Abstract We propose a new measure of deviations from expected utility theory. For any positive number e, we give characterization the datasets with rationalization that is within e (in beliefs, utility, or perceived prices) (EU) theory, under assumption risk aversion. The can then be used as how far data to EU apply our methodology three large-scale experiments. Many subjects in these experimen...

Uncertainty in probabilistic classifiers predictions is a key concern when models are used to support human decision making, broader pipelines or sensitive automatic decisions have be taken. Studies shown that most not intrinsically well calibrated, meaning their scores consistent with posterior probabilities. Hence being able calibrate these models, enforce calibration while learning them, has...

Uncertainty about which arguments or attacks should appear in an argument graph means that there is uncertainty as to the structure of the argument graph. When informal arguments are presented, there may be imprecision in the language used, and so the audience may be uncertain as to the structure of the argument graph as intended by the presenter of the arguments. For a presenter of arguments, ...

This paper analyzes a model of decision under ambiguity, deemed vector expected utility or VEU. According to the proposed model, an act f :Ω→X is evaluated via the functional V ( f ) = ∫

Using a system of axioms, this paper develops a general utility model of other-regarding preferences when opponents are unfamiliar, but they are not strictly anonymous in the sense that they may share some history. Based on two key axioms, an individual’s preferences over a vector of probability distributions are additively separable in the decision maker’s own outcome and each opponent’s outco...

It is well known that ex post e¢ cient mechanisms for the provision of indivisible public goods are not interim individually rational. However, the corresponding literature assumes that agents who veto a mechanism can enforce a situation in which the public good is never provided. This paper instead considers majority voting with uniform cost sharing as the relevant status quo. E¢ cient mechani...
