This paper explores the relevance of asymmetry and long memory in modeling and forecasting the conditional volatility and market risk of four major commodities (crude oil, natural gas, gold, and sil- ver). A broad set of the most popular linear and nonlinear GARCH-type models is used to...

This paper explores the relevance of asymmetry and long memory in modeling and forecasting the conditional volatility and market risk of four widely traded commodities (crude oil, natural gas, gold, and silver). A broad set of the most popular linear and

We study performance of Islamic and conventional indices of the Gulf Cooperation Council (GCC) countries in the wake of financial crisis of 2008 and test whether Islamic indices were less risky than conventional indices. We make use of data of the six GCC markets as well as the Dow Jones Islamic...

This paper proposes to investigate the impact of ?nancialization on energy markets (oil, gas, coal, and electricity European forward prices) during both normal times and periods of extreme ?uctuation through an original behavioral and emotional approach. With this aim, we propose a new...

This paper constructs a robust optimization framework of the uncertain worst-case return. The model defines an adjustable discrete uncertainty set which controls the conservatism of the optimal asset allocation. Without prior assumptions on the data generating process, the model also develops an...

The aim of this research is to examine the structural changes of European carbon futures price under the European Union Emissions Trading Scheme (EU ETS) during 2005-2012. More speci fically, by relying on the daily EU allowance (EUA) futures contract, we investigate the structural changes of...

We empirically reinvestigate the issue of excess comovement of commodity prices initially raised in Pindyck and Rotemberg (1990) and show that excess comovement, when it exists, can be related to hedging pressure and speculative intensity in commodity futures markets. Excess comovement appears...

Two integrated financial markets are generally subjected to common shocks revealing that commonalities in funda- mentals drive the underlying return processes. In such a case, volatilities should share a long-run component although their transitory

The aim of this paper is to study the degree of interdependence between oil price and stock market index into two groups of countries: oil-importer countries and exporter ones. To this end, we propose a new empirical methodology allowing a time-varying dynamic correlation measure between the...
