可以再解释一下A和C吗 没理解

问题如下:

The carbon risk premium is best described as a:

选项:

A.higher price consumers pay for carbon-neutral products.

B.higher return required for investments in high-carbon companies.

C.discount applied to risky company cash flows when valuing green bonds.

解释:

B is correct because a carbon risk premium is said to exist when investors require a higher compensation for the perceived risk from investing in high-carbon companies. Several studies have argued that companies with higher (absolute levels of or relative increases in) CO2 emissions are associated with higher returns; however, studies have also found evidence for the converse—a positive link between reductions in carbon footprint and improvements returns.

嗨,努力学习的PZer你好:


碳溢价是因为高碳产品本身带来的,由于承担了更多的碳污染的风险而要求的额外收益,因此,碳溢价本身与高风险相对的,自然而然,如果是估值的话,折现率会变高。


请参考第三章水印版133页案例和后面关于折现率知识的补充。


折现率的定义

折现率(Discount Rate)是金融和经济学中的一个重要概念,表示未来现金流的现值与其未来值之间的折扣。简单来说,折现率用于将未来的金额转换为现在的价值。折现率越高,未来现金流的现值越低;折现率越低,未来现金流的现值越高。

折现率通常用于以下场景:

投资项目评估:用于计算项目的净现值(NPV),帮助投资者判断项目的可行性。

债券定价:用于确定债券的现值和收益率。

公司估值:用于评估公司的未来现金流和确定其现值。

折现率的计算公式

折现率用于计算未来价值的现值,常见的公式是:

其中:

 PV 是现值(Present Value)

FV 是未来值(Future Value)

r是折现率(Discount Rate)

n是时间段(通常以年为单位)

影响折现率的因素

影响折现率大小的核心取决于投资的风险水平,风险越高,折现率越大;风险越低,这效率越小。折现率的组成部分包括:

无风险利率

 投资风险溢价
