| Summary: | 碩士 === 國立政治大學 === 金融學系 === 89 === Based on Merton(1974) and Leland(1994), we construct a continuous- time capital structure model with subordinated debt. Quantitative results may serve the guidance of financial policy of the firm. Both endogenous bankruptcy and risk shifting behaviors are the agency problems between the equityholders and debtholders. Based on our model, the agency problems is considered and the agency costs are calculated. From the result of simulation, endogenous bankruptcy agency cost is small but sensitive to the volatility of unlevered asset value of the firm. Under renegotiation-proof, the senior debt is harmed by the issuance of the subordinated debt in our model. The risk premium of the subordinate debt is higher than that of the senior debt is confirmed by the model, however, when the firm is near bankruptcy, the behavior of "high risk high return" of both debts is reversed. The reason for the junk bond behavior may be explained as the negative effect of risk premiums due to the increase of the probability of bankruptcy is higher than the positive effect of the greater risk caused by higher volatility.
