The number e can then be used as a …We propose a new measure of deviations from expected utility, given data on economic choices under risk and uncertainty … distance to the theory. We apply our methodology to three recent large-scale experiments. Many subjects in those experiments …

A general framework is described specifying how boundedly rational decision makers generate their choices. Starting … decision routines (by applying New Problem Solver). Our admittedly bold attempt is loosely related to some stylized …

We formulate a general theory of preferences over outcome-time-probability triplets and decompose uncertainty into risk … general discounted utility model which encompasses the main empirically supported discounted utility models. We show that our … axioms on preferences are satisfied in our general discounted utility model. Finally, we discuss the various explanations of …
