One consequence of the Great Recession that began in 2008 has been the sovereign debt crisis within the European Monetary Union (EMU) and the increasing risk premium associated with government debt of "peripheral" countries (primarily, Greece, Ireland, Portugal and Spain). Firstly, this paper analyses what macroeconomic variables are more related w...

This article focuses on the study of the leverage effect in the deregulated Spanish wholesale electricity market. For this purpose, we propose a stochastic volatility alternative, a threshold asymmetric autoregressive stochastic volatility (TA-ARSV) model over the well known AGARCH and EGARCH models. The results clearly favour the TA-ARSVA specific...

The exchange rate is a variable that economic agents have in consideration. For this reason, in this paper we suggest a decision method to compare several exchange rates.
