This paper develops a model of exchange rate dynamics that takes into account positions in foreign and domestic equities in addition to “standard” short-term riskless securities. The modeling of cross-country stock holdings is motivated by evidence that a large and ever-increasing proportion...

The paper develops a financial systemic stress index (FSSI) for Greece. We present a novel methodology for constructing and evaluating a systemic stress index which i) adopts the suggestion of Hollo et al. (2012) [“CISS — A ‘Composite Indicator of Systemic Stress’ in the Financial...

We propose a new conditionally heteroskedastic factor model, the GICA-GARCH model, which combines independent component analysis (ICA) and multivariate GARCH (MGARCH) models. This model assumes that the data are generated by a set of underlying independent components (ICs) that capture the...

The estimation of multivariate GARCH time series models is a difficult task mainly due to the excessive parametrization exhibited by the problem, usually referred to as the “curse of dimensionality”. For the VEC family, the number of parameters involved in the model grows as a polynomial of...

This paper models the mean and volatility spillovers of prices within the integrated Iberian and the interconnected Spanish and French electricity markets. Using the constant (CCC) and dynamic conditional correlation (DCC) bivariate models with three different specifications of the univariate...

Previous literature has identified oil and gas prices as being the main drivers of CO2 prices in a univariate Generalized Autoregressive Conditional Heteroscedasticity (GARCH) econometric framework (Alberola et al., 2008; Oberndorfer, 2009). By contrast, we argue in this article that the...

The relationships among the Mexico EMBI+ and local and foreign risk factors are examined in this paper. The long run relationships and the dynamics are analyzed taking in account the effects of economic slowdowns into the period of the study. Also the volatilities of EMBI+, domestic interest...

We estimate and test the conditional version of an international capital asset pricing model using a parsimonious multivariate GARCH process and the multivariate nonlinear least squares method. Since our approaches are fully parametric, we can recover any quantity that is a function of the first...

In this paper, we investigate whether oil risk is priced in selected emerging markets of the Middle East region—in particular, oil-producing countries. Given that these countries have maintained fixed exchange rates against the U.S. dollar, we are able to modify the multivariate GARCH...

A major issue in both Islamic finance and conventional finance is whether the shocks to the volatilities in the asset returns are substitutes or complements in terms of taking risk. An understanding of how volatilities of and correlations between asset returns change over time including their...
