Robust Decision-making Under Ambiguity
Most of management research, following on the paradigm of expected utility theory, has developed complex models of optimal managerial action in the presence of uncertainty. Still, the assumption that managers assign probabilities to outcomes, and consequently optimize their actions has come under criticism from a number of empirical studies. Researchers, working on probability assessments, have...
متن کاملDecision making under uncertainty and ambiguity
This paper presents and analyzes the results of two experiments including small decision problems. In the experiments, subjects are asked to choose one of two alternatives for a few thousand times. First experiment, where payoff structure is clearly told, is carried out to explore choice under uncertainty by examining whether expected utility theory holds or not. Second experiment, where subjec...
متن کاملEpistemic Foundation of Decision Making under Ambiguity
In the seminal works, Mukerji (1997) and Ghirardato (2001) explain the notion of ambiguity in terms of incompleteness of what the decision maker (DM) knows and demonstrate that such limitation may lead to a non-additive specification of DM’s beliefs. However, these theories do not relate this issue to well established formal models of knowledge. We show that translating the decision theoretic s...
متن کاملP300 and Decision Making under Risk and Ambiguity
Our study aims to contrast the neural temporal features of early stage of decision making in the context of risk and ambiguity. In monetary gambles under ambiguous or risky conditions, 12 participants were asked to make a decision to bet or not, with the event-related potentials (ERPs) recorded meantime. The proportion of choosing to bet in ambiguous condition was significantly lower than that ...
متن کاملDecision making under risk and under ambiguity in Parkinson's disease.
In the present study we investigate decision making under ambiguity and decision making under risk in Parkinson's disease (PD) patients without cognitive impairment and in patients affected by Parkinson's disease dementia (PDD). In decisions under ambiguity, participants are not aware of the rules for gains and losses and have to learn about the utility of their selections through feedback. The...
