We contribute a new insight into the pre-crisis massive levered exposures to default risk by formulating a parsimonious, closed-form analysis of conspicuous risk taking in default-prone assets. Under no arbitrage, default risk is compensated by an ‘yield pickup’ that can strongly attract aggressive investors via an investment horizon effect in their optimal non-myopic portfolios. We show that default risk decoupled from event risk does not discourage the formation of markedly geared portfolios. Our results add a new portfolio-based perspective to a mainstream model of default risk: even if arbitrage-free, the model may not find unconstrained support in general equilibrium.

Abstract
We contribute a new insight into the pre-crisis massive levered exposures to default risk by formulating a parsimonious, closed-form analysis of conspicuous risk taking in default-prone assets. Under no arbitrage, default risk is compensated by an ‘yield pickup’ that can strongly attract aggressive investors via an investment horizon effect in their optimal non-myopic portfolios. We show that default risk decoupled from event risk does not discourage the formation of markedly geared portfolios. Our results add a new portfolio-based perspective to a mainstream model of default risk: even if arbitrage-free, the model may not find unconstrained support in general equilibrium.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
