I wrote about a linear programming proof of Arrow's Impossibility Theorem due to Rakesh Vohra and his collaborators in a series of posts, starting with http://deniallogic.blogspot.com/2015/04/transitivity.html and ending with a proof of Arrow's theorem in http://deniallogic.blogspot.com/2015/05/arrows-theorem.html. The point was to fill in enough details that, for me, were missing from the paper [1].
