“equity-vs-bonds” premium method是什么？官網(wǎng)課后題提到的
When two currencies are pegged or linked, the bond yields of the country with the weaker currency are likely to rise higher unless the market is confident that the government will maintain the peg. 怎么理解這句話
Board member Arnold Brown asks O’Reilly about the use of high-frequency (daily) data in developing capital market expectations. O’Reilly answers, “Sometimes it is necessary to use daily data to obtain a data series of the desired length. Ironically, high-frequency data improves the precision of sample variances, covariances, and correlations but not the precision of the sample mean. High-frequency data are more sensitive to asynchronism across variables.”怎么理解關(guān)于high-frequency (daily) data 這段話？
Eastland and Northland (with currencies pegged to each other) will share the same yield curve if two conditions are met. First, unrestricted capital mobility must occur between them to ensure that risk-adjusted expected returns will be equalized. Second, the exchange rate between the currencies must be credibly fixed forever. Thus, as long as investors believe that there is no risk in the future of a possible currency appreciation or depreciation, Eastland and Northland will share the same yield curve. A shift in investors’ belief in the credibility of the fixed exchange rate will likely cause risk and yield differentials to emerge. This situation will cause the (default-free) yield curve to differ between Eastland and Northland. 這段話說的是什么意思，總結(jié)下來是三元悖論哪個不滿足？
