Among the most popular techniques for portfolio insurance strategies that are used nowadays, the so-called \Constant Proportion Portfolio In- surance" (CPPI) allocation simply consists in reallocating the risky part of a portfolio according to the market conditions. This general method crucially...

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...

This paper assesses the impact of oil prices on economic growth of the four major OPEC countries (United Arab Emirates, Kuwait, Saudi Arabia and Venezuela) over the period spanning from 03/09/2000 to 03/12/2010. We aim at complementing the results from existing analyses (mainly focused on...

In this paper we examine the degree of interdependence between oil prices and four major countries (United

In this paper, we review the extant mathematical and environmental economics literatures on the stochastic properties of CO2 emission allowance futures prices. We explain the main findings arising from this literature from both continuous- and jump-diffusion models. Based on the Activity...

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...

This paper proposes a new class of semiparametric generalized long memory model with FIA- PARCH errors (SEMIGARMA-FIAPARCH model) that extends the conventionnel GARMA model to incorporate nonlinear deterministic trend, in the mean equation, and to allow for time varying volatility, in the...

As both speculative and hedging financial flows into commodity futures are expected to link commodity price formation more strongly to equity indices, we investigate whether these processes also create increased correlation amongst the commodities themselves. Considering U.S. oil and gas...

We combine the global Hurst exponent and Morlet wavelet multi-resolution analysis to investigate the dynamic behavior of six selected stock markets in the Mediterranean region. Specifically, we employ the resonance coefficients and their power spectra to identify potential extreme movements and...
