This paper investigates the responses of market interest rates to US monetary policy announcements for the US and two emerging economies, Hong Kong and Singapore which are similar on many respects but have experienced opposite exchange rate regimes in the last twenty years. Our results, based on market expectations extracted from federal fund futures rates, document that FOMC announcements significantly affect the term structure of interest rate in the US and both Asian countries. Further, international interest rate differentials around FOMC meeting dates tend to be negative for short maturities with the impact gradually dissipating as bond maturity increases. Finally, for the case of Singapore, we find that domestic interest rates react to both external and domestic monetary policy announcements with a magnitude that is larger over the full bond maturity spectrum for domestic announcements. These results are robust to time-varying futures risk premia and alternative measures of interest rates expectations. 相似文献

We examine the presence or absence of asymmetric volatility in the exchange rates of Australian dollar (AUD), Euro (EUR), British pound (GBP) and Japanese yen (JPY), all against US dollar. Our investigation is based on a variant of the heterogeneous autoregressive realized volatility model, using daily realized variance and return series from 1996 to 2004. We find that a depreciation against USD leads to significantly greater volatility than an appreciation for AUD and GBP, whereas the opposite is true for JPY. Relative to volatility on days following a positive one-standard-deviation return, volatility on days following a negative one-standard-deviation return is higher by 6.6% for AUD, 6.1% for GBP, and 21.2% for JPY. The realized volatility of EUR appears to be symmetric. These results are robust to the removal of jump component from realized volatility and the sub-samplings defined by structural-changes. The asymmetry in AUD, GBP and JPY appears to be embedded in the continuous component of realized volatility rather than the jump component. 相似文献

尽管在旅游线路的设计过程中需要解决的问题很多,但从优化的角度而言,如何设计出一条能实现出发地与目的地间的最短路径目标,便是其中的最为关键性的一个问题。由于不同的交通方式的不同组合能对应着不同的路程、时间与成本问题,因而,如何通过有效的选择来形成最佳的旅游线路也就有了相当的必要性。此外,在旅游线路设计与安排过程中,旅行社除了要合理安排和规划旅游线路的长度以力求不走回头路、不走冤枉路和形成有效的闭合回路外,还需充分考虑到其中的线路在时间安排上的合理问题;否则,再好的线路安排也会失去其内在的价值与影响力。 相似文献

In the presented text the authors judge the importance of statistics in the monetary policy of the Czech National Bank (CNB) over the course of the economic transformation process, with particular consideration of changing statistical needs and the possibilities and limits of statistical data exploitation in the monetary analyses. The importance of statistics lies on the level of collection and processing of statistical information and on the level of use of statistical methods to analyse data. Since the start of the 1990s the requirements for statistics were significantly influenced by monetary policy. In the period 1990–1997, monetary targeting was the primary influential factor. Since 1998, the monetary policy is influenced by inflation targeting. Statistical priorities switched from monetary data to economy and financial market data. Much progress has been made in the use of statistical methods for analysing data. Statistics available at present cover the CNB's standard monetary-policy requirements and are on par with those in developed countries. Its further development will reflect the standard changes taking place in the more advanced countries. 相似文献

Technological proximity and the choice of cooperation partner 总被引:1,自引:0,他引:1
This paper provides empirical tests of hypotheses of cooperative behavior provided by evolutionary approaches in the resource-based
view of the firm. The influences of “technological proximity”, individual incentives to cooperate and managerial tools to
the choice of research partner are analyzed. Using German patent data we can show the positive influence of those three determinants.
The results of this paper confirm theories dealing with the path-dependency of research activities.
