Abstract :
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.
