We apply several recently proposed tests for structural breaks in conditional variance and covariance dynamics. The tests apply to both the class of ARCH and SV type processes and allow for long memory features. We also apply them to data-driven volatility estimators using high-frequency data...

Markets makers quote many option categories in terms of implicit volatility. In doing so, they can reactivate the Black and Scholes model which assumes that the volatility of an option underlying is constant while it is highly variable. First of all, this article, whose purpose is very...

This paper proposes an indirect inference (Gourieroux, Monfort and Renault, 1993; Smith, 1993) estimation method for a large class of dynamic equilibrium models. Our approach is based on the observation that the econometric structure of these systems naturally generates auxiliary equilibria that can...

Les taux de défaut sont des séries couramment utilisées dans les simulations de crise. Au Canada comme dans beaucoup d'autres pays, on ne dispose pas de séries rétrospectives relatives aux taux de défaut sectoriels sur les prêts bancaires aux entreprises. La connaissance de ces taux est...

Default rates are series commonly used in stress testing. In Canada, as in many other countries, there are no historical series available for sectoral default rates on bank loans to firms. Knowledge of such data is required to assess the impact of shocks on the balance sheets of financial...

French Abstract: Le risque de défaut est le grand oublié de l'évaluation des actions. Nous démontrons dans cet article que son effet sur la valeur est pourtant plus important pour une action que pour une obligation.Pour ce faire nous nous basons sur un modèle à fonction d'intensité de...

Pour une entreprise, le maintien d’une croissance soutenue pendant une longue période est délicat. Il suppose, outre des conditions de marché favorables, un pilotage du rythme de développement adapté aux contraintes financières.

English Abstract: In this article we discuss the impact of financial debt on shareholder value using a new approach that aims: i) to explain the effect that leverage from debt has on a stock's systematic risk, or what we shall call here “the systematic cost of leverage,” and ii) to account...

The recent financial crisis raised awareness of the need for a framework for conducting macroprudential policy. Identifying as early as possible and addressing the buildup of endogenous imbalances, exogenous shocks, and contagion from financial markets, market infrastructures, and financial...
