This chapter reviews the experimental literature on ambiguity attitudes, focusing on three
topics. First, it considers various approaches to operationalize ambiguity in experiments …

How we estimate uncertainty is important in decision neuroscience and has wide-ranging
implications in basic and clinical neuroscience, from computational models of optimality to …

We study risk attitudes, ambiguity attitudes, and time preferences of 661 children and
adolescents, aged ten to eighteen years, in an incentivized experiment and relate …

We explore situations in which a decision maker bears responsibility for somebody else's
outcomes as well as for her own. We study such choices for gains and losses, and for …

Animals (including humans) often face circumstances in which the best choice of action is
not certain. Environmental cues may be ambiguous, and choices may be risky. This paper …

We propose an integrated theoretical framework that captures the diverse motives driving
the preference to obtain or avoid information. Beyond the conventional desire for information …

The value of information is studied in a non-expected utility model of ambiguity with second-
order probabilities. Information that reduces ambiguity has a positive value for ambiguity …

Predictions provided by action-outcome probabilities entail a degree of (first-order)
uncertainty. However, these probabilities themselves can be imprecise and embody second …

We propose that ambiguity aversion, as introduced in the literature on decision making
under uncertainty, drives a preference for established brands in multiattribute choices …

The decision to recall a product can significantly affect an operations manager's career, the
credibility and financial performance of the firm, and the safety of customers. Despite the …
