问一道题:NO.PZ2016082405000067

问题如下:

Based on the following information, what are the the risk-neutral and real-world default probabilities?

•     Market price of bond is 92.

•     Liquidity premium is 1%.

•     Credit risk premium is 2%.

•     Risk-free rate is 2.5%.

•     Expected inflation is 1.5%.

•     Recovery rate is 0%.

选项:

Risk-neutral probability
Real-world probability
A.
5% 
8%
B.
8% 
5%
C.
6% 
8%
D.
5% 
6%

解释:

B The risk-neutral default probability is approximately 8% because the market price is 92% of par.

risk-neutral probability = real-world probability + credit risk premium + liquidity premium

8% = real-world probability + 2% + 1%

real-world probability = 8% - 3% = 5%

risk-neutral 是啥意思?

为啥它还等于 = real default + 流动性+风险补偿?

这是在哪里讲的啊?

同学你好!

是的,就是假设情况和现实情况差了两个premium

同学你好!

先说明一下,这道题是notes上的,很多地方不严谨,理解大意即可,不用太深究了。

1. Risk-neutral 就是风险中性,完整的计算公式可以参考讲义

这道题目中简化了计算,没有考虑 rf(实际考试的时候不建议忽略,除非选不到正确答案),认为 recovery rate = 0,所以

92 = 100 * (1-PD),得到 PD = 8%

2. risk-neutral probability = real-world probability + credit risk premium + liquidity premium

这是notes是的一张图

在真实世界里,理性的投资者是具有损失厌恶的,面对损失,会想要超过数学期望的补偿。而这个补偿premium,是credit risk 和 liquidity risk 带来的,所以得减去。

B The risk-neutrfault probability is approximately 8% because the market priis 92% of par. risk-neutrprobability = real-worlprobability + cret risk premium + liquity premium 8% = real-worlprobability + 2% + 1% real-worlprobability = 8% - 3% = 5% 这个inflation rate只是一个干扰项吧?

B The risk-neutrfault probability is approximately 8% because the market priis 92% of par. risk-neutrprobability = real-worlprobability + cret risk premium + liquity premium 8% = real-worlprobability + 2% + 1% real-worlprobability = 8% - 3% = 5% 我的只能理解,中性定价里面,所有的sprea对CR进行补偿,这个时候CR大了,所以P,如果是objective的话, sprea止对CR进行补偿,还有别的东西,所以,P对就低了。就是扫一眼知道选B , 还是不太明白你放的那个图,和这句话是怎么补偿的。讲道理RISK NATURP 1+3+2=6%,这个东西应该是sprea概念 如果套用这题,sprea 8%-2.5%=5.5%,如果是risk natur的话5.5%全部补偿CR了,再减去1%的流动性4.5%就是objective 但是这么硬算又找不到答案。。。
