In this paper, we assess the degree to which four of the most commonly used models of risky decision making can explain … enough to approximate Kahnenman and Tversky's prospect theory and that for certain parametric values will yield the expected … explain the decision-making behavior of the majority of our subjects. Surprisingly, we find that the choice behavior of the …

In its attempt to model financial markets and the behavior of firms, modern finance theory starts from a set of … normatively appealing axioms about individual behavior. Specifically, people are said to be risk-averse expected utility … paradigm may be criticized, however, because (1) the assumptions are descriptively false and incomplete, and (2) the theory …

reports on direct measures of preference parameters relating to risk tolerance, time preference, and intertemporal … of preference parameters display substantial heterogeneity. The majority of respondents fall into the least risk …-tolerant group, but a substantial minority display higher risk tolerance. The individual measures of intertemporal substitution and …

implications of risky behaviors by youths. I begin by reviewing perspectives on youth risk-taking from traditional rational … risk-taking by youths, and how this compares to adults. I review the evidence on youth risk taking from the studies in this … risk taking by youths, (b) despite this, these factors are not very successful in predicting the dramatic time series …

We propose a model of optimal decision making subject to a memory constraint. The constraint is a limit on the … complexity of memory measured using Shannon's mutual information, as in models of rational inattention; but our theory differs …
