We propose using Realized GARCH-type models to estimate the daily price volatility in the EPEX power markets. The model specifications extract the volatility-related information from realized measures, which improves the in-sample fit of the data. More importantly, evidence on the out-of-sample...

We analyse the time series properties of the S&P500 dividend--price ratio in the light of long-memory, structural breaks and rational bubbles.
