Comparative Risk Aversion for State-Dependent Preferences
The idea that preferences may be state-dependent fits naturally with an analysis of uncertainty based on explicit representation of random variables as state-contingent consumption or production bundles. In this paper we show how these concepts of risk-aversion may be extended to the case of state-dependent preferences, whether or not these preferences are autocomparable in the sense of Karni. We characterize autocomparability as a special case. We show how standard comparative static results, originally derived for the state-independent expected utility model, may be extended to general state-dependent preferences, without the requirement for additive separability.
