We analyze the empirical properties of the volatilityimplied in options on the 13-week US Treasury bill rate. These options havenot been studied previously. It is shown that a European style put optionon the interest rate is equivalent to a call option on a zero-coupon bond.We apply the LIBOR market model and conduct a battery of validity tests tocompare three different volatility specifications: contact, affine, and exponentialvolatility. It appears that the additional parameter in the affine and theexponential volatility function is not justified. Overall, the LIBOR marketmodel fares well in describing these options. 相似文献

Finite dimensional Markovian HJM term structure models provide ideal settings for the study of term structure dynamics and interest rate derivatives where the flexibility of the HJM framework and the tractability of Markovian models coexist. Consequently, these models became the focus of a series of papers including Carverhill (1994), Ritchken and Sankarasubramanian (1995), Bhar and Chiarella (1997), Inui and Kijima (1998), de Jong and Santa-Clara (1999), Björk and Svensson (2001) and Chiarella and Kwon (2001a). However, these models usually required the introduction of a large number of state variables which, at first sight, did not appear to have clear links to the market observed quantities, and the explicit realisations of the forward rate curve in terms of the state variables were unclear. In this paper, it is shown that the forward rate curves for these models are affine functions of the state variables, and conversely that the state variables in these models can be expressed as affine functions of a finite number of forward rates or yields. This property is useful, for example, in the estimation of model parameters. The paper also provides explicit formulae for the bond prices in terms of the state variables that generalise the formulae given in Inui and Kijima (1998), and applies the framework to obtain affine representations for a number of popular interest rate models. 相似文献

We analyze the impact of monetary policy on inflation, interest rates and exchange rates in a model with segmented asset markets developed by Grossman and Weiss (1983) and Rotemberg (1984, 1985). We find parameters for which real and nominal exchange rates in this model are (1) much more volatile than interest rates, inflation rates, and money growth rates, (2) highly correlated with each other, and (3) highly persistent. While this model fails to match the data in other important respects, it illustrates a potentially useful approach to modelling exchange rate behavior. 相似文献

金融工程具有对风险的规避和放大效应。金融工程的发展不仅需要强大的技术手段支持,更需要政府从制度层面进行合理配置。本文分析了金融工程在经济运行中的负面作用,根据当前我国利率、汇率市场化改革的宏观环境,并结合当前国外金融制度建设的基本特征和我国基本国情,提出了我国金融工程发展的制度框架。其中,近期制度建设构想为:加强法规制度建设,优化金融环境,严防金融欺诈;加强监管机构管理,确保其独立性和公平性;加强二级市场管理建设。远期制度建设构想为:进一步强化对产品发行人、合作投资计划、市场中介机构和行业自律等方面的制度约束。 相似文献

我国1999年开征的存款利息所得税是一次典型意义上的相机调控行为,短期内达到了预期的调控目标。但随着政策持续时间的延长,政策刚性对社会公平和经济长期增长的负面影响也在逐步增强。而且相机性财政政策仅仅是一项短期政策,不应该被长期实施。相机性政策的长期实施不仅会使短期的政策效应丧失,而且政策刚性产生的负面影响将会不断扩大。对利息所得税而言,如果不能将其纳入个人所得税改革的整体框架内统筹安排,则应考虑尽快退出。 相似文献

This study extends research on the day-of-the-week effect towards European real estate indices. We examine this anomaly for
several European securitized real estate index returns between 1990 and 2003. Although the countries under analysis have unique
country-specific patterns, we find that eight out of eleven European countries exhibit abnormally high Friday returns. Moreover,
two different Europe indices also exhibit the Friday anomaly. The anomaly is robust with respect to extreme observations,
alternative specifications and several well-known calendar effects. 相似文献

We consider the Merton problem of optimal portfolio choice when the traded instruments are the set of zero-coupon bonds. Working within a Markovian Heath–Jarrow–Morton model of the interest rate term structure driven by an infinite-dimensional Wiener process, we give sufficient conditions for the existence and uniqueness of an optimal trading strategy. When there is uniqueness, we provide a characterization of the optimal portfolio as a sum of mutual funds. Furthermore, we show that a Gauss–Markov random field model proposed by Kennedy [Math. Financ. 4, 247–258(1994)] can be treated in this framework, and explicitly calculate the optimal portfolio. We show that the optimal portfolio in this case can be identified with the discontinuities of a certain function of the market parameters. 相似文献

This paper provides new evidence on the impact of electronic trading on brokerage commissions by investigating a sample period that covers the period of transition from floor to electronic trading on the Sydney Futures Exchange. After controlling for liquidity, volatility and broker identity, the introduction of electronic trading remains to be associated with lower brokerage commissions relative to floor markets. The study also provides new evidence on brokerage commissions in futures markets finding that commission fees charged on futures trades average 0.002% of transaction value. This is up to 120 times smaller than the magnitude of brokerage fees charged in stock markets, and considerably lower than the magnitude of brokerage fees assumed for futures markets in previous research. Consistent with existing studies based on stock markets, commissions charged per contract decrease with order size reflecting economies of scale in the provision of brokerage services in futures markets. Commission rates are positively related to bid-ask spreads and price volatility, which proxy for the probability of execution error costs and execution difficulty, respectively. Finally, the identity of the broker is found to be a significant determinant of commissions reflecting different pricing schedules across brokers. 相似文献
