We build a general model for pricing defaultable claims. In addition to the usual ab-sence of arbitrage assumption, we assume that one defaultable asset (at least) looses value when thedefault occurs. We prove that under this assumption, in some standard market ltrations, defaulttimes are...

Using an options-based approach, we compute the value of the state guaranteefor the liability side of CS and UBS. The insurance premiums forthese two system-relevant banks are calculated in a dynamic setup from2004 until 2009 in quarterly steps for time horizons of one and five years.The model...

We propose a simple but effective estimation procedure to extract the level and the volatilitydynamics of a latent macroeconomic factor from a panel of observable indicators. Our approachis based on a multivariate conditionally heteroskedastic exact factor model that cantake into account the...

The persistence of financial instability calls into question the adequacy of the current regulatory regime. Acritical review of the three pillars at the core of current financial regulation exposes some structural flaws.[...]

Stein’s lemma is extended to the case where asset returns have skewed and leptokurticdistributions. The risk premium is still the negative of the covariance of theexcess return with the log SDF.[...] Paul Söderlind]

We develop a novel class of time-changed Lévy models which are tractable and readily applicable, capture the leverage effect, and exhibit pure jump processes with finite or infinite activity. Our models feature four nested processes reflecting market, volatility and jump risks, and observation...

When investors have incomplete information, expected returns, as measured by an econometrician, deviate from those predicted by standard asset pricing models by including a term that is the product of the stock's idiosyncratic volatility and the investors' aggregated forecast errors. If...
