This article presents a robust augmented Kalman filter that extends the data – cleaning filter (Masreliez and Martin, 1977) to the general state space model featuring nonstationary and regression effects. The robust filter shrinks the observations towards their one-step-ahead prediction based...

A novel dynamic asset-allocation approach is proposed where portfolios as well as portfolio strategies are updated at every decision period based on their past performance. For modeling, a general class of models is specified that combines a dynamic factor and a vector autoregressive model and...

This article assesses the impact of unconventional monetary policies and sheds light on their transmission mechanism in the United States. Using a three-variable Markov switching factor-augmented vector autoregression (MS-FAVAR) with time-varying transition probabilities and a shadow short-term...
