We call behavior inertial if it does not react to the apparent arrival of relevant information. In a context where the precise information content of signals is subjective, we formulate an axiom that captures inertial behavior, and provide a representation that explains such behavior as that of...

We propose a class of dynamic models that capture subjective (and hence unobservable) constraints on the amount of information a decision maker can acquire, pay attention to, or absorb, via an Information Choice Process (icp). An icp specifies the information that can be acquired about the...

We introduce a new class of preferences — which we call additive-belief-based (ABB) —that captures a general and yet tractable approach to belief-based utility, and that encompasses many popular models in the behavioral literature. We show that the general class of ABB preferences and two...

We extend and apply salience theory to choices over lotteries with multiple dimensions, such as insurance plans with deductibles and premiums, or monetary and non-monetary rewards. This extension can explain empirically observed dominated choices with large welfare costs to consumers (the...
