Social anchor effects in decision-making under ambiguity
Lahno, Amrei M. - 2014
dynamics considerably differ between gain and loss domains. For gains, learning to be comparably ambiguity averse increases the …

On the psychological foundations of ambiguity and compound risk aversion
Wu, Keyu; Fehr, Ernst; Hofland, Sean; Schonger, Martin - 2024
Ambiguous prospects are ubiquitous in social and economic life, but the psychological foundations of behavior under ambiguity are still not well understood. One of the most robust empirical regularities is the strong correlation between attitudes towards ambiguity and compound risk which...

Complexity and hyperbolic discounting
Enke, Benjamin; Graeber, Thomas Wilhelm; Oprea, Ryan - 2023
A large literature shows that people discount financial rewards hyperbolically instead of exponentially. While discounting of money has been questioned as a measure of time preferences, it continues to be highly relevant in empirical practice and predicts a wide range of real-world behaviors,...

Uncertain rationality, depth of reasoning and robustness in games with incomplete information
Germano, Fabrizio; Weinstein, Jonathan; Zuazo-Garin, Peio - In: Theoretical economics : TE ; an open access journal in … 15 (2020) 1, pp. 89-122
Predictions under common knowledge of payoffs may differ from those under arbitrarily, but finitely, many orders of mutual knowledge; Rubinstein's (1989)Email game is a seminal example. Weinstein and Yildiz (2007) showed that the discontinuity in the example generalizes: for all types with...

Bayesian learning in unstable settings : experimental evidence based on the bandit problem
Payzan Le Nestour, Elise - 2010
When asset returns are unstable, investment performance directly depends on learning about their patterns optimally …. Without optimal learning, strong investment performance is not possible. Yet, optimal learning is often considered too complex … optimal learning, despite the high difficulty of the task. This finding suggests that investors can in fact learn optimally in …

Imperfect recall and time inconsistencies : an experimental test of the absentminded driver “paradox”
Levati, M. Vittoria; Uhl, Matthias; Zultan, Ro'i - 2010
Absentmindedness is a special case of imperfect recall which according to Piccione and Rubinstein (1997a) leads to time inconsistencies. Aumann, Hart and Perry (1997a) question their argument and show how dynamic inconsistencies can be resolved. The present paper explores this issue from a...

Belief updating: does the 'good-news, bad-news' asymmetry extend to purely financial domains?
Barron, Kai - 2016
Bayes' statistical rule remains the status quo for modeling belief updating in both normative and descriptive models of behavior under uncertainty. Recent research has questioned the use of Bayes' rule in descriptive models of behavior, presenting evidence that people overweight 'good news'...

Belief-Ordering Identification of Ambiguity Attitudes with Application to Partnership Dissolving Experiments
Yu, Ning Neil - 2013
To identify ambiguity attitudes in general environments, we propose a noncontroversial and easy-to-apply method that first orders beliefs by their "favorableness," and then make inferences based on choices. In our first-price two-person partnership dissolving auction experiments, the partners...

Experimental evidence on the relationship between perceived ambiguity and likelihood insensitivity
Henkel, Luca - 2022
Observed individual behavior in the presence of ambiguity is characterized by insufficient responsiveness to changes in subjective likelihoods. Such likelihood insensitivity under ambiguity is integral to theoretical models and predictive of behavior in many important domains such as financial...
