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...

Most of the literature on the independence of the Central Bank assumes only one policy instrument is available: monetary policy. If we introduce fiscal policy as well, when preferences may differ among policy-makers, the situation is radically different. In this case fiscal policy will weaken...

The economic recessions since 1973 have emphasised the interdependence of the major economies and their policy choices. This paper examines whether decentralised control of the world economy effectively limits our ability to manage individual economies. It is well known that noncooperative...

It is widely accepted that in order to improve the economic position of the EU relative to the USA certain structural reforms need to be undertaken, mainly in the labour market. However few EU countries have undertaken such reforms. The reason lies in the fact that those reforms are going to be...

The problem of monetary policy delegation is formulated as a two-stage game between the government and the central bank. In the first stage the government chooses the institutional design of the central bank. Monetary and fiscal policy are implemented in the second stage. When fiscal policy is...

Monetary and Fiscal policies interact in many ways. Recently the stance of fiscal policy in a number of countries has raised concerns about the risks for the outcomes of monetary policy. This paper first shows that these concerns are justified since, under ambitious fiscal policy makers,...
