We propose a simple model of decision making under risk inspired by the "half-full, half-empty" glass metaphor. The …

We provide characterizations of four new rules for individual decision-making under complete uncertainty. They are what …. Keywords and Phrases: Complete uncertainty, Nonprobabilistic decision rules …

This paper analyses decision models with an uncertain set of alternatives defined by a deterministic objective function … and constraints with uncertain coefficients. Here, in contrast to decisions under risk, the stochastic distribution of … uncertain coefficients is not known. On the basis of an uncertain multiobjective decision model, we define efficient …

This paper estimates the determinants of decision time for different types of decision maker in the context of an … enable us to distinguish the factors influencing the decision time of each of these four types. We find that the different … Expected Utility and finally the Alpha type, whose decision time is always the lowest. Our results reflect the relative …

I experimentally examine whether feedback about others' choices provides an anchor for decision-making under ambiguity …

, subjects can reduce or even eliminate the ambiguity and turn the decision situation into one of risk. Under the assumption that …This paper focuses on information acquisition and individual decision making in ambiguous situations and presents a … choice between risky and ambiguous Ellsberg urns, we let them choose between a safe option and a risky lottery, whose risk is …

We investigate whether violations of canonical axioms of choice under risk are mistakes or a manifestation of true … preferences. Among the behavioral patterns that allow for a clear-cut interpretation on the decision level, we find that roughly …

decision errors can explain or be highly correlated with hyperbolic discounting and non-linear (inverse-S-shaped) probability … weighting. We find evidence that decision errors are strongly correlated with hyperbolic discounting but do not find that … decision errors are correlated with the strong inverse-S-shaped probability weighting (w(p)) patterns in our two samples. We …

Both economists and psychologists are interested in understanding decision making under uncertainty. Yet, they rely on … different concepts to analyse human behaviour: Economists use economic preference parameters rooted in utility theory, while …
