A collective decision problem is described by a set of agents, a pro…le of single-peaked preferences over the real line and a number k of public facilities to be located. We consider public facilities that do not su¤er from congestion and are non-excludable. We provide a characterization of the class of rules satisfying Pareto-e¢ ciency, object-population monotonicity and sovereignty. Each rule...

Abstract We conduct laboratory experiments for the multi-unit Vickrey auction with and without advice to subjects on strategy-proofness. The rate of truth-telling among stays at 20%, whereas increases 47% those who have received advice. By conducting similar pay-your-bid auction, which is not strategy-proof, we confirm that increase in due significantly net effect (i.e., beyond so-called experi...

in this paper, we analyze the effect of lack of capital investment on energy projects using game theory in the guise of cooperative games. we focus on the energy projects in the provincial level as case study during 2010-2011. therefore, we design a theoretical model of the lack of capital investment as a factor influencing the implement of energy projects. in the experimental section, we deter...
