老师您好,我不太理解这句话:Economic model described in this section is based on the assumption that in the long run, the real exchange rate will converge to its “fair value,” but short- to medium-term factors will shape the convergence path to this “equilibrium.“ 为什么中短期converge to equilibrium,和fair value 有什么不同?十分感谢。
已回答老师您好,我想请问一下60页:Diversification Considerations: Many investment practitioners believe that in the long run, adding unhedged foreign-currency exposure to a portfolio does not affect expected long-run portfolio returns; hence in the long run, it would not matter if the portfolio was “hedged. ”我查了一下书,这句话跟书是一样的。我觉得讲义和书是不是写错了。这句话的最后一个单词应该是unhedged的吧?
衍生品,reading39 定价和估值-swap-利率互换,收固支浮,老师刚才写的公式推导中,t=9时有两笔现金流:f4和par(1)没问题;t=6时没看懂,为什么只有f3和1,f4去哪里了?说是在1里面,为什么?
