This paper proposes a measure of uncertainty-aversion analogous to the Arrow-Pratt Measure of risk aversion. We apply it to multiple priors and non additive probability models of uncertaity. In these models there is non distinction between uncertainty and aversion to it. Hence our theory can...

The endogeneity of equilibrium strategies makes modelling uncertainty about the behaviour of other economic players difficult. Recent developments in decision and game theory offer an opportunity to include strategic uncertainty as an explanatory variable in economic analysis. This paper...

This paper introduces E-capacities as a representation of beliefs which incorporates objective information about the probability of events. It can be shown that the Choquet integral of an E-capacity is the Ellsberg representation. The paper further explores properties of this representation of...

We examine the effect of introducing Knightian uncertainty into a simple model of public good provision. We find that uncertainty may reduce the free-rider problem if utility is concave in public goods or there are decreasing returns to scale in the production of public goods. It is possible...

In this paper we analyse the consequences of Knightian uncertainty for partnerships with symmetric linear production functions are analysed in a CEU framework. We propose an extension of Nash equilibrium in pure strategies for CEU-games with strategic uncertainty. We find that the presence of...
