β of the firm 怎么理解？谢谢

问题如下：

Assume a project has 10% RAROC. The beta of the firm's equity is 1.5, the beta of the firm is 1.3. The expected market return is 8% and risk free rate is 2%. Which of the following about adjusted RAROC is correct?

选项：

We should accept the project as the adjusted RAROC is higher than the market risk premium.

We should reject the project as the adjusted RAROC is lower than the risk-free rate.

The adjusted RAROC is 10%.

The adjusted RAROC is 2.2%.

解释：

B is correct.

考点：adjusted RAROC

解析：Adjusted RAROC=10%-1.5(8%-2%)=1%. 因此CD选项错。

Adjusted RAROC应当与无风险利率作比较，1%<2%，因此拒绝该项目。
