In this paper, we present a general discrete-time affine framework aimed at jointly modeling yield curves associated with different debtors. The underlying fixed-income securities may differ in terms of credit quality and/or in terms of liquidity. The risk factors follow conditionally Gaussian...

This article proposes an overview of the usefulness of the regime switching approach for building various kinds of bond pricing models and of the roles played by the regimes in these models. Both default-free and defaultable bonds are considered. The regimes can be used to capture stochastic...

The recent macro-finance literature does not agree either about the empirical properties of the expectation part and of the term premium on long-term bonds or about the importance or even the direction of the relationship between the term premium and future economic activity. This paper proposes...

This doctoral thesis develops regime-switching models of the term structure of interest rates. A general framework is proposed to model the joint dynamics of yield curves associated with different debtors (Chapter 2). This framework is exploited to analyse the fluctuations of ten euro-area...

The recent macro-finance yield curve literature has focused on the extraction of a reliable measure of term premia (on long-term bonds) and on their relevant relationship with future economic activity (GDP), because of the practical implications of this relationship for the conduct of the...

We define a disastrous default as the default of a systemic entity. Such an event is expected to have a negative effect on the economy and to be contagious. Bringing macroeconomic structure to a noarbitrage asset-pricing framework, we exploit prices of disaster-exposed assets (credit and equity...

We build an Affine Term Structure Model that provides non-negative yields at any maturity and that is able to accommodate a short-term rate that stays at the zero lower bound (ZLB) for extended periods of time while longer-term rates feature high volatilities. We introduce these features through...

In this paper, we propose a quadratic term-structure model of the EURIBOR-OIS spreads. As opposed to OIS, EURIBOR rates incorporate credit and liquidity risks. Indeed, a bank that lends on the unsecured market requires compensations for facing (a) the risk of default of the borrowing bank and...
