The EMS's robustness in the face of stochastic shocks is studied, using the Liverpool World Model and the optimal strategy algorithm of Brandsma and Hughes Hallett. The EMS began life in 1979 with a system design permitting regular parity changes; we find this design to be relatively unstable,...

The effectiveness of cyclically adjusted balances (CABs) as an indicator of the health of public finances depends on the accuracy with which cyclically adjusted figures can be calculated in real time. This paper measures the accuracy of such figures using a specially constructed real time data...

Economic and monetary reunification in Germany has proved to be more expensive than previously thought - and not just for the Germans. If a `Mezzogiorno' problem of continuing fiscal transfers to the East and possible migration flows westwards are to be avoided, there must be convergence in...

We present three different models of imperfect transparency in monetary policy: political transparency, economic transparency and constructive ambiguity. The first two show that transparency reduces the variability of inflation and the output gap but does not affect their average levels. But if...

This paper distinguishes between some obvious necessary and sufficient conditions for adopting the target zone proposal as a means of improving macroeconomic performance. The necessary conditions may be satisfied fairly easily, but it is a good deal more difficult to design a targeting system...

The search for and dating of a possible european business cycle, has been inconclusive. At this stage, there is no consensus on the existence of such a cycle, or of its periodicity and amplitude, or of the relationship of individual member countries to that cycle. Yet cyclical convergence is the...

The persistence of large trade and budget imbalances has led to increasing demands for protectionist policies. Despite a substantial theoretical literature there appears to be no empirical literature on the use of tariffs as a macroeconomic policy instrument. This paper fills that gap, using the...

If private sector agents hold rational expectations, they will predict any future policy switches. Discounting the announced optimal policies, if they are not credible, will lead to a response which deprives the government of any incentive to renege on previous announcements and of the benefits...

We study the effects of Central Bank transparency on inflation and the output gap. We thus first identify a small analytical model, which concludes that transparency affects the variability of inflation and output and not their average levels. Then we examine whether this conjecture holds...

The early 1990s marked a distinction between the EMS as a vehicle for creating monetary stability and the EMS as a vehicle for moving towards monetary union. We model that distinction by contrasting policies generated by preference transfers from the lead country (to create the EMS discipline of...
