We define pessimistic, respectively optimistic, investors as CEU (Choquet expected utility) decision makers who update their pessimistic, respectively optimistic, capacities according to a pessimistic (Dempster-Shafer), respectively optimistic, update rule. We demonstrate that pessimistic rather...

On average, "young" people underestimate whereas "old" people overestimate their chances to survive into the future. We parameterize a learning model of subjective survival beliefs with psychological biases such that we replicate these patterns. We then combine this learning model with an...

On average, young people underestimate whereas old people overestimate their chances to survive into the future. We employ a subjective survival belief model proposed by Ludwig and Zimper (2013), which can replicate these patterns. The model is compared with hyperbolic discounting within a...

On average, "young" people underestimate whereas "old" people overestimate their chances to survive into the future. We adopt a Bayesian learning model of ambiguous survival beliefs which replicates these patterns. The model is embedded within a non-expected utility model of life-cycle...

On average, “young” people underestimate whereas “old” people overestimate their chances to survive into the future. Such subjective survival beliefs violate the rational expectations paradigm and are also not in line with models of rational Bayesian learning. In order to explain these...

On average, ``young" people underestimate whereas ``old" people overestimate their chances to survive into the future. We adopt a Bayesian learning model of ambiguous survival beliefs which replicates these patterns. The model is em- bedded within a non-expected utility model of life-cycle...

This paper develops a theoretical model for the formation of subjective beliefs on individual survival expectations. Data from the Health and Retirement Study (HRS) indicate that, on average, young respondents underestimate their true sur- vival probability whereas old respondents overestimate...
