Presented by Paan Jindapon, University of Alabama


The notion of risk apportionment, introduced by Eeckhoudt and Schlesinger (2006) and generalized by Eeckhoudt et al. (2009), has proven to be useful in understanding decision making in risky environments.  A decision maker with a preference for risk apportionment prefers putting two independent risk increases in separate states to combining them in a single state.  In this paper, we study comparative risk apportionment, the issue of comparing the strength of risk apportionment preference between two decision makers.  Under expected utility theory, we find that the (n/m)th-degree Ross more risk aversion of Liu and Meyer (2013) is a sufficient condition for comparative nth-degree risk apportionment, whereas the corresponding (n/m)th-degree Arrow-Pratt more risk aversion is a necessary condition.
