单项选择题
An analyst does research about cost of common equity. With respect to calculating the cost of equity using the bond yield plus risk premium approach, which of the following statements about the risk premium is least accurate（）
A. The risk premium compensates for the additional risk of equity compared with debt.
B. We often estimate the risk premium using historical spreads between bond yields and stock yields.
C. In developed country markets, a typical risk premium added is in the range of 2 to 4 percent.
答案
参考答案：C
解析：
risk premium=cost of equity-company bond yield，company bond yield是指公司的market yield of long-term debt，选项A和B都符合这里的风险溢价(risk premium)的定义。在发达国家，一般风险溢价所在范围为3～5个百分点，所以选项C错。
