Pricing the multiple-choice nested knapsack problem
Drexl, Andreas; Jørnsten, Kurt - 2007
The multiple-choice nested knapsack problem (MCKP) is a generalization of the ordinary knapsack problem, where the set of items is partitioned into classes. The binary choice of selecting an item is replaced by taking exactly one item out of each class of items. Due to the fact that the MCKP is...

Subsidies, knapsack auctions and Dantzig's greedy heuristic
Ensthaler, Ludwig; Giebe, Thomas - 2009
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...

Ignorance is bliss: Rationality, information and equilibrium
Barde, Sylvain - 2011
An information-theoretic thought experiment is developed to provide a methodology for predicting endowment distributions in the absence of information on agent preferences. The allocation problem is first presented as a stylised knapsack problem. Although this knapsack allocation is intractable,...

How to allocate research (and other) subsidies
Ensthaler, Ludwig; Giebe, Thomas - 2010
A budget-constrained buyer wants to purchase items from a shortlisted set. Items are differentiated by observable quality and sellers have private reserve prices for their items. The buyer's problem is to select a subset of maximal quality. Money does not enter the buyer's objective function,...
