根據(jù)多恩布什模型,預(yù)測匯率的公式是怎么寫的?有沒有相關(guān)題?謝謝
第一題麻煩解釋下
為什么沒有persistent decline in output呢
第8題,currency portfolio是capital accont里的嗎
taylor rule中target rate不應(yīng)該考慮expected inflation嗎?為什么第三題沒有在這個(gè)基礎(chǔ)上加1.5%(inflation forecast)=3.5%?
老師,您好,在做題的時(shí)候sharpe ratio都是用globle market,ppt公式用的是資產(chǎn)i的sharpe ratio
為什么這里不基于yield curve本身是inverted來做分析呢? monetary policy寬松,短期利率下降,yield curve就會(huì)變成flatter不是steeper了
麻煩老師回答一下這道
為什么寬松的財(cái)政政策和貨幣政策會(huì)與高名義利率?雖然高通脹,但是實(shí)際利率應(yīng)該低啊。為什么實(shí)際利率和財(cái)政政策關(guān)系更緊密?寬松是高利率,緊縮是低利率?
老師,百題andrew twain第四題,數(shù)據(jù)頻率高產(chǎn)生相關(guān)性低的估計(jì)。以下題為啥是相反One bias results from the use of appraisal data in the absence of market transaction data. Appraisal values tend to be less volatile than market determined values for identical assets. As a result, measured volatilities are biased downward and correlations with other assets tend to be exaggerated.”With respect to his explanation of appraisal data bias, O’Reilly is most likely: correct. incorrect, because the measured volatilities biased upward. incorrect, because correlations with other assets tend to be understated.
請問該怎么通過current account去判斷貨幣的升值/貶值呢? 謝謝
第2題statement3為什么就不可能是invert?statement1不應(yīng)該錯(cuò)在moderately嗎?
第四題,低頻數(shù)據(jù)不是會(huì)造成平滑嗎?平滑不是相關(guān)性會(huì)降低嗎?相反高頻數(shù)據(jù)不是會(huì)相關(guān)性更高嘛?
Taloyer rule,不是 Rneutral+i expected+0.5(xxx)+0.5(XXX),第二項(xiàng)i ecpecter沒加?
第二題的C選項(xiàng),如果沒有最后半句“可提供均值的準(zhǔn)確性”,是不是就表述正確了
