同学你好, discount rate 有3个 distinct components
1. real risk free rate
2. expected inflation
3. 其他所有风险加总的risk premium
这里点1说反了, 如果是additional return required by investors from investing in a real default-free investment for investing in a nominal default-free investment.就对了, 因为是nominal 相比 real 多一个expected inflation.
点2是对的,因为inflation-linked bond就说明本金和CPI挂钩,也就是定价时不考虑expected inflation, 也就代表了real risk free rate.
点3只讲了liquidity premium, 还有其他的risk premium, 不全面。
