font-family:Arial'>I’m new to this list, and I was would like to ask a
question. I’ve been reading Allan Gibbard’s classic paper on
lottery voting, “Manipulation of Schemes that Mix Voting with Chance”
(<i><span style='font-style:italic'>Econometrica</span></i> 45, April 1977). The
proof of the main result is very dense and difficult, and I now find myself
stuck trying to figure it out. Is anyone familiar with the proof? If so, I’d
appreciate any help you can give me, particularly with Lemma 4. Thank you. Feel
free to contact me off-list if you prefer.<o:p></o:p></span></font></p>
