Informational requirements of social choice rules
The needed amount of information to make a social choice is the cost of information processing, and it is a practically important feature of social choice rules. We introduce informational aspects into the analysis of social choice rules and prove that (i) if an anonymous, neutral, and monotonic social choice rule operates on minimal informational requirements, then it is a supercorrespondence ...
متن کاملOn combining implementable social choice rules
We study if (and when) the intersections and unions of social choice rules that are implementable with respect to a certain equilibrium concept are themselves implementable with respect to that equilibrium concept. While the results for dominant strategy equilibrium are mostly of negative nature, the situation is di¤erent in the case of Nash implementation. We nd that the union of any set of N...
متن کاملManipulating two stage voting rules
We study the computational complexity of computing a manipulation of a two stage voting rule. An example of a two stage voting rule is Black’s procedure. The first stage of Black’s procedure selects the Condorcet winner if they exist, otherwise the second stage selects the Borda winner. In general, we argue that there is no connection between the computational complexity of manipulating the two...
متن کاملGame Forms versus Social Choice Rules as Models of Rights
The paper begins by defining multi-valued game forms which generalize social choice rules. It also defines the effectiveness relations that represent the rights induced by such game forms. When one-way instead of two-way rights are allowed, it also demonstrates yet further difficulties in finding a social choice rule to respect all rights. Finally, to deal with the problem that game forms typic...
متن کاملSecurely implementable social choice rules with partially honest agents
We define secure implementation with partially honest agents in a social choice model and we show that strategy-proofness is a necessary and sufficient condition for it. This result offers a behavioral foundation for rectangularity ; and it remains valid even with only one partially honest agent. We apply the concept to a single-crossing voting environment, and we prove that it characterizes th...
