Rarely, if ever. do parties contemplating a joint project commit resources without engaging in nonbindin- discussions about who does what. To examine the role of such discussions, we model the investment decision as a voluntary contribution game where each player is privately informed of her...

We review the recent theoretical developments toward understanding the Mott phases and quantum phase transition of extended Bose–Hubbard models on lattices in two spatial dimensions. We focus on the description of these systems using the dual vortex picture and point out the crucial role...

Research in human information processing demonstrates that the presence of irrelevant information has an adverse effect on the quality of decisions. Decision makers are unable to identify and separate the effect of irrelevant information, thereby reducing the quality of decisions. The propensity...
