Is it a mathematical calculation? Ultimately what I'd like to hear from you is how important the shift is overall from the first past the post system we currently have to something else within a majoritarian system, as opposed to making a dramatic shift into something like proportional representation.
There are three pieces there.
