Rational expectations are often used as a strong argument against policy activism, as they may undermine or neutralize the policymaker’s actions. Although this sometimes happens, rational expectations do not always imply policy invariance or ineffectiveness. In fact, in certain circumstances...

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,...

In this Paper, we explore whether heterogeneity among union members could threaten the stability of the EMU. The types of heterogeneity we consider are (1) asymmetries in the transmission of monetary and fiscal policies, and (2) differences in national preferences for price stability, output...

Of all the institutional arrangements for monetary union in Europe, the fiscal convergence criteria have proved the most difficult to achieve and the most controversial because of their presumed deflationary impact on economies already suffering high unemployment. This paper examines what fiscal...

The world's industrialised economies have become increasingly interdependent over the past 30 years. The policy implications of this mutual dependence obviously depend on the spillover effects between economies: but work on this topic has used simplified models of hypothetical economies, and has...

We argue that wages have increased so far ahead of labour productivity in East Germany as to produce a problem that will continue to hound German policy-makers for the next two decades. Despite rapid rates of capital accumulation (around 9%) and growth (around 5%) in East Germany over the coming...
