Abstract

We present an exact analytic solution to the two-dimensional correlated default structural Merton model in the form of a local volatility problem using a conformal square-root transformation of the exact solution to a 2D hybrid barrier problem. We also give an approximation and evaluate it numerically to give an example. Finally we give an exact simpler solution for the zero correlation case.

Keywords: Merton, two dimensional, local volatility, hybrid barrier, approximation, correlated default, structural, conformal
