โฆ Synopsis
This paper analyses risk and risk aversion in the state-dependent utility model, which is useful for modelling health or life insurance purchase. We use Karni's (1983) definition of risk aversion, and extend the class of risks to which it can be applied.

This paper i defines the concept of a mean utility preserving spread across states (MUPSAS) for state dependent utility functions and analyzes the behavioural impact of shifts in the probability distribution of wealth across states such that overall mean utility is preserved.

In the expected utility case, the risk-aversion measure is given by the Arrow-Pratt index. Three proposals of a risk-aversion measure for the nonexpected utility case are examined. The first one sets "the second derivative of the acceptance frontier as a measure of local risk aversion." The second o
It is shown that von Neumann-Morgernstern (NM) expected utility maximization, as is currently practised, implies an upper bound on the percentage utility that can be sacrificed to reduce the probability or severity of a catastrophe. The major quantitative result of this paper is a simple tabular (an
