Rules for aggregating information
نویسندگان
چکیده
We present a model of information aggregation in which agents’ information is represented through partitions over states of the world. We discuss three axioms, meet separability, upper unanimity, and non-imposition, and show that these three axioms characterize the class of oligarchic rules, which combine all of the information held by a pre-specified set of individuals. JEL classification: D70, D71, D72

Fuzzy rule-based systems
Relations between similarity-based systems, evaluating similarity to some prototypes, and fuzzy rule-based systems, aggregating values of membership functions, are investigated. Similarity measures based on information theory and probabilistic distance functions lead to a new type of membership functions applicable to symbolic data. Fuzzy membership functions on the other hand lead to a new typ...
متن کاملTruth - tracking judgment aggregation over interconnected issues ∗
This paper analyses the problem of aggregating judgments over multiple interconnected issues. Voters share a common preference for reaching true collective judgments, but hold private information about what the truth might be. Information conflicts may occur both between and within voters. Following Bozbay, Dietrich and Peters (2014), we assume strategic voting in a Bayesian voting game setting...
متن کاملDistance-based rules for weighted judgment aggregation
Cooperating agents need to reach group decisions on several logically related issues. These decision-making problems are studied in social choice theory by the discipline of judgment aggregation. Judgment aggregation produces group decisions by aggregating individual answers to binary questions, however existing aggregation rules are defined for a very restricted setting, insufficient for aggre...
متن کاملAggregation and maintenance for database mining
Database mining must capture the dynamics of data in the real-world. In other words, mining models would be able to maintain all changed rules when a database is updated. This paper presents a new model of aggregating association rules aimed at not only maintaining association rules in dynamical databases, but also aggregating association rules from dierent data sources. Indeed, this aggregati...
متن کاملInformation elicitation for decision making
Proper scoring rules, particularly when used as the basis for a prediction market, are powerful tools for eliciting and aggregating beliefs about events such as the likely outcome of an election or sporting event. Such scoring rules incentivize a single agent to reveal her true beliefs about the event. Othman and Sandholm [16] introduced the idea of a decision rule to examine these problems in ...
