Reading 27 官方教材 Q9：烦请解释答案中最后两句话 （1）the short term interest rate, however, overstates the long term expected inflation：首先题干中的前提"current interest rate environment"对应case情景描述的哪个部分？其次，利率怎么影响通货膨胀的？ (2）Using the short-term interest rate, estimates of the long term required return on equity will be biased upwards：若根据题干，RoE 是（短期国债，历史ERP）的函数，ROE的估值为什么会受到利率的影响？

The author of a new textbook received a $100,000 advance from the publisher this year. $40,000 of income taxes were paid on the advance when received. The textbook will not be finished until next year. Determine the tax basis of the advance at the end of this year. A $0. B $40,000. C $100,000. 查看解析 上一题 下一题 正确答案A 您的答案A本题平均正确率：46% DTA & DTL难度：一般 推荐：      答案解析 For revenue received in advance, the tax base is equal to the carrying value minus any amounts that will not be taxed in the future. Since the advance has already been taxed, $100,000 will not be taxed in the future. Thus, the textbook advance liability has a tax base of $0 ($100,000 carrying value - $100,000 revenue not taxed in the future). 请问：这里涉及到tax base的公式吗？洪老师视频里没有讲到有关税基的计算，可否公式化说明

Reading 27 官方教材 Q8：不理解这道题目的答案逻辑。我的理解是Disruptive events of 2004 to 2006 会令市场在这期间对股价的要求回报率上升，因为ERP上升（由于国家风险溢价，外汇spread）。但长期来看，ERP normalised以后可能会降低，所以historical ERP是 biased upwards. 哪里错了？谢谢。
