This paper extends previous studies by investigating the relevance of structural breaks and long memory in modeling and forecasting the conditional volatility of oil spot and futures prices using a variety of GARCH-type models. Our results can be summarized as follows. First, we provide evidence...

This paper investigates whether structural breaks and long memory are relevant features in modeling and forecasting the conditional volatility of oil spot and futures prices using three GARCH-type models, i.e., linear GARCH, GARCH with structural breaks and FIGARCH. By relying on a modified...

Macroeconomic time series often involve a threshold effect in their ARMA representation, and exhibit long memory features. In this paper we introduce a new class of threshold ARFIMA models to account for this. The threshold effect is introduced in the autoregressive and/or the fractional...

This paper implements a simulation-based method for estimating the parameters of Threshold Integrated Moving Average Models with contemporaneous asymmetry. Among many simulation-based methods we use the Indirect Inference method (II) with an autoregressive model as auxiliary model. To...

This paper investigates the return links and volatility transmission between oil and stock markets in the Gulf Cooperation Council (GCC) countries over the period 2005-2010. We employ a recent generalized VAR-GARCH approach which allows for transmissions in return and volatility. In addition, we...

This article estimates and evaluates different measures of core inflation for India by employing statistical and econometric approaches. We estimate Wholesale Price Index (WPI) ex-food, WPI ex-food and energy, 20% asymmetric trimmed mean, 63rd percentile and Structural Vector Autoregression...

This paper estimates forward-looking monetary policy rules to examine the interest rate setting behavior of the State Bank of Pakistan. Considering the external constraints on monetary policy, core inflation and a country-specific measure of the output gap, we demonstrate that the State Bank of...

This paper deals with statistics�and econometrics�properties of fractionally integra- ted GARCH (FIGARCH). We compare these characteristics with those of traditional models. We insist on the GARCH exponential/IGARCH in�nite decrease of volatility impact. Then, we apply it on three Tunisian...

This article contributes to the related literature by empirically investigating the efficiency of nine energy and precious metal markets over the last decades, employing several pronounced models. We test for both short- and the long-run efficiency using, in addition to linear cointegration...

Considering nonlinearities in the exchange rate pass-through to domestic prices, this paper estimates exchange rate pass-through in Mexico. We examine responses of domestic prices to a positive one unit exchange rate shock by estimating a threshold vector autoregression (TVAR) model. A monthly...
