This paper uses Monte Carlo techniques to assess the loss in terms of forecast accuracy which is incurred when the true DGP exhibits parameter instability which is either overlooked or incorrectly modelled. We find that the loss is considerable when a FCM is estimated instead of the true TVCM,...

For the sake of credibility the ECB has to commit to a clear policy strategy - a direct inflation target or an intermediate monetary target. We offer some information on the scale of control and indicator problems associated with both strategies. We estimate the links between monetary policy...

We offer some empirical evidence on the likely scale of control and indicator problems surrounding alternative monetary targets and a direct inflation target. The links between monetary policy actions and inflationare estimated in dynamic linear models using the Kalman filter. We compare...

We investigate the asymmetric risk-return relationship in a time-varying beta CAPM. A state space model is established and estimated by the Adaptive Least Squares with Kalman foundations proposed by McCulloch. Using S&P 500 daily data from 1987:11-2003:12, we find a positive risk-return...
