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...

We provide comprehensive evidence of return and volatility spillovers for the four major agricultural commodi- ties including sugar, wheat, corn and cotton over the recent period 2003-2010. Our results from the recent VAR- GARCH model of Ling and McAleer (2003) that allows for simultaneous shock...

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...

We investigate the potential of structural changes and long memory (LM) properties in returns and volatility of the four major precious metal commodities traded on the COMEX markets (gold, silver, platinum and palladium). Broadly speaking, a random variable is said to exhibit long memory...

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 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...

This paper analyses the descriptive power of the different extensions of the Taylor rule. It also investigates whether monetary policy in South Africa can indeed be described by a linear Taylor rule or, instead, by a nonlinear rule. In particular, we extend the linear Taylor rule to a...

In this paper we make use of several multivariate GARCH models (CCC-, DCC-, BEKK-, diagonal BEKK-, and VAR-GARCH) to investigate both return and volatility spillovers between world gold prices and stock market in China over the period from March 22, 2004 through March 31, 2011. We also analyze...

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...
