Aggregation of Models, Choices, Beliefs, and Preferences

  title={Aggregation of Models, Choices, Beliefs, and Preferences},
  author={Hamed Hamze Bajgiran and Houman Owhadi},
A natural notion of rationality/consistency for aggregating models is that, for all (possibly aggregated) models A and B, if the output of model A is fpAq and if the output model B is fpBq, then the output of the model obtained by aggregating A and B must be a weighted average of fpAq and fpBq. Similarly, a natural notion of rationality for aggregating preferences of ensembles of experts is that, for all (possibly aggregated) experts A and B, and all possible choices x and y, if both A and B… 
Aggregation of Pareto optimal models
Pareto efficiency is a concept commonly used in economics, statistics, and engineering. In the setting of statistical decision theory, a model is said to be Pareto efficient/optimal (or admissible)

Aggregation Procedure for Cardinal Preferences: A Formulation and Proof of Samuelson's Impossibility Conjecture
SAMUELSON MADE THE CONJECTURE stated above in his 1967 paper [7]. He also formalized there the axiom of independence of irrelevant alternatives for cardinal preferences, used here. Preference are
An expected utility theory for state-dependent preferences
This note is a generalization and improved interpretation of the main result of Karni and Schmeidler (An Expected utility theory for state-dependent preferences. Working paper no. 48-80 of the
A Mixture-Set Axiomatization of Conditional Subjective Expected Utility
An axiomatization is presented for a Savage-type conditional subjective expected utility model. The axioms consist of extensions of the Herstein-Milnor [11] axioms for "measurable" utility, a
Conditioning and Aggregation of Preferences
This paper develops a general framework for modeling choice under uncertainty that extends subjective expected utility to include nonseparabilities, state-dependence, and the effect of subjective or
Path Independent Choices
The structure of a real linear space enables us to interpret a point x, in the convex hull of a set S, as a lottery over the elements of S.
The paper provides several axiomatizations of the concept of "path independence" as applied to choice functions defined over finite sets. The axioms are discussed in terms of their relationship to
Inductive Inference: An Axiomatic Approach
A predictor is asked to rank eventualities according to their plausibility, based on past cases. We assume that she can form a ranking given any memory that consists of finitely many past cases. Mild
Conditional expected utility
Let $${\mathcal {E}}$$E be a class of events. Conditionally Expected Utility decision makers are decision makers whose conditional preferences $$\succsim _{E}$$≿E, $$E\in {\mathcal {E}}$$E∈E, satisfy
Cardinal Welfare, Individualistic Ethics, and Interpersonal Comparisons of Utility
I T HE naive concept of social welfare as a sum of intuitively measurable and comparable individual cardinal utilities has been found unable to withstand the methodological criticism of the Pareto
