Expected Shortfall and It’s Application in Credit Risk Measurement
We study the credit risks of corporate debts using the coherent risk measure of ES(expected shortfall). Under our model,the firms’ value and their volatilities are the solutions of nonlinear equations. We solve the equations by the Newton-Raphson method. With the solutions,we can get the distribution of the firms’ future value. Then we estimate the ES using the Richardson extrapolation method. Compared with the firms’ repayment capability indicators,the risks measured by ES is consist with the real behavior of the firms. This shows the ES measure is effective.
