In the Basel regulation the required capital of a financial institution is based on conditional measures of the risk of its future equity value such as Value-at-Risk, or Expected Shortfall. In Basel 2 the uncertainty on this equity value is captured by means of changes in asset prices (market...

By introducing a structure of the balance sheets of the banks, which takes into account their bilateral exposures in terms of stocks or lendings, we get a structural model for default analysis. This model allows us to distinguish the exogenous and endogenous default dependence. We prove the...

The aim of our paper is to price credit derivatives written on a single name when this name is a bank. Indeed, due to the special structure of the balance sheet of a bank and to the interconnections with other institutions of the financial system, the standard pricing formulas do not apply and...

It is shown that backward-forward procedure which selects solutions in dynamic models with rational expectations may fail to give a solution when the lags are of order two.

The Gaussian Affine Term Structure Model (ATSM) introduced by Duffie and Kan is often used in finance to price derivatives written on interest rates or to compute the reserve to hedge a portfolio of credits (CreditVaR), and in macroeconomic applications to study the links between real activity...

The trading systems used on financial markets differ in terms of matching procedures, selected norms to write contracts, existence or not of intermediaries to ensure liquidity, market transparency... We are interested in measuring the direct effect on market specifics of a matching procedure...

The cleaning up costs after closure of chemical or nuclear plants are large. They have to be taken into account in the production costs and in the pricing of the corporate, owner of such plants. Moreover, it is necessary to create a reserve account to cover these future large and long term...

We discuss the relevance of the volatility as a risk measure. By considering recent studies on tick by tick data and specific features of derivatives, we introduce alternative measures to take into account the time and volume effects, or the distributional asymmetry.
