Ranking of Weighted Majority Rules
A decision-making body may utilize a wide variety of different strategies when required to make a collective decision. In principle, we would like to use the most effective decision rule, that is, the rule yielding the highest probability of making the correct decision. However, in reality we often have to choose a decision rule out of some restricted family of rules. Therefore, it is important...
متن کاملOn the self-(in)stability of weighted majority rules
A voting rule f is self-stable (Barberà and Jackson [4]) if any alternative rule g does not have sufficient support in the society to replace f , where the decision between f and g is based on the rule f itself. While Barberà and Jackson focused on anonymous rules in which all agents have the same voting power, we consider here the larger class of weighted majority rules. Our main result is a c...
متن کاملThe Weighted Majority Algorithm
We study the construction of prediction algorithms in a situation in which a learner faces a sequence of trials with a prediction to be made in each and the goal of the learner is to make few mistakes We are interested in the case that the learner has reason to believe that one of some pool of known algorithms will perform well but the learner does not know which one A simple and e ective metho...
متن کاملVoting on Majority Rules∗
We analyze an overlapping generations model of voting on “reform projects”. These resemble investments in that they first require some investment expenditure and later pay off. Since the time during which old people get the benefit is shorter, or because older people are more wealthy and hence pay more taxes, they are more conservative (against reforms) than young people. We show that if people...
متن کاملEasy weighted majority games
In a weighted majority game each player has a positive integer weight and there is a positive integer quota. A coalition of players is winning (losing) if the sum of the weights of its members exceeds (does not exceed) the quota. A player is pivotal for a coalition if her omission changes it from a winning to a losing one. Most game theoretic measures of the power of a player involve the comput...
