Prior research on 'strategic voting' has reached the conclusion that unanimity rule is uniquely bad: it results in destruction of information, and hence makes voters worse off. We show that this conclusion depends critically on the assumption that the issue being voted on is exogenous, i.e.,...

This paper studies a collective decision problem in which a group of individuals with interdependent preferences vote whether or not to implement a public project of unknown value. A utilitarian social planner aggregates these votes according to a majority rule; but, unlike what is commonly...

In the paper, we study a relation between command games proposed by Hu and Shapley and an influence model. We show that our framework of influence is more general than the framework of the command games. We define several influence functions which capture the command structure. These functions...

Experiments can be used to relax technical assumptions that are made by necessity in theoretical analysis, and further test the robustness of theoretical predictions. To illustrate this point we conduct a three-person bargaining experiment examining the effect of different decision rules...

A committee of experts votes between a multi-attribute alternative and status quo. Each expert is a biased specialist who can privately evaluate only one attribute and puts more weight on it. We study whether a social-minded principal would compose the committee of more or less biased experts....

We analyze and evaluate the different decision rules describing the Council of Ministers of the EU starting from 1958 up to date. Most of the existing studies use the Banzhaf index (for binary voting) or the Shapley-Shubik index (for distributive politics). We argue in favor of the nucleolus as...

Social, economic, and organizational development require a degree of stable policy making. The instability of group decision making under majority rule has preoccupied social theorists since Condorcet in the late 18th century. In theory, subtle institutional modifications to pure majority rule...

This chapter surveys the literature on strategy proofness from a historical perspective. While I discuss the connections with other works on incentives in mechanism design, the main emphasis is on social choice models.
