In the last few years we have observed the deregulation in electricity markets and an increasing interest in price dynamics has been developed especially to consider all stylized facts shown by spot prices. Only few papers have considered the Italian Electricity Spot market since it has been...

New results are presented relating to the integration of the French, German, British, Dutch and Spanish power markets at day-ahead, week-ahead, one month-ahead and two month-ahead lead times. Overall, there is evidence of market integration, increasing over time, despite an underlying...

This paper analyses the volatility of wholesale electricity markets for five markets in Europe. Using GARCH models after filtering outliers, significant asymmetric effects and volatility persistence have been documented. Moreover, empirical evidence is provided on a significant relation between...

In this paper we suggest an extension of the forward search methodology to GARCH models which are often used for forecasting stock market volatility. It is frequently found that estimated residuals from GARCH models have excess kurtosis, even when one allows for conditional t-distributed errors....
