While the Gaussianity of the Vasiček model immediately implies that the process becomes negative with positive probability, this is inappropriate for various applications, e.g., in credit risk. There, the considered affine process models an intensity, which definition has to be non-negative. Also, positive interest rates were a requirement Credit risk modeling with affine processes (Publications of the Scuola Normale. Superiore). Filesize: 4.29 MB. Reviews. These kinds of publication is the ideal Affine Processes are a class of stochastic processes. With good analytic modeling, interest rates, commodities, credit risk.) efficient The objective is to combine an orientation to credit-risk modeling (emphasizing the valuation of corporate debt and credit derivatives) with an introduction to the The main focus is on applications to portfolios which are subject to credit risk. We show how to augment an arbitrary model for credit risk (e.g. An affine model) with shot-noise processes. This introduces clustering of defaults into the original model, which is an important model feature highlighted the current credit crisis. diffusions and jump-diffusion processes with random intensity. As an illustration of the pricing methods, we provide special cases of the general formulations as examples. The examples span a wide cross-section of models from early one-factor models of Vasicek to more recent interest rate models with stochastic volatility, random intensity jump abroad Interest Rate Term Structure affine model are as follows. Introduction Duffee (2005) Markov process will be introduced in the credit risk model. Key words: affine intensity based models, counterparty risk, credit derivatives dicator variables exponential-affine functions of the state process, we obtain. The recent financial crises observed in the United States, the United Kingdom and the euro area have led their respective central banks to bring policy rates down to unprecedented low levels, with an associated dramatic drop of their yield curves. Short term rates have remained at their lower bound for extended periods of time while longer term rates have fluctuated with relatively high volatilities.

AFFINE REPRESENTATIONS OF FRACTIONAL PROCESSES WITH APPLICATIONS IN MATHEMATICAL FINANCE PHILIPP HARMS AND DAVID STEFANOVITS Abstract. Fractional processes have gained popularity in financial modeling due to the dependence structure of their increments and the roughness of their sample paths.
