We add some elements of prospect theory to an analytically tractable version of Lucas's " islands" model and show that the inclusion of reference dependence, declining sensitivity and loss aversion into the agents' utility function leads to four main results. First, the presence of behavioral elements negatively affects the natural level of output. Second, loss aversion reduces output variance. Third, the expected utility of a representative agent is generally lower than that obtained when loss aversion is absent. Fourth, the presence of loss aversion eliminates the paradoxical increase in expected utility that may be generated, in the standard model, by an increase in monetary policy uncertainty. © 2012 Elsevier B.V.

Abstract
We add some elements of prospect theory to an analytically tractable version of Lucas's " islands" model and show that the inclusion of reference dependence, declining sensitivity and loss aversion into the agents' utility function leads to four main results. First, the presence of behavioral elements negatively affects the natural level of output. Second, loss aversion reduces output variance. Third, the expected utility of a representative agent is generally lower than that obtained when loss aversion is absent. Fourth, the presence of loss aversion eliminates the paradoxical increase in expected utility that may be generated, in the standard model, by an increase in monetary policy uncertainty. © 2012 Elsevier B.V.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
