A common argument against monetary union is that it precludes stabilization of economies through monetary and exchange rate policy. The authors address this point by calculating the relative empirical importance of industry-specific, country-specific, and aggregate disturbances using a...

We analyse empirically the effect of uncertainty on the investment decisions of a sample of quoted German firms. The uncertainty measures are constructed by employing two procedures: the conventional formula of standard deviation, and the GARCH methodology. In the econometric estimates the...

UK regional data on GDP and the GDP deflator are analysed to extract information on underlying demand and supply shocks as well as aggregate demand and supply shocks. Identification is achieved using long run restrictions, based on a theoretical model. The main results are that the supply shocks...

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 inflation are estimated in dynamic linear models using the Kalman filter. We compare...

This paper tests the properties of the zloty-dollar exchange rate for the possible presence of unknown non-linearities. It concludes that there is strong evidence for the presence of an underlying non-linear process which is possibly chaotic. A non-linear model which allows for discrete...
