Long memory, realized volatility and HAR models
Baillie, Richard; Calonaci, Fabio; Cho, Dooyeon; Rho, … - 2019
The presence of long memory in Realized Volatility (RV) is a widespread stylized fact. The origins of long memory in RV …

Exchange Rate Returns Standardized by Realized Volatility are (Nearly) Gaussian
Andersen, Torben G. - 2000
It is well known that high-frequency asset returns are fat-tailed relative to the Gaussian distribution tails are typically reduced but not eliminated when returns are standardized by volatilities estimated from popular models such as GARCH. We consider two major dollar exchange rates, and we...

Answering the Critics : Yes, ARCH Models Do Provide Good Volatility Forecasts
Andersen, Torben G. - 1997
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 …

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...

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...

Breaks in the Phillips Curve : Evidence from Panel Data
Smith, Simon C.; Timmermann, Allan; Wright, Jonathan H. - National Bureau of Economic Research - 2023
We revisit time-variation in the Phillips curve, applying new Bayesian panel methods with breakpoints to US and European Union disaggregate data. Our approach allows us to accurately estimate both the number and timing of breaks in the Phillips curve. It further allows us to determine the...

On the Relationship Between the Conditional Mean and Volatility of Stock Returns : A Latent VAR Approach
Brandt, Michael W. - 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 …

On the economic determinants of oil production : theoretical analysis and empirical evidence for small exporting countries
Cologni, Alessandro; Manera, Matteo - 2011
In this paper, decisions regarding production in oil exporting countries are studied by means of theoretical analysis and empirical investigation. Under the assumptions of exogenous oil prices and world oil demand, we are able to describe the relationship between oil production levels and...
