这道题是考察 Equity and equity risk premium. 何老师说过一个结论：Equities are a bad hedge for bad consumption outcomes，因为 equity risk premium 和经济周期的波动正相关，而消费也是和经济周期正相关，因此，equity risk premium 和 consumption outcomes 正相关。不用被题目说什么demanding large equity risk premium 迷惑，你看到equity risk premium，又看到 consumption outcomes 直接就应该想到课上何老师说的结论了。
NO.PZ2015121810000042 问题如下 Risk-averse investors manng a large equity risk premium are most likely expecting their future consumption outcomes anequity returns to be: A.uncorrelate B.positively correlate C.negatively correlate B is correct.If investors manhigh equity risk premiums, they are likely expecting their future consumption anequity returns to positively correlate The positive correlation incates thequities will exhibit poor heing properties, equity returns will high (e.g., poff) ring \"gootimes\" anwill low (e.g., not poff) ring \"btimes\". In other wor, the covarianbetween risk-averse investors’ inter-temporrates of substitution anthe expectefuture prices of equities is highly negative, resulting in a positive anlarge equity risk premium. This is the case because, in gootimes, when equity returns are high, the marginvalue of consumption is low. Similarly, in btimes, when equity returns are low, the marginvalue of consumption is high. Holng all else constant, the larger the magnitu of the negative covarianterm, the larger the risk premium. 考点 equity risk premium consumption outcomes解析问的是股票收益与实体经济的相关性，两者是正相关的，因为实体经济变好，股票收益率增加。正因为两者正相关，所以在经济下滑时，股票不是很好的对冲经济下滑的工具，所以要使风险厌恶的投资者投资股票，就必须给他们更高的风险补偿。 future consumption outcome = marginvalue of consumption?

NO.PZ2015121810000042 我想的是未来经济差，风险就高，所以要求的对风险的补偿就高，经济和风险补偿之间就是反比关系。但是这里问的是equity return，equity return是指Pt+1-Pt，这个是跟risk premium是反比是么？ 所以答案是反向关系。我这么理解对吗？
NO.PZ2015121810000042 老师这道题的答案很绕，请问future consumption outcomes到底是什么，是marginutility of future吗？如果是的话，那根据何老师讲的，回报率越高导致未来的utility下降，这个应该是负相关的关系。如果不是的话，那future consumption outcomes到底是什么？？
