Available in PDF, EPUB and Kindle. Book excerpt: Financial time series like exchange rates are highly persistent. An unexpected shock to the underlying variable has long lasting effects. The persistence in the volatility of the time series is usually exemplified by a highly persistent fitted GARCH model. Traditional stationary ARMA processes often cannot capture the high degree of persistence in financial time series. In the last few years, more applications have evolved using long memory processes, which lie halfway between traditional stationary I (0) processes and the non-stationary I (1) processes. There is substantial evidence that long memory processes can provide a good description of many highly persistent financial time series. This study examines last 37 years of continuous log returns of INR-USD exchange rates for long memory effect. R/S test statists confirms the presence of long memory effect, parameters are estimated using Whittle's method. Further analysis shows that only long memory component with fractionally integrated FARIMA is not stable and short memory component are required to make makes model stable. Tests prove that FARIMA (2, 0.004, 0) explains the variations best in case of Rupee-Dollar exchange rate returns.

Available in PDF, EPUB and Kindle. Book excerpt: Many authors have investigated the possibility of long memory in asset returns. Generally, very little evidence has been found for long memory in either stock returns or exchange rate returns. This paper applies the log-periodogram regression to a wide range of emerging market stock returns and finds some evidence for positive long memory in 7 of the 17 series considered.

Download or read book Large Sample Inference For Long Memory Processes written by Donatas Surgailis and published by World Scientific Publishing Company. This book was released on 2012-04-27 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: Box and Jenkins (1970) made the idea of obtaining a stationary time series by differencing the given, possibly nonstationary, time series popular. Numerous time series in economics are found to have this property. Subsequently, Granger and Joyeux (1980) and Hosking (1981) found examples of time series whose fractional difference becomes a short memory process, in particular, a white noise, while the initial series has unbounded spectral density at the origin, i.e. exhibits long memory.Further examples of data following long memory were found in hydrology and in network traffic data while in finance the phenomenon of strong dependence was established by dramatic empirical success of long memory processes in modeling the volatility of the asset prices and power transforms of stock market returns.At present there is a need for a text from where an interested reader can methodically learn about some basic asymptotic theory and techniques found useful in the analysis of statistical inference procedures for long memory processes. This text makes an attempt in this direction. The authors provide in a concise style a text at the graduate level summarizing theoretical developments both for short and long memory processes and their applications to statistics. The book also contains some real data applications and mentions some unsolved inference problems for interested researchers in the field./a

Available in PDF, EPUB and Kindle. Book excerpt: There has been recent evidence for long memory in the changes of foreign exchange spot rates that is captured by the fractionally integrated ARMA model. This paper extends these investigations in several directions. First, the estimation procedure allows for GARCH errors. Second, in addition to the total period from 1973 to 1990 three subperiods are analyzed. Third, for the US-Dollar spot rates of the Deutsche Mark and the Swiss Franc ARFIMA model selection and estimation results for various observation frequencies are compared to ARFIMA specifications and their parameter values that are obtained from temporal aggregation. As a result the evidence for weak long memory in the changes of US-Dollar exchange rates is confirmed. However, long memory appears to be a property attached to the US currency since the analysis of the Deutsche Mark/Swiss Franc spot rate changes does not reveal any long memory.
Download or read book Effects of Financial Crises on the Long Memory Volatility Dependency of Foreign Exchange Rates written by Young Wook Han and published by . This book was released on 2016 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the effects of financial crises on the long memory volatility dependency of daily exchange returns focusing on the Asian crisis in 97-98 and the Global crisis in 08-09. By using the daily KRW-USD and JPY-USD exchange rates which have different trading regions and volumes, this paper first applies both the parametric FIGARCH model and the semi-parametric Local Whittle method to estimate the long memory volatility dependency of the daily returns and the temporally aggregated returns of the two exchange rates. Then it compares the effects of the two financial crises on the long memory volatility dependency of the daily returns. The estimation results reflect that the long memory volatility dependency of the KRW-USD is generally greater than that of the JPY-USD returns and the long memory dependency of the two returns appears to be invariant to temporal aggregation. And, the two financial crises appear to affect the volatility dynamics of all the returns by inducing greater long memory dependency in the volatility process of the exchange returns, but the degree of the effects of the two crises seems to be different on the exchange rates.
Download or read book Long Memory and Volatility Dynamics in the US Dollar Exchange Rate written by Guglielmo Maria Caporale and published by . This book was released on 2016 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper focuses on nominal exchange rates, specifically the US dollar rate vis-à-vis the Euro and the Japanese Yen at a daily frequency. In the paper both absolute values of returns and squared returns are modelled using long-memory techniques, being particularly interested in volatility modelling and forecasting. Compared with previous studies using fractional integration such as Granger and Ding (1996), a more general model is estimated, which allows for dependence not only at the zero but also at other frequencies. The results show differences in the behaviour of the two series: a long-memory cyclical model and a standard I(1) model seem to be the most appropriate for the US dollar rate vis-à-vis the Euro and the Japanese Yen respectively.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We estimate FIGARCH models with data sets of daily and thirty minute returns on the Deutsche mark-US dollar exchange rate. The results point to the importance of accurately modelling the persistence properties of volatility in terms of structural breaks and long memory, and controlling for stochastic intra-daily repetitive patterns.

This book was released on 2006-04-02 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an alternative view of the workings of foreign exchange markets. The authors' modeling approach is based on the idea that agents use simple forecasting rules and switch to those rules that have been shown to be the most profitable in the past. This selection mechanism is based on trial and error and is probably the best possible strategy in an uncertain world, the authors contend. It creates a rich dynamic in the foreign exchange markets and can generate bubbles and crashes. Sensitivity to initial conditions is a pervasive force in De Grauwe and Grimaldi's model. It explains why large exchange-rate changes and volatility clustering occur. It also has important implications for understanding how the news affects the exchange rate. De Grauwe and Grimaldi conclude that news in fundamentals has an unpredictable effect on the exchange rate. Sometimes, they maintain, it alters the exchange rate considerably; at other times it has no effectwhatsoever. The authors also use their model to analyze the effects of official interventions in the foreign exchange market. They show that simple intervention rules of the "leaning-against-the-wind" variety can be effective in eliminating bubbles and crashes in the exchange rate. They further demonstrate how, quite paradoxically, by intervening in the foreign exchange market the central bank makes the market look more efficient. Clear and comprehensive, The Exchange Rate in a Behavioral Finance Framework is a must-have for analysts in foreign exchange markets as well as students of international finance and economics.
