Abstract

We discuss the main opened questions related to credit risk, that is the default risk of a borrower. These questions concern the prediction of default (term structure of default, default correlation, recovery rate, determination of the required capital), the pricing of debts (according to risk neutral, actuarial or accounting approaches), and the construction of appropriate databases. Nous présentons les principales questions ouvertes liées au risque de crédit, c’est-à-dire au non-remboursement des dettes par un emprunteur défaillant (structure par terme de défauts, corrélation de défaut, taux de recouvrement, calcul de réserves). Ces questions concernent aussi bien la prévision des défaillances, que la valorisation des dettes (selon des approches risque neutre, comptable ou actuarielle) ou la constitution de bases de données adéquates.
