We examine asset prices in a representative-agent model of general equilibrium. Assuming only that individuals are risk averse, we determine conditions on the changes in asset risk that are both necessary and sufficientfor the asset price to fall. We show that these conditions neither imply, nor...

The COVID-19 pandemic has highlighted the impacts that rare disasters can have on credit markets. We discuss and quantify the asset-pricing implications of disaster risk on the risk-free rate, credit spreads, and their term structures. The findings underscore the heterogeneous effects of...

I provide a measure of time-varying tail risk in credit markets based on a dynamic power-law model. Credit tail risk is estimated from extreme price fluctuations of credit default swaps (CDS) on government debt. Tail returns are described by a power-law for core and peripheral countries within...

This paper proposes a quantitative general equilibrium model with credit market frictions to explain the observed stylized facts of micro uncertainty (dispersion of realized firm-level outcomes) and macro uncertainty (volatility of aggregate economic variables). They are conceptually different...
