of beliefs (or ambiguity), imprecision of tastes (or multi-utility), and state dependence of utility. Examples include … phenomena, as well as state-dependent multi-utility generalisations of popular ambiguity models …Many decision situations involve two or more of the following divergences from subjective expected utility: imprecision …

Ambiguity refers to a decision situation under uncertainty when there is incomplete information about the likelihood of … ambiguity and ambiguity aversion. …

We show that ambiguity aversion increases the value of a statistical life as soon as the marginal utility of wealth is … higher if alive than dead. The intuition is that ambiguity aversion has a similar effect as an increase in the perceived … baseline mortality risk, and thus operates as the "dead anyway" effect. We suggest, however, that ambiguity aversion should …

A game-theoretic framework that allows for explicitly randomized strategies is used to study the e ect of ambiguity … predictions of two player games with ambiguity averse and with ambiguity neutral players are observationally equivalent. This … beliefs to the context of ambiguity aversion yields substantially di erent predictions even for the case with just two players. …

We develop a theory of optimal stopping problems under ambiguity in continuous time. Using results from (backward … from the agent's ambiguity aversion. We show how to use these general results for search problems and American Options. …

We consider optimal stopping problems for ambiguity averse decision makers with multiple priors. In general, backward …

with two regimes, and where households have generalized recursive smooth ambiguity preferences. The adopted class of … preferences permits a three-way separation of risk aversion, ambiguity aversion, and the attitude toward intertemporal … substitution. Ambiguity averse agents are ambiguous about the probability distribution of productivity growth. We show that in the …

This paper explicitly solves, in closed form, the optimal consumption and port folio choice for an ambiguity averse … are represented by the recursive multiple priors utility model developed by Chen and Epstein (2002). The investor …'s utility depends on both intermediate consumption and terminal wealth. Under the assumption of complete markets, I use the …

contribution, the paper extends the smooth ambiguity model by providing a threefold disentanglement between, risk aversion …, ambiguity aversion, and the propensity to smooth consumption over time. …
