We propose to estimate heteroskedastic dynamic factor models using the Kalman filter, where the state vector is augmented with the heteroskedastic disturbances. Although this model is not conditionally Gaussian, Monte Carlo results show that parameters can be accurately estimated.

This paper answers the following questions. If the Euro foreign exchange risk is given, what is the cost of eliminating such a risk? How does risk aversion affect this cost? What is the relation between the insurance premium on the Euro and this cost? Is it possible to find out the level of risk...

In this paper, the tests of Kapetanios, Shin, and Snell (2003) and Bec, Ben Salem, and Carrasco (2004), which are designed to detect nonstationarity verses globally stationary exponential smooth transition autoregressive (ESTAR) nonlinearity, are extended to allow for a delay parameter, d, that...
