We consider a structural model to design and evaluate the American call, conversion, and put options embedded in corporate bonds. We use dynamic programmin...
BibTeX reference
The estimation of the structural model poses a major challenge as its underlying asset (the firm's asset value) is not directly observable. We extend the m...
BibTeX reference
We use stochastic dynamic programming to design and solve an extended structural setting for which the illiquidity of the firm's assets under liquidation i...
BibTeX referenceNORTA for portfolio credit risk
We use NORTA (NORmal To Anything) to enhance normal credit-risk factor settings in modeling common risk factors and capturing contagion effects...
BibTeX reference
An exchangeable bond is a debt that is convertible into shares of a firm's equity other than the bond's issuer. We evaluate an exchangeable bond within a two...
BibTeX reference
Most structural models for valuing corporate securities assume a geometric-Brownian motion to describe the firm's assets value. However, this does not reflec...
BibTeX reference
We develop a general structural model for valuing risky corporate debts that takes into account both default and interest rate risk. We propose a two-dimensi...
BibTeX reference
Lévy processes provide a solution to overcome the shortcomings of the lognormal hypothesis. A growing literature proposes the use of pure-jump Lévy processe...
BibTeX referenceDynamic programming and parallel computing for valuing two-dimensional american-style options
We propose a dynamic program coupled with finite elements for valuing two-dimensional American-style options. To speed-up our procedure, we use parallel comp...
BibTeX reference
We propose a quasi-analytical approach for valuing American-style options under Gaussian and double exponential jumps à la Merton (1976) and Kou (2002). Our ...
BibTeX reference
We design and implement a dynamic program (DP) for valuing corporate securities, seen as derivatives on a firm's assets, and computing the term structure o...
BibTeX reference
We propose a stochastic dynamic program for valuing options on stock-index futures. The model accounts for deterministic, seasonally varying dividends gene...
BibTeX reference
The aim of this paper is to compute upper and lower bounds for convex value functions of derivative contracts. Laprise et al. (2006) compute bounds for Ame...
BibTeX referenceA Review of Survival Trees
This paper presents a non--technical account of the developments in tree--based methods for the analysis of survival data with censoring. This review desc...
BibTeX reference
We explore the role of the discount on closed-end funds (CEFD) in asset pricing and weakly tests its validity as a proxy for sentiment in the Canadian stock ...
BibTeX referencePricing Interest Rate Derivatives With Multilinear Interpolations and Transition Densities
This paper provides a general procedure for pricing American- and European-style interest rate derivatives within multifactor affine term structure models....
BibTeX reference
The risk-adjusted selection and timing performance (alphas and gammas) of a comprehensive and survivorship-free sample of Canadian equity SRI funds after (be...
BibTeX referencePricing the CBOT T-Bonds Futures
The aim of this paper is to investigate the pricing of the Chicago Board of Trade Treasury-Bond futures. The difficulty to price it arises from its multiple ...
BibTeX reference
Discrete-time survival data with time-varying covariates are often encountered in practice. One such example is bankruptcy studies where the status of each f...
BibTeX reference
The main purpose of this paper is to apply the True Notional Bond System (TNBS) proposed by Oviedo (2006) for the theoretical pricing of the Chicago Board ...
BibTeX referenceDiscrete-Time Survival Trees
Tree-based methods are frequently used in studies with censored survival time. Their structure and ease of interpretability make them useful to identify p...
BibTeX reference
In this paper, we develop an efficient algorithm to price options under discrete time GARCH processes. We propose a procedure based on dynamic programming c...
BibTeX reference
We propose a general setting for pricing single-name knock-out credit derivatives. Examples include Credit Default Swaps (CDS), European and Bermudan CDS op...
BibTeX reference
Installment options are a generalization of compound options, where the holder periodically decides whether to keep an option alive or not by paying the ins...
BibTeX reference
We propose a Dynamic Programming (DP) approach combined with approximation for pricing options embedded in bonds, the focus being on call and put options wit...
BibTeX reference
Several methods for reducing the variance in the context of Monte Carlo simulation are based on correlation induction. This includes antithetic variates, L...
BibTeX reference
Installment options are Bermudan-style options where the holder periodically decides whether to exercise or not and then to keep the option alive or not (by ...
BibTeX reference
Call and put options embedded in bonds are of American-style, and cannot be priced in a closed-form. In this paper, we formulate the problem of pricing thes...
BibTeX reference
Pricing Asian options based on the arithmetic average, under the Black and Scholes model, involves estimating an integral (a mathematical expectation) for w...

A hedger of a contingent claim may decide to partially replicate on some states of nature and not on the others: A partial hedge initially costs less than a...
