Rakesh Vohra memorializes Herb Scarf (1930-2015) with a quote from Horace, and passes along the sad news that Scarf passed away two days ago, on November 15.
Scarf was, as Vohra says, a colossus at the intersection of economics and operations research.
In my small corner of the world, a very important paper was Shapley and Scarf (1974), "On Cores and Indivisibility," published in volume 1 number 1 of the Journal of Mathematical Economics. It built on Scarf's work on the core of games without sidepayments, and introduced a way of thinking about barter for indivisible goods, via the top trading cycle algorithm (which Shapley and Scarf attributed to David Gale).
