This paper proposes a latent dynamic factor model for low- as well as high-dimensional realized covariance matrices of stock returns. The approach is based on the matrix logarithm and allows for flexible dynamic dependence patterns by combining common latent factors driven by HAR dynamics and...

Recent calculations have suggested that the German federal government has saved roughly EUR 90-100 billion, cumulatively, due to low bond yields since the onset of the Euro crisis. In order to determine the contribution of the "flight to quality" to this sum, we define the flight to quality as a...

Recent empirical evidence suggests that the variance risk premium predicts aggregate stock market returns. We demonstrate that statistical finite sample biases cannot “explain” this apparent predictability. Further corroborating the existing evidence of the U.S., we show that country...
