The theory of optimal currency areas states that a single currency zone should have symmetry of shocks and structures across regions. Research on monetary union in Europe has either assumed these conditions to hold close enough not to cause problems, or has focussed on asymmetries in shocks. But...

Conventional wisdom has it that increasing price or exchange rate uncertainty will depress investment. Using the Dixit-Pindyck model, we find that there are situations where this does happen; and situations where it does not – i.e. increasing uncertainty leads to more investment. It depends...

Shocks to bank lending, risk-taking and securitization activities that are orthogonal to real economy and monetary policy innovations account for more than 30 percent of U.S. output variation. The dynamic effects, however, depend on the type of shock. Expansionary securitization shocks lead to a...

This Paper uses a simple VAR for the industrialized world (aggregate of 17 countries), the US and the euro area to analyse the underlying shocks of the recent slowdown, i.e. supply, demand, monetary policy and oil price shocks. The results of two identification strategies are compared. One is...

I estimate the dynamic effects of respectively traditional interest rate innovations and unconventional monetary policy actions on the Euro area economy. The results show that the Eurosystem can stimulate the economy beyond the policy rate by increasing the size of its balance sheet. The...

The size and economic relevance of Europe may imply a new role for the EURO in the international financial markets. But will the EURO compete with the $US and the Yen for a place in the basket of international currencies? Will that induce a bipolar or indeed tri-polar system, and with what...

This paper analyses four popular themes in the debate about the transition to monetary union: (a) fiscal discipline creating gains in credibility; (b) there being perceptible risk of a bail out for the highly indebted countries; (c) budgets being successfully cut to the required 3% limit in...

The main obstacles to coordinating policies in practice are uncertainty about the correct model to use for policy design, and uncertainty about external variables. This paper examines the former problem. Numerical calculations using ten models from the recent Brookings Multicountry comparison...

Empirical fiscal policy reaction functions based on ex-post data cannot be said to describe fiscal policymakers intentions because they utilise data which did not exist when their decisions were made. A characterisation of what fiscal policy makers were trying to do requires real time data. This...

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,...
