In this paper we focus on a fundamental practical issue regarding the bilateral counterparty risk adjustment. The past literature assumes that, at the moment of the first default, a risk-free closeout amount will be used. The closeout amount is the net present value of the residual deal which is...

This paper studies the discriminatory power and calibration quality of the structural credit risk models under the 'exogenous default boundary' approach including those proposed by Longstaff and Schwartz (1995) and Collin-Dufresne and Goldstein (2001), and 'endogenous default boundary' approach...

This paper develops an empirical procedure for analyzing the impact of model misspecification and calibration errors on measures of portfolio credit risk. When applied to large simulated portfolios with realistic characteristics, this procedure reveals that violations of key assumptions of the...

This paper develops a structural model for the valuation of sovereign debt in which a sovereign country faces a strategic default decision under the risk of experiencing a banking crisis. The sovereign's default policy is governed by the trade-off between lower debt-servicing expenditures and...

This paper studies the economic and theoretical foundations of insolvency risk measurement and capital adequacy rules. We show that the keys to risk sensitivity, simplicity and comparability are symmetry, proportionality and scale invariance. We argue that a back to basics approach should be...
