On the dynamic linkages between CO2 emissions, energy consumption and growth in Greece

This paper attempts to analyze the short-and long-run causal dynamic interactions between energy consumption, CO2 emissions and economic growth in Greece, using time-series techniques. To this end, annual data covering the period 1980-2012 are employed and tests for unit roots, the ARDL-bounds approach of cointegration, and Granger-causality based on error-correction models are applied. The results reveal strong feedback in the long-run between all the examined variables. For the shortrun, there is evidence of two-way causality in all examined pairs with only exception the direction CO2 towards GDP.peer-reviewe

Asymmetric Dependence in International Currency Markets

We find new channels for the transmission of shocks in international currencies, by developing a model in which shock propagations evolve from domestic stock markets, liquidity, credit risk and growth channels. We employ symmetric and asymmetric copulas to quantify joint downside risks and document that asset classes tend to experience concurrent extreme shocks. The time-varying spillover intensities cause a significant increase in cross-asset linkages during periods of high volatility, which is over and above any expected economic fundamentals, providing strong evidence of asymmetric investor induced contagion. The critical role of the credit crisis is amplified, as the beginning of an important reassessment of emerging currencies which lead to changes in the dependence structure, a revaluation and recalibration of their risk characteristics. By modelling tail risks, we also find patterns consistent with the domino effect
