Abstract: We propose a general equilibrium framework for pricing defaultable bonds that are subject to contagion-risk when the representative agent has fragile beliefs (Hansen and Sargent (2009)). We identify conditions for which the marginal utility of the agent with fragile beliefs generate time-consistent state prices. Even though capturing contagion implies that our intensity-based model falls outside of the "doubly stochastic" framework, bond prices remain tractable, in turn facilitating empirical investigation. We apply this model to sovereign countries in the European Union (EU). The model can justify large and highly correlated credit spreads even when default probabilities and correlations in macroeconomic fundamentals are low.

JEL Classification: G12, G13.
