Subsidies, Knapsack Auctions and Dantzig's Greedy Heuristic

Ludwig Ensthaler and Thomas Giebe ()

No 880, Discussion Papers of DIW Berlin from DIW Berlin, German Institute for Economic Research

Abstract: A budget-constrained buyer wants to purchase items from a shortlisted set. Items are differentiated by quality and sellers have private reserve prices for their items. Sellers quote prices strategically, inducing a knapsack game. The buyer's problem is to select a subset of maximal quality. We propose a buying mechanism which can be viewed as a game theoretic extension of Dantzig's greedy heuristic for the classic knapsack problem. We use Monte Carlo simulations to analyse the performance of our mechanism. Finally, we discuss how the mechanism can be applied to award R&D subsidies.
