タイトル：The Kuhn-Tucker theorem and the separation theorem in discrete settings and their application to auctions
【abstract】
Using a notion of convexity in discrete convex analysis, we introduce a discrete analogue of the Kuhn-Tucker theorem. We apply it to an auction model and show that Ausubel’s (2006) auction can be viewed as the process of finding a saddle point of the Lagrange function. We also provide an economic interpretation to Ausubel’s (2006) auction by using the separation theorem for discrete convex sets.
