arbitrage-free model, capturing both stochastic volatility and jumps. Jump-risk premia uncovered from the joint data respond … quickly to market volatility, becoming more prominent during volatile markets. This form of jump-risk premia is important not … only in reconciling the dynamics implied by the joint data, but also in explaining the volatility quot;smirksquot; of cross …

In this paper we suggest a new technique to construct Markov processes by means of products of copula functions, in the spirit of Darsow et al, (1992). The approach requires to define: i) a sequence of distribution functions of the increments of the process; ii) a sequence of copula functions...

Realized volatility is a nonparametric ex-post estimate of the return variation. The most obvious realized volatility … a more general framework. Along the way we clarify how the realized volatility and quadratic return variation relate to …

Stochastic volatility models such as those of Heston (1993) and Hull and White (1987) are often used to model … volatility risk in the pricing and hedging of contingent claims on risky assets. Some recent empirical evidence has shown that … these models under general specifications often do not fully capture the volatility dynamics observed. This paper provides …

This paper illustrates a semi-parametric approach to static and dynamic asset allocation problems in terms of the moments of a multivariate distribution. By use of a general class of H-distributions, we reconstruct the portfolio density function from the moment sequence derived from the...

We use macro finance models to study the interaction between macro variables and the Brazilian sovereign yield curve using daily data. We calculate the model implied default probabilities and a measure of the impact of macro shocks on the probabilities. An extension of the Dai-Singleton...

The evolution of the yields of different maturities is related and can be described by a reduced number of commom latent factors. Multifactor interest rate models of the finance literature, common factor models of the time series literature and others use this property. Each model has advantages...
