Suppose that a group of agents having divergent expectations can share risks efficiently. We examine how this group should behave collectively to manage these risks. We show that the beliefs of the representative agent is in general a function of the group.s wealth level, or equivalently, that...

Risk-assessment and risk-taking in various forms are among the most important tasks financial professionals face in their daily work. A large body of experimental studies has shown a substantial effect of the decision domain (gain vs loss domain) on risk-taking, predominantly among students. In...

We report on a laboratory experiment testing for the presence of loss aversion, as separate from risk aversion, utilizing an asset integration protocol designed to ensure that a loss of cash provided by the experimenter is viewed as a real loss by experimental participants. Our experimental...
