老师好，半小时前问了一个关于libor的问题，是自己糊涂了，两个libor不矛盾，问题已解决，谢谢

老师好，six-month Libor或者three-month Libor表达的是年利率还是对应期间（即6月或3月）的利率呢? 授课的两处感觉相互矛盾..不知如何理解? Reading50的课后第三题感觉是把three-month libor当一个三个月期限的利率 Reading52里求discount margin时（PPT136或书上426的公式）又将three-month libor作为年化利率，计算payment时还除以4.. 有点不太理解，麻烦老师解答了，谢谢

03.单选题 已收藏 标记 纠错 Following a sharp increase in the price of energy, the overall price level is most likely to rise in the short run: A and remain elevated indefinitely unless the central bank tightens. B but be unchanged in the long run unless the money supply is increased. C and continue to rise until all prices have increased by the same proportion. 查看解析 上一题 提交试卷 正确答案B 您的答案A本题平均正确率：64% Aggregate supply curve难度：一般 推荐：      答案解析 An increase in energy prices will shift the short-run aggregate supply curve (SRAS) to the left, reducing output and increasing prices. If there is no change in the aggregate demand curve, in particular if the central bank does not expand the money supply, slack in the economy will put downward pressure on in input prices, shifting the SRAS back to its original position. In the long run, the price level will be unchanged. 问： 1.B.货币供给量的增加具体是影响LRAS的五个种的哪一个因素，是physical capital吗？ 2.A,C选项为什么错（尤其是C，并没有涉及到长期）可以说明一下吗？讲解中没有提及。 请逐次回答 谢谢
