Exploiting information contained in the term-structure of sovereign credit spreads, we estimate time-varying fiscal limits – defined as the maximum outstanding debt that can credibly be covered by future primary budget surpluses. Our approach is based on a novel sovereign credit risk model...

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...

This paper introduces a novel kind of interest-rate model offering simple analytical pricing formulas for swaps, futures, swaptions, caps and floors. The model is based on an original use of regime-switching features that makes it consistent with the non-linear behavior of interest rates. In...

This paper illustrates how a parsimonious macro-finance model can be exploited to investigate the frequency-domain properties of debt service implied by various financing strategies. This original approach is valuable to public debt managers seeking to assess the fiscal-hedging properties of the...

In this paper, we propose a model of the joint dynamics of euro-area sovereign yield curves. The arbitrage-free valuation framework involves five factors and two regimes, one of the latter being interpreted as a crisis regime. These common factors and regimes explain most of the fluctuations in...

This paper develops an arbitrage-free affine term structure model of potentially defaultable sovereign bonds to model a cross-section of eight euro area government bond yield curves since January 1999. The existence of a common monetary policy under European Monetary Union determines the short...

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 paper presents a no-arbitrage model of the yield curve that explicitly incorporates the central-bank policy rate. After having estimated the model using daily euro-area data, I explore the behavior of risk premia at the short end of the yield curve. These risk premia are neglected by the...
