老师上课时强调过，当估计要求回报率时，选取短期国债和长期国债导致无风险利率不同 会对市场风险溢价造成的影响是确定的。是对要求回报率是不确定的 因为相加2项的影响是相反的。这道题中短期利率大于长期利率 所以使用短期利率计算要求回报率的时候第一象会提高，但市场风险溢价会下降所以应该是无法确定最终要求回报率 为什么答案可以generally的判断会高估。

The requirereturn reflects the magnitu of the historicequity risk premium, whiis generally higher when baseon a short-term interest rate (a result of the normupwarsloping yielcurve), anthe current value of the rate being useto represent the risk-free rate. The short-term rate is currently higher ththe long-term rate, whiwill also increase the requirereturn estimate. The short-term interest rate, however, overstates the long-term expecteinflation rate. Using the short-term interest rate, estimates of the long-term requirereturn on equity will biaseupwar.老师你好，这题的解答中说历史的ERP曲线是向上倾斜的，请问这个是为什么？需要考虑题目中战争状态时候的ERP吗？战争状态的话ERP曲线应该是向下倾斜的吧。
NO.PZ201512300100000303 我想知道，向下调整和有一个向下的bias，在表述上是什么样的？因为我发现我有点模糊了 upwarbiasebiaseupward
