In this paper we consider the effect of ambiguity on the private provision of public goods. Equilibrium is shown to …

Many theories have been developed to model decision behavior under ambiguity. In this paper we empirically investigate …

-additive survival beliefs expressing ambiguity attitudes. We embed these neo-additive survival beliefs as decision weights in a Choquet …

We examine the impact of ambiguity on economic behaviour. We present a relatively non-technical account of ambiguity … and show how it may be applied in economics. Optimistic and pessimistic responses to ambiguity are formally modelled. We … also examine the effects of ambiguity on peace processes. It is shown that ambiguity can act to select equilibria in …

with a probability distribution. Consequently, they do not allow for Knightian uncertainty, or ambiguity, with respect to … accident risk and cannot accommodate optimism (ambiguity loving) or pessimism (ambiguity aversion). This paper presents a … unilateral accident model under ambiguity. To incorporate ambiguity, I adopt the Choquet expected utility framework and represent …

utility functions, where concavity is an expression of ambiguity aversion and/or risk aversion. This paper extends the … analysis to α-maxmin expected utility, Choquet expected utility, and Cumulative Prospect Theory, which accommodate ambiguity …
