Fitting the CDO Correlation Skew: A Tractable Structural Jump-Diffusion Model

02-12-2005 We extend a well-known structural jump-diffusion model for credit risk to handle both correlations through diffusion of asset values and common jumps in asset value. Through a ... Read more

GSE Funding Advantages and Mortgagor Benefits: Answers from Asset Pricing

29-03-2005 We take an asset-pricing approach to model the funding advantage of Government Sponsored Enterprises (GSEs) such as Fannie Mae and Freddie Mac. In order to replicate stylized facts, we ... Read more

An Evaluation of the Base Correlation Framework for Synthetic CDOs

25-02-2005 In April 2004, JP Morgan introduced the notion of base correlations, a novel approach to quoting correlations for synthetic CDO tranches. This approach facilitates a simple relative ... Read more

Calibration of Structural Credit Risk Models: Implied Sensitivities and Liquidity Discounts

26-08-2004 Structural models of credit risk predict that certain firm and market features (leverage, volatility, risk-free rates) determine the price of credit-risky bonds. Unlike previous ... Read more

Reforming Housing Finance - Perspectives From Denmark

29-01-2004 We investigate the effect of adding a distinct feature from the Danish mortgage market to the US market, namely a buyback option, which enables mortgagors to buy back their share of the ... Read more

A Mixture Distribution approach to the Valuation of Mortgage Backed Securities

12-12-2002 This paper proposes a new valuation model for fixed-rate mortgage-backed securities which may be able to determine the price, option-adjusted spread, and option-adjusted duration ... Read more

Prepayment and the Valuation of Danish Mortgage Backed Bonds (1992)

12-12-2002 Svend Jakobsen, Prepayment and the Valuation of Mortgage Backed Bonds, Ph.D. Thesis, The Aarhus School of Business, 1992. The purpose of the thesis is to develop and test a pricing ... Read more

Measuring Value-at-Risk for MB Securities

12-12-2002 This paper investigates the computation of Value-at-Risk (VaR) measures for mortgage backed securities (MBSs) using data for the Danish MBS market. The current RiskMetrics proposal from ... Read more

Nonparametric Smoothing of Yield Curves

12-12-2002 This paper proposes a new nonparametric approach to the problem of interfering term structure estimates using coupon bond prices. The nonparametric estimator is defined on the basis of ... Read more

Hedging with a Misspecified Model

12-12-2002 This paper investigates hedging performance of misspecified models. Rather than constructing super-replicating strategies this paper suggests quantifying the hedging error by ... Read more

Finite Difference Computation of State-prices in Termstructure Models: With Applications to Calibration and MBS Analysis

12-12-2002 In this paper we consider the computation of state-prices in one-factor termstructure models. The contingent claim valuation problem is solved using the efficient method of finite ... Read more

Efficient Control Variates for Monte-Carlo Valuation of American Options

12-12-2002 In this paper we consider the application of control variates to the Monte-Carle valuation of American options. The main idea of the paper is to sample control variates at the exercise ... Read more

Improving the Least-Squares Monte-Carlo Approach

12-12-2002 In this paper we suggest two improvements to the Least-Squares Monte-Carlo approach of Longstaff & Schwartz (2001). Both focus on the accuracy and stability of the exercise strategy ... Read more

Valuation of Path-Dependent Interest Rate Derivatives in a Finite Difference Setup

12-12-2002 In this paper we study and implement a finite difference version of the augmented state variable approach proposed by Hull & White (1993) that allows for pathdependent securities. ... Read more

Mortgage Choice - The Danish Case

12-12-2002 In this paper we analyze the mortgage choice faced by Danish borrowers. Based on an analysis of the most popular Danish mortgage products, we argue that Adjustable-Rate Mortgages (ARM) ... Read more

Efficient Control Variates and Strategies for Bermudan Swaptions in a Libor Market Model

12-12-2002 This paper concerns the problem of valuing Bermudan swaptions in a Libor market model. In particular we consider various efficiency improvement techniques for a Monte Carlo based ... Read more

On the suboptimality of single-factor exercise strategies for Bermudan swaptions

12-12-2002 In this paper we examine the cost of using recalibrated single-factor models to determine the exercise strategy for Bermudan swaptions in a multi-factor world. We demonstrate that ... Read more
