The Predictive Ability of Several Models of Exchange Rate Volatility
West, Kenneth D.; Cho, Dongchul - 2021
We compare the out-of-sample forecasting performance of univariate homoskedastic, GARCH, autoregressive and nonparametric models for conditional variances, using five bilateral weekly exchange rates for the dollar, 1973-1989. For a one week horizon, GARCH models tend to make slightly more...

Answering the Critics : Yes, Arch Models Do Provide Good Volatility Forecasts
Andersen, Torben G. - 2008
Volatility permeates modern financial theories and decision making processes. As such, accurate measures and good … forecasts of future volatility are critical for the implementation and evaluation of asset pricing theories. In response to this …, a voluminous literature has emerged for modeling the temporal dependencies in financial market volatility at the daily …

Semiparametric detection of changes in long range dependence
Iacone, Fabrizio; Lazarová, Stěpána - 2017
We consider changes in the degree of persistence of a process when the degree of persistence is characterized as the order of integration of a strongly dependent process. To avoid the risk of incorrectly specifing the data generating process we employ local Whittle estimates which uses only...

Integrated ARCH, FIGARCH and AR models : origins of long memory
Giraitis, Liudas; Surgailis, Donatas; Škarnulis, Andrius - 2015
Although the properties of the ARCH(∞) model are well investigated, the existence of long memory FIGARCH and IARCH solution was not established in the literature. These two popular ARCH type models which are widely used in applied literature, were causing theoretical controversy because of the...

Kang, Qiang - 2002
We model the conditional mean and volatility of stock returns as a latent vector autoregressive (VAR) process to study … although the conditional correlation between the mean and volatility is negative, the unconditional correlation is positive due …
