We solve the problem of optimal securitization for an issuer facing heterogeneous investorswith arbitrary time and risk preferences. We show that the optimal securitizationis characterized by multiple nonlinear tranches, and each investor gets a portfolio of thesetranches. In particular, when...

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 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...

A credit risk model for determining aggregated portfolio losses is suggested.Beside the common macrostructural dependencies between assetand recovery value, we incorporate possible inter-rm relations among theobligors of the portfolio. Through this channel we also establish relateddefault...

We consider an homogeneous class of assets, whose returns are driven by an unobservablefactor. We derive approximated prediction and pricing formulas for the future factorvalues and their proxies, when the size n of the class is large. Up to order 1=n, these approximationsinvolve solely...

We study how the interaction of agents with different beliefs about a firm’s future cash flows determines the jointbehavior of credit spreads, option implied volatilities, and stock returns. Beliefs heterogeneity influences the pricing kernelin a way that supports more realistic credit spreads...
