Nominal and real U.S. interest rates (1997–2007) are combined with inflationexpectations from the Survey of Professional Forecasters to calculate time series ofrisk premia. It is shown that survey data on inflation and output growth uncertainty,as well as a proxy for liquidity premia can...

In this paper, we consider the coherent theory of (epistemic) uncertainty ofWalley, in whichbeliefs are represented through sets of probability distributions, and we focus on the problemof modeling prior ignorance about a categorical random variable. In this setting, it isa known result that a...

We develop a convenient structural framework for the joint model-ing of credit spreads, stock prices, stock options and basket creditderivatives, using a multivariate structural ¯rm value model withskewed asset returns. We show that our setting successfully addressesseveral empirical facts,...

We develop a new completely affine model of the term structure of interest rates, in which the statevariables evolve as a matrix-valued process of stochastically correlated factors. This setting grants a newelement of flexibility in the simultaneous modeling of stochastic volatilities and...

We develop infinitesimally robust statistical procedures for general diffusion pro-cesses. We first prove existence and uniqueness of the times series influence functionof conditionally unbiased M{estimators for ergodic and stationary diffusions, underweak conditions on the (martingale)...

In 1992 Russia unified the multiple exchange rates that had applied to international transactions. This paper describes the multiple exchange rate system that existed in Russia prior to mid-1992 and undertakes a theoretical exploration of the effects of the exchange rate unification that took...
