If a solution (on a closed family of games) satisfies dummy axiom (DUM) and independance of irrelevant strategies (IIS) then it also satisfies consistency (CONS) (proposition 2.21, Peleg and Tijs, 1996). The converse of this proposition is not true: CONS implies neither DUM nor IIS as shown in...

In the framework of the provision of one pure public good, we characterize the class of strategy-proof voting schemes on single-plateaued preferences over a convex and closed subset of the real line (the set of feasible levels of the public good).

The paper provides a general analysis of the types of models with E-Perturbations which have been used recently to discuss the evolution of social conventions. Two new measures of the size and structure of the basins of attraction of dynamic systems, the radius and coradius, are introduced in...

The possibility of cooperation in a repeated prisoner's dilemma without memory is investigated in an evolutionary framework where 1) some agents ('Vulcans') are morally commited to cooperation, 2) some others ('Klingons') are not commited at all, and 3) there is random matching.
