accounting中ROE的问题
The use of debt in the firm's capital structure will increase ROE if the firm:
A.has more debt than equity.
B.pays less in taxes than in interest.
C.earns a higher return than the rate paid on debt.D.has a times interest earned greater than 1.0.
怎么用公式分析?
答
答案是C.用不着公式, 都是简单的常识.C中的return是指equity增加的比例吗？不是, 是指equity增加的绝对值（才好与the rate paid on debt作比较）
