Book excerpt: We extend the analysis of risk aversion with state-dependent preferences to the Rank-dependent Expected Utility theory. We find that in this extended theory, for two preference relations to be comparable in risk aversion, not only do their reference sets need to coincide (a condition first introduced by Karni (1983, 85) in the original Expected Utility framework), but they must also rank the prospective state-dependent outcomes in the same manner. We formalize this additional condition by introducing the concept of certainty sets. Under our condition of comparability, various results and characterizations of interpersonal comparison of risk aversion are obtained. The implications for a specific insurance problem are also discussed.
