It derives closed-form results for the pricing of corporate securities and guarantee costs, for the pricing and timing of the option to invest and for an optimal bond coupon. By numerical analysis, It is shown that a growth of the fixed annual payment to the insurer will accelerate investment and reduce the amount of debt. A higher project volatility leads to a later investment. However, the volatility has two opposite impacts on the amount of debt and the fraction of equity allocated to an insurer and both of them are a concave function of the volatility. Key words: a mixed guarantee; real options; investment and financing policies 1 引引引 言言言 据国家发改
