A General Framework for Term Structure Models Driven by Lévy Processes∗
نویسنده
چکیده
We describe a framework in which to generalize the Heath, Jarrow and Morton model for the term structure of interest rates. We represent the model in terms of the triplet of characteristics of the underlying semimartingales. We state and prove the necessary and sufficient conditions for absence of arbitrage in terms of the characteristics of the price process. The methodology is then extended to find sufficient conditions for absence of arbitrage in the defaultable case.

Existence of Affine Realizations for Lévy Term Structure Models
We investigate the existence of affine realizations for term structure models driven by Lévy processes. It turns out that we obtain more severe restrictions on the volatility than in the classical diffusion case without jumps. As special cases, we study constant direction volatilities and the existence of short rate realizations.
متن کاملTerm structure models driven by general Lévy processes
Empirical investigations ([1], [2]) showed that purely discontinuous Lévy processes allow more realistic modeling of financial time series. We present a new class of bond price models that can be driven by a wide range of Lévy processes (Lt). We do not just replace Brownian motion (Bt) in the standard diffusion model for the price of a zero coupon bond with maturity T dP (t, T ) = P (t, T )(r(t...
متن کاملCDO term structure modelling with Lévy processes and the relation to market models
This paper considers the modelling of collateralized debt obligations (CDOs). We propose a top-down model via forward rates generalizing Filipović, Overbeck and Schmidt (2009) to the case where the forward rates are driven by a finite dimensional Lévy process. The contribution of this work is twofold: we provide conditions for absence of arbitrage in this generalized framework. Furthermore, we ...
متن کاملSymmetries in Lévy Term Structure Models
Symmetry results between call and put options have been widely studied in equity markets. We provide similar symmetry results between caps and floors in a Heath–Jarrow–Morton, a LIBOR and a forward price model, driven by time-inhomogeneous Lévy processes. On the way, we review the basic properties of these models.
متن کاملCdo Market Models Driven by Time-inhomogeneous Lévy Processes
This paper considers a top-down approach for CDO valuation and proposes a market model. We extend previous research on this topic in two directions: on the one side, we use as driving process for the interest rate dynamics a time-inhomogeneous Lévy process, and on the other side, we do not assume that all maturities are available in the market. Only a discrete tenor structure is considered, whi...
