The evolutionary stability of optimism, pessimism and complete ignorance

Schipper, Burkhard - 2005

We provide an evolutionary foundation to evidence that in some situations humans maintain optimistic or pessimistic attitudes towards uncertainty and are ignorant to relevant aspects of the environment. Players in strategic games face Knightian uncertainty about opponents' actions and maximize...

The evolutionary stability of optimism, pessimism, and complete ignorance

Schipper, Burkhard - 2019

We provide an evolutionary foundation to evidence that in some situations humans maintain either optimistic or pessimistic attitudes towards uncertainty and are ignorant to relevant aspects of the environment. Players in strategic games face Knightian uncertainty about opponents' actions and...

Impossibility results for infinite-electorate abstract aggregation rules

Herzberg, Frederik; Eckert, Daniel - 2009

impossibility results for free ultrafilters: The domain of an ultraproduct over a free ultrafilter extends the individual factor … preferences that it generalises. This is due to the fact that the typical judgment aggregation problem induces an ultrafilter on …, dictatorship then immediately follows from the principality of an ultrafilter on a finite set. This is not the case for an infinite …

Social choice of convex risk measures through Arrovian aggregation of variational preferences

Herzberg, Frederik - 2010

This paper studies collective decision making with regard to convex risk measures: It addresses the question whether there exist nondictatorial aggregation functions of convex risk measures satisfying Arrow-type rationality axioms (weak universality, systematicity, Pareto principle). Herein,...

Inferring preferences from choices under uncertainty

Kuzmics, Christoph - 2012

If a decision maker, in a world of uncertainty à la Anscombe and Aumann (1963), can choose acts according to some objective probability distribution (by throwing dice for instance) from any given set of acts, then there is no set of acts that allows an experimenter to test more than the Axiom...

Intertemporal equilibria with knightian uncertainty

Dana, Rose-Anne; Riedel, Frank - 2010

We study a dynamic and infinite-dimensional model with Knightian uncertainty modeled by incomplete multiple prior preferences. In interior efficient allocations, agents share a common risk-adjusted prior and use the same subjective interest rate. Interior efficient allocations and equilibria...
